DSG - Direct Shift Gearbox
The DSG dual-clutch gearbox, available in 6-speed and 7-speed versions, is unlike a conventional automatic transmission. Two independent gearboxes are connected under load to the engine in turn, depending on the current gear, via two drive shafts.
An output shaft assigned to each gearbox applies the torque to the driven wheels via the differential gear. Clutches and gearboxes are operated hydraulically by the gearbox mechatronics (a combination of mechanics and electronics).
The electronic transmission control unit, sensors and hydraulic control unit form one compact unit. The control unit uses information such as engine speed, road speed, accelerator position and driving mode to select the optimum gear and to determine the ideal shift point.
The control unit then implements the shift commands in a sequence of precisely co-ordinated actions. Each change takes less than four-hundredths of a second. DSG can be used manually, via the Tiptronic gearlever or the optional paddle shifts.
XDS - Advanced electronic differential lock
XDS is an advanced electronic differential lock, linked to a sophisticated Electronic Stabilisation Programme (ESP) system.
We designed it to maximise road holding and improve responses, especially when cornering. In moments of fast cornering XDS gives out exactly the right amount of power, providing pressure on the inside wheel to prevent wheel spinning.
The result is better traction and a reduction of any tendency to under steer. You'll experience a more agile, precise and calm driving performance with better traction out of bends. In other words, you can enjoy sporty driving in your Volkswagen, knowing you have a reassuringly higher level of safety.
