Video: SAE International Supermileage Competition

[MetroMPG]

Mostly a fluff piece, but there are a lot of shots of slick vehicles in action getting insane fuel economy.

Over 30 teams from the U.S., Canada, India and Bahrain participated in the SAE's annual mileage competition June 7-8, 2007 in Marshall, Michigan. The competition requires the development and construction of a single person, fuel efficient vehicle. All vehicles must be powered by a small four-cycle engine, have a minimum of three wheels, and the driver must be fully enclosed to prevent contact with the ground. The winner is based on a combination of best fuel economy and points from technical inspections of the vehicles. The 2006 winner, the University of British Columbia, achieved a record 3,145 miles per gallon!
