Our Take

from the Cars.com expert editorial team

Vehicle Overview
Pontiac revamped its midsize front-wheel-drive Grand Prix sedan for 2004. The Grand Prix enters the 2008 model year with few changes. Three new exterior colors are now offered, and the midlevel GT trim has been dropped, leaving only two trims: the base Grand Prix and high-performance GXP. The Grand Prix competes in the same segment as the Dodge Charger, Ford Taurus and Nissan Maxima.

General Motors' OnStar communication system is standard, as is a tire pressure monitoring system. A TAPshift (Touch Activated Power) system lets the driver of a GXP sedan use paddles on the steering wheel to change the automatic transmission's gears.


Exterior
The Grand Prix's smooth sides are said to be Coke-bottle shaped, a theme that harks back to the muscle-car era. They extend into a twin-port grille and a two-tone lower fascia. Large corner-mounted taillights flank the rear spoiler.

Built on a 110.5-inch wheelbase, the Grand Prix extends to 198.3 inches long overall. Fog lamps are standard on GXP models. Standard wheels measure 16 inches in diameter, but 17-inchers are optional; the GXP gets 18-inch tires.


Interior
Each Grand Prix is spacious enough for five adults. The deep trunk holds 16 cubic feet of cargo, and there's a pass-thru in the 60/40-split folding backseat.

Sizable analog gauges have a 3-D look, and the doors display satin-nickel accents. The GXP's standard head-up display allows the driver to extinguish all instrument panel lighting for enhan...

Sizable analog gauges have a 3-D look, and the doors display satin-nickel accents. The GXP's standard head-up display allows the driver to extinguish all instrument panel lighting for enhanced visibility during night driving.


Under the Hood
A 200-horsepower, 3.8-liter V-6 is standard in the base sedan. Last year's supercharged V-6 engine is no longer offered. In the GXP sedan, a 5.3-liter V-8 generates 303 hp at 5,600 rpm and 323 pounds-feet of torque at 4,400 rpm. The 5.3-liter V-8 uses GM's Active Fuel Management system that shuts downs four cylinders during light-load situations and is claimed to reduce gas consumption by up to 12 percent in certain conditions. All engines drive a four-speed automatic transmission, with the GXP receiving a heavy-duty unit.

Safety
Antilock brakes are standard on GXP models and optional on the base sedan. Side curtain airbags are optional. The GXP has an electronic stability system.

Driving Impressions
Even though the Grand Prix has many appealing features, it doesn't quite compare to European and most Asian models in terms of solidness. It does, however, perform energetically, especially with V-8 power in the GXP. Promising strong passing performance, it accelerates from a standstill with vigor, and the V-8 emits a much throatier, fuller exhaust note than the discontinued supercharged V-6. Pontiac's paddle shifters work well but may suffer a little delay.

The Grand Prix's suspension eases over most road flaws, but it gives the impression of avoiding rather than absorbing them. Good handling without major loss in ride comfort is a bonus with the upper models. Headroom is ample in each seating position, but the optional power sunroof steals some space.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
