While this one wasn’t revealed at this year’s North American International Auto Show in Detroit, the Cadillac’s World Thorium Fuel Concept is easily a StyleCrave favorite. Flush with futurism and forward thinking design, the WTF (yeah, the WTF) is an electric car concept fueled by a pretty ambitious source.  Created by Loren Kulesus, this concept will be powered by thorium nuclear fuel batteries that are designed to last for some 100 years without maintenance.  The tires on the WTF are actually multi-wheel systems, with each wheel actually being a set of six independent wheels combined on a single axle. While the WTF concept may be little more than a pipedream for production, we can certainly salute its conception. [via Autoblog]
