The most important news for the 2008 model year is the availability of the GXP coupe and sedan. They replace the GTP as the performance models and are fitted with GM’s fine 252-hp, 3.6-liter DOHC V-6 mated to a smooth-shifting six-speed automatic transmission with manumatic control. The GXP also features standard leather seats, dual chrome exhaust tips, and more aggressive front and rear fascias and rocker panels.
On the other models, front-seat side airbags, anti-lock brakes, traction control, OnStar, and an auxiliary audio input jack are now standard. GT models now have standard XM satellite radio.
