Actually, not much of a stretch at all, the size and fuel consumption of our beauties put some folks off from them, so instead they go with something like a 6 banger sedan or convertible. . I can't see where sticking your foot in down in the throttle would be good for gas mileage, except maybe for a very light high horsepower car, where it could brought up to speed quickly then allowed to coast. But as far as our heavy solid luxury machines are concerned, I would think a light throttle foot would be best.
