Volkswagen has just released a new transmission system called DSG (direct select gearbox) with 7 speed, the latest generation of DSG clutch that is lighter, smaller, and more efficient compared the former DSG gearbox
The automatic gearbox that also can be shifted up or shifted down manually is called DQ200, using a dry double clutch that require less cooling system or even none. It's totally different from the predecessor (DSG 6 speed) that uses a wet double clutch that definitely need a cooling system and has more weight than the newly DSG 7 speed.
The newly DSG system also requires less power on shifting process, and servo clutch, hence will raise the fuel efficiency and engine performance. The double clutch also prevent engine rpm dropped on shifting process, so it will accelerate faster compared with a manual transmission car.
This transmission system is cross attached inside the car compactly, with 7 kgs lighter than a conventional 6 speed transmission.
The first VW car to use DQ200 is Golf GT 1.4 TSI twincharger and Golf GT 1.9 TDI Diesel
