Steptronic transmission.
The 6-speed or 8-speed Steptronic transmission sets new benchmarks in comfort and dynamic performance and is a key element of BMW EfficientDynamics.
The particularly fine increments between gears facilitate optimum power delivery at all speeds. This reduces fuel consumption significantly, while allowing the driver to enjoy increased sportiness and dynamic performance. At high speeds in particular, the additional gears reduce engine speed, in turn decreasing both fuel consumption and engine noise.
The converter clutch also helps – even if the car is in manual mode. In combination with the fast engine speed transitions and the precise transmission tuning, it provides a very high level of shifting comfort and reduces noise considerably.
Thanks to the 8-speed Steptronic transmission from BMW EfficientDynamics, it is now possible to actively boost performance in vehicles with the new Predictive Drive Train via the Driving Experience Control. In Sport mode, the transmission control uses data from the navigation system (required) to deliver even greater dynamic responsiveness based on route characteristics. As suggested by its name, Comfort mode offers a comfort-oriented shift programme with fewer shifts.
The 8-speed Steptronic Sport transmission makes changing gears exceptionally pleasant thanks to fast engine speed transitions and shorter shift times. It adapts to suit individual driving styles. It is perfect for everything from comfortable cruising through to a very dynamic drive. In addition to automatic gear selection, it is of course possible to shift gears manually at any time. This is done using the gear lever, or the gearshift paddles on the Sport leather steering wheel or M leather steering wheel.
In Sport mode, the gear shifts are configured for maximum performance. Acceleration is optimised due to very finely tuned gradation of the eight gears. What is more, the engine is continually optimised to guarantee the best possible performance and driving characteristics. Maximum acceleration from a standing start is made possible by Launch Control: this feature shifts automatically in order to make use of the engine's optimum rpm range. Additional sport-oriented shift programmes guarantee an exceptionally dynamic driving experience, with shorter shift and reaction times and the capacity for multiple downshifts.
When travelling at high speeds, the eighth gear reduces engine speed and fuel consumption, as well as engine noise. This is also where the newly developed converter clutch comes into play. The 8-speed Steptronic Sport transmission delivers outstanding performance, efficiency and convenience when changing gears.
