In one of the histories, the CD is given as 0.31, which ain't bad at all. What kills you is the total area which is being pushed through the air with a .31 coefficient.

They did a wonderful job with the design of the GMC with a great Cd........ then we hang side view mirrors, roof air conditioners, pods, awnings, etc on the sleek outside and it becomes a brick.
Add 10-15% ethanol and it gets worse :^(
