2003 Pontiac Grand Prix Review

Has some performance but lags the class in refinement and features.

Reviewed by Automotive on


The 2003 Pontiac Grand Prix is solid performance sedan in its own right. With options for some engine performance as well as decent comfort and features, there isn’t much to knock it for until it stands next to rivals. The competition offers vehicles with as much performance in this price range as the Grand Prix but are more refined and offer a more up-to-date and superior set of features. There isn’t any specific failings as far as the Grand Prix goes, but it lags behind class leaders.

The Range

Body Styles: sedan
Engines: 3.1-Liter V-6, 3.8-Liter V-6
Transmissions: four-speed automatic
Models: Grand Prix SE, Grand Prix GT, Grand Prix GTP

What's New

The 2003 Pontiac Grand Prix coupe has been dropped from the lineup, leaving the SE, GT, and GTP sedans as the remaining trim levels. SE versions have new standard equipment including rear reading lamps, an AM/FM radio and a CD stereo, and a ski pass-through. All Grand Prix models now have a standard overhead console with vanity mirrors and assist handles. A new Limited Edition package for GT and GTP is available that includes special wheels, a new rear spoiler, embroidered floor mats, a monotone lower fascia, blue foglamps, unique badging and door sill plates, white-faced gauges, and special seats with leather inserts and blue stitching. An anti-lock brakes system is now an available option for SE and GT.


The 2003 Pontiac Grand Prix is available in three trims: SE, GT, and the performance-based GTP. The SE starts off with 15-inch steel wheels, power door mirrors, spoiler, and front fog lights. The GT trim adds 16-inch alloy wheels and dual exhaust, while the GTP adds an outside temperature display and a compass.


The 2003 Pontiac Grand Prix has air-conditioning, cruise control, power amenities and an AM/FM stereo with CD player. The GT trim adds a six-way power driver’s seat, while the GTP trim includes OnStar, steering wheel mounted audio controls, and leather trim for the steering wheel and shift knob. OnStar is optional for the SE and GT. Leather upholstery and heated front seats are optional for the GTP, while the GT can add it as an option.

Performance & Handling

The 2003 Pontiac Grand Prix base SE model uses a 3.1-liter V-6 engine that produces 175 horsepower and 195 lb-ft of torque. The mid-range GT model uses a 200 horsepower, 3.8-liter V-6 that makes 225 lb-ft of torque as standard equipment; this setup is optional in SE models. The GTP sedan is equipped with a supercharged version of the 3.8-liter V-6 that kicks out 240 horsepower and 280 lb-ft of torque. All engines hook up to a four-speed automatic transmission. The performance of the Grand Prix varies based on trim choice and thus engine choice. The base SE gets the job done and handles most traffic situations. The GT can sprint from zero to 60 mph in eight seconds and offers some performance. The GTP will really perform getting from zero to 60 mph in just 6.9 seconds and can handle all traffic situations.

The 2003 Pontiac Grand Prix has solid handling, and the ride is stable and comfortable in the SE and GT. The GTP is a bit harsh and bumps will be felt, but this is typical of most vaunted and expensive performance sedans. The noise is fairly low although some tire sound comes through.


The 2003 Pontiac Grand Prix is short on safety equipment; anti-lock brakes and traction control are standard on the GTP and optional on the SE and GT models. Side-impact airbags are not available. Other than bare-bones basics such as electronic brake force distribution and child seat anchors, the only other notable extra that comes standard is a remote anti-theft alarm system. In NHTSA tests, the Grand Prix received scores that are in the middle of the scale: four out of five stars for passenger, driver and rollover safety, three stars for side-impact rear and two stars for side-impact front. The IIHS only performed its frontal offset test, awarding the second highest rating of ""acceptable.""
