I think John's got it. At the track, I've noticed a lot of drivers who open their engine lids but, relative to other cars, there was virtually no heat coming out of my C4's engine compartment. The 996s, on the other hand, radiated heat like an oven.

I've also noticed that the only way to cool down my car on a hot day is to jump on the interstate and cruise at around 80 mph for 20 mintutes. No, seriously!
