S tronic®

Already in 1985, Audi tested the technology of the dual-clutch transmission in the Sport quattro S1 and was enthusiastic. Enthusiasm that Audi drivers can understand. Because the 6-speed S tronic changes the gears in less than 0.2 seconds. For this purpose, it integrates two multi-plate clutches that operate different gears. A large clutch transmits the torque via a solid shaft to the gears of the odd gears. A compact second clutch supplies the straight gears via a hollow shaft. The two partial transmissions are permanently active, but only one is permanently connected to the engine. For example, if the vehicle accelerates in third gear, only the first partial transmission transmits the power. In the second partial transmission, however, the fourth gear is already engaged. When switching then not only the gear changes, but equal to the clutch - and that in a few hundredths of a second. So fast and flowing that the driver hardly perceives him.
