8-speed Steptronic transmission.
The 8-speed Steptronic transmission sets a new benchmark in dynamic performance and efficiency and is a key element of BMW EfficientDynamics.
The particularly finely tuned gradation of the gears allows optimum power delivery – at both low and high 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.
