Audi to unveil supercharged S4

We knew that the new Audi S4 was due to be unveiled within the next six months, but CAR was able to confirm that the supercharged sled will make an official appearance at the Paris Motor Show this September. As previously reported, the new S4 will ditch its 4.2-liter V8 in favor of a new supercharged 3.0-liter V6 producing around 350 hp – a few ponies more than the current S4's output.

CAR got the details about the new S4 while running the twin-clutch-equipped S5 through its paces, and is able to confirm that the S-badged sedan will benefit from the same seven-speed gearbox, with shifts taking place in 200 ms. Naturally, the S4 will be equipped with quattro all-wheel-drive, and sales will begin in the UK in early 2009, with wagon and convertible variants following thereafter.

As for the future of the RS4, Audi isn't confirming any specs yet, but they're confident that when the new M3-fighter hits the streets in 2010, the new S-tronic dual-clutch gearbox's shifts will be reduced to around 140-150 ms.
