2021 GMC Yukon XL V Dimensions, Size & Specs

The luggage capacity of the 2021 GMC Yukon XL V reflects its utility and versatility. With all seats upright, it provides 1175 liters (41.5 cubic feet) of cargo space, ample for everyday needs, groceries, or luggage for road trips. When the rear seats are folded down, this space expands significantly to 4097 liters (144.7 cubic feet), offering one of the most generous cargo holds in its segment. This flexibility makes the Yukon XL V ideal not only for passenger transport but also for moving large or bulky items, making it a practical choice for adventure and family use.

Given the 2021 GMC Yukon XL V's dimensions—5721 mm (225.2 inches) in length, 2058 mm (81.0 inches) in width, and 1943 mm (76.5 inches) in height—fitting it into a standard residential garage can be challenging. Most single-car garages are typically about 6 meters (20 feet) deep and 3 meters (10 feet) wide, which leaves very little room, especially in length and width for maneuvering or opening doors fully. Homeowners with standard garage dimensions may find it tight or impractical without modifications, making the Yukon XL more suited to larger garages or dedicated parking spaces. Buyers should check their local garage measurements and consider this before purchasing.

Compared to its predecessor, the 2021 GMC Yukon XL V has maintained a similar footprint but with subtle refinements to optimize space and comfort. The length remains close to the previous generation’s, ensuring the extended XL variant preserves its hallmark spaciousness. While exact predecessor dimensions vary by model year, the current generation slightly enhances width and height for improved interior room and design styling. The cargo area has also been optimized for usability, particularly with the rear seats folded to bolster luggage capacity. Overall, the 2021 Yukon XL V builds on its predecessor’s legacy by improving interior dimensions and utility without significantly altering the exterior size.

The 2021 GMC Yukon XL V offers a range of rim sizes—18, 20, and 22 inches—which provide versatility for different driving preferences. Tires sized 265/65 R18, 275/65 R20, 275/60 R20, and 275/50 R22 correspond to these rims. The larger 22-inch rims wrapped with lower-profile 275/50 tires enhance road grip and styling, especially on highways and city streets, but may slightly reduce ride comfort over rough terrain. The 18-inch rims with taller sidewall tires (265/65) better absorb bumps and provide a cushier off-road capability, improving durability and ride comfort. The 20-inch options offer a balanced compromise of style, handling, and comfort. Overall, these options allow drivers to tailor the Yukon XL V’s driving dynamics according to their priorities—whether comfort, sportiness, or off-road readiness.

The 2021 GMC Yukon XL V provides a spacious interior that comfortably seats up to eight passengers, making it perfect for large families or group travel. Its extended wheelbase offers increased legroom, especially in the second and third rows, compared to the standard Yukon. The roomy cabin is designed for passenger comfort on long trips with generous headroom, shoulder room, and ergonomic seating. The flexibility of its seating configurations enables a blend of passenger and cargo needs, with easily foldable rear seats to maximize usable space. High-end materials and advanced technology options enhance the overall comfort and utility of the cabin.

Among full-size SUVs, the 2021 GMC Yukon XL V ranks as one of the larger and more capacious models. Its length of 5721 mm (225.2 inches) surpasses many competitors, such as the Chevrolet Tahoe and Ford Expedition, especially in cargo space with rear seats folded—offering an impressive 4097 liters (144.7 cubic feet) of luggage capacity. The wide and tall body ensures substantial passenger room and headspace, competing strongly in the segment for comfort and utility. The Yukon XL’s extensive cargo volume and seating flexibility often place it ahead of rivals, making it a top choice for those needing maximum passenger and cargo capacity combined with premium features.

Since its launch in 2020 and continuing production through the present, the GMC Yukon XL V has maintained consistent exterior dimensions without significant changes. The 5721 mm (225.2 inches) length, 2058 mm (81 inches) width, and 1943 mm (76.5 inches) height remain standard throughout this generation, ensuring that buyers get a consistent size experience regardless of the specific model year within this production run. Any updates tend to focus on technology, trim levels, and mechanical improvements rather than dimensional alterations.

The curb weight of the GMC Yukon XL V typically ranges from approximately 2650 to 2900 kilograms (5840 to 6395 pounds), depending on trim and optional equipment. This substantial weight reflects its robust construction, large frame, luxury features, and safety equipment. While the heavy mass contributes to a solid, stable driving experience with a commanding road presence, it also impacts acceleration and fuel economy. Heavier weight usually leads to higher fuel consumption, which is typical for full-size SUVs in this segment. Innovations in engine technology and drivetrain options aim to optimize performance, but prospective buyers should balance the vehicle's weight advantages with their expectations for fuel efficiency.

The 2021 GMC Yukon XL V is designed primarily as a large luxury SUV with some off-road capability, particularly when equipped with the appropriate 4WD system and off-road packages. Its size and weight, however, mean it is less nimble off-road than smaller SUVs or dedicated off-road vehicles. The vehicle's height (1943 mm or 76.5 inches) provides reasonable ground clearance for moderate off-road terrain, but its long length (5721 mm or 225.2 inches) can pose challenges on tight trails or uneven surfaces, limiting maneuverability. Rims and tires can also be selected to improve off-road traction, but the Yukon XL V is best suited for mild to moderate off-road use combined with premium comfort and towing capacity.
