STORY

The GMC Yukon XL is the extended-length version of the full-size Yukon SUV, introduced for 2000 as the successor to the GMC Suburban. Its longer wheelbase provides greater third-row space and cargo capacity while retaining V8 power and heavy towing capability. Like the standard Yukon, it is offered in premium Denali trim and shares its platform with the Chevrolet Suburban.
