bahnstormer, you need to do some research on the new S4, dude. Your facts are WAY off.
The new 2004 Audi S4 packs a 4.2 liter V8 pumping out 344hp. The engine is taken from the A6 and was made lighter and more compact to fit in the new S4's hood (it was "shoe-horned" in there, as they say). The car has Quattro AWD, 50:50 weight distribution, 6-speed manual (or 6-speed auto) transmission, 18" wheels, sport suspension, and vented brakes.
The previous S4 (B5 S4, years 2000-2002) had a 2.7 liter twin-turbo V6 pushing 250hp and 258 torque (from 1,950 to 5,500rpm I believe), Quattro AWD, available in a 6-speed manual or 5-speed automatic transmission. You are confused between the both of them.
Anyways, kickass car, elvis, enjoy it!
