Chevrolet Corvette Four-Rotor - http://carstyling.ru
The Chevrolet Corvette Four-Rotor was a concept car built it the early 1970s.
With exceptional aerodynamics and at just 44 inches high, the Four-Rotor tested out with a drag coefficient of only 0.325.
The Four-Rotor was arguably more stunning than the Two-Rotor XP-897GT. Its Corvette-like face and obvious high performance potential were taken as strong suggestions that GM was brewing a radical new Corvette for the late 1970s or early 1980s.
Three years later, the Four-Rotor was still under a sheet in GM's Special Vehicles warehouse. Like DeLorean (who left GM in a huff during 1972), Mitchell had the car dragged out, this time to replace the double-Wankel with a Chevy 400 V-8.
