BMW M6 Convertible (2013)

The 2013 BMW M6 will share its engine with the BMW M5. It is the twin-turbocharged 4.4-liter V-8 engine first seen in the X5 M and X6 M twins. Horsepower is up five and torque is up two from the two aforementioned SUVs to 560 hp and 502 lb-ft, respectively. It is a more-dramatic increase compared to the old M6, offering 60 more hp and a whopping 119 more lb-ft of torque compared to the V-10 found in the 2010 M6. At the same time, fuel consumption and harmful emissions are reduced by approximately 30 percent compared to the old car, says BMW. Aiding in efficiency is a brake-energy recuperation system and an automatic engine start-stop function. 

The engine is mated to a seven-speed double-clutch transmission and sends its power down to an active rear differential, which takes into account the position of the gas pedal, the rotational speed of the wheels, and the car’s yaw rate to optimize power delivery by transferring it between the rear wheels. 

Design: athletic aura, powerfully taut surfaces, elegant lines.

Classical proportions, the sporty yet elegant lines of the BMW 6-Series and the familiar design language of BMW M Automobiles form the foundations for the eloquent body design of the BMW M6 Coupe and BMW M6 Convertible. Powerfully taut surfaces and precise contours underline the athletic aura of the two models, while standard-fitted Adaptive LED Headlights accentuate their progressive character. In addition, hallmark M styling cues add details which are influenced directly by technical considerations - such as the cooling air required, chassis geometry and aerodynamics - and thus further highlight the cars' outstanding performance attributes.

Both models are fitted with 19-inch M light-alloy wheels as standard. The forged wheels feature seven double-spokes in a two-tone finish, while the optional 20-inch M light-alloy wheels hint at reduced weight with their five intricate double-spokes.

Dynamic contours, lightweight material: the carbon fibre-reinforced plastic roof of the BMW M6 Coupe.

Like its predecessor, the roof of the new BMW M6 Coupe is made from carbon fibre-reinforced plastic as standard. The dark colouring of the roof gives the two-door car's silhouette an extremely elongated look, which is further emphasised by a dynamic recess in the centre of the roof. The use of the lightweight material for the roof allows the car's centre of gravity to be lowered, enhancing agility. BMW Individual High-gloss Shadow Line trim (standard) draws attention to this optimised weight balance, its dark colouring covering the side window borders (or the waistline in the case of the BMW M6 Convertible) and the base and lower section of the aerodynamically optimised M exterior mirror caps.

The exclusive looks of the new BMW 6-Series Convertible are underlined by the "fin" architecture of the high-quality soft-top roof. Projecting into the rear section, the fins accentuate the car's dynamically sweeping silhouette. The heated, vertical glass rear window, which is situated just behind the rear seats, retracts independently of the soft-top itself. The automatic opening and closing process for the roof can be activated both at a standstill and while on the move at speeds of up to 40 km/h (25 mph) using a button on the centre console. The optional Comfort Access allows the roof to be opened or closed by pressing the remote control button on the car key. It takes the roof 19 seconds to open and 24 seconds to close again.

The engine: high-revving V8 with M TwinPower Turbo technology.

The new BMW M6 Coupe and Convertible showcase their individual style with a raft of unique styling touches and tweaks to the character of the driving experience. But they draw the output required to serve up their inspirational performance from the same source: a high-revving V8 engine with M TwinPower Turbo technology, longitudinally mounted at the front of the car, whose power is channelled to the rear wheels via a seven-speed M Double Clutch Transmission with Drivelogic. This powertrain combines construction features taken directly from motor sport with innovations developed under the banner of Efficient Dynamics. Its globally unparalleled package of technology comprises two turbochargers working according to the twin-scroll principle, a cross-bank exhaust manifold, High Precision Direct Petrol Injection, VALVETRONIC variable valve timing and Double-Vanos continuously variable camshaft control.

The unmistakable, typically M performance characteristics of the 4.4-litre powerplant are defined by its lightning-quick responses and forceful, linear power delivery maintained into the higher reaches of the rev range. Indeed, peak torque of 680 Newton metres (502 lb-ft) is on tap between 1,500 and 5,750 rpm. The V8 achieves its maximum output of 412 kW/560 hp between 6,000 and 7,000 rpm and can spin on to 7,200 rpm. All of which means the rev band available in the new models to generate maximum performance is almost three times wider than that of the engine powering their predecessors.

Harnessing the high output to dynamic effect: the seven-speed M Double Clutch Transmission with Drivelogic.

Tuned seamlessly to the performance characteristics of the V8 engine, the M Double Clutch Transmission with Drivelogic converts the powerplant's impressive thrust extremely effectively into rapid acceleration. This capability is underpinned by the DCT design principle, which effectively combines two gearboxes in one housing - yet with virtually no size or weight penalty over a conventional manual transmission.

M DCT Drivelogic offers the driver three different shift programs, both in automated mode (D) and in manual mode (S). In addition, the electronics also provide a Launch Control function ensuring unbeatable acceleration from a standing start, Low Speed Assistance for easier low-speed operation, and the Auto Start-Stop function for increased efficiency. The new BMW M6 Coupe and the new BMW M6 Convertible are equipped as standard with a newly developed M leather steering wheel, complete with multifunction buttons and fixed gearshift paddles.

Active M Differential delivers outstanding traction in dynamic driving situations.

The new BMW M6 Coupe and new BMW M6 Convertible also impress by offering optimum traction in tricky road and weather conditions and under dynamic acceleration out of corners. Working behind the scenes to this end is an innovative variable locking differential in the rear differential.

The Active M Differential allows the engine's power to be split precisely and quickly between the left and right rear wheel according to the requirements of the driving situation at any particular moment. An electronically controlled multi-plate limited-slip differential helps to reduce the rotational speed differences between the rear wheels, which is needed to optimise traction. The Active M Differential control unit is linked up to the DSC stability control system, allowing every driving situation to be precisely analysed and a loss of traction at one wheel to be detected at an early stage. The locking effect generated in response can be varied between 0 and 100 per cent.

M-specific chassis technology, Dynamic Damper Control, M Servotronic, DSC with M Dynamic Mode.

The chassis of the new BMW M6 Coupe and new BMW M6 Convertible has been developed to M specification and therefore combines outstanding performance attributes with the comfort-enhancing features drivers appreciate on an everyday basis. Like the integral rear axle, whose subframes are bolted rigidly to the body, the double-wishbone front axle boasts specific kinematics and newly developed components made from forged aluminium. Chassis mountings using large panels at the front and rear axle ensure dynamic forces are passed evenly through to the body. Through enthusiastically driven corners, this helps to noticeably reduce the roll movements triggered by bumps in the road surface. Both the construction of the chassis and its bespoke tuning for each model are defined by in-depth expertise from the race track and have been optimised during extensive testing on the Nürburgring'sNordschleife circuit.

The standard equipment of both models also includes electronically controlled dampers. The M-specific Dynamic Damper Control system adjusts damping force electrohydraulically to provide the required responses for the driving situation at hand and fulfil the wishes of the driver. A choice of three settings allows drivers to adjust the damper characteristics to their needs and preferences.

The hydraulic rack-and-pinion steering ensures unbeatable precision and a high degree of comfort. This system has a variable ratio, which enhances straightline stability and reduces the number of steering wheel turns required when parking and turning off a road. The likewise standard Servotronic speedsensitive power assistance is specially tuned to M specification and enables drivers to choose a personal configuration with the help of three set-up options.

In addition to applying brake impulses and reducing engine output to stabilise the car, the DSC stability control system of the two high-performance sports cars also employs the services of the Anti-lock Braking System (ABS), Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake Assistant, the Brake Drying function and Start-Off Assistant. M Dynamic Mode (MDM) can be activated to override the basic setting by pressing the DSC button. By raising the intervention thresholds of DSC, this mode makes it easier to move off on snow or loose sand with slightly spinning driven wheels. MDM mode also paves the way for the familiar M self-steering response. "DSC Off" mode can likewise be activated at the touch of a button.

An innovation designed to deliver precise handling: M carbon-ceramic brakes.

The latest version of the compound high-performance braking system helps give the new BMW M6 Coupe and new BMW M6 Convertible outstanding stopping power. Its stand-out features include even lower weight, excellent feel and fade-free performance even under heavy loads. The diameter of the inner-vented and perforated brake discs is 400 millimetres at the front and 396 millimetres at the rear. The six-piston fixed-calliper brakes at the front axle - painted dark blue metallic and complete with the M logo - are radially bolted to the pivot bearing.

As an alternative to the standard compound high-performance braking system, M carbon-ceramic brakes make their debut in the new BMW M6 Coupe and new BMW M6 Convertible. They are available in conjunction with 20-inch M light-alloy wheels and feature brake discs measuring 410 millimetres in diameter at the front axle and 396 millimetres at the rear. Made from a new type of carbon-fibre compound ceramic, the discs boast even greater resistance to heat and combine this with significantly reduced rotating masses. The innovative material also displays exceptional resistance to wear.

The optional M carbon-ceramic system also sees six-piston fixed-calliper brakes at the front teaming up with single-piston floating-calliper brakes at the rear. The callipers can be identified by their special gold-coloured paint finish.

Lightweight design, seamless occupant protection.

An intelligent blend of materials also gives the body structure impressive strength coupled with extremely low weight. As with the use of CFRP for the roof of the new BMW M6 Coupe, the choice of materials for all other body components slots into the all-round lightweight design strategy. The doors and bonnet of the two high-performance sports cars are made from aluminium, the front side panels from thermoplastic. In addition, their boot lids and - in the case of the BMW M6 Convertible - also the roof cover are made from the glass-fibre composite material SMC (Sheet Moulding Compound).

A weight-to-power ratio of 3.3 kg/hp for the new BMW M6 Coupe and 3.5 kg/hp for the new BMW M6 Convertible is a significant improvement over the predecessor models.

Robust load-path structures, large and precisely defined deformation zones and highly efficient restraint systems provide the basis for a high level of passive safety in both models. The safety equipment fitted as standard includes front and side airbags, side curtain head airbags for both rows of seats in the new BMW M6 Coupe, and front airbags and head-thorax side airbags integrated into the seat frames of the new BMW M6 Convertible. The soft-top model also benefits from roll-over bars made from high-strength aluminium. Both models also come with three-point inertia-reel seat belts on all seats, belt force limiters and belt tensioners for the front seats and ISOFIX child seat attachments in the rear.

