Students of DeLaSalle School in Kansas City, Mo., have developed an electric car which has been successfully tested on Bridgestone’s Texas Proving Grounds. It’s a plug-in electric car, built on the chassis of 2000 Lola Indy.
DeLaSalle electric car features ultra light-weight aerodynamic body, dressed with Bridgestone Ecopia EP100 tires. It was a part of the class project, based on electric propulsion.
During test on Bridgestone’s Texas Proving Grounds it managed to get the equivalent of a 300mpg fuel economy and developers have already send a request to the Guinness World Records to consider their work.
Student of DeLaSalle School has achived this feat with the help of engineers from Bridgestone Americas’ Technical Center in Akron, Ohio.

Measuring an all electric vehicle's environmental impact or efficiency by "MPG" is about as useful as tits on a bull.
Bring on the tech. Shoot, even Toyota posts their Cd numbers. That article leaves me wanting.
A lot.
I bet they could get another 10 "MPG" by using low rolling resistance tires instead of those track slicks.
Our Solar Challenge II solar car had infinity "MPG", and that was 10 years ago.

how much coal does it take to produce the electricity? how much oil does it take to produce the components and solar panels that might power it? what is the environmental impact of the dam that supplies electricity? I'm with Zak: this is a cool concept but we have to get past talking about MPG for electric cars.
I dig the "visible man/woman" body on it.

i still want a car that burps kittens out of the exhaust pipe. now that would be impressive.

Track slicks?

The Ecopia EP100 is one of Bridgestone's ecologically oriented Grand Touring Summer tires developed for coupe and sedan drivers looking to combine traction, handling and comfort with reduced environmental impact. Ecopia EP100 tires are designed to enhance vehicle fuel economy by reducing tire rolling resistance along with the vehicle's carbon dioxide (CO2) emissions during operation. The Ecopia EP100 is designed for dry and wet conditions, but like all summer tires is not intended to be driven in near-freezing temperatures, through snow or on ice.
The Ecopia EP100 employs a tread compound that applies Bridgestone's unique NanoPro-Tech (Nanostructure-Oriented Properties Control Technology) to reduce rolling resistance and energy loss while maintaining wet traction. This compound is molded into a symmetric tread design featuring rib-linked blocks nestled close together to provide uniform footprint pressure combined with high-angle, lateral grooves to further enhance braking in wet conditions. The tire also features three-dimensional (3D) curves on the tread block surface to suppress noise generated when the block is in contact with the road.

Eh, while I just looked at the tyres and made assumptions from that, reading the tech behind the them, I'm still not impressed with the 10% reduction in rolling resistance.
I just think that if the team was going to use a race car chassis and custom everything else, they would do a bit better than 10%. The Michelin solar tires are 1/30 of the combined Cd and Fr.
But when you are using the Bridgestone testing track, you probably can't use Michelin tires.
