First of all, the guy in the Z4 may have just played him and didn't even bother stepping on it, so it looks like the Golf took him out.
Secondly, don't judge a car by the badge on it. You never know what's under the hood. I've seen Civics blow away a 355, 5.0 Stangs and Vettes in 1/4 mile from a standstill.
