The Chevrolet Impala is a full-size automobile built by the Chevrolet division of General Motors 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.

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. Its tailfins protruded outward rather than upward. Auto tester Tom McCahill, of Mechanix Illustrated, declared that a Chevy’s decklid had “enough room to land a Piper Cub.” Chevrolet eschewed the triple-taillight rear style this year with a very large, single controversial “teardrop” taillight at each side.

Right-hand drive cars were made in Oshawa, Canada, for New Zealand, Australia and South Africa and assembled locally from CKD or SKD kits. The RHD dashboard was a mirror image of the 1959 Chevrolet panel and shared with equivalent RHD Pontiac models. Australian models were assembled by hand on the GMH Holden assembly lines.
