Built for Rough Ground
What Makes a GMC AT4 Different?
Generally speaking, AT4 models are meant to handle challenging and uneven terrain like muddy trails or gravel roads. So you'll see vehicles with things like skid plates, off-road tuning, and hill descent control (like on the GMC Sierra AT4).
Externally, you'll see model-specific wheels and badging, unique grille designs, and lots of dark and moody features for a more rugged and aggressive visual finish. However, just because we're in rugged territory, it doesn't mean the comfort is compromised — far from it! Inside the cabin, you can expect to see and experience heated seats, leather materials, premium audio, and advanced infotainment.
There are cutting-edge technology stacks in the mix too, with features like automatic emergency braking, forward collision alert, parking assistance, lane assistance, and plenty more.
