8-speed Steptronic transmission.
The 8-speed Steptronic transmission sets new benchmarks in comfort and dynamic performance and efficiency and is a key element of BMW EfficientDynamics.
The unusually 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 changed to the manual mode. In combination with the fast engine speed transitions and the precise transmission tuning, it provides a very high level of shift 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 the "Sport" mode, the transmission management uses data from the navigation system to deliver a level of responsiveness that is even more dynamic and spontaneous based on route characteristics. As suggested by its name, the "Comfort" mode offers a comfort-oriented shift programme with fewer shifts.
