2026 GMC Yukon XL For Sale


View Yukon XL Inventory Get Pre-Approved Schedule Test Drive

The 2026 GMC Yukon XL is the largest SUV GMC builds: the extended-length sibling to the standard Yukon, made for drivers who want maximum third-row room and cargo space without giving up full-size capability. At 225.2 inches long on a 134-inch wheelbase, it stretches 15.1 inches beyond the standard Yukon, and almost all of that added length sits behind the rear axle where third-row legroom and cargo room actually live.

For families across central Arkansas who regularly carry seven or eight passengers and their gear, the XL is the size that fits, from a weekend at Lake Ouachita to a long highway run to Little Rock and back. It seats up to 8 and opens up to 144.5 cubic feet of cargo with the rear seats folded, the most of any GMC SUV. For the full picture of the family, start from our 2026 GMC Yukon research hub.

Yukon XL vs. Standard Yukon: Which Size Fits

The Yukon and Yukon XL share the same trims, engines, technology, and safety equipment. The only meaningful differences are length and the space that length creates. Choose the XL when third-row passengers ride often, when you need cargo room behind a full set of seats, or when you tow with the whole family aboard. Choose the standard Yukon if a tighter footprint matters more for parking and a tight garage. For a complete side-by-side on length, wheelbase, cargo, and price, see our Yukon vs Yukon XL comparison.

Size, Seating, and Cargo

The Yukon XL measures 225.2 inches long on a 134-inch wheelbase and seats up to 8 passengers, or 7 with available second-row captain's chairs. Maximum cargo space reaches 144.5 cubic feet with the rear seats folded. The extended body also adds room behind the third row versus the standard Yukon, so you can seat a full third row and still load luggage underneath. For the complete dimension and cargo breakdown by row, see the Yukon XL cargo and dimensions page.

Trims, Engines, and Technology

The Yukon XL comes in five trims, identical to the standard Yukon: Elevation, AT4, AT4 Ultimate, Denali, and Denali Ultimate. Pricing runs from about $75,400 MSRP on the Elevation to roughly $109,700 on the Denali Ultimate. The full trim-by-trim breakdown and pricing lives on the 2026 Yukon trims and pricing page.

Three powertrains carry over to the XL unchanged, each paired with a 10-speed automatic: the 5.3L V8, the naturally aspirated 6.2L V8, and the available Duramax 3.0L Turbo-Diesel I6. Only the Duramax is turbocharged; both V8s are naturally aspirated. Properly equipped, the Yukon family tows up to 8,400 lbs (per GMC). For horsepower, torque, MPG, and tow ratings by engine, see the engines and performance page.

On the technology side, the XL offers available Super Cruise hands-free driver assistance, a 16.8-inch infotainment touchscreen, HD Surround Vision, and GMC's suite of standard and available driver-assist features. Those details live on the technology and safety page.
