Eliica

Having electrical motors inside each wheel is not a disadvantage, it gives other advantages, e.g. avoids power loss in transmission systems. Eliica the fastest electrical car, going at 370 km/h, have motors in each of its 8 wheels.

Wasted motor?

I don't understand why one motor would drive the car and the other manage the suspension. It sounds like a waste of a motor and a LOT of power, especially on a car body that offers little room for wheel travel. Why not gear them so that both motors drive the wheel and the phase difference between them controls the wheel height? Much simpler and efficient.
