A 3.0-liter turbodiesel inline-6 rounds out the lineup for those prioritizing efficiency on long hauls. For those drawn to the AT4 trim, a two-speed transfer case and off-road-tuned suspension system elevate the Yukon XL's trail-ready credentials, giving it serious capability when the pavement ends. Maximum towing capacity reaches up to 8,200 pounds when properly equipped.
