Just to help keep a VERY complex subject simple, I figured a Miata would be a good comparison. Similiar size, weight, shape with smaller frontal area.

BUT Patrickt brought up an interesting comparison with the Lambo, which apparently has very little frontal area and yet a CD similiar to a Cobra??

Which reminds me of the testing Shelby did when he first started working on the Ford GT-40. Overheating, terrible drag, low top speed. Due mostly, as I recall, to the many "air scoops" here there and everywhere. Which may be the Lambo's problem, big ass air scoops.

Thats some impressive work Greg!
