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.

You older guys might remember Smokey Yunick's black Chevelle stocker. Nobody could figure out why it was 2-3 mph faster than the pack until a NASCAR official compared another Chevelle side by side with it and discovered the windshield was laid back quite a few degrees from stock.

Templates soon followed.

Smokey is responsible for half of NASCAR's rules.

It's all in how you interpret the rules as written.
When it say's 1" fuel line max, it didn't say you couldn't use a 50' garden hose that held another 2 gallons of gas.,Yeah he got the fuel line rule re-written too.

I also seem to remember a controversy about using the roll cage tubing as a stealthy nitrous bottle.
