Excerpt from Inhabitat -
"The Cal Poly Supermileage Team’s wondercar, dubbed the Black Widow, has been under construction since 2005. The 96 pound car has three wheels, a drag coefficient of 0.12, a top speed of 30 MPH, and a modified 3 horsepower Honda 50cc four-stroke engine. It originally clocked in at 861 MPG and has been continuously tweaked to achieve the mileage we see today."
