Michelin have been tinkering away at this for a long time, they have two motors, one for the drive and one for the active suspension: https://en.wikipedia.org/wiki/Active_Wheel https://en.wikipedia.org/wiki/Active_Wheel Their rival Continental have something a lot more interesting: https://cleantechnica.com/2017/08/14/continental-new-wheel-concept-turns-conventional-wheel-inside/ https://cleantechnica.com/2017/08/14/continental-new-wheel-c... They have an aluminium disc with the rotor on the inside, not the outside, plus the 'spokes' of the wheel hold this oversized disc. The disc does not rust so it suits EVs where the brakes really should not be needed outside of emergencies, and when that happens you don't want the wheels to go round a few times clearing off rust before actual braking kicks in. I am sure that this can also be combined with better aero so that the hub cap is designed to radiate heat rather than direct air in to the brake. I imagine a future where vehicles have an extremely flat and low floor with the wheels pushed to the corner and definitely 'cab-over' to some extent as no bonnet needed. This will be great for users of wheelchairs, pushchairs and hand carts. Particularly if the vehicle drives itself and knows where all the potholes are and has the active suspension to deal with it.