The two high-performance models are designed as four-seaters, and space in the rear compartment has increased substantially compared with the predecessor models. The load capacity of the new BMW M6 Coupe stands at 460 litres. The new BMW M6 Convertible, meanwhile, can accommodate 300 litres of luggage in the boot with the soft-top down and 350 litres with it closed.

Individual set-up configuration, two M Drive buttons on the steering wheel.

Also contributing to the familiar M feeling is the model-specific interior design whose stand-out features include newly developed M sports seats and an M-specific cockpit, along with buttons to adjust the DSC mode, engine performance characteristics, damper mapping, M Servotronic responses and shift program. Individually configured settings can be saved by means of two M Drive buttons on the steering wheel and called up as required.

Available as an option are the BMW Head Up-Display with M-specific information along with an extensive range of other driver assistance systems from BMW ConnectedDrive, such as Park Distance Control, rear-view camera, High Beam Assistant, Speed Limit Info, Lane Change Warning, Lane Departure Warning, Surround View and BMW Night Vision with pedestrian recognition. The choice of equipment options also includes M multifunction seats, the navigation system Professional and the Bang & Olufsen High End Surround Sound System.

2013 BMW M550d xDrive

2013 BMW M550d xDrive .BMW at the Geneva show its first new models powered by three turbo diesel engines – 2012 BMW M550d xDrive. 2012 BMW M550d xDrive equipped with a 3.0L straight 6 3 turbo diesel engine, the biggest horsepower 381ps 4,000 ~ 4,400 rpm, peak torque output of up to 740Nm  2,000 ~ 3,000 rpm; transmission system for the eight-speed automatic gearbox, xDrive four wheel-drive system; 0-100km / h acceleration in just 4.7 seconds (4.9 seconds for the wagon models), accelerates from zero to 1 km distance also just 23.7 seconds (wagon paragraph 24.1 seconds), top speed is electronically limited to 250km / h.

Most powerful engine of its kind, sportiest diesel models in the segment.

The new and globally unique M Performance TwinPower Turbo technology gives the six-cylinder in-line diesel engine powering the BMW M550d xDrive and BMW M550d xDrive Touring maximum output of 280 kW/381 hp and peak torque of 740 Newton metres (546 lb-ft). The engine's instantaneous and sustained wave of torque allows it to lay down benchmark performance values for diesel-powered executive cars. The BMW M550d xDrive Sedan goes from 0 to 100 km/h (62 mph) in 4.7 seconds, while the BMW M550d xDrive Touring records 4.9 seconds for the same sprint. The duo also display addictive elasticity at higher speeds thanks to their engine's vast reserves of power. Top speed is electronically limited to 250 km/h (155 mph) in both cases.

The diesel technology developed exclusively for the BMW M Performance Automobiles also gives the new arrivals a convincing head start in terms of efficiency. The Sedan offers fuel economy figures of 6.3 litres per 100 kilometres (44.8 mpg imp) in the EU test cycle, while the Touring achieves 6.4 l/100 km (44.1 mpg imp). CO2 emissions are 165 grams per kilometre for the BMW M550d xDrive Sedan and 169 g/km in the case of the BMW M550d xDrive Touring. Standard-fitted BMW BluePerformance technology also allows the two models to meet the stipulations of the EU6 exhaust standard.

The new cars' outstanding balance between driving pleasure and fuel consumption can be credited to the impressive efficiency of the new diesel powerplant and the spread of BMW EfficientDynamics technology fitted as standard. The BMW M550d xDrive and BMW M550d xDrive Touring benefit, among other things, from the pace-setting efficiency of an eight-speed Sports automatic transmission with long high gears, precisely graded responses and minimal converter slip. Another standard feature, the Auto Start-Stop function, switches the engine off automatically when the driver stops at junctions or in congestion. And the ECO PRO mode activated using the standard Driving Experience Control switch helps the driver maintain an economical and relaxed driving style through tweaks to the engine management, accelerator responses and gearshift program. In addition, ECO PRO mode regulates the output of electrically operated functions such as the climate control, heated seats and exterior mirrors to provide extremely efficient energy management. The BMW M550d xDrive and BMW M550d xDrive Touring also come with Brake Energy Regeneration, need-based operation of ancillary units, active air flap control and a disengageable air conditioning compressor.

BMW xDrive all-wheel drive with special M set-up.

The BMW M Performance Automobiles come as standard with BMW xDrive to channel the engine's power variably and as the situation demands between the front and rear wheels. The electronically controlled all-wheel-drive system works using a bespoke control strategy, which allows the threat of understeer in extremely dynamic driving situations to be counteracted by adjustments to the power split, without the DSC (Dynamic Stability Control) system linked up to xDrive having to intervene. The system's M-specific tuning accentuates the traditional rear-wheel bias of BMW cars when it comes to power distribution.

The all-wheel-drive system of the BMW M550d xDrive and BMW M550d xDrive Touring sends more drive to the rear axle on the entry into a corner, delivering exceptionally precise cornering and impressive directional stability. In addition, the likewise standard Performance Control divides power between the rear wheels to maximise the cars' sports performance. Carefully judged braking of the rear wheel nearest the inside of the bend coupled with a simultaneous increase in drive power ensure the car responds to the driver's steering commands instantaneously and with high precision. The driver can even use the self-steering response typical of M cars to execute controlled drifts through dynamically taken corners.

Hallmark M chassis tuning delivers precise, agile handling.

The chassis technology of the BMW M550d xDrive and BMW M550d xDrive Touring is based on a double-wishbone front axle and integral rear axle. In addition, the Touring model has air suspension with automatic self-levelling at the rear axle. The suspension, spring and damper system, and hydraulic steering with Servotronic function also benefit from M-specific tuning. The associated modifications imbue both models with a fresh take on the traditional M handling characteristics, the cars' agility under lateral and longitudinal acceleration - and the precision of its responses to steering commands - entering a new dimension.

Special rubber bearings and anti-roll bars optimise the bodyshell mounting of the BMW M550d xDrive and BMW M550d xDrive Touring. Plus, modified springs and dampers give the two models tighter basic responses to dynamic forces. Optimised anti-roll control promotes instantaneous turn-in at any speed. The build-up of lateral forces under changes in direction is pleasingly linear and can therefore be controlled at all times. All of which means the BMW M Performance Automobiles also preserve the familiar comfort-enhancing properties of the BMW 5-Series when it comes to ironing out bumps and ruts in the road surface. If the optional Dynamic Damper Control or Adaptive Drive system is specified, COMFORT+ mode can also be selected using the Driving Experience Control switch. The M-specific overall set-up of the BMW M Performance Automobiles also includes modifications to the tuning of the electronically controlled dampers and anti-roll control. The result is a well-resolved, typically M overall set-up regardless of the equipment options chosen.

The powerful braking system on the BMW M550d xDrive and BMW M550d xDrive Touring features inner-vented discs; like the discs charged with stopping the V8 petrol-engined BMW 550i, they have a diameter of 374 millimetres at the front axle and 345 millimetres at the rear. The standard 19-inch M light-alloy wheels in double-spoke design are fitted with 245/40 R 19 format tyres. 20-inch M light-alloy wheels - developed exclusively for the BMW M Performance Automobiles - with mixed tyres can be ordered as an option.

Exclusive sporting character outside and in.

Another feature of the typically M overall set-up are the aerodynamic characteristics of the body, which help to give the BMW M550d xDrive and BMW M550d xDrive Touring their precisely controllable dynamics. The sporty yet elegant appearance of the two cars is complemented by a bespoke, airflow-optimising design for the front and rear aprons. The front view of both models is dominated by large air intakes. For example, the spaces around the outer air intakes normally reserved for foglamps on regular BMW 5-Series models are used to enhance the inflow of cooling air. The three-dimensional shaping of the front apron incorporates air-channelling flaps at the lower edge of the outer intakes, which are split horizontally by bars painted Ferric Grey metallic. The same shade is used for the exterior mirror caps and optional 20-inch M light-alloy wheels. BMW Individual High-gloss Shadow Line trim for the B-pillars, exterior mirror base and window surrounds also comes as standard.

Its extremely powerful form and an integrated diffuser element allow the bespoke rear apron of the BMW M550d xDrive and BMW M550d xDrive Touring to optimise both the cars' sporting appearance and airflow around the underbody. A horizontal trim strip on the top edge of the Black insert accentuates the width of the body. The exhaust tailpipes, positioned far to the outer edges of the rear end, come with trapezoidal embellishers in Chrome Dark. Another distinguishing feature is the "M550d" lettering on the boot lid and front door sills.

Lending the interior a familiar M ambience are features such as the gearshift lever with M logo, M leather steering wheel with gearshift paddles, M driver's footrest, BMW Individual roof liner in Anthracite and Aluminium Hexagon interior trim strips. The sports seats in the exclusive M variant Alcantara/Cloth in Grey Shadow are adorned with contrast stitching and an embossed M logo. Dakota leather is available as an alternative, at no extra cost.

The standard equipment of the BMW M550d xDrive and BMW M550d xDrive Touring also includes xenon headlights, Cruise Control with braking function, electrically adjustable seats with memory function for the driver's seat, 4-zone climate control, a rain sensor, the Radio Professional, a hands-free facility with USB interface, ambient light and the iDrive control system. High-quality options such as Comfort Access, automatic tailgate operation (standard in Germany on the BMW M550d xDrive Touring), hands-free tailgate opening, electrically operated glass/panoramic sunroof, doors with Soft Close Automatic function, trailer coupling, heated steering wheel, active seats, navigation systems with hard disk storage, and high-quality audio and rear-seat entertainment systems deliver a further boost to comfort.

Almost all of the BMW ConnectedDrive driver assistance systems and mobility services laid on for the BMW 5-Series can also be specified here. Features such as the Park Distance Control system, rear-view camera, Adaptive Headlights, Head-Up Display, High-Beam Assistant, Active Cruise Control with Stop & Go function, Speed Limit Info, Lane Change Warning System, Lane Departure Warning System, Surround View and BMW Night Vision with pedestrian recognition are all available. Other innovative technologies enabling the link-up of the car with the outside world and the integration of mobile devices give drivers access to, among other things, the BMW Assist service (including Advanced Emergency Call with automatic position finding), BMW Online and internet, as well as the online services Facebook and Twitter, and Real-Time Traffic Information.

The powertrain: The most innovative and sporty diesel engine in the world.

