The 2026 GMC Terrain lineup expands with two standout new trims: the rugged AT4 and the sophisticated Denali.

The AT4 is built for adventure, featuring all-terrain tires, underbody skid plates, bold red recovery hooks, and a raised ride height for improved off-road capability. The Denali takes the opposite approach, exuding refinement with heated rear seats, exclusive 19-inch wheels, and a finely tuned suspension engineered for comfort and poise.

Both trims sit atop the Terrain's turbocharged 1.5L engine (175 hp, 275 lb-ft torque) and standard tech like Google built-in infotainment, wireless Apple CarPlay and Android Auto, and adaptive cruise control. Whether you're seeking adventure or luxury, the 2026 Terrain has a trim for you. Call Markquart Motors at (715) 833-0444 to find your perfect match, or browse current inventory online.
