There are cars that run on gas, electric, natural gas, deep-fryer grease from restaurants and, now, wood. A Finnish politician has converted his American-built El Camino to run on woodgas. The 1987 El Camino, affectionately dubbed "El Kamina", or "The Stove", features a woodgas generator taking up about half of the truckbed. El Kamina's 400 Chevy engine can take the 4,400 pound truck around 800 total miles of travel.

I once drove an El Camino at 125 mph but that's an entirely different story.