Impressive statistics headline the enviable regard in which modern diesel engines are held. The output now within their compass, but more significantly the maximum torque they are capable of generating have fuelled their popularity among even performance-minded drivers. The high efficiency of diesel technology also ensures extremely low fuel consumption and CO2 emissions. BMW has played a major role in the burgeoning appeal of the diesel engine, developing units which have time and again raised the bar in terms of sports performance and efficiency. The company's record of diesel engine development, which began in 1983 with the launch of its first diesel model, now continues into another fascinating dimension. The first of the new BMW M Performance Automobiles - founding a product category focusing on sporty driving pleasure - are powered by a diesel engine. The 3.0-litre six-cylinder in-line unit, whose cover bears the M Performance badge, has all the necessary tools to fulfil the brief handed to the new breed: technology without parallel worldwide, the highest output ever achieved by a BMW diesel engine and outstanding levels of efficiency.

Fitted in the BMW M550d xDrive, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d, the 2,993 cc engine generates maximum output of 280 kW/381 hp. No less imposing is its peak torque of 740 Newton metres (546 lb-ft), all of which the driver will find on tap as low down as 2,000 rpm. Instantaneous torque development maintained into the upper reaches of the rev range is the hallmark feature of the new unit, one underpinned by an array of innovative and globally unique technical wizardry. Taking centre stage - for the first time in a BMW - are a trio of turbochargers. Their arrangement and interplay strategy are the key to the engine achieving its exceptionally high efficiency.

More pressure, more output, more torque: world premiere for six-cylinder in-line diesel engine with three turbochargers.

The coordinated interplay of turbochargers of different sizes endows an engine with instantaneous responsiveness at low revs and allows charge pressure to be increased according to need when the engine is placed under greater loads. BMW uses this concept in the six-cylinder in-line diesel engines with BMW TwinPower Turbo technology fitted in models including the BMW 535d, BMW X5 xDrive40d and BMW X6 xDrive40d. And now the company is set to become the world's first carmaker to present a diesel engine which expands the principle of multi-stage turbocharging to incorporate a third turbocharger. The engine developed for the BMW M Performance Automobiles will, for the first time, see two comparatively small high-pressure chargers working with a larger low-pressure unit. The integration of an additional high-pressure turbo increases the engine's capability when it comes to generating charge pressure, a key ingredient in taking the engine's power output to the next level.

The M Performance TwinPower Turbo technology - including the requisite charge air cooling - is, like its predecessor, integrated into a small space in the main unit. Its compact construction puts the engine in a position to meet future pedestrian protection stipulations, while the arrangement of the three turbochargers is also part of an extremely intelligent system. Both the exhaust inflow to drive the turbos and the supply of fresh air, plus the channelling of compressed air to the combustion chambers, have been designed to ensure that the three compression units work as a team as effectively as possible at all engine speeds. Efficiency is further optimised by the variable turbine geometry of the two high-pressure chargers, which allows them to react even more precisely to the driver's power needs.

Instantaneous responsiveness and precisely coordinated interplay.

One of the two small turbos is activated at engine speeds just above idle. Its low moment of inertia allows it to respond without delay to the slightest movements of the accelerator and therefore supply the combustion chambers with compressed air at an early stage. As revs increase, the flow of exhaust gas also reaches the larger turbocharger, which announces its arrival with the engine spinning at just 1,500 rpm. Working together with the small charger, it ensures that the impressive peak torque of 740 Newton metres (546 lb-ft) is generated at this low engine speed and maintained up to 3,000 rpm.

To further increase the performance of the large turbocharger, a greater volume of exhaust gas is required at around 2,700 rpm. If the driver calls up additional power, a vacuum-modulated exhaust flap instantly opens up another supply route, allowing extra exhaust gas to flow past the already active high-pressure charger to the large low-pressure turbo. The third turbocharger - integrated into this bypass line - also has a low moment of inertia and variable compressor geometry, which allow it to spring into action as soon as the exhaust flap opens. The result is additional charge pressure, generated by two sources at the same time. The large turbocharger is able to deliver its full output, while the second small turbo builds on the effect of its two active colleagues by supplying even more compressed air to the combustion chambers. This arrangement allows the turbocharging system to drive the engine with forceful and sustained thrust to its maximum output of 280 kW/381 hp, which it notches up between 4,000 and 4,400 rpm. The maximum engine speed of the new diesel powerplant is 5,400 rpm.

In order to ensure that charge pressure is developed as effectively as possible, not to mention efficiently, both the exhaust flow and supply of fresh air to the turbos and the channelling of compressed air into the combustion chambers is regulated with maximum precision. If the large turbocharger is spinning at particularly high speeds, a vacuum regulator opens a wastegate valve to relieve the pressure and so avoid unwanted exhaust backpressure. The supply of fresh air is also controlled according to need by means of pneumatically activated flaps. For example, at low revs a bypass flap ensures that the air is channelled directly to the high-pressure charger, which spins into action very early. At less than 2,700 rpm a change-over flap keeps the air away from the third turbo, which is not yet active, to prevent unnecessary fluctuations in pressure.

Indirect charge air cooling enables the temperature of the air compressed by the three turbos to be reduced to the optimum level for increasing engine output. Both the main radiator positioned immediately in front of the combustion chambers and the intercooler behind the low-pressure charger are supplied by a low-temperature water circuit with separate electric pump.

Detailed optimisation enables higher combustion pressure, increased output and enhanced efficiency.

The new torquey and high-revving diesel engine also breaks new ground with its specific output of 93.6 kW per litre of displacement. However, the output possible using M Performance TwinPower Turbo technology is generated not in the turbochargers but in the core of the basic engine, which has therefore also been extensively modified. Maximum combustion pressure has risen from the 185 bar of the most powerful diesel engine in the existing BMW line-up to 200 bar.

As part of this development, the crankcase in the new 3.0-litre diesel engine features an innovative tie rod concept for the assembly of the main bearing caps and cylinder head. The sintered main bearing caps are given extra strength by a central screw. Like the crankcase, the cylinder head is also subjected to a special high-pressure compression process. This "HIPen" manufacturing concept sees the aluminium castings heated to solution annealing temperature and the casting pores created during manufacturing welded under high pressure. This process gives the finished component additional strength. A double diagonal bore ensures the interbore bridges have high thermal stability.

The geometry of the crankshaft and connecting rods has been further optimised and they are now made from higher-strength materials. Added to which, hub bushings and bowl rim remelting enhance the effect of the increase in piston compression height.

Higher pressure also raises the efficiency of the injection system.

The injection system of the new six-cylinder in-line diesel engine has also benefited from a rigorous process of further development. The common-rail direct injection system plays its part in enhancing the engine's efficiency and promoting clean combustion by sending extremely precise quantities of fuel into the cylinders. The upgraded system raises the injection pressure of the piezo injectors to 2,200 bar. During each power stroke, three pre-injections, one main injection and four post-injections of fuel take place. An ultra-high-performance pump channels the fuel to the combustion chambers through a common rail made from forged stainless steel.

The output and capacity of the cooling system have been given another boost, too. An additional low-temperature circuit supplied by an electric water pump controls the temperature of the intercoolers. The exhaust treatment system includes a diesel particulate filter and oxidation catalytic converter, which is located close to the engine in the same casing. More efficient exhaust cooling, meanwhile, minimises the formation of nitrogen oxides. And standard-fitted BMW BluePerformance technology, which includes a NOX storage catalytic converter, helps the new diesel engine powering the BMW M550d xDrive to meet the EU6 exhaust standard not due to come into force until 2014.

Eight-speed Sports automatic transmission with M-specific gearshift dynamics.

The combination of the most powerful diesel engine ever offered for a BMW with an eight-speed Sports automatic transmission ensures that drive is transferred onto the road surface extremely effectively and efficiently. The configuration of the transmission management system for the BMW M Performance Automobiles promotes dynamic acceleration. The M-specification gearshift dynamics enable extremely rapid gear changes with an almost uninterrupted flow of power. The eight-speed Sports automatic transmission offers the driver two automated shift programs - D and S modes - as well as the option of changing gear manually (in M mode).

The automatic gearbox is operated using an electronic gearshift lever on the centre console adorned with an M logo. Manual mode allows the driver to change gears sequentially using either the gearshift lever or the paddles on the steering wheel. In customary M fashion, the right-hand paddle changes up a gear and the left-hand paddle is used for downshifts. If the driver activates manual mode using the gearshift lever, the transmission holds the gear selected until the engine's revs hit the limiter. By not shifting up automatically in this mode, the gearbox gives the driver maximum control over the car when pushing the dynamic boundaries. The driver can also switch instantaneously from automatic gear changes to M mode with a nudge of one of the gearshift paddles; if M mode is selected in this way, the gearbox's automatic shift-up function remains active. The transmission also restores automatic mode if the gearshift paddles are not used again following an upshift or downshift.

Enhancing the natural soundtrack inside the car turns driving pleasure up yet another notch.

The performance capability of the diesel engine and the hallmark M driving characteristics of the BMW M Performance Automobiles underpin a new definition of driving pleasure. Imposing torque and a set-up focused squarely on sports performance give drivers a dynamic driving experience they will never have previously sampled in a diesel car. The BMW M Performance Automobiles also lace this driving pleasure with additional acoustic appeal. Through sound design technology, the natural engine sound is specifically enhanced to suit the driving situation at the time and sent into the interior via the audio system, ensuring an authentic reproduction of the new engine's unmistakable straight-six soundtrack.

The system's digital signal processing technology exchanges data directly with the engine management, allowing it to base its precise transmission of the engine's timbre on the revs at any one time, the amount of torque being produced and the car's speed over the road. Accentuating the straight-six diesel's turbine-like, sporty and sonorous tones adds to the emotional appeal of the driving experience, especially in the BMW M550d xDrive when SPORT or SPORT+ mode is activated using the Driving Experience Control switch. This gives the driver an impressively accurate impression of how hard the engine is currently working and of the power being unleashed, and provides an even clearer window into the car's responses on the road. Controlling the audio system in this way also ensures that the engine sound can be enjoyed to equal effect from every seat.

New six-cylinder engine with three turbochargers - a milestone in the glittering history of BMW diesel engines.

The engine developed for the BMW M Performance Automobiles represents a new high water mark in the illustrious history of diesel engines at BMW. The premium carmaker has offered customers diesel-powered models since 1983. The BMW 524td that kicked off this fine tradition quickly earned itself the status of the sportiest diesel model on the market. Its engine developed 85 kW/115 hp and delivered the best performance yet also the lowest fuel consumption of any car in its class. Since then, diesel BMWs have regularly emerged as the most efficient models in head-to-head tests. A host of prestigious awards - such as the Engine of the Year Award - and the impressive success of diesel-powered BMW models on the track headline the company's unrivalled expertise in the development of diesel technology.

