2027 GMC Yukon XL Specs and Features

Specs and Features Review: 2027 GMC Yukon XL

The 2027 GMC Yukon XL is an extended full-size SUV for shoppers who want three-row passenger flexibility, generous cargo utility, confident capability, and premium GMC character in one vehicle. At Charlie Clark GMC, it gives Stanton, TX, drivers a spacious choice for daily transportation, group travel, long-distance driving, and gear-heavy plans.

Five trims let shoppers choose the personality that best matches their priorities:

• Elevation: The well-equipped foundation of the lineup, focused on comfort, convenience, and everyday versatility
• AT4: The rugged choice for drivers who want a more adventurous design and off-road-oriented capability
• Denali: The luxury-focused trim for shoppers who prioritize premium appointments and advanced convenience
• AT4 Ultimate: A combination of AT4 character and upscale comfort
• Denali Ultimate: The most refined and premium expression of the Yukon XL

Explore the 2027 GMC Yukon XL at Charlie Clark GMC in Stanton, TX, to compare trims and find the configuration that fits the way you travel.

A Cabin That Keeps the Third Row Useful

The Yukon XL’s interior is at its best when every row is needed. With the third-row seat upright, it still provides up to 41.5 cubic feet of cargo volume—enough room to make group travel more practical without immediately folding a seat.

Cargo room expands in three useful stages:

• All three rows in use: Up to 41.5 cubic feet behind the third row
• Third row folded: Up to 93.6 cubic feet behind the second row
• Rear rows folded: Up to 144.5 cubic feet behind the first row

That progression gives owners flexibility for airport pickups, team equipment, vacation luggage, camping supplies, or larger purchases. The approximately 28-gallon fuel tank also suits the Yukon XL’s long-distance focus.

Passenger accommodations are similarly flexible:

• Capacity: Up to eight occupants, depending on configuration
• Second row: A bench maximizes seating, while available captain’s chairs create easier third-row access
• Third row: A standard power-folding split bench changes the passenger-to-cargo balance at the push of a control
• Front space: Up to 44.5 inches of legroom

Choose the Cabin Experience

The trim lineup offers three distinct cabin directions:

• Elevation: Start with leather-appointed seating, heated front seats, a heated steering wheel, heated second-row outboard seats, memory settings, and power-release second-row seats. Available features include a panoramic sunroof and power-sliding center console.
• AT4 and AT4 Ultimate: Create a more adventurous atmosphere. AT4 uses a Forest Storm interior with Mahogany accents and heated and ventilated front perforated leather seating surfaces. AT4 Ultimate changes the look to Obsidian Rush with red accents, full-grain leather, and 16-way power front seats with massage.
• Denali and Denali Ultimate: Emphasize upscale travel. Denali adds an exclusive interior treatment, heated and ventilated front perforated leather seating, and a power-sliding center console. Denali Ultimate uses Woodland Mahogany and full-grain leather and offers executive second-row captain’s chairs with heating, ventilation, massage, and Bose head-restraint speakers.

Executive second-row seating changes total passenger capacity, so shoppers should decide whether maximum occupancy or individual second-row comfort matters more.

An Extended Exterior with Distinct GMC Character

At approximately 225.2 inches long and 76.5 inches tall, the 2027 GMC Yukon XL has the dimensions of a true full-size SUV. GMC balances that scale with features designed to make everyday access more convenient:

• AutoSense Power Liftgate: Available hands-free access to the cargo area when the key fob approaches
• Assist steps: Fixed steps on Elevation and power-retractable steps on select upper trims
• Animated LED lighting: Adds a modern welcome and departure signature
• Large wheel choices: Designs ranging from 20 to 24 inches, depending on trim

The exterior also makes the Yukon XL’s three trim personalities easy to recognize. Elevation has a clean, confident presentation with 20-inch Satin Graphite wheels. AT4 and AT4 Ultimate adopt a high-clearance front fascia, all-terrain tires, recovery hooks, and darker trim-specific finishes. Denali models use signature grilles and brighter detailing, while Denali Ultimate adds a Vader Chrome grille and 24-inch wheels.

Hardware for Mixed-Surface Travel

AT4 models use functional equipment, not only visual accents, to support travel away from pavement:

• High-approach-angle front fascia
• Front skid plate
• Red recovery hooks
• 20-inch wheels with all-terrain tires
• Magnetic Ride Control

AT4 Ultimate adds Air Ride Adaptive Suspension and Active Response 4WD. Even with this equipment, drivers should consider the Yukon XL’s wheelbase, length, weight, and available clearance before selecting a trail.

2027 Yukon XL Exterior Colors

Verified colors shown across the 2027 retail trim lineup include:

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

Availability, restrictions, and pricing depend on trim and configuration.

