2026 GMC Yukon XL Cargo Space Dimensions AR

The 2026 GMC Yukon XL holds up to 144.5 cubic feet of cargo with the second and third rows folded, and a class-leading 41.5 cubic feet behind a fully raised third row. That is roughly 16 more cubic feet behind the third row than the standard Yukon, enough room to load a weekend of camping gear for Lake Ouachita without folding away a single seat.

For families near Little Rock and Benton who need three rows of real seating and a deep cargo hold at the same time, the long-wheelbase XL is the version built for the job. This guide from Allen Tillery Buick GMC covers the Yukon XL's cargo volumes, exterior footprint, third-row room, and seating flexibility. For the full model picture, start at the 2026 Yukon research hub.

Yukon XL Cargo Volume and Configurations

Cargo space is where the Yukon XL separates itself from the standard Yukon. The numbers below are the maximums for each configuration:

• Up to 144.5 cu. ft. of cargo with the second and third rows folded.
• Up to 93.6 cu. ft. behind the second row, third row folded.
• 41.5 cu. ft. behind the third row with all three rows in use.

That 41.5 cu. ft. behind the raised third row is the figure most families care about, because it is the space you have when every seat is occupied. It is enough for a full grocery run from Bryant or several large suitcases without anyone giving up a seat. A power liftgate is standard, with a hands-free power liftgate available.

How the XL's Size Compares to the Yukon

The Yukon XL is the same vehicle as the standard Yukon from the firewall forward. The extra size lives entirely in the rear of the body, where it benefits the third row and the cargo hold.

• Overall length: 225.2", about 15 inches longer than the 210.1" Yukon.
• Wheelbase: 134.0", roughly 13 inches longer, which is what creates the added room.
• Width: 81.0" without mirrors, and height 76.5" — both shared with the standard Yukon.
• Fuel tank: 28.0 gallons on the XL versus about 24 on the Yukon, for longer range between fill-ups on an I-30 road trip.

One practical note for buyers in Arkadelphia or Hope with older garages: at 225.2" the Yukon XL is close to 18.75 feet long. A typical two-car garage runs about 20 feet (240"), so the XL usually fits, but the margin is tight once you account for a closed door and anything stored at the back wall. Measure your space before you buy.

Third Row and Seating Flexibility

The longer wheelbase gives the Yukon XL 36.7" of third-row legroom, compared with 34.9" in the standard Yukon. That difference of nearly two inches is the line between a third row adults tolerate for short hops and one they are comfortable in on a drive to Lake Ouachita.

• Seating for up to 8 passengers with the second-row bench, or 7 with available second-row captain's chairs.
• Power-folding third-row seats and 60/40 split-folding second and third rows for mixing passengers and cargo.
• Front-row and second-row dimensions are essentially identical to the standard Yukon (about 42 inches of second-row legroom), so the XL adds room without taking any away up front.

Loading, Liftgate, and Cargo Access

Beyond raw volume, the Yukon XL is built to make that space usable. With the second and third rows folded, the load floor opens into a long, near-flat cargo bay that swallows long items most three-row SUVs cannot. The available power-sliding center console can move back up to 10 inches to free additional storage at the front of the cabin.

Yukon XL Space for Arkansas Families

The XL's combination of seats and cargo fits how families across the region actually use a full-size SUV. A camping run to the Ouachita National Forest can carry six or seven people and still hold coolers, tents, and gear behind the third row. Travel teams from Malvern can load a full roster and their bags. And the deep hold behind a folded third row handles furniture and big-box hauls that would otherwise need a trailer. If financing the upgrade matters, you can get pre-approved online before you visit.

Engines, Tech, and Safety: Shared Specs

The Yukon XL shares its powertrains, 10-speed automatic, infotainment, and driver-assistance technology with the standard Yukon, so this page stays focused on what the added length changes. For the rest, see the Yukon engine and performance specs, the technology and safety overview, and the full trim comparison.
