Alright guys, let's dive deep into the 2022 GMC Sierra 1500 AT4X review! If you're in the market for a full-size pickup truck that doesn't just look tough but is tough, especially when the pavement ends, then you've probably heard whispers – or maybe even shouts – about this beast. GMC really went all out with the AT4X trim, essentially taking their already capable AT4 and cranking the off-road knob up to eleven. We're talking about a truck designed to conquer crawling over rocks, navigating muddy trails, and generally making a mockery of terrains that would send lesser vehicles packing. This isn't just about slapping on some bigger tires and a sticker; this is a thoroughly engineered machine built for adventure.

What Makes the AT4X So Special?

So, what sets the 2022 GMC Sierra 1500 AT4X apart from the standard Sierra or even the regular AT4? Well, for starters, it's the standard equipment that comes with it. GMC knew they wanted to create a halo off-road model, and they didn't hold back. The most significant upgrades are found underneath. We're talking about standard Multimatic DSSV spool-valve dampers, which are pretty trick pieces of suspension tech usually found in high-performance race cars and serious off-road vehicles. These dampers are designed to offer exceptional control and damping across a wide range of speeds and terrains, meaning you get a smoother ride on the highway and better control when you're bouncing around off-road. Seriously, these aren't your average shocks, guys.

Beyond the fancy dampers, you also get front and rear electronic locking differentials. This is huge for off-roading. A locking differential ensures that both wheels on an axle spin at the same speed, even if one loses traction. This means you can keep moving forward even if one tire is completely off the ground or stuck in mud. Coupled with a 2-speed transfer case with a dedicated low-range gear, the AT4X gives you serious crawl capability. The ride height is also lifted by about an inch compared to other Sierra models, giving you better ground clearance for tackling obstacles. And let's not forget the standard skid plates protecting the vital underbody components. GMC didn't just add a few badges; they genuinely enhanced the truck's capability. The AT4X also boasts larger diameter performance Goodyear Wrangler Territory MT tires, which are serious mud-terrains, wrapped around 18-inch wheels. These tires offer incredible grip off-road, though they do add a bit of road noise, which we'll get to.

Under the Hood and Drivetrain

Now, let's talk power, because even an off-road beast needs a strong heart. The 2022 GMC Sierra 1500 AT4X comes standard with the 6.2-liter V8 engine. This is GMC's powerhouse, putting out a healthy 420 horsepower and 460 lb-ft of torque. Mated to a smooth-shifting 10-speed automatic transmission, this combination provides plenty of grunt for towing, hauling, and, most importantly, powering your way through challenging off-road situations. The V8's low-end torque is especially beneficial when you need to slowly and deliberately climb over rocks or pull yourself out of a sticky situation. It’s a confident and capable pairing that feels right at home in this truck.

For those who crave even more control, the AT4X includes GMC's Terrain Mode. This is a one-pedal driving system designed for off-road use. You can accelerate and decelerate using just the throttle pedal, allowing you to focus more on steering and navigating obstacles. It’s incredibly intuitive and makes crawling over technical terrain feel much more controlled and less stressful. The combination of the powerful V8, the refined 10-speed auto, the advanced suspension, and the selectable locking differentials truly makes the AT4X a formidable off-road machine. You can feel the engineering and thought that went into making this truck as capable as it is. It’s not just a concept; it’s a reality you can drive off the lot.

Interior Comfort and Tech

While the 2022 GMC Sierra 1500 AT4X is built for mud and rocks, GMC understands that most of its life will likely be spent on the road. So, they didn't skimp on the interior. Stepping inside the AT4X feels like entering a luxury lodge, not a utilitarian workhorse. The seats are premium leather, and ours were in a really nice dark finish with attractive stitching. They are both heated and ventilated, which is a godsend on long drives or extreme weather days. The build quality feels top-notch, with soft-touch materials used extensively throughout the cabin.

Infotainment is handled by a 13.4-inch diagonal GMC Infotainment System with Google built-in. This is a large, vibrant touchscreen that's responsive and easy to use. Having Google built-in means you get integrated Google Maps, Google Assistant, and the Google Play Store, which is super convenient for navigation and entertainment on the go. Apple CarPlay and Android Auto are also standard, of course. Beyond the main screen, there's a 12.3-inch diagonal digital driver information center that's highly customizable, and a 15-inch diagonal Head-Up Display (HUD). This HUD is fantastic, projecting key information like speed, navigation prompts, and driver assistance alerts right into your line of sight, allowing you to keep your eyes on the road – or the trail.

