2021 GMC Canyon II (facelift 2021) Extended cab Dimensions, Size & Specs

The curb weight of the GMC Canyon II Extended Cab ranges from 1783 kg to 1970 kg (3934 to 4341 lbs), while its maximum gross vehicle weight rating (GVWR) spans 2449 kg to 2676 kg (5401 to 5899 lbs). This means it can carry payloads roughly between 479 kg and 903 kg (1056 to 1990 lbs) depending on the variant. Its robust weight capacity supports substantial towing and cargo hauling suited for work and recreational needs.

The GMC Canyon II Extended Cab boasts a ground clearance between 211 mm and 213 mm (8.3 to 8.4 inches), providing excellent underbody clearance for off-road driving and navigating rough terrains. This height allows the vehicle to clear obstacles such as rocks and uneven surfaces while maintaining stability and control.

Standard residential garages typically have dimensions around 2440 mm (8 feet) in width and 2130 mm (7 feet) in height. The GMC Canyon II Extended Cab's width is 1886 mm (74.3 inches or about 6.2 feet), and its height ranges from 1785-1788 mm (about 5.86 to 5.87 feet), so it will comfortably fit within the width and height constraints of a standard garage. The length of 5395 mm (212.4 inches or about 17.5 feet) is also generally considered manageable for typical garage depths, although long trucks may require more clearance to comfortably open rear cargo doors.

Available rim sizes for this GMC Canyon II Extended Cab include 8J x 17 inches and 8.5J x 18 inches. Tire sizes offered are 255/65 R17, 265/65 R17, and 265/60 R18. Larger rims and tires typically enhance grip, road presence, and off-road performance but may slightly reduce fuel efficiency and ride comfort. The tire widths and profiles chosen balance between good on-road handling and off-road capability.

Compared to the previous GMC Canyon generation released before the 2021 facelift, the Canyon II (2021-2022) Extended Cab maintains a similar footprint but with refinements mainly in styling and dimensions for an updated look and improved aerodynamics. While length and width remain close, slight changes in height and ground clearance optimize ride comfort and off-road ability. Overall, the facelift did not drastically alter size but enhanced usability and visual appeal.

The GMC Canyon II Extended Cab sits firmly within the midsize pickup segment, with dimensions comparable to rivals like the Toyota Tacoma, Ford Ranger, and Chevrolet Colorado. Its length of 5395 mm (212.4 inches) and width of 1886 mm (74.3 inches) are near segment averages, offering a balance of maneuverability and utility. The ground clearance of about 211-213 mm (8.3-8.4 inches) is competitive, supporting light off-road use, while its payload and towing capacities also match well with competitors.

The Extended Cab model provides seating for up to four or five passengers, depending on configuration. It features two front bucket seats and a smaller rear bench seat which provides extra room for passengers or cargo inside the cabin compared to the regular cab. While the rear space is tighter than in crew cab variants, it still accommodates occasional rear passengers comfortably for shorter trips, making it a practical choice for those needing extra cabin space without the bulk of a full crew cab.

The Extended Cab configuration strikes a balance between a smaller regular cab and the more spacious crew cab. It offers additional interior storage or passenger room without significantly increasing the vehicle's total size, making it more maneuverable and easier to park. This makes it ideal for buyers who need occasional rear seating or more cabin storage without sacrificing too much cargo bed space. It's versatile for work, family outings, and outdoor activities, providing greater flexibility in size and utility.
