Odd...(weak car response)
My friend got a rental 2004 audi S4 tiptronic since his C350 was in the shop getting detailed. He was showing me the car and took it for a spin. We went up my street and he floored it and the acceleration was quick as expected but I was surprised that I hardly felt any torque but i don't know why. It's rated at 302 lb/ft but actually felt like 210 lb/ft at the most. He had the tranny in S mode and everything. Just kinda odd because another friend of mine has an 07 A4 2.0t and I swear I felt more torque in that car. Could it just be because we were going uphill?

Part of the torque-response problem in the S4, compared to the C350 is due to the Quattro's AWD, which adds weight and drag....and, of course, as you note, going uphill doesnt help either. Did you have 93-octane premium gas in the S4? If somebody accidentally filled it up with 87 or 89-octane fuel (and it sometimes happens), the computer will retard the spark timing and take HP/Torque out of the motor....even more so with a turbo, because of the large amount of compression to start with.
I'm also assuming that his C350 was not an AWD 4Motion model.

why are you guys measuring it with your butt and back???
I thought it was measured by the neck-snapping or neck whipping backward???
