DeLaSalle School students build super-efficient electric car that gets 307 mpg

A team of students taking part in the Automobile Design Studio at Kansas City's DeLaSalle School have put together an electric car they think could be the most efficient in the world. Testing on the 7.7 mile oval of Bridgestone's Texas Proving Ground have given them a number that the Automotive X-Prize participants would be jealous of – 307 miles per gallon equivalent.

The students started with a 2000 Lola Indy Car chassis and, with the help of instructor Steve Rees and other mentors, developed an electric drivetrain, covered the racer in a clear shell and outfitted it with a set of low rolling resistance Bridgestone Ecopia EP100 tires. While we can't say whether it is the most efficient electric ever built, the Guinness Book of Records folks have been asked to weigh in on the matter. Hit the jump for a pair of videos discussing the project and showing it being put together and tested. Thanks to everyone who sent this in.
