Brutalism is an art form that came and went quickly, but left a deep crater in cityscapes. Look around at the concrete wonders of the 1970s and you'll see the same regular, angular forms repeated in the GMC Terrain, the most brutalist SUV ever save for one.
That one? The GM HUMMER, the direct styling ancestor of the Terrain. The GMC's just barely out-boxed by that now-dead ute, and it's just a D-cell battery short of the full Transformer look that had a grip on GM design for much of the past five years, on vehicles as oddly linked by it as the Spark, the Sonic, and this crossover.
While the Terrain's exterior is a little more distinctive and macho than the Chevrolet Equinox, along with most other compact crossovers, its instrument panel is much like that of the Chevy: a somewhat V-shaped center stack, housing audio and climate controls, and flanked by large vertically oriented vents, is the center point of the design, and otherwise details and trim look chunky, with the same cloudy metallic surfaces that are now used inside other GMC vehicles.
The new Denali edition mutes the look very indirectly. The grille is mesh; the metallic trim is satin in texture. The cabin wears a soft pad on the dash, stitched with red thread, and the steering wheel has a section of dark woodgrain implanted across a top arc. Denali badges and a unique color palette are the only other details that separate it from the rank and file.
