The Denali trades the standard Yukon XL's black grille for a bright mask of fine-metal mesh, but swaps the chrome bumpers for body-color bumpers to keep the overall flash level about equal. Round fog lights are neatly tunneled into the lower part of the front bumper. (All Yukon XLs have fog lights, but they are less conspicuous on standard models.) Oddly shaped lower body cladding incorporates front and rear stone guards and blends nicely into the Denali's color-keyed running boards.
