Its 5.3L V8 gas engine pairs with a 10-speed automatic transmission, giving drivers smooth power delivery for daily errands, highway merging, and loaded family travel. Inside, the cabin is thoughtfully equipped with heated front seats, a heated steering wheel, second-row outboard heated and power-release seats, and power-folding third-row seats, so switching between passengers and cargo is simple. The long-wheelbase Yukon XL body makes the most of that flexibility by expanding space behind the third row, a major benefit when sports gear, luggage, groceries, and work supplies all need to come along. Technology feels modern from the first drive thanks to the 16.8" diagonal Premium GMC Infotainment System, 11" diagonal Driver Information Center, Wireless Smartphone Charging, and Bose 10-speaker sound system.
