Direct-Shift Gearbox

At the turn of the century, Volkswagen introduced the Direct-Shift Gearbox (DSG), an automated manual transmission, drivable like a conventional automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electrohydraulically controlled clutches instead of a torque converter. This is implemented in some VW Golfs, Audi A3 and TT models where DSG is called S-tronic.
