I don't know how fast the Th!nk Frost—an electric car that uses treads instead of tires—could go. But since it's a concept, I'd just drool over how cool it looks.
The 2-seat Frost was created by Norsk designed Anders Gloslie as a concept proposal for Th!nk, an electric car company from his country. The cracks in its surface hides the lighting system, while the rear includes massive fans for adjusting the temperature of the electric engine and the interior, as well as sensors that send precise information about weather conditions to the cockpit's screens.
