Great! I was looking for this image or for the concept in general for the bumper holes thread!

The front wheel well vents are in most of the badass sports cars (Ferrari F40, Enzo, McLaren F1 and P1 and even the Bugatti Veyron, which is made with a low Cd in mind to achieve its high speed record) and they have the engine at the middle, not at the front. In normal sports car they are purely cosmetic, as they are sealed. I know these cars are not ideal when talking about Cd, but maybe we can learn something more about their aerodynamics.
