In 1997, the Century and the Regal once again became versions of the same car, only offered as a four-door sedan, and sitting on a revised W platform that was shared with the Oldsmobile Intrigue, the Pontiac Grand Prix, and the Chevrolet Lumina and Chevrolet Monte Carlo. Differences between the Regal and Century were mostly cosmetic. As the upmarket version, the Regal offered larger engines and fancier trim, and once again boasted a newer version of the 3.8 L V6. While the Century was mainly a reliable, economy-minded car based upon the W-body, the Regal was fitted with many amenities, including heated leather seats (optional on the Century), a Monsoon 8-speaker surround sound system, dual climate control, and expansive interior space. Few changes occurred during this version’s seven-year run. It offered 5-passenger seating on all trim levels like the Pontiac Grand Prix and Oldsmobile Intrigue (formerly Cutlass Supreme), unlike their predecessors that had optional 6-passenger seating and the Buick Century (formerly built on the A platform) which had standard 6-passenger seating.
This period held the fastest Buick since the days of the Grand National, the Buick Regal GS. This car was now supercharged instead of turbocharged, and produced 240 hp (180 kW) and 280 lb·ft (380 N·m) of torque. When introduced in 1997, Buick advertised the Regal as the “car for the supercharged family”. Buick also released two other model types, the LSE and the GSE. The LSE stayed with the 200 hp (150 kW) engine with upgrades and the GSE stayed with the 240 hp (180 kW) supercharged engine with upgrades. Also, in 2000 Buick came out with a concept GSX that had an intercooled 3.8 L, but was supercharged rather than turbocharged. It had 300 hp (220 kW) unlike the original that had 276 hp (206 kW).
The North American Regal was replaced in 2005 by the Buick LaCrosse, also built on the W platform. The final 2004 Buick Regal rolled off the assembly line on June 1, 2004
