Built in 1972, the Corvette 4-Rotor experimental car debuted at the Paris Auto Salon in 1973. The 4-Rotor was one of many ’Vette-inspired specialty cars that pushed the envelope of radical changes – changes that were never adopted for production partly because of cost/feasibility issues, and partly because they just didn’t fit within Corvette’s established character. These ideas included gull-wing doors, and a mid-ship mounted Wankel™ rotary engine. The 4-Rotor featured high-tech interior displays and readouts and aerodynamic styling that influenced future Corvette designs.
