The Chevrolet Impala was introduced for the 1958 model year. Deriving its name from the southern African antelope, Chevrolet's most expensive passenger model through 1965 had become the best-selling automobile in the United States, competing against the Ford Galaxie 500 and the Plymouth Fury when full-size models dominated the market. The Impala was distinguished for many years by its symmetrical triple taillights. The Caprice was introduced as a top-line Impala Sport Sedan for the 1965 model year becoming a separate series positioned above the Impala in 1966, which itself remained above the Bel Air and Biscayne.
The Impala continued as Chevrolet's most popular full-size model through the mid-1980s. Between 1994 and 1996, Impala was revived as a muscular 5.7-liter V8–powered version of the Caprice Classic sedan. In 2000, the Impala was re-introduced again as a mainstream front-wheel drive full-size sedan. Ed Cole, Chevrolet's chief engineer in the late 1950s, defined the Impala as a "prestige car within the reach of the average American citizen."
The Impala was introduced in 1958 and was positioned as a top of the line Bel Air in either coupe or convertible. From the windshield pillar rearward, the 1958 Chevrolet Bel Air Impala differed structurally from typical Chevrolets. Hardtops had a slightly shorter greenhouse and longer rear deck, giving the impression of an extended body. More>>

The 1959 Chevrolet Impala was radically reworked sharing bodyshells with lower-end Buicks and Oldsmobiles as well as with Pontiac, part of a GM economy move, Chevrolets rode a wheelbase 11/2 inches longer than before. Atop a new X-frame chassis, roofs sat three inches lower, and bodies measured more than two inches wider overall. The growing size contributed to increased curb weight, one more trend of the times.

1965 - 1970
Totally redesigned in 1965, the Impala set an all-time industry annual sales record of more than 1 million units in the U.S., which has never been bettered.

The Impala remained Chevrolet's top-selling model with the fifth generation. A high-performance big block V8 was still available in the form of the Turbo-Jet 454, which produced 365 hp in 1971, but power decreased as the years went along. The 1971 redesigned B-body would be the largest car ever offered by Chevrolet. The hardtop Sport Coupe continued to be offered; it was a smoothly sloped semi-fastback reminiscent of the 1961 "bubbletop" styling. More>>

IThe changes in the automobile marketplace resulted in Chevrolet redesigning the Impala once again in 1977 to meet changing demands.