And so it is entirely in keeping with the company's proud heritage that the first BMW M Performance Automobiles are now set to line up with a diesel engine under the bonnet. The unit developed to power them fulfils its sporting brief with leading performance in a range of disciplines and, in so doing, dismantles the historic contradiction between driving pleasure and economy even more effortlessly than ever.

BMW M550d xDrive (2013)

BMW M GmbH today introduced a new product range of performance-oriented diesel models that will go on sale in Europe later this year. The BMW M Performance Automobiles will launch with four new models including the BMW M550d xDrive Sedan, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d.

All of the new models are powered by a completely new 3.0 liter 6-clyinder in-line diesel engine with M Performance TwinPower Turbo technology which consists of three turbochargers. Output comes in at 381-hp at 4,000 rpm and a maximum torque of 546 lb-ft between 2,000 – 3,000 rpm. All models are also mated to a 8-speed automatic transmission with enhanced gearshift dynamics fitted as standard on all BMW M Performance Automobiles.

As the naming for the models suggest all of them come with BMW xDrive intelligent all-wheel-drive – the BMW M550d xDrive comes as standard with the Driving Experience Control switch, including ECO PRO mode; BMW M550d xDrive Touring also features air suspension on the rear axle and automatic self-levelling; both models available as an option with Dynamic Damper Control and Adaptive Drive including anti-roll control.

Most powerful engine of its kind, sportiest diesel models in the segment.

The new and globally unique M Performance TwinPower Turbo technology gives the six-cylinder in-line diesel engine powering the BMW M550d xDrive and BMW M550d xDrive Touring maximum output of 280 kW/381 hp and peak torque of 740 Newton metres (546 lb-ft). The engine's instantaneous and sustained wave of torque allows it to lay down benchmark performance values for diesel-powered executive cars. The BMW M550d xDrive Sedan goes from 0 to 100 km/h (62 mph) in 4.7 seconds, while the BMW M550d xDrive Touring records 4.9 seconds for the same sprint. The duo also display addictive elasticity at higher speeds thanks to their engine's vast reserves of power. Top speed is electronically limited to 250 km/h (155 mph) in both cases.

The diesel technology developed exclusively for the BMW M Performance Automobiles also gives the new arrivals a convincing head start in terms of efficiency. The Sedan offers fuel economy figures of 6.3 litres per 100 kilometres (44.8 mpg imp) in the EU test cycle, while the Touring achieves 6.4 l/100 km (44.1 mpg imp). CO2 emissions are 165 grams per kilometre for the BMW M550d xDrive Sedan and 169 g/km in the case of the BMW M550d xDrive Touring. Standard-fitted BMW BluePerformance technology also allows the two models to meet the stipulations of the EU6 exhaust standard.

The new cars' outstanding balance between driving pleasure and fuel consumption can be credited to the impressive efficiency of the new diesel powerplant and the spread of BMW EfficientDynamics technology fitted as standard. The BMW M550d xDrive and BMW M550d xDrive Touring benefit, among other things, from the pace-setting efficiency of an eight-speed Sports automatic transmission with long high gears, precisely graded responses and minimal converter slip. Another standard feature, the Auto Start-Stop function, switches the engine off automatically when the driver stops at junctions or in congestion. And the ECO PRO mode activated using the standard Driving Experience Control switch helps the driver maintain an economical and relaxed driving style through tweaks to the engine management, accelerator responses and gearshift program. In addition, ECO PRO mode regulates the output of electrically operated functions such as the climate control, heated seats and exterior mirrors to provide extremely efficient energy management. The BMW M550d xDrive and BMW M550d xDrive Touring also come with Brake Energy Regeneration, need-based operation of ancillary units, active air flap control and a disengageable air conditioning compressor.

BMW xDrive all-wheel drive with special M set-up.

The BMW M Performance Automobiles come as standard with BMW xDrive to channel the engine's power variably and as the situation demands between the front and rear wheels. The electronically controlled all-wheel-drive system works using a bespoke control strategy, which allows the threat of understeer in extremely dynamic driving situations to be counteracted by adjustments to the power split, without the DSC (Dynamic Stability Control) system linked up to xDrive having to intervene. The system's M-specific tuning accentuates the traditional rear-wheel bias of BMW cars when it comes to power distribution.

The all-wheel-drive system of the BMW M550d xDrive and BMW M550d xDrive Touring sends more drive to the rear axle on the entry into a corner, delivering exceptionally precise cornering and impressive directional stability. In addition, the likewise standard Performance Control divides power between the rear wheels to maximise the cars' sports performance. Carefully judged braking of the rear wheel nearest the inside of the bend coupled with a simultaneous increase in drive power ensure the car responds to the driver's steering commands instantaneously and with high precision. The driver can even use the self-steering response typical of M cars to execute controlled drifts through dynamically taken corners.

Hallmark M chassis tuning delivers precise, agile handling.

The chassis technology of the BMW M550d xDrive and BMW M550d xDrive Touring is based on a double-wishbone front axle and integral rear axle. In addition, the Touring model has air suspension with automatic self-levelling at the rear axle. The suspension, spring and damper system, and hydraulic steering with Servotronic function also benefit from M-specific tuning. The associated modifications imbue both models with a fresh take on the traditional M handling characteristics, the cars' agility under lateral and longitudinal acceleration - and the precision of its responses to steering commands - entering a new dimension.

Special rubber bearings and anti-roll bars optimise the bodyshell mounting of the BMW M550d xDrive and BMW M550d xDrive Touring. Plus, modified springs and dampers give the two models tighter basic responses to dynamic forces. Optimised anti-roll control promotes instantaneous turn-in at any speed. The build-up of lateral forces under changes in direction is pleasingly linear and can therefore be controlled at all times. All of which means the BMW M Performance Automobiles also preserve the familiar comfort-enhancing properties of the BMW 5-Series when it comes to ironing out bumps and ruts in the road surface. If the optional Dynamic Damper Control or Adaptive Drive system is specified, COMFORT+ mode can also be selected using the Driving Experience Control switch. The M-specific overall set-up of the BMW M Performance Automobiles also includes modifications to the tuning of the electronically controlled dampers and anti-roll control. The result is a well-resolved, typically M overall set-up regardless of the equipment options chosen.

The powerful braking system on the BMW M550d xDrive and BMW M550d xDrive Touring features inner-vented discs; like the discs charged with stopping the V8 petrol-engined BMW 550i, they have a diameter of 374 millimetres at the front axle and 345 millimetres at the rear. The standard 19-inch M light-alloy wheels in double-spoke design are fitted with 245/40 R 19 format tyres. 20-inch M light-alloy wheels - developed exclusively for the BMW M Performance Automobiles - with mixed tyres can be ordered as an option.

Exclusive sporting character outside and in.

Another feature of the typically M overall set-up are the aerodynamic characteristics of the body, which help to give the BMW M550d xDrive and BMW M550d xDrive Touring their precisely controllable dynamics. The sporty yet elegant appearance of the two cars is complemented by a bespoke, airflow-optimising design for the front and rear aprons. The front view of both models is dominated by large air intakes. For example, the spaces around the outer air intakes normally reserved for foglamps on regular BMW 5-Series models are used to enhance the inflow of cooling air. The three-dimensional shaping of the front apron incorporates air-channelling flaps at the lower edge of the outer intakes, which are split horizontally by bars painted Ferric Grey metallic. The same shade is used for the exterior mirror caps and optional 20-inch M light-alloy wheels. BMW Individual High-gloss Shadow Line trim for the B-pillars, exterior mirror base and window surrounds also comes as standard.

Its extremely powerful form and an integrated diffuser element allow the bespoke rear apron of the BMW M550d xDrive and BMW M550d xDrive Touring to optimise both the cars' sporting appearance and airflow around the underbody. A horizontal trim strip on the top edge of the Black insert accentuates the width of the body. The exhaust tailpipes, positioned far to the outer edges of the rear end, come with trapezoidal embellishers in Chrome Dark. Another distinguishing feature is the "M550d" lettering on the boot lid and front door sills.

Lending the interior a familiar M ambience are features such as the gearshift lever with M logo, M leather steering wheel with gearshift paddles, M driver's footrest, BMW Individual roof liner in Anthracite and Aluminium Hexagon interior trim strips. The sports seats in the exclusive M variant Alcantara/Cloth in Grey Shadow are adorned with contrast stitching and an embossed M logo. Dakota leather is available as an alternative, at no extra cost.

The standard equipment of the BMW M550d xDrive and BMW M550d xDrive Touring also includes xenon headlights, Cruise Control with braking function, electrically adjustable seats with memory function for the driver's seat, 4-zone climate control, a rain sensor, the Radio Professional, a hands-free facility with USB interface, ambient light and the iDrive control system. High-quality options such as Comfort Access, automatic tailgate operation (standard in Germany on the BMW M550d xDrive Touring), hands-free tailgate opening, electrically operated glass/panoramic sunroof, doors with Soft Close Automatic function, trailer coupling, heated steering wheel, active seats, navigation systems with hard disk storage, and high-quality audio and rear-seat entertainment systems deliver a further boost to comfort.

Almost all of the BMW ConnectedDrive driver assistance systems and mobility services laid on for the BMW 5-Series can also be specified here. Features such as the Park Distance Control system, rear-view camera, Adaptive Headlights, Head-Up Display, High-Beam Assistant, Active Cruise Control with Stop & Go function, Speed Limit Info, Lane Change Warning System, Lane Departure Warning System, Surround View and BMW Night Vision with pedestrian recognition are all available. Other innovative technologies enabling the link-up of the car with the outside world and the integration of mobile devices give drivers access to, among other things, the BMW Assist service (including Advanced Emergency Call with automatic position finding), BMW Online and internet, as well as the online services Facebook and Twitter, and Real-Time Traffic Information.

The powertrain: The most innovative and sporty diesel engine in the world.

Impressive statistics headline the enviable regard in which modern diesel engines are held. The output now within their compass, but more significantly the maximum torque they are capable of generating have fuelled their popularity among even performance-minded drivers. The high efficiency of diesel technology also ensures extremely low fuel consumption and CO2 emissions. BMW has played a major role in the burgeoning appeal of the diesel engine, developing units which have time and again raised the bar in terms of sports performance and efficiency. The company's record of diesel engine development, which began in 1983 with the launch of its first diesel model, now continues into another fascinating dimension. The first of the new BMW M Performance Automobiles - founding a product category focusing on sporty driving pleasure - are powered by a diesel engine. The 3.0-litre six-cylinder in-line unit, whose cover bears the M Performance badge, has all the necessary tools to fulfil the brief handed to the new breed: technology without parallel worldwide, the highest output ever achieved by a BMW diesel engine and outstanding levels of efficiency.

