For the last model year of the GMT900-based Yukon, GMC is giving its full-size line of SUVs a few insignificant changes, just as Chevy is doing with the Tahoe and Suburban. By far and large, the updates are related to the color palette, with the deletion of the Steel Gray Metallic and Gold Mist Metallic hues and the addition of Champagne Silver Metallic, Dark Blue Metallic, and Deep Indigo Metallic.
