In 1980, all new sheet-metal was used, although the body style remained similar.
The Impala and the upscale Caprice sold well into the early 1980s. The Impala was reduced to the base model full-size Chevrolet and was popular with fleet usage – including taxi and police pursuit vehicles but was discontinued in 1985, while the Caprice continued unchanged until 1990. Upon the demise of the Impala, the base model full-size Chevrolet was rebranded Caprice starting in 1986, with the upper models being called the Caprice Classic and Caprice Classic Brougham.

Engine availability was reduced in 1977; the inline-6 was reintroduced with 110 horsepower (82 kW). Options included 267-cubic-inch (4.4 L) and 305-cubic-inch (5.0 L) V8 engines. The 350-cubic-inch (5.7 L) V8 engine was optional in some years. Oldsmobile's 350-cubic-inch (5.7 L) V8 diesel engine also was available. Starting in 1980, the inline 6 was replaced by a generic 229 cubic-inch V6, originally from Buick but installed in numerous GM models of different divisions.
