I was going to disagree with guys who were dissing the Gran coupe to be too long but its almost 3 inches shorter in length then a 7series.
Anyway, if there was no demand for big heavy powerful sedans, we wouldn't have them. But if this car is heavy, what about the trucks like X5m, ml63, Cayenne turbo
