The Corsica was first sold to rental agencies and to large companies in 1987, prior to mainstream release. The Corsica and Beretta were the second best-selling cars in America in 1988. The base Corsica's door handles were colored silver, while the Corsica LT/LTZ had black-colored handles. One feature that was particularly odd was that some earlier models had a column shifter with a handbrake between the front seats. This configuration was very unusual for this class of sedan. The hatchback was introduced for 1989, as was an LTZ performance package that included many suspension parts from the Beretta. The XT trim was an even more rare and little remembered offering on certain years, which included all the performance parts from the LTZ trim as well as a leather interior and a special body kit and spoiler package designed for GM by a third party supplier.
The base Corsica was dropped leaving the LT and LTZ. Both engines offered were increased in displacement.* Minor changes were made to the interior, mostly around the driver controls.
Hatchback body style was dropped after 1991 model. The Corsica received an extensively updated interior with a standard driver's side airbag and cup holders. Front seatbelts were moved from the doors to the B-pillars. The taillights were redesigned.
The only trim level was the LT.
The LT model took the place of the base model once again.
The 3.1 liter V6 with the OBD-I was replaced with the updated Gen III "3100-series" engine (Option code L82) and an updated OBD system. This new OBD system was not compatible with either OBD-I or OBD-II but included features found in both systems.
The 3 speed automatic transmission was replaced with a 4 speed electronically controlled automatic transmission. Front seat belts were moved from the B-pillars to the doors.
The Corsica became the first American car to be equipped with daytime running lights as standard. Also a new Corsica logo was introduced along with other minor cosmetic exterior changes, such as the introduction of a body-colored grille and side moldings.
