2004 Pontiac Bonneville Review

A sedan billed as “Luxury with Attitude.?

Reviewed by Automotive on


The 2004 Pontiac Bonneville originally carried the slogan “Luxury with Attitude,? which consumers have dubbed an extremely accurate description, given its basis on Cadillac’s Seville platform and its optional 275 horsepower Northstar V-8 engine. The Bonneville classifies as a large sedan packed with performance and features, but it remains consistent with traditional Pontiac styling.

This year, the Pontiac Bonneville comes in a new Model known as the GXP, the V-8 engine powered option. It marks the most performance-oriented option by far and remains a consumer favorite.

The Range

Body Styles: sedan
Engines: 3.8-liter V-6, 4.6-liter V-8
Transmissions: four-speed automatic
Models: Pontiac Bonneville SE, Pontiac Bonneville SLE, Pontiac Bonneville GXP

What's New

Although Pontiac no longer offers its supercharged SSEi version of its luxury touring vehicle it now offers a V-8-powered GXP making its debut in 2004. The GXP provides the most performance-oriented Bonneville. It features more streamlined styling and comes with 18-inch wheels, a sport-tuned suspension, a Monsoon sound system, and leather and suede seats. Aside from this model, the 2004 Pontiac Bonneville offers minimal new features. Chrome wheels provide an option for the SE. The Bonneville looks a newer, with sportier styling, and XM Satellite Radio comes as an option.


The Bonneville comes in many exterior colors, adding red, blue, and blue ice metallic to the classic variations of black, white, and silver. The 2004 Pontiac Bonneville features 16-inch steel wheels with full wheel covers, all-season tires, as well as an inside-mounted spare tire. The 2004 Pontiac Bonneville measures out to a 74.2-inch width, a 56.6-inch height, and a 202.6-inch length. It has a curb weight of 3633 pounds and a ground clearance of 5.4 inches. Its front track measures 62.6 inches, the rear track stands at 62.1 inches, and its wheelbase totals 112.2 inches. The Bonneville offers a maximum cargo capacity of 18 cubic feet, and a maximum towing capacity of an impressive 1000 pounds.


The interior of the 2004 Pontiac Bonneville includes many convenience and comfort features but starts with the basics. It features cloth bucket front seats and feels quite spacious in both the front and the rear. In addition to many cup holders, overhead storage, and remote trunk release, the Bonneville also features cruise control, dual illuminating vanity mirrors, and an AM/FM/CD stereo with six speakers. The seating comes in two colors: dark pewter or taupe.

Performance & Handling

The 2004 Pontiac Bonneville contains a 3.8-liter V-6 engine, which delivers 205 horsepower at 5200 rpm and 230 lb-ft of torque at 4000 rpm. Its base engine uses gas, and it has a turning radius of 40.5 feet. The 4.6-liter V-8 engine delivers an impressive 275 horsepower. The vehicle features four-wheel ABS, as well as four disc brakes including two ventilated discs. It offers an independent strut front suspension with a stabilizer bar and coil springs, as well as a trailing arm rear suspension, also independent with coil springs. Automatic rear suspension leveling improves the ride. The Bonneville has long been considered a fine road car, and it delivers a strong performance. Handling on the Bonneville doesn’t particularly stand out. Most models have light steering and respond well to driver inputs. It experiences noticeable body roll during quick curves, but nothing drastic. Overall, this Bonneville rides comfortably and offers an easy drive.


The Pontiac Bonneville includes many safety and security features, ranging from the usual four-wheel ABS all the way to the luxurious remote anti-theft alarm system. Some other features include daytime running lights, an engine immobilizer, electronic brake force distribution, and emergency interior trunk release. The NHTSA ratings of the 2004 Pontiac Bonneville reach five stars for driver, four stars for passenger, four stars for side-impact front, four stars for side-impact rear, and five stars for rollover tests. For the IIHS, the Bonneville earns a rating of “Good? in the frontal-offset test, but a rating of “Poor? (the lowest rating) in rear crash protection and head restraint. As the IIHS tests more than occupant injury and instead focuses on how the vehicle structure performs, the ratings do not correlate to a chance of injury.
