The Chevrolet Corvair was introduced for the 1960 model year. The first generation of Corvair was a series of compact, rear-engined cars available in sedan, coupe, convertible, and station wagon body styles. These cars were initially powered by an air-cooled, 2.3L flat six engine, but over the course of production, displacement grew to 2.4L (1961-1963), before finally reaching to 2.7L for 1964. In 1961, Chevrolet introduced van and pickup based on Corvair mechanicals. These utilitarian vans and pickups are collectively known as the Corvair 95 (95 inch wheelbase), with the van known as the Chevrolet Greenbrier, and the pickup featuring in the Corvair Pickup market. Production of the first generation Corvair continued until 1964, when it was replaced by the Second Generation Chevrolet Corvair.
