They will be all wheel drive with a motor at each wheel with zero loss through a drive train. I have a Rayeo electric outboard motor on a pontoon boat that uses a Briggs & Stratton Etek brushless pancake motor. Four group 27 in series will do 8 mph. It's not powerful enough for a vehicle obviously but it could easily fit in the backside of many wheels. Motors at the wheel will provide anti lock braking, traction control and regenerative braking with only two bearings to wear out. The wheel could become half of the motor for further efficiency. The electric cars of today are still pretty crude compared to what we will have in 10 or 20 years.
EtekNot a trolling motor :)
