<FONT size=2>Direct Shift Gearbox (DSG)
Audi's revolutionary Direct Shift Gearbox combines the benefits of a six-speed manual transmission with the qualities of a modern automatic version. With roots in motor racing, this one of a kind twin-clutch allows one gear to be pre-selected while another is engaged. When the gear shift point is achieved, the gear change takes place under load, with the result that a smooth, continuous flow of power is maintained. The first Audi to sport this innovative technology will be the 250 hp 3.2 liter TT Coupe. Audi is currently evaluating the market to determine whether this vehicle will be available in North America.

<FONT size=2>Most people refer it as Volkswagen DSG (Direct Shift Gearbox) and think the German car maker invented it. In fact, although Audi TT V6 is the first application to this revolutionary gearbox, it was actually developed and is manufactured by transmission giant BorgWarner. Its official name is DualTronic.
In the past several years, we saw waves of revolutionary gearboxes appeared - the sequential manual (Ferrari F1, BMW SMG etc.), the roller-type CVT (Nissan Extroid) and then chain-type CVT (Audi Multitronic). There was also small but useful evolutions such as 6-speed automatic. Compare with engine technology, transmission technology progressed at a much greater speed, helped improving fuel efficiency, acceleration and refinement.

BorgWarner's DualTronic is derived from sequential manual transmission but it provides quicker and smoother shifting compare with the sequential manual currently on sale. Like sequential manuals, it is shifted by wire (e.g. using paddles or buttons, whatever) via electro-hydraulic actuators. However, the biggest difference is the use of 2 multi-plate clutches - one activates the 1st, 3rd and 5th gear, another activates the 2nd, 4th and 6th gear. With 2 clutches, the gearbox can pre-select the next gear for the benefit of quicker response and smoother transition. For example, when the car is accelerating at 2nd, the computer predict the driver will select 3rd soon, thus it will disengage the clutch for odd gears and pre-select 3rd. Then the driver touches the upshift paddle and the computer will disengage the clutch for even gears and engage the clutch for odd gears. As a result, the gearbox shift from 2nd to 3rd quickly and smoothly.

The use of multi-plate clutches instead of single-plate clutch allows finer control of engagement quality. Depends on driving condition and driver’s desire, gearshift can be made ultra-quick (but aggressive), or ultra-smooth (but slow).

Shift quality versus speed has been the main problem of the current generation sequential manual gearbox. DualTronic's pre-selection procedure and finer control of clutch operation help it to beat sequential manual in this respect. No wonder BorgWarner estimates 18% of European cars will use DualTronic technology by 2010. </FONT>
