Pontiac Grand Prix Models and Grand Prix History

Next-gen airbags, several new body colors and a new traction control in the GTP model marked the only changes in 1998 for the Grand Prix. In 1999, new low-restriction air-induction and a natural aspiration bumped the 3.8-liter V6 up to 200 horsepower. Updated front door lamps, a new six-speaker sound system, and updates to all trims were also added changes for this model year. The base 3.1-liter V6 got 15 more horses with revised sound dampening and reduced emissions in 2000. This model year also saw an updated anti-theft system, and the limited run of Dayton Pace Car replica (only 2,000 were made). Aside from the Special Edition package, nothing changed for 2001. Similarly, the only big change for 2002 was the 40th Anniversary option. 2003 saw the discontinuation of the coupe, and some major shuffling to upgradable trim levels. A redesign was in store for 2004, boasting a sleeker body style and a revised interior. A V8 GXP trim was added to the fleet in 2005, alongside of updates to all trim levels. 2006s only major change was the addition of the Special Edition package, which featured a signature body style with unique wheels and exhaust tips. The GTP trim was renamed to the GT this year, too. In 2007, a tire-pressure monitoring system was made standard across all models alongside new wheel designs. The GT model was once again dropped, marking the only major change for 2008.
