If you're someone who craves off-road capability without sacrificing luxury and tech, then buckle up, because this truck might just be your soulmate on wheels. We got our hands on this rugged beauty for a proper test drive, and let me tell you, it did not disappoint. From its intimidating stance to its surprisingly refined interior, the AT4 is designed to conquer trails and cruise in comfort. So, let's cut to the chase and see what makes this GMC Sierra variant stand out from the crowd.

First Impressions: Looks That Mean Business

When the 2022 GMC Sierra AT4 rolls up, you know it means business. This truck doesn't whisper its intentions; it roars them. The AT4 trim level brings an aggressive, off-road-ready aesthetic that's both functional and undeniably cool. The signature C-shaped LED lighting up front gives it a distinctive, commanding presence, while the dark chrome grille and aggressive front bumper with its red recovery hooks scream adventure. Seriously, those red hooks aren't just for show; they're a statement that this truck is ready to pull you out of (or into!) some serious situations. The beefy all-terrain tires wrapped around unique 18-inch wheels are another dead giveaway that this Sierra is built for more than just mall crawling. Even the badging is subtle yet assertive, letting everyone know you're piloting an AT4. And let's not forget the AT4-specific interior accents, like the premium embossed seats, which add a touch of rugged sophistication. It’s a truck that looks as capable as it is, and that’s a huge part of its appeal. When you step back and take it all in, you get the sense that this vehicle is engineered for toughness, built to withstand the elements, and ready to tackle whatever you throw at it. The proportions are just right – imposing without being obnoxious, and it carries itself with a confident swagger that’s hard to ignore. The wheel arches are pronounced, adding to its muscular profile, and the overall design language emphasizes its go-anywhere attitude. It’s a truck that demands attention, not because it’s flashy, but because it’s inherently rugged and purposeful in its design. The way the light hits the sculpted body panels, the subtle aerodynamic enhancements, and the thoughtful integration of functional elements like the skid plates beneath – it all adds up to a vehicle that’s as visually compelling as it is capable.

Under the Hood: Powering Your Adventures

Now, let's talk about what's under that long hood. For the 2022 GMC Sierra AT4, you have a couple of potent engine options, but the one we're most excited about is the legendary 6.2L V8. This bad boy pumps out a massive 420 horsepower and 460 lb-ft of torque, paired with a smooth 10-speed automatic transmission. Mated with the AT4's standard four-wheel-drive system, this powertrain is an absolute beast. Whether you're merging onto the highway, towing a heavy load, or climbing a steep, muddy incline, this engine delivers effortless power. The sound alone is intoxicating – a deep, throaty rumble that lets you know there's serious muscle at your disposal. But it's not just about raw power; it's about how that power is delivered. The 10-speed auto is incredibly responsive, keeping the engine in its sweet spot for optimal acceleration and fuel efficiency. You barely notice the shifts, which is impressive given the torque it's managing. For those who might not need quite that much V8 grunt, there's also the 3.0L Duramax turbodiesel engine, offering fantastic fuel economy and ample torque for towing and off-roading, though it lacks the same visceral thrill as the V8. Regardless of your choice, the AT4 is engineered to handle it all. The suspension is tuned for off-road prowess, featuring a 2-inch factory lift and Rancho shocks that soak up bumps and ruts like they're nothing. This translates to a surprisingly compliant ride on pavement too, making it a comfortable daily driver. The enhanced traction control system, hill descent control, and locking rear differential are standard, ensuring you have the tools you need to navigate challenging terrain with confidence. It’s this combination of robust engine options and off-road-focused hardware that truly defines the AT4's capability.

