What Changed for 2008:
  • GT model dropped

  • Standard OnStar

  • Standard tire-pressure-monitoring system

The 2008 midsize, front-wheel-drive Pontiac Grand Prix, which shares the same platform as the Chevy Impala, while mostly carryover from 2007, adds standard OnStar and tire-pressure monitors and three new colors. Last revised in 2004, the Grand Prix's design may seem a bit dated, but there's still plenty of torque in the GXP, reminiscent of muscle cars of days past. Pontiac drops the GT model for 2008.

Model Lineup
For 2008, the Pontiac Grand Prix comes in the base sedan and more powerful GXP models. Eight packages are available to option up the base; one of those is available for the more content-equipped GXP. Standard equipment on both models includes front bucket seats; 6-way power driver seat; tilt and adjustable steering column; remote keyless entry; power windows and door locks; AM/FM stereo with CD player; and body-color, body-side molding. The GXP adds a more powerful V-8 engine; fog lamps; performance-tuned suspension; tire inflation kit; heated front seats; 2-way power driver lumbar controls; dual-zone air conditioning; leather-wrapped steering wheel; Monsoon 9-speaker system; remote vehicle starting; head-up display; cargo net; interior chrome accents; dual chrome tip exhaust; front and rear body-color fascias; and a rear sport spoiler.

Stand-alone options available on the 2008 Pontiac Grand Prix include fog lamps; rear sport spoiler; custom grille inserts; trunk mat; power sunroof; heated front seats; overhead console; and traction control. A Special Edition package available on the base model includes 17-inch aluminum wheels, stainless-steel dual exhaust, body-color grille, front and rear fascias, and side rocker panels.

The base 2008 Pontiac Grand Prix sedan is powered by a 3.8-liter V-6 engine with electronic throttle control that produces 200 hp at 5200 rpm and 230 lb.-ft. of torque at 4000 rpm. The GXP gets a 5.3-liter V-8 engine with active fuel management, delivering 303 hp at 5600 rpm and 323 lb.-ft. of torque at 4400 rpm. A 4-speed electronically controlled automatic transmission with overdrive transfers the power for both engines. EPA fuel-economy estimates for the V-6 engine are 18 mpg city/28 mpg highway, while the V-8 engine gets 16 mpg city/25 mpg highway. Stability and traction control and 4-wheel ABS are standard on GXP, with all but stability control available on the base Grand Prix.

According to the National Highway Traffic Safety Administration (NHTSA), the Pontiac Grand Prix receives a best-possible 5-star rating for the driver and a 4-star rating for front passenger in frontal crash tests, and a 3-star safety rating for front and rear passengers in side-impact tests. In NHTSA rollover testing, the Grand Prix receives a 4-star rating.

While the standard audio system for the base and GXP Grand Prix models is an AM/FM stereo with CD player, optional audio systems include a 6-disc, in-dash CD changer with Monsoon premium 9-speaker system; an AM/FM stereo with CD/MP3 player; and an audio system with navigation.
