That sweet Viper was certainly cool, but if you need a sports car that will haul groceries and more than two people, Cadillac has debuted a new version of the powerful CTS-V. Previous versions of the CTS-V were four door cars, but the new one is a coupe.

The new coupe has the same 556HP 6.2 liter V8 engine and can be had with a 6-speed manual or auto transmission. The car also gets magnetic ride suspension and big Brembo brakes.

Here’s one hell of a conceptual design: the Cadillac World Thorium Fuel concept. Otherwise known as the Cadillac WTF. It was created by Loren Kulesus. Everything about the aptly named WTF has been created to last for 100 years without maintenance. That’s the reason for the element number ninety, thorium: to act as a nuclear fuel powering batteries that would power this beast.

Also, every major system is redundant just in case of a failure. Even the wheels are covered and shouldn’t give you much trouble. The wheels don’t have individual tires. In fact, what you get is one combined unit made up of six individual wheels. That gives you 24 wheels in all, and each wheel has its own induction motor just for good measure. According to the creator, “The vehicle would require the tires to be adjusted every five years, but no material would need to be added or subtracted.”
