It's been a while since the GMC Sierra last toured through the styling studios. It was completely redesigned in 2007, at the same time GM restyled its fraternal twin, the Chevrolet Silverado, and little has changed since. That's fine--the Sierra has a conservative but tasteful look that still seems fresh today. The major difference with the Silverado is the GMC's large rectangular grille, which we prefer to the Chevy's somewhat softer front end and corners. We imagine lots of unfortunate car bumpers are stamped with those huge "GMC" letters after accidents, but there's no mistaking the truck for any other brand's pickup. Behind the front end, the Sierra is quite plain, even more stark than the latest Ford F-150; the Toyota Tundra and Nissan Titan try the hardest to evade the usual truck styling cliches and they fail to convince us of their good looks, so playing it safe works out well for GMC.
The Sierra's interior differs from base models to upscale versions. The less expensive versions sport a simple, upright design with larger controls and door handles, the kind that make it better suited for work duty. Pricey versions get a cabin that might fit in a traditionally styled luxury sedan. The upgraded instrument panel has a smoother, lower design, as well as surfaces and materials that come together nicely. The woodgrain trim strikes us as decent but not totally convincing, but otherwise the Sierra is tailored well for the chores it has on its to-do list.
