Based on GM's excellent full-size truck platform, GMC Yukon XL and Chevrolet Suburban have much in common, but there are some key differences that go well beyond styling.

At the top of the GMC model line is the Yukon XL Denali, an upscale version of the Yukon XL that comes with a powerful 6.0-liter V8 and all-wheel drive.
