The Chevrolet Turbo-Air 6 is a flat-six air-cooled automobile engine developed by General Motors (GM) in the late 1950s for use in the rear-engined Chevrolet Corvair of the 1960s. It was used in the entire Corvair line, as well as a wide variety of other applications.

The Chevrolet Corvair is a rear-engined, air-cooled compact car manufactured by Chevrolet in two generations between 1960–1969. A response to the Volkswagen Beetle, it was produced in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964), and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969). Total production was approximately 1.8 million vehicles from 1960 until 1969.