Fitted in the BMW M550d xDrive, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d, the 2,993 cc engine generates maximum output of 280 kW/381 hp. No less imposing is its peak torque of 740 Newton metres (546 lb-ft), all of which the driver will find on tap as low down as 2,000 rpm. Instantaneous torque development maintained into the upper reaches of the rev range is the hallmark feature of the new unit, one underpinned by an array of innovative and globally unique technical wizardry. Taking centre stage - for the first time in a BMW - are a trio of turbochargers. Their arrangement and interplay strategy are the key to the engine achieving its exceptionally high efficiency.

More pressure, more output, more torque: world premiere for six-cylinder in-line diesel engine with three turbochargers.

The coordinated interplay of turbochargers of different sizes endows an engine with instantaneous responsiveness at low revs and allows charge pressure to be increased according to need when the engine is placed under greater loads. BMW uses this concept in the six-cylinder in-line diesel engines with BMW TwinPower Turbo technology fitted in models including the BMW 535d, BMW X5 xDrive40d and BMW X6 xDrive40d. And now the company is set to become the world's first carmaker to present a diesel engine which expands the principle of multi-stage turbocharging to incorporate a third turbocharger. The engine developed for the BMW M Performance Automobiles will, for the first time, see two comparatively small high-pressure chargers working with a larger low-pressure unit. The integration of an additional high-pressure turbo increases the engine's capability when it comes to generating charge pressure, a key ingredient in taking the engine's power output to the next level.

The M Performance TwinPower Turbo technology - including the requisite charge air cooling - is, like its predecessor, integrated into a small space in the main unit. Its compact construction puts the engine in a position to meet future pedestrian protection stipulations, while the arrangement of the three turbochargers is also part of an extremely intelligent system. Both the exhaust inflow to drive the turbos and the supply of fresh air, plus the channelling of compressed air to the combustion chambers, have been designed to ensure that the three compression units work as a team as effectively as possible at all engine speeds. Efficiency is further optimised by the variable turbine geometry of the two high-pressure chargers, which allows them to react even more precisely to the driver's power needs.

Instantaneous responsiveness and precisely coordinated interplay.

One of the two small turbos is activated at engine speeds just above idle. Its low moment of inertia allows it to respond without delay to the slightest movements of the accelerator and therefore supply the combustion chambers with compressed air at an early stage. As revs increase, the flow of exhaust gas also reaches the larger turbocharger, which announces its arrival with the engine spinning at just 1,500 rpm. Working together with the small charger, it ensures that the impressive peak torque of 740 Newton metres (546 lb-ft) is generated at this low engine speed and maintained up to 3,000 rpm.

To further increase the performance of the large turbocharger, a greater volume of exhaust gas is required at around 2,700 rpm. If the driver calls up additional power, a vacuum-modulated exhaust flap instantly opens up another supply route, allowing extra exhaust gas to flow past the already active high-pressure charger to the large low-pressure turbo. The third turbocharger - integrated into this bypass line - also has a low moment of inertia and variable compressor geometry, which allow it to spring into action as soon as the exhaust flap opens. The result is additional charge pressure, generated by two sources at the same time. The large turbocharger is able to deliver its full output, while the second small turbo builds on the effect of its two active colleagues by supplying even more compressed air to the combustion chambers. This arrangement allows the turbocharging system to drive the engine with forceful and sustained thrust to its maximum output of 280 kW/381 hp, which it notches up between 4,000 and 4,400 rpm. The maximum engine speed of the new diesel powerplant is 5,400 rpm.

In order to ensure that charge pressure is developed as effectively as possible, not to mention efficiently, both the exhaust flow and supply of fresh air to the turbos and the channelling of compressed air into the combustion chambers is regulated with maximum precision. If the large turbocharger is spinning at particularly high speeds, a vacuum regulator opens a wastegate valve to relieve the pressure and so avoid unwanted exhaust backpressure. The supply of fresh air is also controlled according to need by means of pneumatically activated flaps. For example, at low revs a bypass flap ensures that the air is channelled directly to the high-pressure charger, which spins into action very early. At less than 2,700 rpm a change-over flap keeps the air away from the third turbo, which is not yet active, to prevent unnecessary fluctuations in pressure.

Indirect charge air cooling enables the temperature of the air compressed by the three turbos to be reduced to the optimum level for increasing engine output. Both the main radiator positioned immediately in front of the combustion chambers and the intercooler behind the low-pressure charger are supplied by a low-temperature water circuit with separate electric pump.

Detailed optimisation enables higher combustion pressure, increased output and enhanced efficiency.

The new torquey and high-revving diesel engine also breaks new ground with its specific output of 93.6 kW per litre of displacement. However, the output possible using M Performance TwinPower Turbo technology is generated not in the turbochargers but in the core of the basic engine, which has therefore also been extensively modified. Maximum combustion pressure has risen from the 185 bar of the most powerful diesel engine in the existing BMW line-up to 200 bar.

As part of this development, the crankcase in the new 3.0-litre diesel engine features an innovative tie rod concept for the assembly of the main bearing caps and cylinder head. The sintered main bearing caps are given extra strength by a central screw. Like the crankcase, the cylinder head is also subjected to a special high-pressure compression process. This "HIPen" manufacturing concept sees the aluminium castings heated to solution annealing temperature and the casting pores created during manufacturing welded under high pressure. This process gives the finished component additional strength. A double diagonal bore ensures the interbore bridges have high thermal stability.

The geometry of the crankshaft and connecting rods has been further optimised and they are now made from higher-strength materials. Added to which, hub bushings and bowl rim remelting enhance the effect of the increase in piston compression height.

Higher pressure also raises the efficiency of the injection system.

The injection system of the new six-cylinder in-line diesel engine has also benefited from a rigorous process of further development. The common-rail direct injection system plays its part in enhancing the engine's efficiency and promoting clean combustion by sending extremely precise quantities of fuel into the cylinders. The upgraded system raises the injection pressure of the piezo injectors to 2,200 bar. During each power stroke, three pre-injections, one main injection and four post-injections of fuel take place. An ultra-high-performance pump channels the fuel to the combustion chambers through a common rail made from forged stainless steel.

The output and capacity of the cooling system have been given another boost, too. An additional low-temperature circuit supplied by an electric water pump controls the temperature of the intercoolers. The exhaust treatment system includes a diesel particulate filter and oxidation catalytic converter, which is located close to the engine in the same casing. More efficient exhaust cooling, meanwhile, minimises the formation of nitrogen oxides. And standard-fitted BMW BluePerformance technology, which includes a NOX storage catalytic converter, helps the new diesel engine powering the BMW M550d xDrive to meet the EU6 exhaust standard not due to come into force until 2014.

Eight-speed Sports automatic transmission with M-specific gearshift dynamics.

The combination of the most powerful diesel engine ever offered for a BMW with an eight-speed Sports automatic transmission ensures that drive is transferred onto the road surface extremely effectively and efficiently. The configuration of the transmission management system for the BMW M Performance Automobiles promotes dynamic acceleration. The M-specification gearshift dynamics enable extremely rapid gear changes with an almost uninterrupted flow of power. The eight-speed Sports automatic transmission offers the driver two automated shift programs - D and S modes - as well as the option of changing gear manually (in M mode).

The automatic gearbox is operated using an electronic gearshift lever on the centre console adorned with an M logo. Manual mode allows the driver to change gears sequentially using either the gearshift lever or the paddles on the steering wheel. In customary M fashion, the right-hand paddle changes up a gear and the left-hand paddle is used for downshifts. If the driver activates manual mode using the gearshift lever, the transmission holds the gear selected until the engine's revs hit the limiter. By not shifting up automatically in this mode, the gearbox gives the driver maximum control over the car when pushing the dynamic boundaries. The driver can also switch instantaneously from automatic gear changes to M mode with a nudge of one of the gearshift paddles; if M mode is selected in this way, the gearbox's automatic shift-up function remains active. The transmission also restores automatic mode if the gearshift paddles are not used again following an upshift or downshift.

Enhancing the natural soundtrack inside the car turns driving pleasure up yet another notch.

The performance capability of the diesel engine and the hallmark M driving characteristics of the BMW M Performance Automobiles underpin a new definition of driving pleasure. Imposing torque and a set-up focused squarely on sports performance give drivers a dynamic driving experience they will never have previously sampled in a diesel car. The BMW M Performance Automobiles also lace this driving pleasure with additional acoustic appeal. Through sound design technology, the natural engine sound is specifically enhanced to suit the driving situation at the time and sent into the interior via the audio system, ensuring an authentic reproduction of the new engine's unmistakable straight-six soundtrack.

The system's digital signal processing technology exchanges data directly with the engine management, allowing it to base its precise transmission of the engine's timbre on the revs at any one time, the amount of torque being produced and the car's speed over the road. Accentuating the straight-six diesel's turbine-like, sporty and sonorous tones adds to the emotional appeal of the driving experience, especially in the BMW M550d xDrive when SPORT or SPORT+ mode is activated using the Driving Experience Control switch. This gives the driver an impressively accurate impression of how hard the engine is currently working and of the power being unleashed, and provides an even clearer window into the car's responses on the road. Controlling the audio system in this way also ensures that the engine sound can be enjoyed to equal effect from every seat.

The unit developed to power them fulfils its sporting brief with leading performance in a range of disciplines and, in so doing, dismantles the historic contradiction between driving pleasure and economy even more effortlessly than ever.

BMW M135i (2013)

BMW says the three-door 1 Series has "a more dynamic and elongated appearance" than its five-door sibling, pointing to details like its rising character line, frameless windows and "powerfully flared wheel arches" as unique elements. We won't argue any of that, but we're still not entirely sold on the new 1er's nostrils.

Underhood lies BMW's well-known Twin Power Turbo 3.0-liter inline six that sends "more than 300" horsepower to the rear wheels. The suspension has been modified for M Performance duty, and the wheels have been upgraded to 18-inch M-branded alloys. We expect something along these lines to show up in production guise in relatively short order... at the very least for European buyers.

Engines: the straight six-cylinder petrol engine with M Performance TwinPower Turbo for the BMW M135i tops the engine line.

