Pontiac Bonneville has been delivering driving excitement and total comfort to owners since the 1950s. For 2004, Bonneville receives an all-new performance model, the GXP. Available in early 2004. It comes with refined styling (including new fascias, headlamps, taillamps, exhaust tips and a spoiler), more horsepower, and an upgraded interior. It was designed and engineered to deliver brute power on-call but with the ability to cruise from California to Florida in comfort. The GXP features an aluminum 4.6L DOHC 32-valve V-8 engine that kicks out 275 horsepower (205 kw) and 300 lb.-ft. (224 Nm) of torque - enough to pass without even breathing hard. And when the throttle opens up, the performance-tuned dual exhausts let out a pleasing rumble, letting the driver know just where the power is coming from. The GXP's performance-tuned handling package includes a revised four-wheel independent suspension, StabiliTrak electronic stability system and an electronically controlled transaxle with a 3.71 final drive gear. Stopping power is handled by large four-wheel anti-lock disc brakes. Pontiac also has mounted 18-inch V-rated performance tires on stylish aluminum wheels, providing tenacious grip through the corners. New suede inserts adorn the seats and door panels; the shift handle is brushed aluminum; carbon-fiber trim is abundant and the interior switchgear is a rich ebony. Standard memory bucket seats on the GXP model include power lumbar and power recliner controls on the driver's seat. The GXP includes a center console storage with rear heating/cooling outlets. Driver and front-passenger side-impact air bags and dual-zone climate control with individual climate settings for the driver and front passenger are standard with this top-of-the-line model. A CD player and Monsoon eight-speaker sound system rivaling many great home systems also are a part of the GXP.
