Eco Factor: Modified airplane consumes 45mpg flying at 207mph.

Klaus Savier has won the Fuelventure 400 competition in a modified VariEze that gets 45mpg while flying at a decent speed of 207mph. The airplane normally flies at 190 KTAS to reach a Prius-like mileage of 50mpg, but if slowed down to extended range, the airplane can hit 100mpg.

To improve the flight efficiency, Savier modified the airplane’s Continental 0-200 engine by adding a computerized fuel injection and ignition systems designed by him.
