Vehicle Overview

The Yukon XL is GMC's flagship SUV and a corporate cousin to the Chevrolet Suburban and Cadillac Escalade ESV. It is a larger version of the Yukon, measuring some 20 inches longer. All will be redesigned for 2015 and based on GM's new full-size pickups, the Chevrolet Silverado and GMC Sierra. Competitors include the Ford Expedition EL and Toyota Sequoia.

For the last year of the current design, the heavy-duty Yukon XL 2500 model is available to fleet buyers while the only retail model is the regular-duty 1500 series. It offers seats for up to nine people and is available with a choice of V-8 engines that feature fuel-saving cylinder-deactivation technology that shuts down four cylinders under light loads. SLE and SLT models are available with rear- or four-wheel drive, and the top-shelf Denali comes with rear-wheel drive or permanently engaged all-wheel drive.
New for 2014
Besides eliminating the heavy-duty 2500 model, the only other change of note is that SLE models add the Convenience Package as standard. This includes power-adjustable pedals, remote start, rear parking assist and a backup camera with a display in the rearview mirror.
