Is the age of the hydrogen car upon us? This week Riversimple announced plans to launch a 250-mpg fuel cell vehicle that's as affordable as a gas-burning car. The craziest part is that the company won't be selling it: Drivers will instead purchase a monthly plan that includes maintenance, insurance and hydrogen fuel. Meanwhile, Lexus unveiled the LC 500h, a 470-horsepower beast that could very well be the sexiest hybrid ever made. And three friends developed one of the craziest-looking vehicles we've ever seen. It's called the Cedar Rocket, and it's the world's fastest electric log car.
