The H-body was GM’s subcompact car for the seventies, sold in six different models: Chevrolet Vega and Monza, Pontiac Astre and Sunbird, Buick Skyhawk, and Oldsmobile Starfire. Each model has a 4, 6, or 8-cylinder engine in the front and a solid rear axle to move the car. All bodies are of unit-body construction (no separate frame). All styles have four seats, two doors, and are available in notchback, hatchback, or wagon forms (depending on brand). There are economy- and performace-tuned models. The line was replaced in the early eighties by the transverse front-engined front wheel drive GM J-Body (Chevrolet Cavalier, Pontiac Sunbird, etc.). ??? The H-Bodies were developed by GM Lead Engineer Ed Cole, who also developed the Corvair and Fiero. The Vega was designed with a Chevy Small Block V8 in mind, but the Corvette group protested enough to kill that option. H is the internal code GM used to identify the car platform. For example, some other codes are F for the Camaro and Firebird,
