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

The curb weight of the GMC Yukon XL III ranges from 2549 kg (5620 lbs) to 2939 kg (6476 lbs), which reflects the base vehicle weight without passengers or cargo. Its maximum weight, which includes passengers, cargo, and additional equipment, ranges from 3265 kg (7200 lbs) to 3966 kg (8744 lbs). The higher curb weight contributes to a solid and stable ride but can impact fuel economy. The maximum weight capacity indicates that the Yukon XL III is built for robust towing and hauling, able to manage large trailers or heavy loads, which makes it suitable for recreational and professional uses where payload and towing are critical.

The GMC Yukon XL III offers versatile luggage capacity for different needs. With all seats in place, it provides a generous 1297 to 1298 liters (approximately 45.8 cubic feet) of cargo space behind the rear seats. When the rear seats are folded down, the luggage capacity expands dramatically to approximately 3891 liters (137.4 cubic feet), allowing for substantial cargo volume. This flexibility is ideal for large families, road trips, or transporting bulky items, making the Yukon XL III highly practical for a variety of uses.

The GMC Yukon XL III has a ground clearance ranging from 227 mm (8.9 inches) to 236 mm (9.3 inches), depending on specific model and suspension settings. This elevated ride height provides the Yukon XL III with solid off-road capability, allowing it to handle uneven terrain, moderate obstacles, and rural or construction roads with ease. The combination of its SUV design and ground clearance contributes significantly to its versatility, making it capable both on paved highways and off-road trails.

The GMC Yukon XL III comes equipped with a variety of rim sizes including 7.5J x 17, 6.5J x 16, and 18 inches depending on the model trim and package. Corresponding tire sizes include 255/70 R17, 245/75 R16, 265/70 R17, and 265/65 R18. Larger rims and tires, such as the 18-inch setup, tend to improve road handling and cornering stability but may deliver a firmer ride. Smaller tires offer a more cushioned ride and improved off-road traction. This variety allows owners to choose between comfort and sportiness or off-road capability according to their preferences.

Due to its large overall dimensions with a length of 5648 mm (222.4 inches), width up to 2010 mm (79.1 inches), and height nearing 1962 mm (77.2 inches), the GMC Yukon XL III is quite sizable compared to typical vehicles. Most standard residential garages measure approximately 6 meters (20 feet) in length and 2.4 to 2.7 meters (8 to 9 feet) in width, which can present challenges. While the width is generally manageable, the length and height might require special consideration. Owners should verify specific garage dimensions and may need extra clearance or modifications to accommodate this full-size SUV comfortably.

Compared to its predecessor, the GMC Yukon XL II, the Yukon XL III (introduced in 2007) saw various dimensional adjustments that enhanced comfort, space, and capability. The length of the Yukon XL III at 5648 mm (222.4 inches) provided a slight increase in cargo and passenger space, improving overall practicality. Width and height adjustments likewise contributed to a more commanding presence and better interior volume. These dimensional upgrades improved ride comfort, utility, and road presence while maintaining the ruggedness expected of a full-size SUV, making the third generation an evolutionary step that refined and expanded upon the previous model’s strengths.

The GMC Yukon XL III competes directly with other large full-size SUVs like the Chevrolet Suburban, Ford Expedition EL, and Toyota Sequoia. Dimensionally, it is on par or slightly larger in length and width than many peers, with 5648 mm (222.4 inches) in length and up to 2010 mm (79.1 inches) in width. Its robust build, high towing capacity, and large cargo volume make it a leader for families and professionals needing substantial space and performance. Feature-wise, it offers modern amenities for its time, good off-road capability, and a range of V8 engine options. Its size and capability make it a top contender within the full-size SUV segment.

The large size and weight of the GMC Yukon XL III, ranging from 2549 to 2939 kg (5620 to 6476 lbs), inevitably impact its fuel consumption. Full-size SUVs of this era typically exhibit moderate fuel economy, often in the lower range compared to smaller vehicles, due to their heavy weight and large engines designed for power and capability rather than efficiency. This means higher fuel costs for daily driving, especially in urban or stop-and-go traffic. However, the Yukon XL III provides excellent driving comfort and space, making it well-suited for long trips where space compromise is undesirable despite increased fuel use.

The GMC Yukon XL III generally seats seven to nine passengers, depending on configuration, with available three-row seating that offers spacious legroom and headroom due to the vehicle’s length of 5648 mm (222.4 inches) and width of up to 2010 mm (79.1 inches). The third-row seats usually fold down to increase cargo space, allowing for flexible interior configurations that adapt to passenger or luggage needs. The SUV’s large interior dimensions contribute to passenger comfort on long journeys and provide numerous storage compartments, making it an attractive option for families or groups requiring significant seating and cargo space.
