Student-Built "Black Widow" Racer Gets 0.09 L/100km

Engineering students at the California Polytechnic State University are showing off the Black Widow, their entry for the upcoming Shell Eco-Marathon contest, and it involves some unusual numbers: 3 (wheels); 3 (horsepower engine); and 2,572 (miles per gallon) (0.09L/100km).

The team has been working on the vehicle since 2005, and with each successive year they've managed to shed weight and ramp up mileage. In its current state it weighs only 44 kilos, and can hit a top speed of 48kph with its Honda 50cc engine.

In the last three Shell Eco-Marathons—a competition for student-made, energy-efficient vehicles—the Black Widow has placed either first or second. The competition takes place at the end of March, and this year the California Polytechnic State team will double its chances by entering a second vehicle, also with three wheels, in the Urban Concept category.

The Black Widow may not be the fastest car or the most powerful, but it will almost certainly get you where you need to go. [Wired via Inhabitat]
