The 2007 Pontiac Grand Prix is available in three trim levels. The base sedan, which has a starting MSRP of $22,500, has a 200 horsepower, 3.8 liter V6 engine, and the GT (starting at $25,420) has the same engine, kicked up to 260 horsepower. For a base MSRP of $29,500 the GXP comes with a 303 horsepower, 5.3 liter V8 engine, that also has electronic throttle control. There are two available transmissions: a four-speed automatic, or a TAPshift transmission that allows manual gear shifting.

Estimated fuel efficiency is 20 mpg city and 30 highway with the 3.8 liter; 19/28 with the supercharged version; and 18/27 with the 5.3 liter. (Fuel capacity is 17 gallons.) Crash avoidance features include a four-wheel antilock braking system as well as an enhanced traction control system, and a system that monitors tire pressure. Daytime running lights, fog lights, and high intensity halogen headlights are other options that vary by trim level.

Security features include automatic door locks, keyless entry, and an electronic anti-theft system, as well as emergency trunk release handle. The 2007 Grand Prix comes with multi-stage front airbags, as well as head-protecting side-impact airbags for both the front and back seats. Safety-cage construction, three-point seat belts for all passengers, and the LATCH system for child seats round out the standard features.
