The second generation of Chevrolet Chevelle was introduced for the 1968 model year. This updated generation of Chevelle saw updated styling, as well as improved mechanics. Like the previous generation, a wide range of body styles were offered, including the 300 sedan, hardtop, convertible, 2 door sedan, station wagon (Nomad), and coupe utility (El Camino). Ten engine options were available, with two inline six units and eight V8 units with the mighty big block 454ci unit having the largest displacement. A range of Standard Variants were built, while the most notable variants were the Malibu , SS, COPO and Yenko versions. Production of the second generation lasted until 1972, when it was replaced by the Third Generation Chevrolet Chevelle.
