The Chevrolet Chevelle is a mid-sized automobile that was produced by Chevrolet in three generations for the 1964 through 1978 model years. Part of the General Motors (GM) A-body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles included coupes, sedans, convertibles, and station wagons. The "Super Sport" versions were produced through the 1973 model year, and Lagunas from 1973 through 1976. After a four-year absence, the El Camino was reintroduced as part of the new Chevelle lineup in 1964.
