The 8-speed Steptronic transmission sets a new benchmark in terms of dynamic performance and efficiency and is a key element of BMW Efficient-Dynamics. The particularly finely tuned gradation of the gears allows optimum power delivery – from low through to high speeds. This reduces fuel consumption significantly, while enabling the driver to enjoy even more sporty flair and dynamic performance. At high speeds in particular, the additional gears reduce engine speed and therefore both fuel consumption and engine noise.
The converter clutch is a contributing factor here – even if it is changed into manual shift 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.
