Page 1 of 1 From 2003, Audi's TT Coupe is available with a V6 engine. The V6 is the familiar 15 degree 3.2 litre unit already found in many other VAG models. In the TT Coupe however, it is found in its most powerful shape, pumping out a decent 250 bhp.
With 250 horses on the tap, its essential to maintain traction at all times. So it comes as no surprise that the top-of-the-line TT is equipped with Audi's Quattro all wheel drive system. The connection between the engine and the Quattro system is formed by an all new 6-speed gearbox.
The revolutionary Direct-Shift Gearbox combines the advantages of a conventional 6-speed manual gearbox with the qualities of a modern automatic transmission. The driver thus benefits from enormous agility and driving enjoyment with acceleration that is as harmonious as it is dynamic, without any interruption in the power flow. This is combined with good economy thanks to low fuel consumption, and convenient operation. The basis for this new development is a three-shaft 6-speed manual gearbox which offers considerable variability in the selection of the transmission ratio. Thanks to the use of a twin multi-plate clutch with ingenious electro-hydraulic control, two gears can be engaged at the same time. During dynamic operation of the car, one gear is engaged. When the next gearshift point is approached, the appropriate gear is preselected, but its clutch kept disengaged. The gearshift process opens the clutch of the activated gear and closes the other clutch at the same time with a certain overlap. The gear change takes place under load, with the result that a permanent flow of power is maintained. The control logic integrated into the transmission casing maintains optimum gearshift strategies that perform lightning-fast gearshifts that are nevertheless smooth and almost jolt-free. The driver can directly influence the gear selected and the gearshift timing at will, by means of the gear lever in the manual gate or, in the style of a racing driver, using the standard-fit shift paddles on the steering wheel.
