Pending confirmation by the folks at Guinness, a group of students at DeLaSalle high school in Kansas City will be able to say they've built the world's most efficient electric car, a see-thru, F1-style racer that gets 300mpg equivalent.

OK, they got some help from the folks at Bridgestone America, the world's largest tire company, who contributed resources and supplied the team with high-efficiency Ecopia EP100 tires, though the car was conceived of and developed as a class project.

The ultra light weight plug-in electric was built with the customized chassis of 2000 Lola Indy. During a recent test at Bridgestone's Texas Proving Grounds, the car got the equivalent of 300 miles per gallon fuel economy, an amazing feat the students think qualifies for the world record. Their next project? Building a vehicle that harnesses the elusive power of the atomic wedgie. [Automotta via Wired UK]
