Edmunds' Expert Review

With the elimination of the GT trim level, we would avoid the 2008 Pontiac Grand Prix. The competition and Pontiac's own new G8 are more refined and better all-around performers.

vehicle overview

A lame duck is an aging or otherwise impaired water fowl that has trouble keeping up with the flock and is an easy target for predators. It's also a politician who's biding his time in office until his elected successor takes over. As far as metaphors go, the 2008 Pontiac Grand Prix nails both lame duck criteria, as an aging midsize sedan out of step with its formidable competition that's about to be replaced by an all-new model. While the two vehicles will overlap for at least one year, the new Australian-made Pontiac G8 is for all intents and purposes the Grand Prix's eventual replacement. For now though, the Grand Prix limps on with even less feathers on its wings for 2008.

The supercharged 260-horsepower V6 that used to reside in the Grand Prix GT is no longer available, leaving the underpowered 200-hp V6 and torque-steer-happy 303-hp V8 as the only choices. It's like Goldilocks discovering that Baby Bear's "just right" chair is out for refinishing. Against midsize family sedans like the Toyota Camry and Honda Accord, the base model falls short in refinement, build quality and interior space. Against V8-powered sedans like the rear-drive Dodge Charger and Pontiac's own G8, the Grand Prix GXP also fails to keep up with the flock.

We suspect that Pontiac dealers will be keen to deal on the Grand Prix. As such, it might make for a decent choice for someone just wanting an inexpensive daily commuter with enough sportiness to entertain on weekends. But given its many shortcomings, however, it's probably evident that the Grand Prix isn't at the top of our "must buy" list. We suggest checking out its many competitors or its spiritual replacement, the G8.

Trim levels & features

The 2008 Pontiac Grand Prix is a four-door sedan available in two trim levels: base and GXP. The base model comes with 16-inch alloy wheels, full power accessories, keyless entry, cruise control, OnStar and a CD player. The GXP features a sport-tuned suspension, 18-inch alloy wheels with performance tires, an upgraded stereo system, heated front seats, leather upholstery, dual-zone automatic climate control and a head-up display. Most of these features are options on the base model, while both trim levels are available with a Sun and Sound package that adds a sunroof and a nine-speaker Monsoon stereo with in-dash six-disc CD player. Other individual options include a navigation system and satellite radio.

2008 Highlights

The GT model and its supercharged V6 are no longer available. There are no other significant changes to the Grand Prix for 2008.

Performance & mpg

There are now only two engines available on the Grand Prix. The base model features a 3.8-liter V6 that produces 200 horsepower and 230 pound-feet of torque. Revised EPA ratings for 2008 indicate it gets 18 mpg city and 28 highway. The Grand Prix GXP represents a huge upgrade, with a 5.3-liter V8 that pumps out 303 hp and 323 lb-ft of torque. Both models are front-drive and come with a four-speed automatic, with the GXP featuring a manual-shift mode. Pontiac claims the GXP will run from zero to 60 mph in 5.9 seconds, but in our testing we measured 6.7 seconds.

Safety

Antilock brakes and traction control are optional on the base model and come standard on the GXP. A tire-pressure monitor is standard on both trims. The GXP also has a stability control system. Full-length side curtain airbags are optional on both models. In NHTSA crash testing, the 2008 Pontiac Grand Prix earned five stars (out of five) for its protection of the driver in head-on collisions. The front passenger position earned a four-star rating. In NHTSA's side-impact tests, the Grand Prix scored three out of five stars (for front and rear occupants), but the car tested did not have the side curtain airbags. In IIHS frontal offset testing, the Grand Prix earned a "Good" rating, the highest out of four, while that agency's side-impact testing (with side curtain airbags) resulted in a "Marginal" rating, the second lowest.

Driving

On twistier thoroughfares, the 2008 Pontiac Grand Prix feels larger than most of its competitors, which is perhaps not much of a surprise when you consider that it's almost 10 inches longer than the Toyota Camry. In its favor, though, the Grand Prix is still fairly tight and tossable for a front-wheel-drive car. The base V6 is noisier than those in more refined competitors and fuel economy is less than average. The GXP is also not very composed, as the heavy V8 in its nose blunts the ability of the car to turn in crisply and make quick transitions. It's also rather thirsty and is prone to torque steer (the tendency of a powerful front-driver to pull to one side under hard acceleration). We used to recommend the supercharged V6 model, but alas, it is no longer available.

Interior

The Grand Prix features the last generation of GM build quality and materials, which not only puts it a few steps behind the competition, but behind GM's newer vehicles as well. The stereo panel is particularly out of date, while the surrounding pebbled plastics look and feel cheap.

A quick inspection of interior dimensions may seemingly reveal that the Grand Prix has comparable accommodations to other midsize sedans, but as Stephen Colbert might say, "facts can be deceiving." The rear bench is hard and situated low on the floor, causing a splayed, knees-to-the-ears seating position. This design is to counteract the sloping roofline, which still manages to chew into headroom. At least the back doors open up to 90 degrees, making access to the backseat more pleasant than actually sitting in it. The trunk does have a respectable 16 cubic feet of luggage-swallowing space, plus the rear seat and front passenger seat fold flat to allow a 10-foot Persian rug to ride shotgun.

GRAND PRIX GXP 2008-STILL THE BEST
awos,05/31/2013
Just an update on my 2008 GXP. I have 55,000 miles on it now and still running like new. It's hard to believe that most car mags blasted this car. This car will run with most sports sedans and knock the hell out of the rest. If you can find one thats been maintained, oil changes and the like, BUY IT. I'm 6' 3"" tall and 230 lbs and the leather seats are still in great shape. Why Pontiac was killed is a shame. Bring it back, somebody.
Pontiac shouldn't have left us
Tom rauch,12/30/2015
After owning the car for about a year, I have gone through all 4 seasons. Spring, good. Summer, alright with the exception of the tranny running hot. Fall, good. Winte... now getting 2 feet of snow in a week, icy roads and a v8. I was nervous, but with stability control, abs, and traction control I found myself more relaxed through the winter then I thought I would be. This car has truly surprised me with it winter capabilities. I snowboard and so I need room for my gear, and also need to get up the mountain. This car has proved itself worthy. Now fuel economy for me is about 22 mpg, I drive 60 miles a day just for work and plus all of my running around is in this car. For a v8 and me having a heavy foot sometimes, I can't complain. Which brings me to my next point. This car is quiet, but if you open her up she has a growl that is just beautiful. Not to much and not to little. The interior is... Well the hud is nice, I love the seats, butt warmers, dual auto climate control, and dic. However the plastics rattle Alot. It is in my opinion the biggest down side to the car. I am aproaching 120k miles, and do regular maintenance, along with preventative maintenance, and have had no major issues yet. The value had gone down to much, so if you wanted one now is the time for 4 or 5 grand. I am happy with this car so far after putting almost 50k miles on it and hope it keeps me that way.

I have had my red GXP for 3 1/2 yrs now. She got 48,000 miles on her and no problems, here that Consumers Report, Car & Driver and rest of critics. The car preforms day in and day out. Fast, comfortable and reliable. I am 6'2" and there's plenty of room Interior is standing up better than expected.
Gxp, Pontiac's best
AL,06/01/2010
Have had this car for a year now, the only repair we have had was a flat tire. They best car we have owned! For someone who is big, comfort is excellent. Power is enough too put down most cars. Why they axed Pontiac is a crime.

Should I lease or buy a 2008 Pontiac Grand Prix?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
