1991 Pontiac Grand Prix: Although the limited-edition Grand Prix Turbo coupe has been retired, the GTP retains the Turbo model's flared fenders, hood louvers, and lacy alloys wheels. In place of the turbocharged 3.1-liter V6 sits a brand-new 3.4-liter, double-overhead-cam, 24-valve V6. Where the turbocharged engine provided 205 horsepower, the new engine delivers 210 horsepower with a 5-speed manual and 200 horsepower with GM's new electronically controlled 4-speed automatic. The new engine is an available option on all other Grand Prix models, except the LE sedan. Also, all coupes get new front-end styling marked by a new grille, four mini headlamps, and standard fog lamps.

1992 Pontiac Grand Prix: For '92 all Grand Prix models adopt the front-end look of last year's STE model, while the 3.1-liter V6 becomes standard equipment and antilock brakes are more readily available.

1993 Pontiac Grand Prix: A 4-speed automatic transmission is newly available with the base 3.1-liter V6, and automatic door locks are now standard on all versions of the Grand Prix. To get a car comparable to last year's GTP requires specifying the optional 3.4-liter V6, along with the Aero Performance Package.

1994 Pontiac Grand Prix: Heading the list of changes to the '94 Grand Prix are dual airbags, a simplified model lineup, and a new base engine. With dual airbags standard, the seatbelt anchors have been moved to the door frame on sedans, but remain anchored to the doors of all coupe models. As part of the model-simplification plan, only the SE model returns in both 2-door and 4-door formats, as both LE and STE sedan models are dropped, along with the GT and GTP coupe. With the model change, antilock brakes become optional on all models. Taking a look at powertrains, the base engine remains a 3.1-liter V6, but this year's unit is an entirely new design, and makes 160 horsepower compared to 140 from the previous V6. The optional twin-cam 3.4-liter V6 has been upgraded to produce 210 horsepower with the 4-speed automatic.

1995 Pontiac Grand Prix: With all the adjustments made last year, few changes were made to the 1995 Grand Prix.

1996 Pontiac Grand Prix: A variety of detail changes to the Grand Prix took place in its last year prior to a complete makeover for 1997. This year the optional 3.4-liter 24-valve V6 engine provides 215 horsepower, five more than last year.
