Current dual motor Teslas use two motors and two differentials. Four big metal cylinders. Although Tesla motors are (probably) more expensive than differentials, for improved performance and efficiency, it would seem to make a lot of sense to offer a motor-per-wheel version. Still four big metal cylinders, but no differentials! (This is not a new concept. Porsche produced a motor/wheel electric car in 1900.) Lohner-Porsche - Wikipedia, the free encyclopedia By my thinking, this would be an intrinsically cleaner and more flexible way to distribute and manage power to the wheels. And it would make it easier for the controller to better manage traction, stability, and skid control. Why is it taking them so long?
