The Citroen Oli (corrugated cardboard honeycombs with fiberglass) and Honda Sustaina C (acrylic resin) concepts are the two most interesting I've seen with small vehicles making a use of new lighter materials. I don't think either has been marked for production yet, and if you're in North America like me, we probably won't ever see them if they do get made.
