Well, they made that car, the Tesla, that's as powerful as a sports car and lasts as long as one too.
It has a load of batteries in it, which makes it roughly the same weight as a car with an engine. Only it's much more of a dick to recharge than an engine, where you just pour petrol in there.
So with that in mind, you may as well just put an engine on there, it's more convenient. I think they have those already though, not sure.
