Regal shares a basic design with Buick's conservative Century sedan, but is more similar in market positioning and performance to its other platform-mates, the Oldsmobile Intrigue and Pontiac Grand Prix. Regal comes in LS and uplevel GS sedans. Both have automatic transmission and a V6 engine; the GS adds a supercharger for more power. Antilock 4-wheel disc brakes, a tire-pressure monitor, and traction control are standard. Leather upholstery, side airbag for the driver, and firmer Gran Touring suspension are standard on GS, optional on LS. A package named for fashion designer Joseph Abboud adds power sunroof, and special paint and trim. On LS, the Abboud option brings much of the GS's standard equipment, including Gran Touring suspension and 16-inch wheels. Among the few 2002 changes: Steering-wheel radio controls are newly standard on the GS.
