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 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.
