Last week’s miles per gallon (MPG) marathon may have seen drivers attempt to smash previous mpg records recorded by manufacturers, but one pair of car designers may have out done them all.

Craig Henderson and Bill Green claim to have constructed a vehicle that averaged an incredible 113.1mpg during a drive from Canada to Oregon. They claim that the vehicle they drove from the Canada-Washington border to the Washington-Oregon border along Interstate 5 set a new record for fuel efficiency.

The vehicle in question is the Avion, which was named after the French word for airplane (not after the Mike & the Mechanics song Par Avion, just to clear that up!). According to the designers, a prototype version of the vehicle achieved 103.7 mpg during a drive in 1986 but only now is it attracting attention due to the media hype surrounding green cars and the desperation among consumers to achieve greater fuel efficiency.

According to Henderson and Green, the Avion can reach speeds of more than 100mph with just three-six horsepower thanks to its aerodynamic design.
So can these remarkable feats be achieved on a mass produced level? Time will tell as the Avion is scheduled to go into limited production soon.
