The Chevrolet Impala is a full-sized car built by Chevrolet for model years 1958 to 1985, 1994 to 1996, and 2000 to 2020. The Impala was Chevrolet's popular flagship passenger car and was among the better-selling American-made automobiles in the United States
The Impala name was first used for the full-sized 1956 General Motors Motorama show car that bore Corvette-like design cues, especially the grille. It was named Impala after the graceful African antelope, and this animal became the car's logo. Painted emerald green metallic, with a white interior, the Impala concept car featured hardtop styling. Clare MacKichan's design team, along with designers from Pontiac, started to establish basic packaging and dimensions for their shared 1958 General Motors "A" body in June. The first styling sketch that directly influenced the finished Chevrolet automobile was seen by General Motors Styling Vice President Harley Earl in October. Seven months later, the basic design was developed.
The 1962 model featured new "C" pillar styling for all models except the 4-door hardtop. Sport Coupe models now featured the "convertible roof" styling, shared with other GM "B" full-size hardtop coupes, although the less expensive Bel Air hardtop was still available with the 1961-style roofline. This style proved popular. The "overhang" roof style of the sedans was replaced with a wider "C" pillar with wraparound rear window. Engine choices for 1962 included the 348-cubic-inch (5.7 L) V8 discontinued and replaced by the 380 bhp (283 kW) 409-cubic-inch (6.7 L) or 409 bhp (305 kW) 409-cubic-inch (6.7 L) engine. These engines could only be ordered with a manual shift transmission. The small-block 283 was offered with a two barrel carburetor. The 283 was also enlarged to 327-cubic-inch (5.4 L), offered in two versions, one with 250 bhp (186 kW) and one with 300 bhp (224 kW), which added more engine choices for small-block fans. The Beach Boys produced a hit single, "409", referring to the Chevrolet, which became an iconic song for these cars. Impalas again featured premium interior appointments, plusher seats could be done by the dealerships on customer request. And more chrome trim outside, including a full-width aluminum-and-chrome panel to house the triple-unit taillight assembly. Super Sport (SS) models featured that panel in a special engine-turned aluminum, which was also used to fill the side moldings, making the SS more distinctive in appearance. The Impala also gained the top trim station wagon body design, in place of the Chevrolet Nomad model. However, unlike the passenger cars, Impala wagons had dual-unit taillights. Due to reliability problems, the optional Turboglide automatic transmission was discontinued, leaving Powerglide the only automatic transmission available until 1965. A new radio was optional.
