Via Slashdot, AutoblogGreen describes the Ford Airstream concept. I think I saw this once in a Hot Wheels 10-pack:
Anyway. The Airstream is actually developed in conjunction with Airstream, the company that makes the shiny mobile home trailers. This particular vehicle is a gas/hydrogen hybrid with the hydrogen parts made by Ballard. The drivetrain appears to be the "skateboard" configuration they've been developing.
