This polished minivan concept looks like it came from a science fiction movie. Powered by a plug-in hybrid fuel cell, the Airstream runs exclusively on electric power. Ford claims the fuel economy equivalent of 41 MPG for the Airstream. The cockpit features a "floating" instrument panel with touch-sensitive controls. In the rear passenger compartment are contoured seats, and a panoramic display screen that can show entertainment or be used to play games.
