Thanks hagon! That's great news on the controller. Yeah, that's exactly what I was thinking. You could use 4 hub motors and eliminate losses in the transmission, drive shaft, etc. That's still a total power of 24kw, but that should be enough to run a small car. The motors should be light enough to not mess too much with the suspension. They weight so little that even with a fairly heavy battery pack the car should end up lighter. The motors should also be in an area then with plenty of airflow to help cool them down. This could end up being a fairly cheap system to convert a car to electric. You could probably just wire a bunch of the Li polymer batteries that are already intended for the motors into a bigger pack. I found a place on Ebay that if the shipping can be combined for several packs, the cost per kwh would be around $160. If you're interested I'll post the link.

Thanks DawidvC. If it's possible to get that sorted out, they should make pretty good hub motors.
