7. Chevrolet Corvette Four Rotor

At the height of the wankel rotary engine craze in the 70’s Chevrolet decided to try and capitalize and make their own rotary engine vehicle. In an effort to be better than everyone else, Chevy created a four rotor concept that featured two two-rotor engines under the hood. The exterior of the vehicle had a wedge front end design, gullwing doors, and a small tail end. The vehicle was never considered for production. GM cancelled all their rotary plans after finding that their prototype engine consumed fuel and oil at very high rates. Since the design of the Four Rotor was so desireable, GM tried to replace the rotary engine with a conventional engine and rename it the Aerovette. That vehicle never saw production either.