This power plant enhances the wide selection of engines available for the new compact three-door BMW 1-Series. At the same time, it is an essential component of a portfolio that positions BMW M Performance automobiles at the top of the performance segment. The BMW M135i is powered by a straight six-cylinder engine with M Performance TwinPower Turbo technology, which is known for its spontaneous performance and high revving, plus a level of efficiency that is remarkable in this performance class. The technology package includes a TwinScroll turbocharger, direct High Precision Injection with central multi-hole injectors, VALVETRONIC variable valve control and Double VANOS variable camshaft timing. This 3.0-litre engine delivers a maximum power output of 235 kW/320 hp at 5 800 rpm. This impressive power results from the maximum torque of 450 Nm that is available between 1 300 and 4 500 rpm.

The BMW M135i sprints from 0 to 100 km/h in just 5.1 seconds (automatic: 4.9 seconds) and reaches a top speed of 250 km/h - the top limit permitted by the vehicle's electronic speed control system. Average fuel consumption in the EU test cycle is 8.0 litres (7.5 litres)/100 km, and the CO2 emissions level is 188 grams (175 grams) per kilometre. The exclusive power train for the compact BMW M Performance car also features a customised cooling system, M performance control and engine sound tuning, plus a newly developed six-speed manual transmission with dry sump lubrication. A dynamic eight-speed automatic sports transmission with gearshift paddles integrated in the steering wheel is available as an option.

The BMW M135i: maximum agility combined with unparalleled precision thanks to M-specific suspension tuning.

Model-specific suspension technology allows the BMW M135i to exploit the performance of its uncommonly powerful engine, allowing the driver to experience remarkably self-assured, exhilarating driving dynamics. Thanks to the individual control of the suspension and damping systems as well as the specific elasto-kinematics of the front axle, the BMW M Performance vehicle is able to indulge the driver with a set of particularly sporty driving characteristics. In addition, its Variable Sports Steering system determines its own set of characteristics. The harmonious interaction of engine, suspension and aerodynamic balance rewards with a fascinatingly agile driving experience, under the precise control of the driver at all times.

The BMW M Performance vehicle is delivered with a fixed calliper M Sport Brake System with four-piston units on the front axle and two-piston units at the rear as standard equipment. The system is fitted with oversized brake discs and dark blue metallic callipers bearing the M logo. The M Sport Brake System is also available on all of the other models in the new BMW 1-Series three-door sedan range, in combination with the optional M Sport Package.

The standard 18-inch M light alloy wheels on the BMW M 135i are fitted with tyres of differing sizes: 225/40 R18 on the front axle and 245/35 R18 on the back. The high grip tyres, designed specifically for this model, guarantee that both the acceleration torque and the braking torque are optimally transmitted to the road surface.

DSC Driving Stability Control with additional features, optimised weight and comprehensive passenger protection.

The standard Dynamic Stability Control system DSC includes the anti-lock braking system (ABS), the Dynamic Traction Control system (DTC), the Cornering Brake Control system (CBC) and the Dynamic Brake Control system (DBC). These capabilities are now complemented by additional features such as the Brake Assistant, Fading Compensation, Dry Braking functionality and a Hill Start Assistant. In DTC mode, the response thresholds of the driving stability control system are automatically set at a higher level. This makes pulling away on loose sand or in deep snow far easier. In addition, controlled slippage on the drive wheels gives the vehicle the ability to dynamically oversteer when negotiating bends. When DSC mode is off, the Active Differential Brake (ADB-Sport) on the rear axle is activated. To optimise traction during acceleration in tight bends, a carefully calculated braking force is applied to any drive wheel which the system detects as slipping, to enable the remaining drive wheel on the axle to continue to power the vehicle forwards.

The principle of intelligent lightweight design, upon which the construction of the body is based, greatly enhances both the agility of the vehicle and the safety of its passengers. The targeted use of high-strength and ultra-high tensile grades of steel increases the torsional stiffness of the body, as well as the strength of the passenger safety cell, at an optimised weight. With large, generously dimensioned deformation zones and precisely calculated load paths, the considerable forces which are generated in a collision are absorbed and directed away from the passenger compartment. Standard safety equipment includes front airbags, side airbags integrated into the seat backs, head airbags for both the front and the rear seats, three-point automatic seatbelts fitted to all seats, belt force limiters and belt tensioners for the front, and ISOFIX child seat 

BMW 750Li (2013)

2013 BMW 750Li has a fairly luxurious interior, with a distinctive interior features BMW’s persistent focus on the driver. ways in which they are interested in ergonomics for the person behind the wheel. In a series of new 750Li, this includes the addition of newly designed, slimmer front seats offer the best ergonomics, optimal lateral support and the end of the long-distance comfort. Multifunctional sport seats and chairs are also available in a standard item. The latter can be ordered with a folding table in the back or with a Rear Seat Entertainment package as an option.

2013 BMW 750Li has a new feature is 9.2 inch screen, rather than integrated into the front seat, seems to “float” on them. Their exclusive designs take inspiration from the latest generation of flat screen monitor, which gives them a view of the very small and lightweight. when you drive a 2013 BMW 750Li is a very comfortable atmosphere you will enjoy.

All-new headlights sharpen the presence of the BMW 7-Series

From the front, the long, broad bonnet of the BMW 7-Series gives it an elegant and expressive profile. The precise contour lines of the bonnet draw the eye to the upright new BMW kidney grille as they extend forward. The grille's chrome surround is now larger, a change which - together with a new slat arrangement (nine slats instead of 12) - gives it greater prominence and reinforces the car's presence on the road. With their elegant accent strip and hallmark BMW corona rings, the optional new full-LED headlights accentuate the unmistakable appearance of the BMW 7-Series.

The large, full-width air intake dominating the lower section of the modified front apron is now split into three sections, a pair of chrome bars marking its outer sections and adding further depth to the car's sporty looks. Two narrow vertical air intakes sit beyond even the LED foglamps to the left and right of the wide intake. These are included as part of the "air curtain" technology, which lowers fuel consumption at higher speeds by forcing the air to flow more aerodynamically around the front wheels. The design of the air curtain therefore represents a fine technological advertisement for the BMW EfficientDynamics strategy.

Hallmark BMW proportions, such as a long wheelbase, short front overhang, long, sweeping bonnet and set-back passenger compartment with a coupe-like roofline, define the sporting and elegant silhouette of the BMW 7-Series. A new design feature that stands out from the side is the indicator integrated into the lower section of each exterior mirror, which makes the car easier to see and therefore safer to drive.

The powerful rear of the BMW 7-Series exudes a feeling of sporting assurance. The horizontal lines and subdivision of the rear into several levels visually lowers the height of the car. The design of the brand's familiar L-shaped rear lights, linked by an eye-catching chrome strip, remains unchanged. They are, however, richer in contrast thanks to differing shades of red. A second, delicately sculpted chrome strip draws a visual connection between the two slim reflectors in the rear apron and gives the rear view a more exclusive and solid feel overall. Another slim chrome bar between the four chromed tailpipe embellishers in the rear apron is a distinguishing feature of the 12-cylinder flagship model.

Exclusive design for the new Rear Seat Entertainment package

The picture of stylish exclusivity and luxurious character is painted with equal clarity inside the new 7-Series. The interior possesses an undeniable air of quality and harmoniousness. Smoothly flowing forms, exquisite materials and stylish colour combinations determine the car's luxurious overall impression. Dakota leather and Nappa leather can now be ordered in Ivory White with the world colour Black and Veneto Beige with the world colour Veneto Beige. The outstanding build quality of the BMW 7-Series reflects the attention to detail of the car's creators, and evidence of the precise craftsmanship at work is striking.

A typical feature of BMW interiors is their unflinching focus on the driver - the way in which they gravitate ergonomically towards the person behind the wheel. In the new 7-Series, this includes the addition of newly designed, more slender front seats offering the best possible ergonomics, optimum lateral support and ultimate long-distance comfort. Sports seats and multifunction seats are also available in place of the standard items. The latter can be ordered with a folding table in the backrest or with the Rear Seat Entertainment package as an option. A brand-new feature are the 9.2-inch screens which, instead of being integrated into the front seats, appear to be "floating" on them. Their exclusive design takes its inspiration from the latest breed of flatscreen monitors, which gives them an extremely slight and lightweight look.

The new BMW 7-Series can be specified as an option with individual rear seats that can be adjusted to suit individual requirements. The backrest angle and seat position can both be varied, as can the position of the head restraints. The controls are the same as those for the front seats with memory function.

The long-wheelbase version of the BMW 7-Series provides the ideal platform on which to maximise long-distance comfort. All of the 140 millimetres added to the wheelbase of the standard-length 7-Series are used to lay on a calm and relaxed journey for the rear passengers in a first-class environment. Indeed, changes to the roofline of the long-wheelbase version create 10 millimetres of extra headroom in the rear.

Extending centre speaker adds to the audio experience

The optimum interior soundproofing of the BMW 7-Series takes the on-board experience another step towards perfection. Additional insulation materials in the B and C-pillars, skirts and boot area team up with intricate sealing around the window frames and exterior mirrors to minimise driving noise. All of which brings the sound experience generated by the new Bang & Olufsen High End Surround Sound System even more powerfully to the fore. The 1,200-watt music system is hooked up to 16 speakers, some of which are positioned behind illuminated, satin-finish aluminium grilles sited in the mirror triangles of the doors and the parcel shelf. The most attention-seizing member of the speaker line-up is the illuminated centre speaker which extends out of the instrument panel and uses B&O Acoustic Lens Technology. Its distinctive form guarantees perfect sound quality in every seat. When the music system is switched off, the centre speaker retreats back into the instrument panel almost without trace. Meanwhile, the new ambient lighting for the interior creates a pleasant ambience, especially at night. Footwell lights for the driver and front passenger and indirect roof liner illumination via lights integrated into the B-pillars further enhance the feeling of well-being. The colour of the ambient light can be altered according to taste.

New screen experience: the multifunctional instrument display

A particular highlight of the BMW 7-Series is the multifunctional instrument display, which makes its debut appearance on the options list. In place of the traditional instrument cluster - in which four circular analogue dials keep the driver informed of the car's speed, engine revs, fuel level and oil temperature -an almost seamlessly integrated 10.25-inch display provides a totally new and appealing screen experience consciously inspired by the looks of the latest electronic devices.

While the familiar format of four circular instruments is retained here, the extended black-panel technology hands the driver a whole new set of display options. For example, the display shows varying information and different colour and mood worlds in the COMFORT, SPORT and ECO PRO driving experience modes, ensuring greater safety and efficiency and demonstrating an exemplary focus on the driver. The information shown is tailored to the driving mode currently engaged and therefore changes accordingly. All of which means the display the driver sees in the instrument cluster is always the optimum one for the driving situation at hand.

