Craig Henderson started his odyssey near the Canadian border in Blaine, Washington, in a high-mileage prototype he built in 1984 called the Avion. He ended it in Mexico, after traveling nearly 1,500 miles along I-5. And in between he didn't have to fill up once.
With an aluminum frame and carbon fiber body, the Avion is about as light and aerodynamic as you can get for a roadster, two factors that helped Henderson get an incredible 119 miles per gallon on his trip.
Henderson says he has plans to build a couple Avions in a limited production run. In the meantime he'll focus on his other hobby: driving past gas stations whilst giggling uncontrollably.
