2006 Pontiac Grand Prix Review

A well-rounded sedan powered by a variety of engines.

Reviewed by Automotive on


The 2006 Pontiac Grand Prix is a four-door sedan manufactured by General Motors under the Pontiac brand of automobiles. The first generation Pontiac Grand Prix made its debut in 1962 as a successor to the Pontiac G8. Initially, the Grand Prix name covered all cars belonging in the personal luxury class segment. The 2006 Pontiac Grand Prix marks the seventh generation vehicle in the Grand Prix lineup. The Pontiac Grand Prix has undergone several changes in design and specification since its introduction.

The Range

Body Styles: Sedan
Engines: 3.8-liter V-6, 3.8-liter supercharged V-6, 5.3-liter V-8
Transmissions: four-speed automatic
Models: Grand Prix, Grand Prix GT, Grand Prix GXP

What's New

For 2006, the Pontiac Grand Prix largely remains unchanged. Some of the new 2006 Pontiac Grand Prix additions include 17-inch wheels, a body-color grille, lower-body kit, and bright exhaust tips. The interior of the Pontiac Grand Prix also shows an upgrade, with the addition of a shift handle, seat inserts, mini-perforation leather for the steering wheel, chrome rings for the door handles and air vents, and two new interior colors: cashmere/ebony and ebony.


Built on a 110.5-inch wheel base, the overall 2006 Pontiac Grand Prix length measures 198.3 inches. The 2006 Pontiac Grand Prix comes fitted with standard 16-inch wheels, with 17-inch wheels offered as an option on all models. The GXP sedan uses 18-inch tires. The 2006 Pontiac Grand Prix looks unique and recalls vehicles from the muscle-car era. The smooth 2006 Pontiac Grand Prix sides appear like a Coke bottle and stretch up to twin-port grilles with a two-tone lower fascia. The rear-spoiler is flanked by large corner-mounted taillights.


The 2006 Pontiac Grand Prix interior has been redesigned to give it an upscale look. The analog gauges look big and 3-D. Fine satin-nickel accents fit on the doors and give a rich feel. The optional heads-up display that comes standard in the GXP model appears to offer a convenient alternative to the instrument panel during night driving. The instrument panel can be switched off to improve visibility and better convenience during night driving. The 2006 Pontiac Grand Prix offers 16 cubic feet of cargo space.

Performance & Handling

Equipped with powerful engines, the 2006 Pontiac Grand Prix also features Displacement on Demand technology that works to save up to 12 percent of fuel, thereby boosting fuel economy. The base model comes equipped with a 3.8 liter, V-6 engine generating 200 horsepower and 230 lb-ft of torque. The GXP Sedan, the high-end trim, comes equipped with a more powerful 5.3-liter, V-8 engine that generates 303 horsepower and 323 lb-ft of torque, which provides more than enough for daily driving.


The 2006 Pontiac Grand Prix comes equipped with a good list of features, such as a remote anti-theft alarm system, two front and rear headrests, daytime running lights, ventilated front disc/solid rear disc brakes, an engine immobilizer, child seat anchors, dusk-sensing headlamps, front seat belt pretensioners, rear integrated headrests, front height-adjustable headrests, an emergency interior trunk release, and electronic brake force distribution. The 2006 Pontiac Grand Prix earns a good rating of three out of five stars in government crash tests.
