    The Volkswagen's Dual-clutch Transmission is called Direct Shift Gearbox (DSG).

    Here is the function of DSG which I found in the Golf GTI catalog:

    DSG is a manual gearbox in which the gearshifts are controlled

    electronically. What makes the DSG unique is that it has 2

    separate gear sets operated by 2 wet multi-plate clutches. The

    benefit of 2 gear sets and 2 multi-plate wet clutches is that one

    gear set and clutch is engaged driving the vehicle with the

    second clutch having already pre-selected the next gear

    awaiting for power to be transferred. As the next gear has already

    been pre-selected prior to power being applied, the gear change

    only takes 3–4 100ths of a second. There is virtually no

    interruption to power, traction or acceleration.
