Avion (car)

The Avion is a prototype sports car that achieves over 119 miles per US gallon (1.98 L/100 km) driving on interstate highways in real world conditions.

The Avion is based on the concept that fuel economy is largely determined by minimizing drag, rolling resistance and weight and matching gear ratio to the required horsepower.

[2][3] Henderson later drove the Avion from Bellingham, Washington to Portland, Oregon, achieving 113.1 mpg.

[4] As of October 2023, the car is on display at the San Diego Air & Space Museum.

It features a lightweight composite body of highly aerodynamic design with butterfly doors attached to an aluminum frame.
