"SE" drive train, 14-inch aluminum wheels, a larger front larger sway bar, and a rear swaybar that were only otherwise available on the SE model. 1991 was the final model year of this body style and it was essentially a carry-over year. The only changes were the addition of an Anti-lock Brakes System (ABS) as standard equipment for all Grand Am SE's (not available to LE's), and all 1991 model year cars fitted with a 5-speed transmission received a redesigned "short throw" shifter. For 1992 the Grand Am entered its fourth generation.

On the SE, an anti-lock braking system (ABS VI) was available. It also received new bodywork and a revised interior. A V6 option returned in the form of the 3.3 L 3300 V6, mated to a three-speed transmission. The 2.3 L I4 came as either a SOHC or DOHC. A high output version of the DOHC was offered as well. A new GT trim was offered that featured new wheels, smoother, yet larger cladding, and more standard equipment. 1993 brought further refinement to the Quad 4. This resulted in a loss of to all engines. In 1994, the V6 and standard 3-speed powertrain were effectively replaced by GM's new 3.1 L 3100 series V6 engine and new 4-speed automatic transmission. A driver's side airbag also became standard for 1994, but the door-mounted automatic seatbelts remained. In 1995, the Quad 4 engines received balance shafts and direct driven power steering off the intake camshaft. The 4-speed automatic that was mated to the 3.1 L in 1994 became optional as a step-up from the 3-speed
