8-speed Steptronic transmission.
The 8-speed Steptronic transmission sets a new benchmark in terms of dynamic performance and efficiency and is a key element of BMW EfficientDynamics.
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 you to enjoy increased 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 you change 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.
