The fifth generation of the Buick Regal debuted in 1997, marking a return to the Regal’s roots as a performance-oriented luxury mid-size sedan. Built on GM’s W-body platform, it shared many similarities with the Pontiac Grand Prix and Chevrolet Impala, but with a more upscale focus. Buick aimed the Regal at buyers seeking both comfort and power, with the top-tier GS (Gran Sport) trim offering substantial performance enhancements. This generation of the Regal remained in production until 2004, blending traditional Buick luxury with sportier, more aggressive driving characteristics.

1997–1999: Introduction of the Fifth Generation

When the 1997 Buick Regal launched, it featured an entirely new design. It was a four-door sedan exclusively, marking the end of the coupe option. The new design was sleeker and more aerodynamic than the previous generation, with a more refined interior layout. The Regal’s target market was mature drivers seeking a combination of performance and luxury.

A standout feature of this generation was the return of the supercharged V6 engine in the Gran Sport (GS) model. This 3.8L L67 Supercharged V6 produced 240 horsepower, making the GS one of the more powerful mid-size sedans available in the late 1990s. This model could go from 0 to 60 mph in about 6.5 seconds, offering impressive performance for the time.

The base model, known as the LS, came with the naturally aspirated version of the 3.8L L36 V6, delivering a respectable 195 horsepower. This engine offered smooth, consistent power with solid fuel efficiency for its class.

2000–2002: Mid-Cycle Refresh and Technological Improvements

In 2000, the Regal underwent a mid-cycle refresh, updating both its aesthetics and technology. The exterior design received subtle enhancements, such as new taillights and a slightly revised front fascia, but the most significant changes were on the inside. Buick focused on improving comfort and integrating more high-tech features, such as OnStar, dual-zone climate control, and a Monsoon premium sound system.

The Regal GS continued to stand out with its supercharged engine, but both models received improvements in suspension and handling to better compete in the performance-oriented segment. Buick also focused on safety, adding features like side-impact airbags and traction control as standard on higher trims.

2003–2004: Final Production Years

As the Regal approached the end of its production cycle in 2004, Buick made only minor changes to the lineup. The LS and GS trims continued, with some optional features becoming standard, such as leather seating and premium sound systems on the GS.

Buick’s marketing in these years continued to emphasize the Regal’s balance of comfort and power, but by 2004, the model was seen as a bit dated compared to its competition. In 2005, the Regal was replaced by the Buick LaCrosse, marking the end of an era for this mid-size sedan.
