Chevrolet Corvair Monza GT (XP-777)

The Chevrolet Corvair Monza GT was an experimental mid‑engined prototype built by General Motors in 1962, based on the early Corvair. It was designed by Larry Shinoda and Tony Lapine at GM, with development led by Bill Mitchell, and built at the GM Technical Center in Warren, Michigan. To create a mid‑engine layout, GM moved the transaxle to the rear and mounted the engine in front of it.

Key features include a canopy‑style body that opens with a front‑hinged roof extending into the B‑pillar, and a rear deck that hinges up. The GT used a standard 145 cu in (2.4 L) Chevrolet Turbo-Air 6 flat‑six engine producing 102 hp, mounted ahead of the transaxle, paired with a four‑speed manual transmission. The chassis, by a team led by Frank Winchell, had a 92 in wheelbase and overall dimensions of 165 in long, 62 in wide, and 41 in high. Notable tech features were magnesium‑alloy wheels, four‑wheel disc brakes, and four fixed seats with adjustable pedals.

Only one monocoque prototype was built. It made its public debut in June 1962 at Elkhart Lake during an SCCA race and quickly impressed enthusiasts, with reporters calling it “gorgeous.” In early 1963 the Monza GT toured with the related Monza SS (XP‑797), a roofless version, for public appearances including the New York Auto Show. Although they shared components, GT and SS were separate design explorations.

Chevrolet planned a production version, XP‑782, for 1966, but it never reached production. The Monza GT remains a landmark GM concept car in the GM Heritage Collection and inspired later designs, including the 1963 Corvette GS‑II mid‑engine concept. Its styling also influenced other GM concepts and production names like the Opel GT and the Mako Shark II.
