Audi ’s new and improved seven-speed dual-clutch transmission that will replace the current six-speed DSG unit found in the current A3 and TT is going to be able to take much more torque. Monday’s reports have Audi launching the tranny in the all-new 2009 Audi Q5 SUV later this year, but only in Europe. Around the same time, it should replace the optional six-speed automatic in the 354hp Audi S5 .
The new gearbox will be built at VW’s factory in Kassell, Germany, and will also likely eventually make it into VW models as well.
The current gearbox’ limit is 258lb-ft, while the new unit will be able to handle as much as 406lb-ft, making it suitable for use in high-performance gasoline cars and torque-rich turbo-diesel SUVs. The added torque capacity is thanks to a better cooling system, with a vacuum booster that about doubles the amount of oil that will lubricate the twin clutches, according to Inside Line reports.
A different design that separates the clutches and oil pump makes bolting the new transmission up to longitudinally-mounted engines in Audi ’s Quattro-equipped vehicles possible.
The gearbox will also be matched with future S and RS cars, including the S4 and RS4, as well as the RS5, but so far, the plan is only for European models. The Q5 in North America will retain the company’s six-speed auto, as Audi is worried about Americans complaining of the DSG’s harder-edged shift quality.
