Craig Henderson drove 1,478 miles from from Blaine, Washington, to Mexico without stopping to refuel, burning just 12.4 gallons of diesel for a stunning 119.1 mpg.

And he did it in a car he originally designed in 1984.

Henderson rolled into Chula Vista, California, at the wheel of the Avion four days after he left home. The Avion is a car he built with Bill Green 26 years ago as a prototype high-mileage vehicle he hoped to sell. The business floundered, but Henderson never abandoned the Avion. Over the years he’s kept tinkering with it, improving its powertrain and aerodynamics.

At the border.

The car was built with two things in mind: light weight and aerodynamics. To hit the featherweight 1,500-pound target, the car uses an aluminum monocoque frame with steel crash and suspension subframes at the front and rear.

Add some bells and we might have something here.
