innovations like regenerative braking.??????????? The controllers used by those cars are highly sophisticated (read: computerized) and that kind of thinking was not ??????????even available to GM in the 90's with their EV1. The EV 1 used AC Propulsion drive trains. The AC controller with the ac motor made regenerative braking very easy. That is why Tesla and the Rav used ac motors and controllers. Regenerative braking with DC is much more complicated. Bob [Non-text portions of this message have been removed] Yahoo!
