My personal definition of a supercar is quite easy compared to yours. Take high power, an unusual design, good performance on the track and a low production run and you get a supercar.
In my personal opinion, there should be only one one hypercar at a time which is the absolute apex of what's technically possible at the moment. The McLaren F1 was such a car, and the Veyron SS is it now. Or to put it simple: hypercars are cars that make people say "WTF???" when they are presented.
