Full-size SUVs can help solve space problems, and the 2026 GMC Yukon gives Stillwater, OK, families two ways to do it. The Yukon measures 210.1 inches long and offers up to 122.8 cu. ft. of cargo capacity. Yukon XL stretches further to be approximately 225 inches and increases maximum cargo room to 144.5 cu. ft. Both can seat up to 8 passengers depending on configuration. But the important difference isn't maximum capacity with the seats folded. It's what happens when the family fills all 3 rows and still expects the luggage to come along. Behind its third row, Yukon provides 25.5 cu. ft. of cargo space. Yukon XL has 41.5 cu. ft. That's an impressive amount of additional cubic feet before folding a single passenger seat, which is precisely where the longer body earns its keep. Fold the third row and capacity increases from 72.5 to 93.6 cu. ft.; fold the second as well and the comparison becomes 122.8 versus 144.5 cu. ft. Bigger outside, yes, but importantly, bigger in places families can use. The 5.3L V8 produces 355 hp and 383 lbs. ft. of torque and provides the traditional V8 starting point. The available 6.2L V8 raises output to 420 hp and 460 lbs. ft. of torque, making it the horsepower leader. Then there's the 3.0L Duramax® Turbo-Diesel with 305 hp and 495 lbs. ft. of torque. All pair with a 10-speed automatic transmission. Families comparing Yukon powertrains should think about towing and vehicle use before simply choosing the largest horsepower number. Yukon Elevation includes heated front and second-row outboard seating. Higher trims can add heated and ventilated front seats, upgraded leather appointments, and additional power-adjustable equipment. Available Magnetic Ride Control and Air Ride Adaptive Suspension add another layer to the experience by changing how this large SUV responds to varying road conditions. On something this substantial, suspension technology can be more meaningful than another decorative cabin feature. A large diagonal infotainment display dominates the dashboard for your infotainment needs. A 15-inch Head-Up Display and rear-seat media system are also available. Available Super Cruise® adds hands-free driver assistance on compatible roads. Properly configured Yukon models can tow up to 8,400 lbs., giving owners room for substantial recreational trailers. A maximum tow rating tells you what a properly configured SUV can handle; trailering technology helps with the business of hitching, maneuvering, and driving with that load attached.
