Big, brash, packed full of technology, powered by a Cadillac Northstar engine with front-wheel-drive and 4-speed auto. The GXP is Pontiac's flat-out performance version of its senior sedan. But, we wonder, is the Bonneville a car of today or the last of the line? Warranty 3-years, 36,000 miles; base price $35,995.
First Glance
The Bonneville has a distinguished history dating back to 1956. It has always been Pontiac's luxury model, always loaded with features, often powered by the division's most powerful V-8's. Perhaps the Bonneville's greatest years were in the Wide Track era when its width and long, straight silhouette were shown to best advantage. Or some might say the more recent SSEi epitomised the Bonneville's character. Certainly the 2004 GXP has all the elements needed to define this legendary name in a contemporary, very-wedge package. The former supercharged V-6 has been replaced with a Northstar V-8; a performance-tuned suspension deals nicely with the added power and larger disc brakes can slow it down in a hurry. What really sets the 2004 Pontiac Bonneville apart, however, is the extensive amount of technology packed into its aggressive-looking shape, in particular the way this is reflected by the busy interior. A fairly recent restyling sets the mode for future Pontiac design, yet we wonder if the age of the wedge may be coming to an end.In the Driver's Seat

On the Road
The first thing I noticed upon driving away is the car's size. It's big and feels even bigger because the driver has no idea where the extremities lie. There's a heaviness to the way it responds; for example Pontiac claims a 0-60 time of just over six seconds yet acceleration feels slower. Like a 300-pound lineman the Bonneville seems to gather up its energy before charging. (Hard not to like the burble of the 275 hp 4-cam Northstar V-8, though.) The electro-magnetic steering seems fairly responsive but lacks road feel and the turning circle is rather large. Roadholding is quite remarkable for a car in which the engine sits entirely ahead of its front axle but Pontiac's engineers have always excelled at suspension tuning; the StabiliTrac system helps avoid skids and traction control maintains the straight-and-narrow. 18" aluminum wheels reveal massive disc brakes with calipers highlighted in red (that just happened to match the color of our test car). Expressway cruising, however, is where the Bonneville excels, particularly on curving Appalachian runs or through the mountains of Vermont. And if you're stuck in traffic, well, there's always that 8-speaker Monsoon sound system to keep you amused.Journey's End
