At this year's Shell Eco-marathon Americas event the team from Mater Dei High School shattered last year's record by traveling 2,843.4 miles on a single gallon of gasoline.

The wining "car" looks a lot like a plastic-covered recumbent bicycle. It is interesting that a High School class came up with the winner, and not a team of professional engineers with corporate sponsorship.

Because the contest is sponsored by an oil company, the winner is the internal combustion vehicle with the best MPG. But other kinds of power plants were in the contest.
