2007 GMC Yukon III (GMT900) Dimensions, Size & Specs

The curb weight of the 2007 GMC Yukon III (GMT900) ranges between 2430 kg and 2805 kg (approximately 5359 to 6184 pounds), depending on trim and options. Its maximum weight capacity spans from 3220 kg to 3409 kg (about 7100 to 7510 pounds), considering passengers, cargo, and towing load. These weights influence handling dynamics, acceleration, braking distances, and fuel consumption. The heavier weight can reduce fuel efficiency and agility but enhances stability and towing capability, making it suitable for large families and heavy-duty tasks.

The 2007 GMC Yukon III provides 478 to 479 liters (approximately 16.9 to 16.9 cubic feet) of luggage capacity when the rear seats are in use. This space is suitable for everyday grocery runs or luggage for a small family. When rear seats are folded down, the available cargo volume expands dramatically to roughly 3084 liters (108.9 cubic feet), creating a vast flat loading floor that can accommodate large items or increased storage needs, making it highly practical for road trips or hauling bulky gear.

Generally, the 2007 GMC Yukon III's dimensions (length 5130 mm / 201.97 inches, width 2007 to 2009 mm / 79.0 to 79.1 inches, height 1927 to 1956 mm / 75.8 to 77.0 inches) should fit into a standard residential garage; however, clearance could be tight depending on the garage size. A standard single-car garage door width is typically around 2.4 to 2.7 meters (94 to 106 inches), which accommodates the vehicle width including mirrors (about 2007 mm / 79 inches). Taller garages or those with high doors are advisable due to the height close to 2 meters. Owners should measure their garage space carefully to ensure comfortable access and egress.

The 2007 GMC Yukon III has a ride height or ground clearance between 227 mm and 229 mm (approximately 8.9 to 9.0 inches), which is relatively generous for a full-size SUV. This clearance enables the Yukon to handle rough terrain, moderate off-road conditions, and obstacles such as rocks or deep ruts without damaging the undercarriage. While it doesn't match specialized off-road vehicles, this ground clearance balances on-road comfort with decent off-road capability, making it suitable for outdoor adventures and unpaved roads.

The 2007 GMC Yukon III offers a variety of rim sizes including 17, 18, and 20 inches with widths such as 7.5J x 17, 8.0J x 18, 8.5J x 20, paired with tire sizes like 265/70 R17, 265/65 R18, and 275/55 R20. Larger rims and tires can enhance road grip, aesthetics, and handling precision but may slightly reduce ride comfort and fuel economy due to increased unsprung weight. The combination chosen affects ride smoothness, cornering stability, and off-road ability, allowing buyers to prioritize performance, comfort, or style according to their preferences.

Compared to its predecessor, the Yukon II (GMT800), the 2007 GMC Yukon III (GMT900) saw increases in length, width, and height. The third generation measures 5130 mm in length, an increase that translates to more interior space and cargo capacity. The width and height also grew modestly, enhancing both road presence and passenger comfort. These dimensional upgrades improved interior volume and stability while maintaining manageable exterior size for maneuverability. Overall, the GMT900 represented an evolution favoring spaciousness and modern amenities over the more compact previous generation.

When compared to similar full-size SUVs like the Ford Expedition, Chevrolet Tahoe, and Toyota Sequoia, the 2007 GMC Yukon III is competitive in length and width, offering robust interior space and cargo capacity. Its length of 5130 mm (201.97 inches) is on par with many rivals, although some competitors might be slightly longer or wider. The Yukon often balances generous passenger and cargo volume with a relatively high ground clearance and curb weight range. Buyers choosing between these SUVs will find the Yukon stands out for its luxurious appointments and towing capability, while dimensionally fitting well into the large SUV category.

The curb weight of 2430 to 2805 kg (5359 to 6184 lbs) and maximum weight between 3220 and 3409 kg (7100 to 7510 lbs) directly influence towing capacity, fuel economy, and vehicle handling. Heavier weight generally allows the Yukon III to tow larger trailers and carry more payload safely, an essential feature for users needing to haul boats, campers, or heavy equipment. However, increased weight typically results in higher fuel consumption and can slightly diminish acceleration. The Yukon III strikes a balance, offering a robust towing capability while maintaining reasonable efficiency for a vehicle of its class.

The 2007 GMC Yukon III generation marked a significant redesign with improvements in styling, interior quality, and technology. It introduced a more modern and muscular exterior, enhanced safety features, and a more refined suspension system for better ride comfort. The interior was upgraded with advanced infotainment options and increased passenger comfort through more spacious seating and improved materials. Powertrain options in this generation were also enhanced to improve performance and fuel efficiency. These improvements positioned the Yukon III as a competitive luxury full-size SUV appealing to families and towing enthusiasts alike.
