Compacts arrive

The decade of the 1960s saw the creation of compact and intermediate classes. The Chevrolet Corvair was a flat 6-cylinder (air cooled) answer to the Volkswagen Beetle, the Chevy II was created to match Ford's conventional Falcon, after sales of the Corvair failed to match its Ford rival, and the Chevrolet Camaro/Pontiac Firebird was GMs counter measure to the Ford Mustang. Among intermediates, the Oldsmobile Cutlass nameplate became so popular during the 1970s that Oldsmobile applied the Cutlass name to most of its products in the 1980s. By the mid 1960s, most of GM's vehicles were built on a few common platforms and in the 1970s GM began to use nearly identical body panel stampings, differing only in internal and external trim items.^{[citation needed]}

The 1971 Chevrolet Vega was GM's launch into the new subcompact class to compete against the import's increasing market share. Problems associated with its innovative aluminum engine led to the model's discontinuation after seven model years in 1977. During the late 1970s, GM would initiate a wave of downsizing starting with the Chevrolet Caprice which was reborn into what was the size of the Chevrolet Chevelle, the Malibu would be the size of the Nova, and the Nova was replaced by the troubled front-wheel drive Chevrolet Citation. In 1976 Chevrolet came out with the rear-wheel drive sub compact Chevette. It was a well built car but couldn't compete with the Japanese imports in overall quality and standard features.^{[citation needed]}