Three Ways to Power a Full-Size SUV

The 2027 Yukon XL offers three engines, each paired with a 10-speed automatic transmission:

• 5.3-liter V8: It produces 355 horsepower and 383 lb-ft of torque. Standard on Elevation and AT4, it provides familiar gasoline V8 response for everyday full-size SUV driving.
• 6.2-liter V8: It produces 420 horsepower and 460 lb-ft of torque. Standard on Denali, AT4 Ultimate, and Denali Ultimate, and available on AT4, it delivers the lineup’s strongest gasoline output.
• Duramax® 3.0-liter Turbo-Diesel: It produces 305 horsepower and 495 lb-ft of torque and is available across the retail trim lineup. Its low-end torque can support acceleration with a load and steady progress on long grades.

Ride and Traction Equipment

Drivetrain and suspension choices change the Yukon XL’s character as much as its engine does:

• Rear-wheel drive: Available on select trims for shoppers who do not require four-wheel drive
• Four-wheel drive: Offered across much of the lineup and standard on AT4 models
• Magnetic Ride Control: Standard on AT4 and Denali to continually adapt damping to the road
• Air Ride Adaptive Suspension: Standard on AT4 Ultimate and Denali Ultimate to adjust ride height and comfort
• Active Response 4WD: Available or standard on select upper configurations to coordinate traction systems

These systems help the extended SUV remain composed on the highway while supporting traction and ride-height needs in changing conditions.

Trailering Support

GMC lists maximum trailering for the Yukon family at up to 8,400 pounds when properly equipped. A particular Yukon XL’s rating depends on its engine, drivetrain, axle ratio, trim, and equipment, so the vehicle-specific trailering label and owner information should guide every towing decision.

Available trailering tools can make setup and low-speed maneuvering easier:

• Hitch View
• Integrated trailer brake controller
• Blind Zone Steering Assist with Trailering
• Extra-capacity cooling system

Technology Built Around Visibility and Travel

The Yukon XL’s technology is not limited to entertainment. Its displays, cameras, connected features, and driver aids are especially useful in a vehicle with an extended footprint.

A 16.8-inch Premium GMC Infotainment System with Google built-in compatibility serves as the main interface. An 11-inch Driver Information Center places driving data directly ahead, while available equipment such as a 15-inch Head-Up Display can project key information closer to the driver’s line of sight.

Technology for Different Parts of the Journey

• At the wheel: Available Super Cruise can assist with steering, acceleration, and braking on compatible roads while the driver remains attentive.
• In parking areas: HD Surround Vision and multiple selectable camera views help reveal objects and vehicles around the SUV.
• While towing: Camera views and Hitch View can support alignment and monitoring during setup.
• For rear passengers: The available Rear-Seat Media System uses dual 12.6-inch HD touchscreens, Bluetooth® headphone compatibility, and two HDMI ports.
• For connected ownership: OnStar® features support compatible remote commands, Automatic Crash Response, and select in-vehicle services.

Five Additional Technology Highlights

• Surround Vision Recorder: Saves video from exterior cameras to a compatible USB drive while the vehicle is operating.
• Security Recording: Can begin recording after the vehicle alarm has been triggered for 30 seconds.
• Wireless smartphone charging: Reduces cable clutter in the front console area.
• Bose audio: Offered as a 10-speaker system or an 18-speaker system on select upper trims.
• Rear Camera Mirror: Available to provide a camera-based view behind the vehicle when cargo or passengers obstruct the conventional mirror view.

Driver Assistance for Busy Roads and Tight Spaces

More than 17 safety and driver-assistance features are offered on the 2027 GMC Yukon XL. The most useful systems address the situations that can be challenging in a full-size SUV: monitoring blind zones, watching cross traffic, judging surrounding space, and responding to hazards ahead.

Five notable features include:

• Enhanced Automatic Emergency Braking: Can increase or provide hard braking when it detects a potential collision with a vehicle ahead.
• Blind Zone Steering Assist: Can alert the driver and provide a brief steering input when another vehicle is detected in the lane the Yukon XL is entering.
• Intersection Automatic Emergency Braking: Can provide warnings and braking support when it detects cross traffic during a potential intersection collision.
• Front Pedestrian and Bicyclist Braking: Can warn the driver and provide emergency braking in certain conditions when a pedestrian or bicyclist is detected ahead.
• Rear Cross Traffic Braking: Can warn the driver and apply hard braking when a crossing vehicle is detected while reversing.

Available Enhanced Automatic Parking Assist can steer, brake, and shift while helping the driver enter or leave a detected parking space. Super Cruise can assist on compatible roads, but neither system replaces an attentive driver who is prepared to intervene.
