2022 GMC Sierra 3500HD

Answer the call to adventure in Sierra HD AT4. Sierra HD AT4s unique adventure-ready styling and capability are made to take on off-road obstacles. Sierra HD AT4s durable yet refined cabin offers premium materials and advanced technologies for comfort and control. The Jet Black interior with Kalahari accents features a leather-wrapped heated steering wheel, 10-way power front seats with heated and ventilated leather seating surfaces and heated rear outboard seats. Sierra HD AT4 conquers rugged challenges with powerful engine options and advanced off-road capabilities. Go off-road with a max ground clearance of more than 10 inches, along with a max front-approach angle of nearly 27 degrees on select models. Take on the trail with Rancho shocks, skid plates, an Eaton automatic locking rear differential and all-terrain tires. Billy Rehbock, with MOTORTREND, wrote...Choosing a pickup trim can be a bewildering process, but we think the Sierra 2500HD AT4 provides the right balance of capability and features. We would also equip it with 4WD, the torquey 6.6-liter turbodiesel, and the 10-speed automatic transmission for the best driving experience. In addition to off-road suspension and skid plates, the AT4 also boasts trailering assistance tech and a distinctive appearance thanks to trim-specific cosmetic touches. The clever GMC MultiPro tailgate is standard, and inside, there is an 8.0-inch touchscreen, a 15-inch head-up display, and heated and ventilated seats. It comes with driver assistance features, too, including lane departure warning, rear cross-traffic assist, and parking sensors. It also has 15 camera angles including a 360-degree camera system for parking. JD Powers said...The GMC Sierra AT4 looks good, offers plenty of utility, and makes owning a diesel-powered pickup mighty affordable. The ride and handling are better than the Sierras standard suspension, and the optional mud-terrain tires make the truck feel unstoppable in the slop.
