Car engines: The old motor roars back

We're just delaying the inevitable. Superchargers and turbo's have been in use and refined for a long time. Superchargers rely on horsepower at the crank to power them so to make power you need some power in the first place. Turbos now have variable veins making them less lag prone.

However electric motors produce all the torque at 0 rpm and remains constant to the end. Once we find a suitable battery source I don't see why the IC engine wouldn't be retired to museums and enthusiast garages. But I could be wrong.
