This listing is for a 1972 Honda 600 sedan experimental eco-car. It was modified in the 1980's into a wind-cheating, fuel-efficient vehicle in an effort to maximize MPG. The original car chassis was lengthened in the front to allow for the addition of a second engine. The 2-cylinder engine mounted in front is believed to be the original Honda 600 variant with Serial Number N600E-1507852. The second engine mounted closer to the firewall appears to be a single-cylinder diesel of unknown origin. The two engines are apparently linked together utilizing a belt-drive pulley similar to what is found in a snowmobile. Two separate fuel tanks are mounted high on the firewall. The custom front nosepiece is constructed of aluminum and fiberglass and is mounted using machine screws around the firewall area. It is in need of minor repair as shown.
