The standard Yukon XL benefits from a similarly updated 355-hp, 5.3-liter V-8, which makes it about as quick as the last-generation Denali. EPA fuel-economy estimates are up 1 mpg in the city in all power-trains, and highway ratings improve by up to 3 mpg. The towing capacity remains healthy, ranging from 7900 to 8300 pounds.
