Chev Impala




           


  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.

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 positioned as top of the line Bel Air coupes and convertibles. 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.

It was a change from the 1955–1957 shape that was itself a substantial move away from the conservative Chevrolets of past years, longer, lower, and wider than its predecessors.

The sharp tailfins of the 1957 gave way to deeply sculptured rear fenders.

Three taillights each side would become an Impala hallmark whereas lesser models had two and wagons just one. Special crossed-flag insignias sat above the side moldings plus bright rocker moldings and dummy rear-fender scoops.

1958 was the first year of dual headlamps.



 
    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.


 

 

   The Impala was restyled on the existing GM B platform for 1961.

The new body styling was more trim and boxy than the 1958–60 models. Sport Coupe models featured a "bubbleback" roof line style for '61, and a unique model, the 2-door pillared sedan, was available for 1961 only.



It was rarely ordered and a scarce collectible today. The rare Super Sport (SS) option debuted for 1961. This was also the last year the top station wagon model would bear the Nomad name. Power brakes were $43
  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. All new full-size Chevys eschewed the "X" frame for a full-width perimeter frame, a new body which featured curved, frameless side glass (for pillarless models), sharper angled windshield with newly reshaped vent windows, and redesigned full-coil suspension.

 
 

    In 1961, the Impala SS (Super Sport) was introduced to the market. The SS badge was to become Chevrolet's signature of performance on many models, though it often has been an appearance package only.

The Impala's SS package in 1961 was truly a performance package, beginning with the 348-cubic-inch (5.7 L) V8 engines available with 305 horsepower (227 kW), 340 horsepower (250 kW), and 350 horsepower (260 kW) or the new 409-cubic-inch (6.7 L) V8, which was available with up to 425 horsepower (317 kW).



Unlike all other years, the 1961 Super Sport package was available on any Impala, including sedans and station wagons (the sales brochure shows a 4-door hardtop Sport Sedan with the SS package).

The package also included upgraded tires on station wagon wheels, springs, shocks and special sintered metallic brake linings. Only 142 '61 Impala Super Sports came from the factory with the 409, making it a most rare and desirable collectible.

Starting for the 1962 model year, the Impala SS was an appearance package limited to hardtop coupe and convertible coupe models, available with all engines in the Impala series starting with the base 235-cubic-inch (3.9 L), 135 horsepower (101 kW) inline-6 through 1967, though the big-block engines and heavy-duty parts could still be ordered. In 1967–69, an additional model, the SS427, was available.

 


   
   
   

    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.

A three-speed manual transmission remained standard at the beginning of the year, but in the spring of 1971 all V8-equipped full-size GM cars got Turbo Hydra-Matic as standard equipment.

Interestingly, Powerglide remained optionally available for six-cylinder cars until the 1973 models.

    The changes in the automobile marketplace resulted in Chevrolet redesigning the Impala once again in 1977 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 1971 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.

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.
