The BMW M135i will be powered by a straight 6-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 will sprint 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.
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 will be 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.
