The Regal nameplate debuted for the 1973 model year as Buick’s upscale, more personal-luxury take on the mid-size Century platform. In its early years it was sold as a premium intermediate model aimed at buyers who wanted Buick comfort in a smaller, more stylish package than the division’s larger sedans. The nameplate later became especially well known in the 1980s for its performance variants, including the turbocharged Grand National, T-Type, and the limited-production GNX, which helped turn the Regal into one of the most recognized Buick enthusiast cars of the era.
The first production run for the Regal in North America ended after the 2004 model year, when Buick replaced it with the LaCrosse. The nameplate then returned for 2011 as a revived, globally sourced sport sedan based on GM’s Opel/Insignia architecture. That second North American era broadened the Regal beyond a traditional sedan, eventually including the Regal GS performance model, the Regal Sportback liftback, and the Regal TourX wagon. The revived Regal remained positioned as Buick’s more driver-focused mid-size offering before being discontinued in the U.S. after the 2020 model year.
Because the Regal nameplate has appeared in separate production periods, it is best understood as a long-running Buick series with distinct eras rather than a single uninterrupted model line.
