Chevrolet Impala (1971–1976)

1971 chevrolet impala
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. In keeping with their huge size, these new "B" body Chevrolets were close to Cadillac in luxury features, styling, and ride.

The 1972 model has a grille which extended below the bumper. Powertrains consisted of mostly V8 engines. The 250 inline six was still standard for Sport Coupe and 4-door sedan models; the 350 2bbl V8 became the standard engine from 1973–1976, with 350 cubic inches (5.7 L), 400 cubic inches (6.6 L), 402 cubic inches (6.6 L) (through 72) or 454 cubic inches (7.4 L) optional. The best-selling body style was the formal-roof Custom Coupe. Beginning in 1972, all engines were designed to run on unleaded gasoline. 1972 saw the last Impala convertible; it sold 6,456 copies, placing fourth with just under 9 percent of the market, right behind the Corvette 6,508, ahead of the Mustang's 6,401.
1973 chevrolet impala
1973 Chevrolets featured a larger, shock-absorbing front bumper due to new federal mandates which required 5-mile-per-hour (8.0 km/h) impact protection. New taillights were mounted in the (still) conventional rear bumper. The convertible was moved upmarket to the Caprice Classic series. Tweaks to the suspension and frame gave better roadability, according to Chevrolet general manager John Z. DeLorean. Steering wheels and instrument panels were color-keyed to interior colors, as opposed to the matte black used in 1971–1972. The steering wheel rim got a soft-feel grip, and replaced the "Impala" badge with generic "Chevrolet." The inline six-cylinder engine was now offered on the Bel Air 4-door sedan only, and only with the 3-speed manual transmission. Interiors had repositioned front seats for more legroom. The Impala name returned for the Kingswood station wagon.

In 1974, the rear bumper was redesigned with shock absorbers to meet the upgraded standards and new tail lights were featured. The front end was also freshened as in previous years, with a new grille and headlight bezels, a new header panel, and a bumper with a drop down center section. The marker lights moved back up beside the headlamps once again. This was the only year of the 1971–1976 models the Impala had a different front end design than the Caprice Classic, as other years used either a grille insert or previous year Caprice front to distinguish the two. The rooflines of the Impala coupes were also revised. For 1974 the Custom Coupe was no longer a hardtop, with large fixed rear quarter glass and a thick B-pillar. The Sport Coupe, still a pillar-less hardtop, now used larger roll-down quarter glass like that of the 1971–1973 Custom Coupe, and had a narrower, fastback style, flat back window. Sedans used carryover body shells from previous years.

A limited-edition Spirit of America package was offered in 1974 on Sport Coupe models; primarily an appearance package, it featured white or blue body paint, a white full vinyl top, white upholstery with red or blue trim, color-keyed seat belts and floormats, special wheel covers, optional white rally wheels, sports-styled dual remote outside rear view mirrors, a vinyl body side molding insert, and red pin-striping. Special fender and dashboard badges announced the package to passers-by and passengers. Chevrolet also offered Nova and Vega Spirit of America versions as well.

The 1975 Impala used a 1974 carried-over Caprice front end, with a grille insert and emblem change. The Caprice model was revised with a new front end with a swept back style header panel with recessed headlight buckets, a new hood, and new fenders. Also in 1975 upholstery, door panels and the dashboard were revised as were the radio and climate control graphics. Speedometers read up to 100 miles per hour (160 km/h), and added kilometers per hour. A High Energy Ignition (HEI) system was officially introduced in 1975, although it was installed on some 1974 cars as a clandestine option. Catalytic converters were also introduced, as were several new options, including an Econominder gauge package (which also included a coolant temperature gauge), intermittent wipers, and a divided 50/50 bench seat with passenger-side recliner (with a choice of sport cloth or vinyl trim). This was the final year of the full-size Chevrolet convertible. Four-door models got new rooflines; the hardtop Sport Sedan got a small triangular "opera window" carved out of the wide roof panel.
1976 chevrolet impala
A Landau model available for 1975–1976 models featured a Landau (automobile) vinyl roof (with a chrome band across the roof), a choice of special paint colors, sports-styled dual remote outside rearview mirrors, color-keyed wheel covers, a vinyl bodyside molding insert, and pin-striping. Inside were color-keyed seat belts and floormats. Fender and dashboard emblems rounded out the package. The 2-door hardtop model (dubbed the "Sport Coupe") was discontinued after 1975, leaving redesigned Custom Coupe, with its wide "B" pillar and fixed rear window, the only 2-door Impala available in 1976. This body style had been introduced for the 1974 model year, a precursor to Detroit's complete abandonment of pillarless body styles before the end of the Seventies. 1976 Impalas used a previous year Caprice nose, with a new "egg crate" grille insert. The Impala had round headlamps while the Caprice used the new quad rectangular ones.
