The Pontiac Bonneville was a full-sized automobile (mid-size car from 1982 to 1986) which was built by Pontiac from 1957 to 2005. It was introduced as a limited production performance convertible during the 1957 model year. The Bonneville (known as the Parisienne in Canada until 1981), and its platform partner, the Grand Ville, are some of the largest Pontiacs ever built; in station wagon body styles they reached just over 19 feet (5.8 m) long, and were also some of the heaviest cars produced at the time (2.5 short tons, 5,000 lb or 2,300 kg).
The Bonneville remained Pontiac's costliest and most luxurious model throughout the 1960s and was instrumental in pushing Pontiac to third place in sales from 1962 to 1970.
The distinctive protruding grille made its appearance on all Pontiac products during the early 1960s, and was a modern revival of a similar appearance on Pontiac products during the 1930s and early 1940s, as demonstrated on the Pontiac Torpedo.
The Bonneville differed from its lesser Catalina and Star Chief counterparts by featuring more luxurious interior trim with upgraded cloth and Morrokide vinyl or expanded Morrokide upholstery in sedans and coupes, expanded Morrokide in Safari wagons and genuine leather seating in convertibles. Bonnevilles (with the exception of Bonneville Safari station wagons) were also (along with Star Chiefs) built on a longer wheelbase version of GM's B-Body. Also found in the Bonneville were instrument panels and door panels with walnut veneer trim, carpeted lower door panels, grab bar on the passenger side of the dash and courtesy lights and a rear arm rest. Beginning in 1964, a Bonneville Brougham option package was available that included an even more luxurious interior trim level with front and rear seats featuring center armrests, upgraded door panels and a standard Cordova (vinyl) roof with "Brougham" nameplates. The two-door hardtop was marketed as the "Sports Coupe", the four door pillarless models were called "Vistas".
Bonneville models were standard equipped with Hydra-Matic (through 1964) or Turbo Hydra-Matic (1965-on) automatic transmissions. Other options included power steering and power brakes as well as air conditioning. Other popular options included power windows, power seats, radio, cruise control, and 8-lug aluminum wheels that included integral brake drums for improved stopping power. The Bonneville also had more powerful standard V8 engines than other full-sized Pontiacs including the 389 cu in (6.4 l) or 400 cu in (6.6 l) V8s with four-barrel carburetors (power ratings of 303 to 340 hp (226 to 254 kW) depending on year) with many optional V8 offerings available including Tri-Power (three two-barrel carburetor) options on both the 389 cu in (6.4 l) and 421 cu in (6.9 l) V8s that offered up to 376 hp (280 kW) through 1966. For 1962, Pontiac also offered the 421 cu in (6.9 l) Super Duty with two four-barrel carburetors, rated at 405 hp (302 kW), as a US$2,250 option (when the base Bonneville listed at US$3,349).
