1991 Chevrolet Beretta: A driver-side airbag arrived for 1991, and the high performance GTZ could get a V6 engine instead of the standard Quad 4. Accompanying the airbag was a new steering wheel, plus redesigned gauges and controls.

1992 Chevrolet Beretta: Antilock braking became standard for '92, as the base 2.2-liter engine added 15 horsepower. The 3.1-liter V6 again was standard on the GT and optional on base and GTZ Berettas. The GTZ continued to use a standard Quad 4 engine.

1993 Chevrolet Beretta: Base, GT, and GTZ models again went on sale, but the V6 that had been standard on the GT was now optional for all Berettas. The GT's Quad 4 engine dropped five horsepower, due to stricter emissions standards.

1994 Chevrolet Beretta: More-potent engines arrived, a Z26 with new Quad 4 engine replaced the GT/GTZ, and a 4-speed electronic automatic transmission joined the 3-speed. The new 2.2-liter 4-cylinder engine made 120 horsepower (up from 110), and the available V6 gained 20 horsepower (now rated at 160). The dual-overhead-cam 2.3-liter Quad 4 engine, installed in the Z26 coupe, developed 170 horsepower. The new electronic 4-speed automatic was the sole transmission choice for Berettas with V6 power. Door-mounted front shoulder belts replaced the former manual seatbelts.

1995 Chevrolet Beretta: Daytime running lights were added, and the Z26 got V6 power, deleting the Quad 4 engine. Automatic-transmission fluid and spark plugs now required no servicing for 100,000 miles under normal operating conditions.

1996 Chevrolet Beretta: For its final season, the front-drive coupe showed few changes.
