Designed for drivers who demand serious performance without compromising comfort or style, this AT4 delivers the full package. 

At its heart is the revered 6.2-liter EcoTec3 V8 engine—an absolute powerhouse that puts down 420 horsepower and 460 lb-ft of torque. It’s the biggest and boldest gas engine GMC offers, and it transforms this Sierra into a confident, high-performing machine whether you’re pulling a trailer, passing at highway speeds, or crawling over rough terrain.

Off-road, the Sierra AT4 proves its trail-rated credentials with a factory 2-inch suspension lift, off-road tuned Rancho shocks, a dual-speed transfer case, hill descent control, and protective skid plates. It’s not just capable—it’s confident, offering superior approach and departure angles and the kind of rugged durability you can trust. It also boasts a towing capacity of up to 8,900 lbs and a payload rating around 2,000 lbs, making it a highly versatile hauler ready for work or play. Whether you’re towing your boat to the lake or loading up the bed with gear, the AT4 is equipped for anything. 

Visually, the grey exterior brings a sophisticated edge to the AT4’s aggressive design. Black chrome accents, body-color bumpers, signature red tow hooks, and LED lighting create a bold, distinctive presence on the road. 18-inch machined aluminum wheels wrapped in all-terrain tires give it a planted stance and trail-ready grip, while the signature AT4 badging reminds everyone this is no ordinary Sierra. 

Inside, this truck effortlessly blends ruggedness with refinement. The Jet Black interior with Kalahari contrast stitching sets a premium tone, while leather-appointed seating, real aluminum trim, and AT4-specific accents give the cabin a sporty, upscale feel. Heated and ventilated front seats, a heated steering wheel, dual-zone automatic climate control, a power sliding rear window, and remote start offer exceptional comfort and convenience. The Crew Cab configuration ensures spacious rear-seat legroom and clever storage options throughout. 

Technology is a highlight in this 2022 AT4.

Paired with a crisp 12.3-inch fully digital driver display and premium sound system, this truck delivers a connected and immersive driving experience. USB-C ports and wireless phone charging further enhance functionality and ease of use. 

Safety is just as advanced, with features like forward collision alert, lane keep assist, automatic emergency braking, front pedestrian braking, and a high-definition rearview camera all coming standard.
