2004 Pontiac GTO Dimensions, Size & Specs

The curb weight of the Pontiac GTO produced between 2004 and 2006 ranges from approximately 1650 kg to 1720 kg (around 3638 to 3794 pounds). This weight reflects the car’s robust build, performance components, and the muscle car characteristics that contribute to its powerful driving dynamics.

The 2004-2006 Pontiac GTO provides a luggage capacity of about 370 liters (roughly 13.1 cubic feet). This capacity is decent for a coupe with performance focus, allowing room for a couple of medium-sized suitcases or several smaller bags, making it practical for weekend trips and daily use.

The Pontiac GTO of this generation typically comes equipped with 18-inch rims. The tire sizes are 235/40 R18 on the front and 245/45 R17 on the rear. These tire sizes contribute to the car's handling precision and road grip, enhancing its performance muscle car characteristics.

Yes, the 2004-2006 Pontiac GTO, with its length of 4800 mm (189 inches), width of 1840 mm (72.4 inches), and height of 1400 mm (55.1 inches), will generally fit comfortably into a standard residential garage. Most standard garages accommodate vehicles roughly up to 5200 mm (204 inches) in length and 2400 mm (94.5 inches) in width, so this coupe poses no unusual challenges in parking spaces for typical homes.

The 2004 Pontiac GTO is notably larger and more modern in dimensions than the classic 1960s-70s GTO models, which were generally smaller in length (usually around 4800 mm but narrower and sometimes taller). While the classic GTOs had a more compact muscle car size, the 2004 model incorporates contemporary design with slightly increased width and refined aerodynamics, resulting in a more stable ride and updated luxury features while maintaining the muscle car essence.

In comparison to similar muscle coupes from the mid-2000s such as the Ford Mustang and Chevrolet Camaro, the Pontiac GTO is competitively sized. For instance, it is very close in length and width to the fifth-generation Ford Mustang, though slightly lower in height. Its luggage capacity and overall weight also put it in a similar category, making it a direct competitor in the muscle coupe segment with a balance of performance and usability.

While specific interior dimensions such as legroom and headroom may vary slightly, the Pontiac GTO maintains a driver-focused cockpit typical of a coupe. Passenger space is optimized for two front seats with decent rear seating for occasional passengers; however, rear seat space is more suitable for short trips or smaller passengers. The car’s width of 1840 mm (72.4 inches) provides enough shoulder room to comfortably accommodate adults in front.

A height of 1400 mm (55.1 inches) is typical for muscle coupes like the Pontiac GTO from the mid-2000s, contributing to a low center of gravity which enhances handling and stability during spirited driving. This relatively low stance helps improve aerodynamics and road feel, offering the driver a sportier experience without compromising comfort.

The Pontiac GTO’s use of 18-inch rims with front tires sized at 235/40 R18 and rear tires at 245/45 R17 is an important factor in its performance. The relatively wide tires provide enhanced grip and traction, essential for a muscle car’s powerful rear-wheel-drive setup. This configuration improves cornering stability, braking performance, and overall handling, while the staggered tire sizes help in balancing front-to-rear weight distribution and driving dynamics.
