FactThe 1977 Bonneville lost 14 inches and 800 pounds against the 1976 car, yet gained headroom, rear legroom and trunk space.
The Bonneville was significantly downsized for 1977: it and the Catalina became 14 inches shorter, over four inches narrower and 800 pounds lighter than their 1976 counterparts, while gaining headroom and rear legroom. It stayed on the GM B-body as a coupé, sedan and station wagon, built at Pontiac, Kansas City and Oshawa. Engines ranged from the 3.8 litre Buick V6 through Pontiac, Buick, Chevrolet and Oldsmobile V8s of 4.3 to 6.6 litres, including a 5.7 litre Oldsmobile diesel. It was followed in the U.S. by the Pontiac Parisienne.

Owning one

Pontiac waited until the Bonneville's final year to bring back V8 power: the 2004 GXP got a Cadillac Northstar V8 — the first V8 Bonneville since 1986.
This Bonneville beat every other GM car to a safety milestone: it was the first General Motors vehicle offered with a front passenger airbag.
The SSE rode on self-levelling rear air suspension, and the system brought its own inflator in the trunk.
This Bonneville was the midsize LeMans renamed, because GM planners reasoned a better-known name would spark demand.

Same 455 cubic-inch V8, two ratings: 280 hp in 1971, 185 hp in 1972, because the industry changed how it measured power.
Rivals
Same body, same money, other badges — tap any card to flip.
It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.
Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.
A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.
The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.
The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.
The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.
The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.
This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
