There are blueprints for a vast amount of electric cars in the drawers of all major car producers. As Gene H. would put it: "Been there, driven it!" About 20 years ago I had the privilege to drive a small car from a GM daughter brand (Opel Corsa), driven by four 30 kW flat-built synchronous motors, one mounted fix at each wheel, each powered by an microprocessor controlled IGBT frequency converter from a 400 Volt S.A.F.T. NiCd battery pack. Can you imagine what happens when you apply full power to 120 HP electric motors to a small car? It was a nonpareill pleasure to drive.
The three phase converters had the size of a pineapple can and were filled with pressurized freon which was cooled outside. A friend of mine has developed these converters and equipped such cars for at least three large firms I know of, GM, Volkswagen and Renault. They were fully usable in commuter and other short distance traffic. The VW Caddy was meant for craftsman shops, a little pickup which even had a 220 V AC outlet on the side wall for power drills and grinders. All these cars were presented at the world's largest car fair at Frankfurt (IAA), but nobody seemed to have interest for them. So, the companies have the knowledge, but I guess as long as there is a drop of oil in the world there will be no large amount of those cars produced.
