The Future Lightweight Auto

Just read a great article in Jalopnik about a Renault concept car. I've thought quite a bit about the design of the future car, and my version would've used more fiberglass parts instead of plastic, a transmission free electric motor(s) attached to the rear wheel to save weight and cost, and the entire roof, rear & side windows, A/C pillars made of polymer. But I love their design, especially since their the real engineers and production managers.  Alas, unless Nissan uses the design, we'll never see it on this side of the pond.
