In January 1982, GM debuted the downsized fifth-generation Century, using the
front-wheel drive A platform, in coupe and sedan forms. The fifth-generation Century shared the A platform with the
Cutlass Ciera,
Pontiac 6000 and
Chevrolet Celebrity. Together the A-bodies became very popular — as well as some of GM's most transparent examples of
badge engineering, which was highlighted on the cover of the August 22, 1983 issue of
Fortune magazine as examples of near-uniformity, embarrassing the company and prompting GM to recommit to design leadership. In October 1983, a station wagon was added to the lineup to replace the discontinued 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 , with 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 marketed in the mid-1980s under the T-Type name. With Buick's
181 cu in (3.0 L) V6 producing , the Century T-Type's performance was modest, but the
Buick 3.8 V6 SFI engine, producing , offered passable 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 "Chevrolet Century" were sold 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 the import car wave from 1991 (previously new car importations were forbidden in Mexico) and continued in production until the 1996 model year. In Japan it was sold as the Buick Regal because of the
Toyota Century limousine.
1989 facelift 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 tri-shield 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 full-width taillights that followed a Buick tradition of big taillights. The 3300 was introduced in 1989 as a replacement for the 3800 cc engine, offering an increase of 10 horsepower, but a loss of 15 lb-ft of torque. 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. The 1989 model had seatbelts mounted on the b-pillar, for 1990-1996 the seatbelts were mounted on the door. From 1989 to 1992, the Century had a black bumper and side trim, and from 1993 to 1996 the Century had a bodycolored trim. Originally, the Century, as with the rest of the
A-body range, was intended to be phased out in 1990 in favor of the more modern
W-body line of midsized cars. However, the Century (and its sister car, the
Oldsmobile Cutlass Ciera) continued to remain popular nearing the intended end of their production runs. Thus, it was decided that the older Century and Cutlass Ciera would instead continue production as lower priced alternatives to their proposed replacements, the
Regal and
Cutlass Supreme respectively.
1991 facelift For the 1991 model year, the Century received another slight facelift featuring a bigger radiator grille and different headlamps. The interior featured new door panels with the window switches and door lock switches relocated to a more convenient configuration found on more modern cars, where the switch location corresponds with the window location in the car body. This feature never appeared on its sibling the Oldsmobile Ciera, which retained the inline switch bank mounted flush with the door panel, the rear switch being the driver's door window. The Century windows switches were not backlit, but illuminated by a small bulb in the door panel trim above the switch bank. Other interior changes included new seat covers, and relocating the front outboard seat belts from the A-pillar into the door, functioning as "automatic" seat belts so that the belts could be buckled and the door opened and closed while still buckled. The driver and front passenger could enter and exit the vehicle while the seat belt was still fastened. For 1993, the 2.5 L
inline-four was replaced with a new, , 2.2-liter four. For 1994, the slow-selling coupe model was dropped (603 had been sold for 1993, equivalent to 0.5% of overall Century sales), and all models received a standard driver's-side
airbag. Also in 1993, the 3.3 L Buick V6 was replaced with a 3.1 L V6 with the same power rating, and power on the 2.2 L four was up to with the introduction of
MFI. Midway through the 1994 model year, a round speedometer replaced the wide rectangular one, but the car still carried on with the original dash. Despite its dated design, the Century and its sibling the Oldsmobile Cutlass Ciera still sold well during the 1990s and proved both reliable and profitable to GM since their tooling costs had been monetized.