While COMFORT mode brings a classic layout with four solid circular instruments, in ECO PRO and SPORT modes the rings open to offer additional space for extra information between the two instruments. In ECO PRO mode the display turns blue in colour and the rev counter morphs into an Efficient Dynamics display to show how efficiently the car is being driven. Here drivers can monitor how hard they have their foot on the accelerator, how much fuel the car is currently using and whether any energy is being recovered through recuperation. If they are pressing too forcefully on the accelerator, the full display turns grey and alerts them to the amount of fuel they are burning unnecessarily. A speedometer zoom function can also be activated in ECO PRO and COMFORT modes. This enlarges the position of the speedo needle as if a magnifying glass were being passed over it, making it even easier to see.

In SPORT mode the display takes on a signature BMW orange hue. This display mode purposefully retains a very puristic look and only shows the driver the most essential information, so that he can maintain maximum concentration on the road ahead. The speedometer shows the car's speed in digital form only with a large, centrally positioned figure, while the gear currently engaged is boldly displayed in the middle of the rev counter if the driver is shifting manually using the steering wheel paddles. As well as the changes in colour, the displays in the instrument cluster also deliver additional information tailored to the situation at hand - such as status and function updates, Check/Control messages and navigation instructions - which drivers can call up as and when they wish.

Control Display

The introduction of the new multifunctional instrument display is accompanied by a technical and stylistic update for the central Control Display positioned between the driver and front passenger. A black surround lends the recessed 10.25-inch display additional visual depth, which has the effect of making it look even larger. Vertical electroplated bars border the screen to the sides and add extra visual flourishes which the electroplated surrounds for the cupholder lids carry over into the centre console.

Powertrain and chassis: Even more ways to enjoy refined power delivery, enhanced efficiency and a step up in comfort

The new BMW 7-Series is poised to strengthen its position even further as the most innovative sedan in the luxury segment. New and comprehensively revised engine variants set new standards in terms of performance and efficiency. All the engines available for the new 7-Series team up with an intelligent eight-speed automatic transmission and distinguish themselves with significantly reduced fuel consumption and emissions. The Auto Start-Stop function, Brake Energy Regeneration and the second-generation Driving Experience Control switch with ECO PRO mode offer additional potential for fuel-saving. Carefully optimised suspension and Electric Power Steering for all rear-wheel-drive models also take driving comfort to a new level, while self-levelling air suspension for the rear axle likewise comes as standard on all models.

Alongside the flagship BMW 760i with 12-cylinder powerplant and the entry-level engine in the BMW 730i (not available in all markets), customers can choose from the new six-cylinder in-line unit powering the BMW 740i and the revised V8 petrol engine in the BMW 750i. The six-cylinder diesel engines in the BMW 730d and BMW 740d also offer drivers the combination of increased output and lower fuel consumption. Making its debut, meanwhile, is the new BMW 750d xDrive. Under its bonnet lies the new TwinPower Turbo six-cylinder diesel engine - the world's most powerful diesel engine of its kind. Rounding off the range is the second-generation BMW ActiveHybrid 7 with new six-cylinder in-line engine and significantly reduced emissions.

BMW 760i: refined 12-cylinder engine still top of the tree

The V12 engine with BMW TwinPower Turbo technology, direct petrol injection and continuously variable camshaft control represents the pinnacle of the BMW 7-Series engine range - no change there. The all-aluminium powerplant generates output of 400 kW/544 hp from its 5,972 cc displacement and makes peak torque of 750 Newton metres (553 lb-ft) available as low down as 1,500 rpm. That's enough to propel the BMW 760i effortlessly from 0 to 100 km/h (62 mph) in just 4.6 seconds and on to an electronically limited top speed of 250 km/h (155 mph). With average fuel economy of 12.8 litres per 100 kilometres (22.1 mpg) and CO2 emissions of 299 g/km, this most cultured of power merchants achieves unprecedented efficiency for its output class.

BMW 750i: eight-cylinder engine develops more power but burns less fuel

The revised V8 petrol engine under the bonnet of the BMW 750i is making its debut. The 4,395 cc eight-cylinder powerplant retains the impressively smooth assurance and spirited power delivery of its pre-update days. However, optimised high-pressure direct injection and reduced charge cycle losses - thanks in the main to the seamlessly variable control of intake valve lift - have pushed its performance potential to a higher level than its predecessor and substantially reduced its fuel economy and emissions. In its latest development stage, the engine generates peak output of 330 kW/450 hp (+ 10 %) and unleashes peak torque of 650 Newton metres / 479 lb-ft (+ 8.5 %) between 2,000 and 4,500 rpm. The engine teams up with the eight-speed automatic transmission, allowing the BMW 750i to sprint from 0 to 100 km/h (62 mph) in just 4.8 seconds and progress on to an electronically governed top speed of 250 km/h (155 mph). The eight-cylinder engine belies its improved performance with better efficiency than ever; with overall fuel consumption of 8.6 litres per 100 kilometres (32.9 mpg) and CO2 emissions recorded at 199 g/km, the BMW 750i trumps its less powerful predecessor by a clear 25 per cent. In the Chinese market, the BMW 750i is powered by a 4-litre variant of the engine offering 300 kW/408 hp and 600 Newton metres (443 lb-ft) of torque.

BMW 740i: new six-cylinder petrol engine boasts outstanding efficiency

The 3-litre six-cylinder in-line engine stands out with its majestic power and unparalleled high-revving character. The state-of-the-art powerplant is one of the first wave of highly efficient petrol engines to bring together BMW TwinPower Turbo technology with High Precision Direct Petrol Injection, twin-scroll turbocharging, Double-Vanos variable camshaft timing and Valvetronic variable valve timing. Peak output of 235 kW/320 hp and a maximum 450 Newton metres (332 lb-ft) of torque on tap as low down as 1,300 rpm make this ultra-refined engine the performance equal of the outgoing BMW 740i. However, fuel economy in the EU test cycle is an impressive 7.9 litres per 100 kilometres (35.8 mpg) while CO2 emissions of 184 grams per kilometre represent a 21 per cent reduction in its predecessor's output.

BMW 730i: entry-level engine variant with reduced fuel consumption (not available in all markets)

This proven 3-litre straight-six petrol engine develops, as before, 190 kW/258 hp and maximum torque of 310 Newton metres (229 lb-ft) at 2,600 rpm. Linking up with the new eight-speed automatic transmission allows the BMW 730i to exploit additional fuel-saving potential; average fuel economy stands at 8.6 litres per 100 km (32.9 mpg), while CO2 emissions of 199 grams per kilometres are 13 per cent below the level recorded by its predecessor working with a six-speed transmission.

BMW 750d xDrive: new range-topping TwinPower Turbo six-cylinder diesel engine with intelligent all-wheel drive

The brand-new top-of-the-line diesel powerplant under the bonnet of the BMW 750d xDrive provides fresh evidence of BMW's pre-eminence in the area of engine technology. The world's most powerful six-cylinder in-line diesel engine grabs the headlines with its innovative and unique technology, and imbues the luxury sedan with impressive dynamics and outstanding efficiency.

The remarkable TwinPower Turbo technology at the heart of the six-cylinder unit works with three turbochargers and a further developed common rail injection system for the first time in order to optimise the engine's output, torque and responsiveness. The precisely coordinated management of the turbochargers ensures that the 3-litre high-performance diesel engine develops imposing pulling power across the full rev range - and all with an exceptionally high level of efficiency. The first charger starts work at just over idle so the combustion chambers can be supplied at an early stage. At 1,500 rpm a larger high-pressure turbo kicks in to help the engine reach its maximum torque. Finally, the third turbocharger joins the fray at 2,700 rpm and ensures particularly impressive power delivery until maximum revs are reached. Piezo injectors spray the fuel into the combustion chambers at up to 2,200 bar, with three pre-injections, one main injection and four post-injections of fuel during each power stroke ensuring efficient and clean combustion.

This enviable engine technology enables the six-cylinder in-line powerplant to produce maximum output of 280 kW/381 hp and impressive peak torque of 740 Newton metres (546 lb-ft) from as low down as 2,000 rpm, endowing the BMW 750d xDrive with extraordinary thrust. Indeed, the Sedan races from 0 to 100 km/h (62 mph) in only 4.9 seconds. The engine's vast reserves of power also give it a compelling elasticity. Equally impressive as its performance capability, however, are the efficiency benefits of the BMW diesel technology on board; the Sedan posts fuel economy of 6.4 litres per 100 kilometres (44.1 mpg) in the EU test cycle, which means CO2 emissions are also suitably low at 169 g/km. Plus, BMW BluePerformance technology enables the new flagship diesel to meet the EU6 exhaust gas standard comfortably ahead of time.

The permanent, electronically controlled all-wheel drive of the BMW 750i xDrive ensures the power from this range-topping diesel finds its way safely onto the road at all times by dividing engine power between the front and rear wheels in response to the situation at hand. The system's precision and rapid responses help give the Sedan stable and dynamic driving characteristics even under demanding conditions.

BMW 740d: further reduction in fuel consumption and emissions

The rigorous further development of BMW TwinPower Turbo technology has also given the dynamics and efficiency of the familiar six-cylinder in-line diesel engine a boost. At 230 kW/313 hp, the maximum output of the 3-litre six-cylinder diesel is five kilowatts higher than its predecessor's, while peak torque of 630 Newton metres / 465 lb-ft (+ 30 Nm / 22 lb-ft) comes on stream at 1,500 rpm. Added to which, thermodynamic optimisations sharpen the diesel model's responses and enhance its agility. Linking up with the new eight-speed automatic transmission, the more powerful BMW 740d manages to record even lower fuel consumption of 5.7 litres per 100 kilometres (49.6 mpg) to go with CO2 emissions of 149 g/km. That's a 17 per cent improvement on its predecessor.

BMW 730d: cleanest diesel in the luxury segment, emitting just 148 g/km

Another round of fuel consumption and emissions reductions sees the BMW 730d building on its position as the world's most economical luxury sedan with the lowest emissions. Peak output of the 3-litre six-cylinder diesel engine, whose construction mirrors that of the engine in the BMW 740d, has increased by 10 kilowatts to 190 kW/258 hp. And its maximum torque has also risen to 560 Newton metres / 413 lb-ft (+ 20 Nm / 15 lb-ft). However, average fuel economy of 5.6 litres per 100 kilometres (50.4 mpg) in the EU test cycle and CO2 emissions of just 148 g/km allow it to outperform its predecessor - married to a six-speed automatic transmission - by 17 per cent. Specifying the engine with the optionally available BluePerformance technology equips it to meet the EU6 standard.

