The Chevelle was intended to compete with the Ford Fairlane, and to return to the Chevrolet lineup a model similar in size and concept to the popular 1955-57 models. Enthusiasts were quick to notice that the Chevelle’s 115-inch wheelbase was the same as that of the 1955-57 Chevy. Two-door hardtop coupes, and convertibles, four-door sedans, and four-door station wagons were offered throughout the entire run. In line with other Chevrolet series, the two-door hardtops were called Sport coupes. Four-door hardtops, dubbed Sport Sedans, were available (1966 through 1972). A two-door station wagon was available in 1964 and 1965 in the base 300 series. Various wagons were sold with exclusive nameplates: Greenbrier, Concours, and Concours Estate. Six-cylinder and V8 power was offered across the board. The Chevelle was the basis for the Beaumont, a re-trimmed model sold only in Canada by Pontiac dealers through 1969.
The 1972 Chevelles wore single-unit parking/side marker lights on their front fenders, outside of a revised twin-bar grille. All Malibus had concealed wipers. The 1972 Chevelle series had wide enough appeal to qualify as America's second-best-selling car. Powertrain options included the 175-horsepower 350-cubic-inch V8 and 240-horsepower 402-cubic-inch (still known as a 396), as well as a 454 that managed to put out 270 horsepower (200 kW) under the net rating system.
