The Standard Yukon: A Premium Fortress
The standard Yukon is a premium family fortress built perfectly for the realities of Minnesota driving. By folding both rear rows completely flat, drivers reveal a massive 122.9 cubic feet of volume. Even when all seats are upright, you still have an impressive 25.5 cubic feet of space behind the third row.
This footprint is often preferred by drivers who want heavy-duty truck strength but require slightly easier parking maneuverability during the daily commute in Mower County.
The Yukon XL: Maximum Cargo Expansion
If your lifestyle demands major hauling tasks, stepping up to the extended-wheelbase Yukon XL provides the ultimate solution. This model stretches the vehicle's rear footprint to expand that maximum cargo space to an incredible 144.7 cubic feet.
This XL configuration is ideal for transporting a large family across the Midwest without sacrificing any luggage capacity for long weekend trips up to northern Minnesota. You can compare the precise exterior length dimensions of both wheelbase options on the official GMC full-size SUV page.
