Powertrain Options and Availability
While model designations for Grand Prix may have changed, the powertrain options did not. Base models had a 200-hp, 3.8-liter V6. A 260-hp supercharged 3.8-liter V6 was standard on GTs. The top-line GXP had a 303-hp 5.3-liter V8. All Grand Prixs used a 4-speed automatic transmission. The mid-level GT trim with its supercharged engine was discontinued for 2008.
