2006 PONTIAC GRAND PRIX
The Pontiac Grand Prix sedan was reworked for the 2004 model year. The 2006 Pontiac Grand Prix, now in its ninth generation, shares aesthetic cues with the automaker’s newest GTO. The 2005 model year saw the introduction of the GXP sedan, which had a 5.3-liter V-8 engine. The GTP and Comp G packages will no longer be available in 2006. Grand Prix, Pontiac’s midsize sedan, is also targeted at potential import customers, and the current model offers more refinement than ever before. Improved engines, ride and handling, and cockpit design with big gauges and straightforward controls made the Pontiac Grand Prix more enjoyable to drive in 2004. Unfortunately, there is space for improvement in the quality of the materials and workmanship.
Performance and Fuel Economy
The basic sedan comes with a 200-horsepower, 3.8-liter V-6 engine. The GT sedan has a 260-horsepower supercharged engine. At 5,600 rpm and 4,400 rpm, a 5.3-liter V-8 engine in the GXP sedan produces 303 horsepower and 323 lb-ft of torque. A four-speed automatic gearbox is standard equipment for all engines. The 2006 Pontiac Grand Prix comes with three strong engines: a basic model with 200 horsepower, a GT model with 260 horsepower, or a 303 horsepower V8 (GXP). The Grand Prix GT and GXP have more than enough power to make daily driving an enjoyable experience, but only if you keep your acceleration bursts to straight lines. Due to the weight of the V8, the GXP variant is less agile in corners and suffers torque steer under hard acceleration.
Design
As a nod to the muscle car era, the Grand Prix’s smooth sides are supposed to be Coke-bottle-shaped. A two-tone lower fascia completes the look of the twin-port grilles. Large corner-mounted taillights flank the rear spoiler. The Grand Prix had a wheelbase of 110.5 inches, making it 198.3 inches long. On GT and GXP variants, fog lights are included as standard equipment. There are standard 16-inch wheels, but 17-inch wheels are available; the GXP has 18-inch tires.
Cabin Room and Cargo
Each 2006 Grand Prix has enough room for five people to spread out and relax comfortably. The 60/40-split, folding backseat has a pass-through and a 16-cubic-foot trunk. The doors feature satin-nickel embellishments, and the analog gauges offer a 3-D effect. Pontiac’s optional head-up display (standard in the GXP) lets the driver turn off all instrument panel illumination when driving at night.
Minor Negatives
Although the 2006 Pontiac Grand Prix has a lot going for it, it lacks the sturdiness of European and the vast majority of Asian versions. The Grand Prix is a high-energy performer, particularly when equipped with a supercharged engine. Although it accelerates quickly from a standstill, the lack of supercharged activity is evident. The paddle shifters in Pontiac’s cars function well, although they may be slow to respond. However, despite the Grand Prix’s suspension’s ability to smooth out most road imperfections, it seems to avoid rather than absorb them. There is no substantial reduction in riding comfort when upgrading to the higher variants. The optional motorized sunroof eats up part of the headroom in each seat.
Ride
The suspension calibration of the Grand Prix GXP is exceptional, as it befits its status as the pinnacle of the Grand Prix series. The GXP’s suspension has been retuned to lower by 9 mm, giving it a more aggressive appearance. A 17.2-mm hollow rear stabilizer bar and gas-charged Bilstein struts are also used. The use of the stabilizer bar reduces body roll.
The GXP’s strong attitude is accentuated with GXP-specific body upgrades. Its new front and rear fascias and rocker extensions highlight the vehicle’s low stance. GXP emblems and prominent exhaust ports on the back fascia hint at the car’s performance potential. A sophisticated and modern interior complements the GXP’s striking design. The inside of the GXP is distinguished with ultraluxe suede inserts for the optional leather seats, brushed aluminum trim details, and a distinctive instrument cluster.
