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
