I never said that engine size is nearly irrelevant because it isn't. Take your 7L sports car you mentioned. How on earth do you gear it so it runs at close to the most efficient load as you cruise along the highway? You can't, it's impossible, unless we're talking about 100mph highways. Will the car still get better fuel mileage than the large infenstation of SUV's and CUV's because it's going to be more areodynamic. But show me a 7L sports car that gets as good of mileage as a Prius.
