The Chevrolet Chevelle is a mid-sized automobile which was produced by Chevrolet in three generations for the 1964 through 1977 model years. Part of the General Motors (GM) A-Body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles include coupes, sedans, convertibles and station wagons. 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. The Chevelle also provided the platform for the Monte Carlo introduced in 1970. The Malibu, the top of the line model through 1972, completely replaced the Chevelle nameplate for the redesigned, downsized 1978 model year. Three generations of Chevelle were built: 1st Gen (1964-1967), 2nd Gen (1968-1972), and 3rd Gen (1973-1977).
