Nissan already has a history of performance crossovers with things like the Juke Nismo and Juke R, but the company is pushing the idea that a crossover can be a sports car much farther. The teased Gripz Concept has now been unveiled and it is a wild and interesting thing indeed. It looks almost like a 370Z mated with a BMW X4 to create an alien life form with wheels. Speaking of wheels, the rollers on this bad boy are a massive 22-inches, and they features a unique 3-spoke design that was inspired by modern road bikes. There are also no exterior mirrors to make mention of, as everything has been replaced with cameras.
