Is this a news flash? I thought it was pretty obvious that fuel economy CAFE averages is what ties the hands of the designers.
Compare a 65 GTO drag coefficient to a 05 GTO and it's probably twice that of the 05 car. Ive owned both and know that drafting a semi with a 65 made much more difference than my 05 does. The windshield rake alone makes a huge difference not even taking into consideration the other body contours that help drop drag. My 05 even has a plastic pan under the trunk to smooth out the air flow under the car.
