The first American car with an air-cooled engine mounted in the back, the Corvair had a split personality. The early models, manufactured from 1960 to 1964, were compact and boxy, and the 1965 to 1969 years evoked a curvy reminder of the Corvette Stingray. The brainchild of Ed Cole, the Chevrolet chief engineer who helped develop the Corvette, the Chevrolet Corvair is forever linked with Ralph Nader, whose 1965 book "Unsafe at Any Speed" alleged the compact car was unusually accident-prone. Less well-publicized was the 1972 safety commission report conducted by Texas A&M University, which found that the 1960 to 1963 models were no more likely to lose control in extremis than similar cars. The Corvair family included convertibles, two-door coupes, four-door station wagons, four-door sedans, and commercial and passenger vans. The Corvair's air-cooled engine became highly sought after by experimental aircraft owners. Because the flat-six Corvair engine has aluminum heads, it is light enough for use in small aircraft. Builders and specialized shops modify the 100-HP and 120-HP engines to match them to propeller in aircrafts that can run on auto gas. Look to the trusted sellers on eBay for a used, restored, or donor Corvair. Aircraft builders can find great deals on Corvair engines, ready to be transformed.
