Engine and performance

A giant SUV deserves an equally massive engine to power it—and the GMC Yukon XL has three different powertrain options to choose from. The table outlines each in detail.

Cargo and towing

On top of being able to haul around seven of your best friends, the Yukon XL’s massive size allows it to carry plenty—and tow even more behind. Here’s a quick breakdown of the cargo capacity specs for the Yukon XL:  
  • Cargo volume behind first row: 145 cubic feet 
  • Cargo volume behind second row: 93.8 cubic feet
  • Cargo volume behind third row: 41.5 cubic feet 
Compared to similar-sized SUVs from other auto brands, 41.5 cubes with all the seats in use is an incredible cargo capacity. That means that you can store plenty of luggage and other travel supplies in the trunk of your Yukon XL, even before you hook up a trailer to tow whatever else you need. 
As mentioned, when equipped with its 6.2-liter V8 engine and GMC’s Max Trailering Package, the 2022 Yukon XL can tow up to 8,400 pounds without any problems. Even without the trailer package, the SUV can tow up to 8,100 pounds
That’s more than enough towing capacity for most drivers. To be sure, it is on par with similar giant SUVs like the Lincoln Navigator, which can haul up to 8,700 pounds
