The restored, updated version of the vehicle burns diesel and uses a 6-speed semi-automatic manual transmission from a Smart Fortwo. The Avion website claims it only requires 3 to 6 horsepower to maintain highway speed and should reach 100 mph. About the achievement Henderson said, "I am thrilled to be able to break our old record. This was a personal goal achieved for me and now we set our sites on the Progressive Automotive X PRIZE. We are in the process of building another car to compete and hopefully win the X PRIZE and we are seeking corporate or personal sponsorship to help us meet or goals". If you want your own Avion that might be possible as they say they are now "tooling up" to do a limited production run. Hit the jump to do the timewarp with a pair of videos, past and present, to see the Avion in action doing it mileage over-achieving thing.
