In January 1982, another downsized Century arrived, this time on the front-wheel drive A platform, in coupe and sedan forms.
In October 1983, a station wagon was added to the lineup to replace the departed Regal wagon.
The 1984 model year also had an Olympic version of the Buick Century, commemorating the 1984 games in Los Angeles, California.
In 1985, all 1986 versions were "freshened" with a new, more angular front fascia.
Wheelbase was 104.9 in (2,664 mm), with 189 in (4,801 mm) overall length.
Both four-cylinder gasoline units and diesel V6 engines were offered in this generation, although neither became popular.
Performance versions of several Buick models, including the Century coupe, were offered in the mid-1980s under the T-Type name.
With Buick's 181 cu in (3.0 L) V6 producing 110 hp (82 kW), the Century T-Type's performance was modest, but the 3.8 SFI engine, producing 140–150 hp (104–112 kW), offered spirited performance in this comparatively lightweight vehicle.

For 1985 and 1986, Hess & Eisenhardt/Car Craft of Lima, Ohio converted 124 finished Buick Century coupes into coachbuilt convertibles.
Although these convertibles were sold as new cars through Buick dealerships, these conversions were not factory authorized.
In 1986, the engine distributor was replaced by a coil-pack ignition system that proved to be far more reliable than the system that it replaced.
The Venezuelan-built models were sold as the "Chevrolet Century" in South America and the Caribbean.
In Mexico, it was sold as the Century Limited (with no brand, although it wears the Buick logos).
Introduced for 1984, it was the top model for General Motors Mexico, and it survived successfully the import car wave from 1991 (previously new car importations were forbidden in Mexico) and continued in production until the 1996 model year.

The Century received a facelift in late 1988 for the 1989 model year, gaining a new more-rounded roofline, but continuing on the A-body platform.
Black plastic inserts with the Buick trishield emblem replaced the rear quarter windows.
The front end received flush headlamps and a rounded grille, and the stand-up hood ornament was now standard.
All sedan models were easily distinguished by their distinctive full-width tail lights, a somewhat extravagant flourish on a smaller sedan, but one that carried on a Buick tradition of big tail lights.
The 3300 was introduced in 1989 as a lower-powered alternative to the 3800 cc power plant.
The smaller engine featured multiport fuel injection, waste spark distributor-less ignition controlled by the ECM after startup, but had no balance shaft.
An interior refresh came in 1989 for 1990 models.
