2006 Pontiac Grand Prix Trims and Specs

The sporty mid-size sedan is left virtually untouched for 2006. The Pontiac Grand Prix Base comes with a 3.8-liter, 200-hp V6 engine and 4-speed auto tran and sits on 16-inch all-season tires. A rear spoiler, dual front airbags and daytime running lights are standard, but you'll pay more for ABS brakes, traction control, head airbags, a tire monitor, and foglights.

But the 2006 Grand Prix Base is still well equipped with power windows, doors, and locks, OnStar, a Driver Information Center, tachometer, cruise control, air conditioning, and a radio data readout. Rear seats split-fold to increase trunk size to 57 cubic feet. Options add a CD-changer, sunroof, heated seats, new perforated leather shifter and wheel trim, satellite radio, remote start, a trip computer, navigation system, and 17-inch tires. A Special Edition pack adds ground effects and bright exhaust tips. Drivers of the 2006 Grand Prix say it's a sporty, yet smooth ride, and the V6 engine has plenty of power. A cramped backseat is made for kids rather than adults, and cheap plastic mars the interior.

The 2006 Pontiac Grand Prix GT sedan brings back some sports performance to the lineup with a supercharged 3800 V6 that hits 260-hp, matched with a 4-speed automatic transmission. The GT adds ABS brakes, traction control, a tire monitor, and foglights to its standard equipment, along with dual front and side airbags. A rear spoiler and 17-inch tires adorn the exterior. Rear seats split-fold to expand the trunk in the five-passenger sedan.

The 2006 Grand Prix GT also has a security system and a power driver's seat with power lumbar support, both upgrades to the base model. Other additions include leather trim on the shifter and wheel and wheel-mounted audio controls. Power features, keyless entry, OnStar, a CD player, and cruise control are also standard. Extras include satellite radio, a navigation system, sunroof, CD-changer with MP3, heated leather seats, dual-zone climate control, and head airbags. A Sport Package tacks on 17-inch alloy wheels, ground effects, and bright exhaust tips. Owners mention the supercharged engine and acceleration power as a high point of owning a 2006 Grand Prix GT. They wish it had a manual transmission and that the backseat was bigger.

The Pontiac V8 combo is back in the 2006 Pontiac Grand Prix GXP, a 303-hp, 5.3-liter V8 sport sedan that offers a bit of family practicality and personal fun in one package. Paired with a 4-speed auto tran only, the 2006 Grand Prix GXP sits on larger 18-inch alloy wheels and performance tires, and comes with the full complement of ABS brakes, traction control, and stability control. Dual front and side airbags, a tire monitor, foglights, and daytime running lights are also standard. The GXP also features the unique heads-up display, which projects car information onto the windshield so you don't have to take your eyes off the road.

Another feature beyond what you find on the GT are TAP shift paddles on the steering wheel. The 2006 Grand Prix GXP also has leather seats, an 8-way power driver's seat, a trip computer, cruise control, OnStar, CD player, full power accessories, keyless entry, and leather trim. The Sport Package is not offered with the GXP, but some options include heated seats, head airbags, a CD changer with MP3 playback, satellite radio, a navigation system, sunroof, and dual-zone climate control. On the GXP, you can also get leather seats with suede inserts. Drivers say the GXP has great power, a smooth ride, and superior handling, along with subtle sporty looks. The heads-up display is a big hit. They complain that the backseat is too small, the interior has too much plastic, and they always want a little more power.
