The 2025 GMC Sierra HD AT4/AT4X: What We Like
Both trims are designed to dominate the toughest terrain. From factory lifts to all-terrain tires to skid plates that protect the undercarriage, these trucks are your ultimate partner for rock crawling in Moab or hauling a camper through the mountains. Meanwhile, either engine has the muscle to tow what you need – whether that’s the standard, 401-hp 6.6L V8 gas engine or the available, 470-hp 6.6L Duramax® turbo diesel.
Who says you can’t be comfortable while you’re “roughing it”? Both interiors offer rugged luxury with the AT4 Jet Black leather seats and Kalahari accents or the AT4X’s Obsidian Rush leather seats and authentic Vanta Ash Wood accents. You’ll also get customizable comfort with power-adjustable, heated, and ventilated front seats, as well as dual-zone automatic climate control with rear AC vents.
