Jay explores the most exciting alternatives to standard fuel, meets up with Arnold Schwarzenegger to check out the Governator's G-Wagon, and goes deep into rural California to revisit a time when burning wood could run cars.

Jay explores tiny cars and big machines; crushes things in a tank with Arnold Schwarzenegger; drives a dwarf replica car with Brad Garrett; tours Lane Motor Museum's wackiest micro cars; and looks at a Hennessey truck named for a dinosaur.
