The seven-speed sport automatic double-clutch transmission in the BMW Z4 Roadster.
Taking your breath away but not your speed, the seven-speed sport automatic transmission* transfers engine power to the road without the slightest disruption to tractive force. With two transmission structures the system is able to switch simply between the two, thus providing constant power to the rear wheels. Gears can be changed without the transmission of power being interrupted using either the paddles on the steering wheel, the shift lever or the automatic mode for even more dynamic comfort. The Driving Dynamic Control is used to effortlessly switch between the Normal, Sport und Sport+ options.
*Only available for the BMW Z4 sDrive35i.
