Their engines were already half the size of NASCAR. You want to get green engines going, have NASCAR force engine builders to use a stock modern 6 cylinder engine the same as the car model they are simulating uses as the beginning basis for a race engine - not an up-dated version of a 1960's V8 fuel hog. Oh - but that would ruin the end of the race fuel mileage strategy, wouldn't it? Okay - also limits fuel cells to 10 gallons. Racing results would most likely take a back seat to corporate fuel averages at the Big 3 so the engine race would not be reved up again.
