1976 XP-882
Arguably more stunning than the Two- Rotor XP-897GT was the so-called "Four-Rotor Car". Built on the first XP-882 chassis under the aegis of company design chief Bill Mitchell, it carried a pair of GM's experimental two-rotor engines bolted together into a 420 horsepower "super Wankel." A Corvette-like face and obvious high performance potential were taken as strong suggestions that GM was brewing a radical new Corvette for the late Seventies or early Eighties.
