2004 GMC Canyon I Extended cab Dimensions, Size & Specs

The curb weight of the GMC Canyon I Extended Cab ranges from 1521 kg to 1876 kg (3352 to 4137 lbs), depending on the engine variant, trim level, and optional equipment. The maximum permissible weight, or Gross Vehicle Weight Rating (GVWR), is between 2268 kg and 2404 kg (5000 to 5300 lbs). This weight capacity allows the truck to carry moderate payloads and tow trailers, making it versatile for work and recreational activities.

The luggage or cargo volume for the GMC Canyon I Extended Cab is approximately 1243 to 1245 liters (about 44 cubic feet). This space includes the cargo bed, which is typical for a pickup truck of this size. While the cab area offers passenger seating, cargo is primarily handled in the rear bed, suitable for carrying tools, equipment, or recreational gear. The extended cab configuration also provides extra interior storage space compared to regular cab models.

The GMC Canyon I Extended Cab's ground clearance ranges from 167 mm to 290 mm (6.6 to 11.4 inches), depending on the suspension setup and tire options. Higher ride height models are typically designed for off-road use, providing better capability over rough terrain, while models with lower ground clearance may favor on-road handling and stability. This range offers flexibility to owners based on their driving preferences and requirements.

The GMC Canyon I Extended Cab offers a variety of rim and tire sizes to suit different performance needs. Rim sizes include 6J x 15, 6.5J x 15, 15 inches, 17 inches, and 18 inches. The compatible tire sizes are 205/75 R15, 225/70 R15, 235/75 R15, 235/50 R18, and 265/70 R17. These options allow drivers to customize the truck for better off-road traction, improved road handling, or enhanced aesthetics.

With an overall length of 5260 mm (207.1 inches), width up to 1742 mm (68.5 inches), and height up to 1723 mm (67.8 inches), the GMC Canyon I Extended Cab generally fits within standard residential garages, which usually measure around 6000 mm (20 feet) in length and 3000 mm (10 feet) in width. However, tighter garages or those with storage items on the sides may present challenges. Owners should measure their garage space carefully before parking the Canyon I Extended Cab inside.

The GMC Canyon was introduced in 2004 as a replacement for the GMC S-15 and Sonoma pickup trucks, which were smaller compact pickups. The Canyon I Extended Cab features increased dimensions versus these predecessors, offering a longer length of 5260 mm compared to earlier models that were approximately 4500 mm long, wider stances, and greater height, providing improved cabin space, better cargo capabilities, and enhanced ride comfort. This generation marked GMC's shift toward a mid-size pickup segment with more versatility.

Compared to similar mid-size pickups from the 2004-2012 era, such as the Toyota Tacoma, Nissan Frontier, and Ford Ranger, the GMC Canyon I Extended Cab stands out with a length of 5260 mm (207.1 in), which is slightly longer than most competitors. Its width of about 1717-1742 mm (67.6-68.5 in) is comparable to these trucks, while the height range makes it versatile across different trims. Overall, the Canyon offers a competitive size profile that balances passenger comfort with cargo capability.

The GMC Canyon I Extended Cab typically seats up to four passengers, featuring two standard front seats and a smaller rear jump seat accessed by rear-hinged half doors. Its extended cab design provides more room than a regular cab but less than a crew cab. Interior space is optimized for work and short trips rather than long-distance comfort, with adequate headroom and legroom for front passengers but limited space in the rear due to the design focus.

Owners of the GMC Canyon I Extended Cab should note its larger size compared to compact pickups, especially the length of over 5 meters (207 inches). This affects maneuverability in tight urban parking areas, garages, or narrow driveways. The width approaching 1.75 meters (68.5 inches) means some parking spaces can be a tight fit, and clearance height under garages or low-hanging obstacles should be checked, given the height up to 1.72 meters (67.8 inches). Ground clearance variations may also affect ramp access or loading docks.
