The Regal was initially offered in base Custom and upscale Limited trim lines. For 1989, the Gran Sport trim line was added, featuring aluminum wheels, body side cladding and a console-mounted shifter attached to the 4-speed automatic. For 1990, the Regal gained the option of the Buick 3.8 L V6. The 3800 V6 was unique to the Regal, differentiating it from the mechanically similar Chevrolet Lumina, Oldsmobile Cutlass Supreme and Pontiac Grand Prix. Anti-lock brakes were made standard on all but the base Custom cars from 1992, and the grille was redesigned again for 1993. Along with the new look came an electronically controlled automatic transmission and LeSabre-like rear lights and bumper. For 1993, a driver's side airbag was added, along with standard ABS on all models, standard power windows, and more in the base engine due to a revised intake manifold and cylinder head. The Limited coupe was deleted; only the Custom and Gran Sport (GS) coupes remained. Dual airbags were new for 1995 along with a new interior.