Interior Comfort and Tech: A Surprisingly Plush Cabin

Step inside the 2022 GMC Sierra AT4, and you might just forget you're in a hardcore off-road machine. GMC has done a stellar job of blending rugged capability with premium comfort and cutting-edge technology. The AT4-specific interior treatments, like the bold Jet Black or Graystone interior with Sienna Brown accents and unique stitching, give it a distinct personality. The seats are plush and supportive, offering plenty of adjustability for even the longest drives. We were particularly impressed with the quality of the materials used throughout the cabin – soft-touch plastics, genuine aluminum trim, and the aforementioned premium leather. It feels decidedly upscale, a far cry from the utilitarian interiors of some older trucks. But it's not just about luxury; it's about smart design and technology. The centerpiece is the large, intuitive touchscreen infotainment system. It supports Apple CarPlay and Android Auto, allowing seamless integration of your smartphone for navigation, music, and calls. The system is responsive and easy to navigate, even while you're bouncing around off-road. GMC also packs in plenty of USB ports and available wireless charging to keep all your devices powered up. For added convenience, you'll find features like a heated steering wheel, heated and ventilated front seats, and dual-zone automatic climate control. The cabin is also impressively quiet, thanks to excellent sound deadening, making conversations easy even at highway speeds. Storage is plentiful, with a spacious center console, door pockets, and even under-seat storage options. It’s clear that GMC didn't just slap some off-road bits onto a regular Sierra; they created a truly premium experience that happens to be incredibly capable. The attention to detail in the cabin is remarkable, from the placement of the controls to the ambient lighting that adds a sophisticated touch in the evening. It’s a space that feels both commanding and comfortable, ready for a weekend adventure or a daily commute.

Off-Road Prowess: Taming the Wild

This is where the 2022 GMC Sierra AT4 truly shines. It’s not just about looking the part; it’s about being the part. The 2-inch factory lift, standard four-wheel drive with a 2-speed transfer case, and locking rear differential give you the mechanical advantage needed to tackle challenging terrain. The skid plates protecting the underbody are a must-have for any serious off-roader, shielding vital components from rocks and debris. During our test drive, we took the AT4 on a moderately challenging off-road course, and it handled everything with surprising ease. The Rancho shocks provided a smooth ride over rough patches, absorbing impacts that would have sent shivers through a lesser vehicle. The all-terrain tires offered excellent grip, even on loose gravel and mud. The hill descent control worked flawlessly, allowing us to navigate steep downhill sections with confidence, just using the brake pedal lightly. The traction control system was quick to react, managing wheel slip effectively and keeping us moving forward. The multi-color 15-inch diagonal Head-Up Display (HUD) is a game-changer for off-roading, allowing you to keep your eyes on the trail while still seeing critical information like speed, navigation prompts, and even off-road inclinometer data. GMC's ProGrade™ Trailering System is also available, but even without it, the AT4’s off-road manners are impeccable. It inspires confidence, allowing you to push your boundaries and explore further. Whether you're navigating rocky trails, muddy tracks, or simply dealing with inclement weather, the AT4 is equipped to handle it. The combination of lifted suspension, robust drivetrain, and intelligent electronic aids makes it a formidable off-road companion. It’s the kind of truck that makes you want to find the path less traveled, knowing you have the capability to get there and back.

On-Road Manners and Towing: Versatility Defined

While the 2022 GMC Sierra AT4 is undeniably built for adventure, it doesn't forget its roots as a capable truck for everyday life and work. On the road, it offers a surprisingly refined and comfortable ride, especially considering its off-road suspension setup. The cabin is quiet, the steering is precise, and the powerful V8 engine makes for effortless acceleration and confident passing maneuvers. You can easily live with this truck as a daily driver. The braking is strong and predictable, giving you confidence in stopping power. When it comes to towing, the Sierra AT4 is a true workhorse. With the right configuration, it can tow well over 10,000 pounds, making it suitable for everything from boat trailers to larger campers. The available ProGrade™ Trailering System, with features like hitch guidance and trailer sway control, makes hooking up and managing a trailer significantly easier. The 10-speed automatic transmission is particularly beneficial when towing, as it keeps the engine in its power band more effectively than a traditional 6-speed, reducing strain and improving efficiency. The Sierra's strong frame and robust suspension contribute to a stable and secure towing experience. We didn't get to tow a massive load during our test, but the confidence the AT4 inspires, combined with its potent powertrain, suggests it would handle towing duties with aplomb. It’s this blend of off-road tenacity and on-road civility, coupled with its towing prowess, that makes the AT4 such a versatile package. It’s not just a weekend toy; it’s a fully capable tool for work and play, ready for any challenge.
