More Room for Everyone’s Plans: 2027 Yukon XL

2027 GMC Yukon XL: The Extended GMC SUV for Passenger-and-Cargo Days

The 2027 GMC Yukon XL is a full-size, three-row SUV built for people who need room for passengers and their belongings at the same time. The extended-length member of the Yukon family adds space behind the third row compared with the standard Yukon, while retaining the lineup’s combination of V8 or diesel power and premium appointments.

For shoppers comparing large SUVs for families in Shillington, PA, the Yukon XL offers five trims: Elevation, AT4, AT4 Ultimate, Denali, and Denali Ultimate. Explore new GMC models at Geoff Penske GMC and ask about Yukon XL availability.

Interior Specs and Features

The Yukon XL cabin keeps three rows useful without leaving the luggage behind. Flexible seating adapts as the passenger count changes.

Interior Dimensions

• Seating: Up to eight with a second-row bench or seven with second-row bucket seats
• Legroom: 44.5 inches in front, 42.0 inches in the second row, and 36.7 inches in the third row
• Headroom without a sunroof: 42.3 inches in front, 38.9 inches in the second row, and 38.2 inches in the third row
• Cargo volume: 41.5 cubic feet behind the third row, 93.6 cubic feet behind the second row, and 144.5 cubic feet behind the first row

Bags can travel behind the upright third row without requiring passengers to give up a seat. Fold the rear seating when larger cargo takes priority.

Interior Highlights

• Seating layouts: Standard second-row bench on Elevation and AT4, with available bucket seats; standard bucket seats on Denali and Ultimate trims, with a bench available on qualifying Denali configurations
• Everyday comfort: Standard heated front and second-row outboard seats, a heated steering wheel, and tri-zone automatic climate control
• Front-seat ventilation: Standard on AT4 and higher trims; available on Elevation
• Premium seating: Full-grain leather and front-seat massage on AT4 Ultimate and Denali Ultimate
• Child-seat accommodations: Second-row lower anchors and top tethers, plus third-row top tethers

A bench prioritizes capacity, while separate second-row seats give occupants their own space. Try your usual child seats when comparing layouts.

Exterior Design

Long proportions give the Yukon XL its extended-cabin utility and a substantial presence on the road. Trim-specific details shift its appearance from the rugged AT4 family to the more polished Denali models.

Exterior Dimensions

• Overall length: 225.2 inches
• Wheelbase: 134 inches
• Width without mirrors: 81 inches
• Height: 76.5 inches
• Turning diameter: 43.3 feet curb to curb with 20- or 22-inch wheels; 44.7 feet with 24-inch wheels on 4WD models

Measure your garage before bringing the XL home. The turning diameter also matters in tight lots and narrow driveways.

Exterior Highlights

• Lighting and mirrors: Standard LED headlights and taillights, plus heated, power-folding outside mirrors
• Wheels: Standard 20-inch wheels on Elevation, AT4, AT4 Ultimate, and Denali; 24-inch wheels on Denali Ultimate
• AT4 equipment: All-terrain tires, a front skid plate, and red recovery hooks
• Liftgate: A power programmable liftgate on Elevation and an AutoSense hands-free power liftgate on the other trims
• Assist steps: Power-retractable steps with perimeter lighting on the Ultimate trims

The available hands-free liftgate can simplify loading when your hands are full, while the AT4 hardware supports travel beyond paved roads. The XL’s extended wheelbase still calls for careful route selection on uneven terrain.

Exterior Paint Options

• Coastal Dune
• Glacier White Tricoat
• Titanium Rush Metallic
• Summit White
• Onyx Black
• Volcanic Red Tintcoat
• Sterling Metallic
• Downpour Metallic

Coastal Dune is limited to AT4 and AT4 Ultimate, while Glacier White Tricoat is limited to Denali and Denali Ultimate. Downpour Metallic is not available on the AT4 trims. Other color and interior combinations may be restricted, and some finishes carry an extra charge.

Power and Performance

Three engines offer different approaches to highway travel, passenger loads, and trailering. Compare the complete configuration rather than horsepower alone.

Engines and Powertrains

• 5.3-liter V8: 355 horsepower and 383 lb-ft of torque; standard on Elevation and AT4
• 6.2-liter V8: 420 horsepower and 460 lb-ft of torque; available on AT4 and standard on AT4 Ultimate, Denali, and Denali Ultimate
• Duramax® 3.0-liter turbo-diesel: 305 horsepower and 495 lb-ft of torque; available across the lineup, with required packages on Elevation, AT4, and Denali

The diesel leads in torque, while the 6.2-liter V8 leads in horsepower. Consider your typical load and intended trailer when choosing.

Transmission and Drivetrain

• Transmission: 10-speed automatic with each engine
• Drivetrain choices: Rear-wheel drive or available four-wheel drive on Elevation and Denali; standard four-wheel drive on AT4, AT4 Ultimate, and Denali Ultimate
• Transfer case: Two-speed unit on AT4 trims and Denali Ultimate; available on other 4WD configurations with applicable trailering equipment
• Traction Select System: Includes a tow/haul mode

Four-wheel drive can help manage traction, while low-range gearing supports appropriate slow-speed conditions.

Towing, Payload, and Capability

Maximum trailer ratings for the Yukon XL vary by engine, drivetrain, and equipment:

• 5.3-liter V8: 7,800 pounds with 2WD or 7,500 with 4WD; 8,200 and 8,000 pounds, respectively, with the Max Trailering Package
• 6.2-liter V8: 7,500 pounds with 2WD or 7,300 with 4WD; 8,000 and 7,800 pounds, respectively, with the Max Trailering Package
• Duramax diesel: 7,900 pounds with 2WD or 7,700 with 4WD, including when equipped with the Max Trailering Package

The ratings assume a standard-equipped vehicle, driver, and required trailering equipment. Passengers, cargo, and optional equipment reduce the maximum trailer weight. Before planning a camper or boat trip, check the specific vehicle’s labels, hitch requirements, and owner’s manual, including payload and tongue-weight limits.

Driving Experience and Efficiency

• Premium Smooth Ride suspension: Standard on Elevation
• Magnetic Ride Control: Standard on AT4, AT4 Ultimate, Denali, and Denali Ultimate
• Air Ride Adaptive Suspension: Standard on Ultimate trims and available on qualifying AT4 and Denali configurations
• Fuel capacity: Approximately 28 gallons

Suspension choices help tailor the SUV to long drives and changing loads.
