Chevrolet Impala (1977–1985)

1977 Chevrolet Impala
The changes in the automobile marketplace resulted in Chevrolet redesigning the Impala once again in 1976 to meet changing demands. The new downsized Impalas were shorter in length, taller and narrower than before. The new Impala's frame was a shortened version of the one introduced in 1970 and would be utilized until 1996 when the B-body production line was shut down. Even with its trimmer exterior dimensions, the new Impala featured increased headroom, rear-seat legroom and trunk space. Production of the downsized model increased substantially over 1976, and the Impala regained the number one US sales position. The redesigned 1977 Impala/Caprice was named Motor Trend's car of the year. The new body was taller and narrower than the 1976 model.

Pillarless hardtops were discontinued, the result of rumors of federal rollover standards looming in the near future. The 1977–1979 coupes sported a double bent tempered rear window similar to the 1987 Chevrolet Monte Carlo Aerocoupe. In 1980, all new sheet-metal was used, although the body style remained similar.

Engine availability was reduced for 1977; the inline-6 was reintroduced with 110 horsepower (82 kW). Options included 267-and-305-cubic-inch (4.4 and 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 from Chevrolet which was totally different from the 3.8 liter (231 cubic inch) V-6 from Buick that was installed in numerous GM models of different divisions.

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 re-branded Caprice starting in 1986, with the upper models being called the Caprice Classic and Caprice Classic Brougham.