BMW xDrive: available as an option for the BMW 750i, BMW 740d and BMW 730d

BMW xDrive intelligent all-wheel drive makes the BMW 7-Series Sedan an even more attractive proposition. In addition to the typical benefits of all-wheel drive, the electronically controlled xDrive system - which can vary the power distribution between the front and rear wheels with split-second speed - ensures top-class traction, safety and handling, and optimal power management whatever the weather and road conditions. The system has been set up to deliver greater agility and precision through corners as well, offers an ideal combination of dynamism and comfort, and provides the perfect basis for a refined driving experience.

BMW ActiveHybrid 7: second generation with six-cylinder petrol engine

As BMW continues to push ahead with the development of intelligent hybrid drive systems, the second generation of the BMW ActiveHybrid 7 is set to celebrate its premiere in 2012. The updated model sets itself apart with lower fuel consumption and emissions, as well as innovative auxiliary functions. This latest evolution stage uses a six-cylinder in-line engine displaying impressive high-revving characteristics, torque and efficiency. The cutting-edge petrol engine with BMW TwinPower Turbo technology is the 235 kW/320 hp variant of the unit fitted in the new BMW 740i and replaces the eight-cylinder engine used up to now. Other hybrid components include the 40 kW/55 hp synchronous electric motor, the hybrid-spec eight-speed automatic transmission, a lithium-ion high-performance battery and power electronics underpinning intelligent energy management. The various components come together into a powerful and harmonious whole, giving the new BMW ActiveHybrid 7 exceptional dynamics and an outstanding balance between performance and fuel economy - and not only in relation to its predecessor.

With system output of 260 kW/354 hp and peak torque of 500 Newton metres (369 lb-ft), the new BMW ActiveHybrid 7 accelerates from 0 to 100 km/h (62 mph) in just 5.7 seconds. At the same time, the Sedan posts average fuel economy of 6.8 litres per 100 kilometres (41.5 mpg) and CO2 emissions of 158 g/km. That means the more powerful hybrid technology uses some 14 per cent less fuel than a BMW 740i with a conventional drive system.

A host of innovative functions are involved in enhancing the car's dynamics and achieving the excellent efficiency of the overall system. For example, the electric motor hands the six-cylinder an extra 210 Newton metres (155 lb-ft) of torque through the boost function, should the driver need to nail a quick sprint or call on some hard mid-range acceleration. In addition, Brake Energy Regeneration, the Hybrid Start Stop function, ECO PRO mode with coasting function and proactive analysis - to prepare the car's drive system in advance for upcoming situations on the road - ensure the available energy is used as efficiently as possible (more details in the "BMW EfficientDynamics" chapter). The new BMW ActiveHybrid 7 can also run purely on electric power. If the hybrid battery has sufficient charge and the driver goes easy on the accelerator, the car can cover a distance of up to four kilometres (just under 2.5 miles) almost silently and without producing any tailpipe emissions. The top speed possible using electric power alone is 60 km/h (37 mph).

Innovative eight-speed automatic gearbox now fitted as standard

For the year 2012 BMW is fitting all 7-Series models with the extremely effective eight-speed automatic transmission previously reserved for the BMW 760i, BMW 740d xDrive and BMW ActiveHybrid 7. Its additional ratios allow the gearbox to combine unbeatable shift comfort and efficiency, while at the same time aiding the dynamic qualities of the BMW 7-Series Sedan. With its intelligent control technology, the eight-speed transmission boasts extremely fast shift and reaction times and direct downshift capability. The electronic transmission controller can also alter the shift characteristics as required, to cater either for a more sporty or for a more relaxed, fuel-saving driving style.

Despite a larger overall spread, eight ratios mean that the spacing between them is smaller, so that the optimal ratio is available in virtually all situations. The close ratios deliver refined and powerful acceleration as well as smooth and fuel-efficient low-rpm operation. Altogether, then, as well as providing dynamic acceleration and smooth shifting, the new eight-speed automatic also allows drivers to maintain a very economical driving style.

The chassis: optimised set-up and extended standard specification noticeably enhance comfort levels for the driver and passengers

Dynamic performance, ride comfort and active safety are again among the stand-out qualities of the BMW 7-Series Sedan in the year 2012. Sophisticated chassis technology plays a key role here, providing the ideal partner for the refinement and power of the drive systems. A host of measures give the ride comfort of the Sedan a noticeable boost. Complementing the optimised chassis set-up - with modified rubber bearings and new dampers - and the self-levelling air suspension for the rear axle, Electric Power Steering is a standard feature of the models with rear-wheel drive. State-of-the-art electronic control systems with likewise retuned software help to enhance the long-distance attributes of the BMW 7-Series Sedan and ensure that the new edition of the car makes travelling on board even more pleasurable in terms of both dynamics and comfort.

Dynamics made even more comfortable: double-wishbone front axle and integral-V rear axle with self-levelling air suspension

The front axle of the BMW 7-Series Sedan is based on the familiar aluminium double-wishbone construction combining maximum rigidity and minimised weight. The patent-protected integral-V rear axle of the BMW 7-Series Sedan is also made from aluminium. The use of modified ball joints, stiffer hydraulic dampers, new rubber bearings and carefully tuned elastokinematics has allowed the engineers to minimise vibrations and therefore bring about a perceptible improvement in onboard comfort levels. By effectively cutting the link between the road surfaces and the drive system, the rear axle also allows the driver and passengers to enjoy excellent acoustic comfort and impressively low vibrations.

All BMW 7-Series models are now kitted out with high-comfort rear axle air suspension, which keeps the car riding at a constant height no matter what kind of driving conditions it encounters and regardless of the loads you have on board. This automatic self-levelling suspension responds to any change in load by adjusting the suspension at the relevant wheel. This means that only small interventions are required in response to spring movements caused by road imperfections and cornering tilt.

Always on the safe side: the lightweight braking system and advanced electronic control systems

The compound braking system with lightweight, inner-vented swing-calliper disc brakes provides outstanding deceleration in any situation and brakes the Sedan to a standstill in a very short space of time, even from high speeds. In so doing, the system also offers extremely high resistance to fade as well as unbeatable braking comfort. The braking system is backed up by various state-of-the-art electronic safety systems which are integrated into the Dynamic Stability Control (DSC) package and assist the dynamic performance and active safety of the luxury sedan to equal effect. DSC incorporates the Anti-lock Braking System (ABS), Automatic Stability Control (ASC), Dynamic Traction Control (DTC), Dynamic Brake Control (DBC) and Cornering Brake Control (CBC), along with Start-Off Assistant, brake drying and an electronic limited slip function for the rear differential, which can be activated using the "DSC Off" button.

Dynamics and ride comfort to suit the occasion: Dynamic Damper Control, Dynamic Drive and the Driving Experience Control switch with ECO PRO mode

The BMW 7-Series is the world's first car to come with an electronically controlled damping system whose dampers are adjusted at each wheel individually according to the condition of the road surface and driving style. The compression and rebound settings are adjusted continuously and independently from one another. For example, a stiff chassis setting can be combined with comfortable responses to unevenness in the road surface. The damper settings can be pre-set by the driver using the Driving Experience Control switch. Optimised software tuning improves ride comfort while also giving agility an extra boost.

The Dynamic Drive roll stabilisation system available for the BMW 7-Series reduces, among other things, body roll in high-speed corners and under sudden changes in direction. Sensors calculate the amount of body roll and this is then counteracted quickly and precisely by rotary actuators in the front and rear axle stabilisers. The Sedan's steering behaviour and load alteration effect are also adjusted as required in this way. This system allows drivers to thread the car through corners with even greater agility and precision.

Driving Experience Control switch with ECO PRO mode and extended functions: extra sporty, comfortable or economical at the touch of a button

The new BMW 7-Series not only sets a new dynamic benchmark for luxury cars, it also raises the bar in the class when it comes to ride comfort. The driver can alter the overall character of the Sedan towards greater sportiness or comfort using the Driving Experience Control switch with ECO PRO mode. The distinction between the different driving modes is now even more pronounced. The Driving Experience Control switch with ECO PRO mode is part of the standard specification for all models, with the exception of the BMW 760i.

Using the Driving Experience Control switch, the driver is able to customise accelerator response characteristics, engine response, power steering characteristics and the Dynamic Stability Control (DSC) thresholds. Added to which, the Servotronic function, Integral Active Steering, the automatic transmission and Dynamic Damper Control are integrated into the system too. Using the simple-to-operate rocker switch on the centre console, drivers can choose between ECO PRO, COMFORT, SPORT and SPORT+ modes. Each of these predefined set-ups activates different settings for the relevant powertrain and chassis components. The clear ground between the various modes means the differences between them are now more easily perceptible. If the Integral Active Steering option has been specified, COMFORT+ mode is also available. This mode gains rear passengers, in particular, another noticeable increase in ride comfort.

Another button allows the driver to change the DSC settings. Selecting TRACTION mode, for example, makes it much easier to pull away on loose surfaces or in deep snow. In this mode, as well as in SPORT+, the Dynamic Stability Control thresholds are raised and Dynamic Traction Control (DTC) is activated. It is also possible to switch off DSC altogether.

The new ECO PRO mode, meanwhile, helps the BMW 7-Series driver to maintain an extra-efficient and economy-conscious driving style. It does this by changing the accelerator mapping so that the same pedal travel delivers less power than in the standard mode. Also in this mode, the transmission control strategy for the automatic gearbox is modified to bring forward upshifts and delay downshifts, while intelligent energy and climate management reduces mechanical power consumption and also the energy consumption of electrical systems such as heated mirrors and seats.

But the biggest factor influencing fuel consumption figures is the driver's own personal driving habits. That is why electronic systems provide tips and incentives on how to develop a more economy-conscious driving style for the situation at hand. Special displays in the instrument cluster let the driver know by how much the driving range is being extended and indicate his fuel consumption history. In ECO PRO mode, average fuel consumption can be reduced by up to 20 per cent, with a corresponding increase in driving range. Extended functions include the new coasting mode (with ECO PRO selected), plus proactive analysis of the driving situation and the subsequent advance preparation of the drive components (in the BMW ActiveHybrid 7). Both functions offer additional potential for fuel saving and are described in greater detail in the "BMW EfficientDynamics" chapter.
