The hypermiling Avion shatters all records!
The car is built with two things in mind: weight and aerodynamics. To achieve a featherweight 1500-lb target, it uses an aluminum monocoque frame with steel front/rear crash and suspension subframes. To the frame a slippery wind tunnel-shaped body made of carbon fiber, kevlar and fiberglass is riveted and bonded in place, yielding a very stiff structure. An 800-cc diesel engine is transversely mounted behind the driver and the rear wheels are powered through a five-speed gearbox.
