Pontiac Bonneville



Generation 5



For 1971, the Bonneville was moved down in the model hierarchy, as a new top line Grand Ville series was introduced. In effect, it replaced the discontinued Executive between the lower-priced Catalina and the Grand Ville. The Bonneville was offered in three body styles, a pillared four-door sedan, four-door hardtop sedan and two-door hardtop coupe. The standard engine for 1971-72 was a 455 cubic-inch V8 with two-barrel carburetor that was rated at 280 gross horsepower for 1971 and 185 net horsepower for 1972 and optionally available was the four-barrel version of the 455 rated at 325 gross horsepower in 1971 and 250 net horsepower in 1972. The on-paper power ratings reflect the change in power measurement undertaken by the industry for 1972. 1971 was also the first year for Pontiac and other GM divisions to reduce compression ratios on all engines across the board in order to enable use of lower-octane regular leaded, low-lead or unleaded gasoline, thanks to a corporate edict in preparation for the introduction of catalytic converters in 1975 to help meet increasing stringent federal (and California) emission requirements.

In mid-1971, a Turbo-Hydramatic transmission, power steering and power front-disc brakes became standard equipment on Bonneville and other full-sized Pontiacs (as well as other full-sized GM cars).

From 1973 to 1976, the Bonneville's standard engine dropped to a 170-horsepower 400 cubic-inch V8. Optionally available was the 455 four-barrel V8 rated at 250 horsepower (190 kW) for 1973-74 and 200 for 1975-76. In 1973, Bonneville was the only full-sized Pontiac to offer a "Radial Tuned Suspension" option package which included the steel-belted radial tires along with an upgraded suspension with Pliacell shock absorbers and front and rear sway bars. The RTS option was expanded for 1974 to all full-sized Pontiacs and radial-ply tires became standard on all 1975 models though an upgraded "RTS" package was still available as an option.

With the demise of the Grand Ville series after 1975, Bonneville once again became the top-line full-sized Pontiac series, with a Bonneville Brougham model featuring the luxurious interior appointments from the departed Grand Ville.
