Teens Build World's Most Fuel-Efficient Car

How many gallons of gas does it take to get from Kansas City to New York? Depends on what you're driving. In this custom-modded Indy race car designed by students at the DeLaSalle Education Center? About four.

WIRED's Autopia reports,

"A team of high school students has developed what it claims is the most energy-efficient car in the world, an electric vehicle that reportedly gets the equivalent of 300 mpg. The school hopes to have it recognized by the Guinness Book of Records.

[The students] had help from Bridgestone America, both at the company's technical center in Ohio and its test track in Texas. The car reportedly achieved the equivalent of 300 mpg during testing there.

The car is built on the chassis of a 2000 Lola Indy, an open-wheeled racer. It has been extensively modified with an ultra-lightweight frame and clear plastic bodywork. The Bridgestone Ecopia EP100 tires increase efficiency by minimizing rolling resistance.

The students built an electric powertrain and made several tweaks to maximize efficiency. Although it's not exactly a mass-production model, the students hope that the car inspires others to work on the fuel efficiency of more consumer-targeted electric cars."
