I belive that someone has added an electric motor to the rear differential of a 4 wheel drive car as a hybridization project. Can't remember what car it was and who dun it.

A potential problem with 4 independantly driven electric motors is that when steering each wheel spins at a slightly different speed. The controller would have to take into account vehicle speed and steering wheel angle to calculate how fast wheel wheel should be spinning. It's doable, but a differential does this much easier.
