2026 GMC YUKON XL DENALI ULTIMATE 4WD 3.0L DURAMAX DIESEL SUPER CRUISE AIR RIDE MAX TRAILERING 24s VOLCANIC RED LANCASTER PA
This 2026 GMC Yukon XL Denali Ultimate 4WD is powered by the 3.0L Duramax turbo-diesel inline-six paired with a 10-speed automatic transmission. Finished in stunning Volcanic Red Tintcoat, this is GMC's flagship extended-length SUV loaded with Super Cruise, Air Ride, Magnetic Ride Control, Max Trailering, massage seats, panoramic roof, rear entertainment, and 24-inch wheels.
The 3.0L Duramax produces 305 horsepower and 495 lb-ft of torque, making it an excellent match for the Yukon XL. The diesel's strong low-end torque is ideal for highway cruising and towing, while its efficiency and long-range capability make a lot of sense in a large three-row SUV.
The Denali Ultimate is the top of the Yukon lineup, and the interior reflects it. You get heated and ventilated front seats with power massage, second-row bucket seats, Bose 18-speaker Surround with Centerpoint, an 8-inch rear climate touchscreen, Head-Up Display, Rear Camera Mirror, Connected Navigation, and a Rear Seat Media System. The Dual-Pane Panoramic Power Sunroof opens up the cabin even further.
Ride quality is a major strength. Air Ride Adaptive Suspension and Magnetic Ride Control work together to keep this large SUV composed and comfortable, while the Premium Capability Package with Active Response 4WD and electronic limited-slip differential adds serious traction capability.
Super Cruise brings hands-free driver assistance to compatible roads, while Driver Attention Assist and the Advanced Technology Package add another layer of driver-focused technology.
This Yukon XL is also properly equipped to tow. The Max Trailering Package adds extra-capacity cooling and works with the integrated trailer brake controller, Hitch View, Smart Trailer Integration, and Blind Zone Steering Assist with Trailering.
Outside, the combination of Volcanic Red Tintcoat, massive 24-inch machined and painted wheels, power-retractable assist steps, Vader bodyside moldings, and dual exhaust gives this Ultimate a commanding look.
And because it's the Yukon XL, you get substantially more cargo room behind the third row than the standard-length Yukonan important advantage for family trips when every seat is occupied.
If you're looking for the top Yukon configuration without the fuel appetite of the 6.2L V8, this is a phenomenal setup: Denali Ultimate, 3.0 Duramax, Super Cruise, Air Ride, massage seats, Max Trailering, panoramic roof, rear entertainment, and 24s.
