Another feature that differentiates the TT from its competitors is the standard all wheel drive system. This system, called the "quattro" system by Audi, is held over from the last model. Audi has been perfecting the system since the early 1980's, and the system helps the car have superior grip and road-holding capabilities. All of this power is delivered through a 6 speed "Tiptronic" transmission. This transmission was first employed by Porsche in its vehicles, and allows the driver to switch between manual or automatic modes when driving.
