BMW Z4: High Precision Injection and Twin Turbo

Driving pleasure. Optimally transmitted.

The eight-speed sport automatic transmission Steptronic in the BMW Z4 sDrive20i und sDrive28i.

Only the rev counter will reveal how quickly and comfortably the new eight-speed sport automatic transmission Steptronic in the BMW Z4 sDrive20i and sDrive28i changes gear. The additional gears reduce the rev interval of the engine between shifts making them barely perceptible. At high speeds the eighth gear reduces revs to increase comfort and lower fuel consumption. The system is also supported by the newly developed converter clutch – even if you use the electronic gearshift lever or the paddle switches on the steering wheel to change manually.
