GM’s Secret Rotary Corvette: The 4-Rotor Vette That Almost Changed Everything

What if Chevrolet had built a Corvette with a Wankel rotary engine instead of the legendary V8? In the early 1970s, General Motors secretly explored one of the wildest ideas in Corvette history: a mid-engine Corvette powered by rotary technology. Under GM president Ed Cole, Chevrolet developed experimental cars including the XP-897 GT and the four-rotor XP-882 — years before the mid-engine C8 Corvette ever existed. The Four-Rotor Corvette was an extraordinary experiment combining Chevrolet's iconic sports car with an engine architecture that had no conventional pistons, valves, or camshaft. GM believed the compact rotary engine could help create a lighter and more advanced mid-engine sports car. But then everything changed. The 1973 oil crisis sent fuel prices soaring, while emissions and fuel-economy problems made the Wankel increasingly difficult to justify. In 1974, GM abandoned its rotary ambitions. The four-rotor Corvette was transformed into the XP-895 and eventually evolved into the Chevrolet Aerovette — a mid-engine Corvette design that came surprisingly close to production. This is the forgotten story of GM's secret rotary Corvette program, Ed Cole's $50 million Wankel gamble, Zora Arkus-Duntov's experimental Corvette engineering, the Four-Rotor Corvette, and the mid-engine dream that wouldn't become reality until the C8 arrived in 2020.