Overall, the cabin is a very comfortable and high-tech space. It strikes a great balance between rugged capability and premium comfort. You get all the creature comforts you'd expect in a luxury SUV, but within a truck that can handle serious abuse. It's a versatile package that works for daily commuting, family road trips, and hardcore off-roading. The attention to detail in the interior design and technology integration is truly impressive, making the AT4X a pleasure to drive no matter the situation. It’s a testament to GMC’s ability to blend luxury with performance.

Off-Road Performance: Does it Deliver?

This is the million-dollar question, right? Does the 2022 GMC Sierra 1500 AT4X actually live up to its off-road hype? In a word: absolutely. We took this truck on some challenging trails, and it impressed us at every turn. The Multimatic DSSV dampers really shine here. They soak up bumps and impacts with a composure that's frankly astounding for a truck of this size and capability. You can feel the suspension working to keep the tires planted and the body controlled, even over rough, uneven terrain. This translates to a much more comfortable and confidence-inspiring ride off-road compared to many other trucks.

The electronic locking differentials are game-changers. Engaging the rear locker, and then the front locker when needed, allowed us to power through sections that would have easily stopped other vehicles. The truck just claws its way forward with impressive tenacity. The 2-speed transfer case with its low-range gear provides the necessary torque multiplication for crawling over obstacles at a snail's pace, giving you precise control. The added ground clearance from the factory lift is also a huge benefit, reducing the worry about scraping skid plates or undercarriage components on rocks and logs. Speaking of skid plates, the standard aluminum front- and steel rear-skid plates offer decent protection for the drivetrain components.

The Goodyear Wrangler Territory MT tires are aggressive and provide excellent grip in mud, dirt, and on rocks. While they do contribute to some road noise on the highway, their off-road performance is undeniable. The combination of these elements – the robust suspension, the locking diffs, the low-range gearing, the protective underbody armor, and the aggressive tires – creates a package that is genuinely trail-ready right out of the box. You don't need to immediately invest in aftermarket parts to make it capable. It’s designed for adventure, and it performs exceptionally well when you take it off the beaten path. It truly redefines what a factory-built, full-size off-road pickup can do.

On-Road Manners and Fuel Economy

While we've waxed poetic about its off-road prowess, it's important to address how the 2022 GMC Sierra 1500 AT4X handles everyday driving. For such a capable off-road machine, it's surprisingly refined on the road. The Multimatic DSSV dampers, while excellent off-road, also contribute to a much smoother and more controlled ride on pavement than you might expect. It minimizes body roll in corners and smooths out rough patches, making for a comfortable daily driver. The cabin is also well-insulated, quieting down the road noise, although those aggressive MT tires do make their presence known slightly at higher speeds.

The 6.2-liter V8 engine provides effortless acceleration for merging onto highways or passing slower traffic. The 10-speed automatic transmission shifts smoothly and keeps the engine in its power band. It's a powerful and responsive combination that makes driving the AT4X enjoyable. However, let's talk fuel economy. With the big V8, aggressive tires, and the added weight of its off-road components, the AT4X is not a fuel sipper. Expect to see EPA estimated ratings of around 14 mpg city and 18 mpg highway. In real-world driving, especially if you do a fair bit of off-roading or towing, those numbers will likely be even lower. So, if fuel efficiency is your top priority, this might not be the truck for you. But then again, you're probably not looking at the AT4X if MPG is your main concern.

The Verdict: Who is the AT4X For?

So, after all is said and done, who should be buying the 2022 GMC Sierra 1500 AT4X? This truck is squarely aimed at the serious off-road enthusiast who also wants the luxury and capability of a premium full-size pickup. If you plan on taking your truck on challenging trails, rock crawling, or just want the peace of mind that comes with having the most capable factory-built off-road Sierra available, the AT4X is an outstanding choice. It offers a significant step up in off-road capability compared to the standard AT4 or other trims, thanks to its specialized suspension, locking differentials, and protective underbody gear.

It's for the guy who wants to hook up a trailer, drive to a remote campsite or hunting spot, and not worry about whether his truck can handle the access road. It's for the weekend warrior who wants to tackle Rubicon-style trails without immediately needing to bolt on thousands of dollars in aftermarket suspension components. The luxury interior and powerful V8 engine mean that you don't have to sacrifice comfort or performance for capability. It’s a premium package that justifies its premium price tag if your needs align with its strengths. If you're looking for the pinnacle of factory-built off-road luxury in a half-ton truck, the 2022 GMC Sierra 1500 AT4X is definitely worth a serious look. It's a highly competent, comfortable, and undeniably capable machine.
