Ok, I was shocked. The new Car and Driver has a few comparos that are bound to raise some eyebrows. Notably, the S4 beat out (by a sizeable margin) the M3 and absolutely demolished the C32 AMG in the latest comparo. Sorry, I don't have the text of the article on hand, but basically the editors loved the V8 in the S4 and raved about how turbos are nice but really just aren't as good as big displacement. They talk about how the V8 actually weighs the same as the previous S4's 2.7liter 6 cylinder so the weight penalty is kept to a minimal. The S4 weighs nearly 400 lbs more than the M3 but the S4 was the only car to receive a perfect 10 for the "fun to drive" category. I haven't read the full article through yet, just the comments on the M3 and the S4.
