as I said in a previous post, it's not just about how much displacement is in the engine, it's also about the weight of the car, both dead, and moving..

a cousin of mine has a Audi S4 dual turbo, which has not quiet as much hp, or top-end speed as his previous car, a camero SS (i belive, it was the high-end model) The S4 is off the line faster, and doesn't "steer like a cow" (he also mentioned it can actualy stop faster too, allways a good thing)

tho I will admit that the S4 is a V6.. not quiet as heavy as the V8, but not as cool as the little 1.8L turbo in the standard A4
