To showcase its success in NASCAR racing, from 1982 to 1987, Buick introduced the Buick Regal Grand National, Regal T-Type, and the limited-production Buick GNX. Originally introduced as a personal luxury coupe, the Regal was later expanded to a full model line.

From the 1970s to the 1990s, the Regal served as the Buick counterpart of the Pontiac Grand Prix and Oldsmobile Cutlass Supreme. Introduced as a submodel of the Buick Century, the model line is currently in its sixth generation. For nearly its entire production, the Regal has served as the premium mid-size/intermediate offering of the Buick product range. The Buick Regal is a line of mid-size cars marketed by Buick since 1973.
