The Sierra's exterior styling changed with its 2007 redesign. It's different and modernized, and though it has different hood and fender shapes, it still isn't wildly different from the Silverado. Its headlights are stacked vertically, like the Silverado's, but the Sierra's are more squat. A taller bumper rests immediately under them. Where the Silverado's disproportionately large grille is chrome-heavy, it's dark and only rimmed with chrome in most of the Sierra trims.
