The eight-speed Steptronic automatic transmission in the BMW 5 Series Gran Turismo.
The rev counter is the only place you'll notice: with the new eight-speed Steptronic automatic transmission, the smaller increments between gears increase the BMW 5 Series Gran Turismo’s ride and shift comfort. They also enable faster gearshifts and more flexible use of the optimum rev range. This reduces fuel consumption and lowers CO2 emissions. Even when shifting manually the electronic gearshift lever is supported by the newly developed converter clutch, providing a more exhilarating drive.
