2022 GMC Sierra 1500 AT4X First Drive

gmc sierra-1500 Complete overview

We were super happy when GMC finally ran out of the company’s worst kept secret: the new one 2022 GMC Sierra 1500 AT4X. Although we appreciated the all-new Sierra 1500 AT4 when it debuted in 2019, we had a few complaints. The truck’s interior was substandard, its technology a generation old, its exterior design polarizing, and frankly, its included off-road equipment was not what we expected. Over the years, the Sierra 1500 AT4 has grown on us and become one of our favorite mid-range terrain pickups. But we still wanted more. Well, more has finally come, and it’s called the 2022 GMC Sierra 1500 AT4X.

Trick Multimatic DSSV Muffler

The most impressive improvement of the 2022 GMC Sierra 1500 AT4X comes from the introduction of Multimatics DSSV damper. First introduced to the pickup world on the 2016 Chevrolet Colorado ZR2, the Multimatic DSSV dampers replace the standard shock piston and shim stack with flush valves that can be set so that under light pressure (on the road) they are soft and compliant, and under hard pressure (like large bumps in terrain) they can solidify sharply. By using three separate slide valves, the DSSV dampers can provide both position and speed sensitive damping in the same package. We did a deep dive Multimatic DSSV dampers when they debuted in Colorado, and in addition to being expanded for use on the Sierra 1500 AT4X, the same technical concept still applies – read about it here.

Luxurious interior design times

2022 The GMC Sierra 1500 AT4X is an off-road truck, but that does not mean that the company was stingy when it came to the interior. AT4X competes only with the new Denali Ultimate upholstery and is equipped with heated and ventilated 16-way adjustable front seats, upholstered in full-grain leather, with a new massage function (which is fantastic). A new Obsidian Rush interior paint has leather accents and authentic Vanta wood moldings with open pores. Providing the songs is a Bose Premium sound system with 12 speakers with Centerpoint surround sound. A 15-inch head-up display is standard, as is a 12.3-inch digital instrument panel and 13.4-inch infotainment screen. During our time with the truck, we found that the interior was exceptionally quiet, the seats extremely comfortable, and we really enjoyed the amount of information from the huge range of screens. We understand that digital displays can be a distraction for some, but we appreciate them. The design of this new interior is completely in place, and we especially like the genuine wood and leather accents and the massaging front seats. This is the interior like GMC should have had since 2019But better late than never.

Travel and handling on the road

Going out on the road in an off-road truck often involves sacrifices. Thankfully, this is not the case with the 2022 GMC Sierra 1500 AT4X. On the motorway, the truck’s gait is firm without being hard, which is proof of the Multimatic DSSV dampers. Speed ​​bumps and highway waves are easily handled and do not disturb the truck or its passengers. Winding mountain roads are also not a match for the 1/2-ton off-road car, which tracks true and flat, but even a hint of body swing, no matter how narrow the curve is. Fighting against the mentioned curves was made easier by the truck’s well-weighted but still very responsive steering. We also appreciated the truck’s fixed but easily modulated brake pedal, which allowed us to drive deep into the curves and make the truck slow down quickly without disturbing the chassis. The Sierra AT4X really handled more like a performance SUV than a 1/2-tonne pickup on the sidewalk.

We also enjoyed the performance of GMC’s proven 6.2-liter V-8 engine. Pumping out 420 hp and 460 lb-ft of torque, the 6.2-liter V-8 has plenty of power to fold, pass and maybe even a little small tire spin… not that we could ever be accused of such shine. The power from the V-8 engine is conducted through a 10-speed automatic transmission, which can now be operated using steering wheel-mounted vanes. When shifted to “L”, the paddles become active and allow the driver to select the maximum gear for the transmission. We used this function extensively during our time on the mountain roads and found that the gears 3 to 5 were good for keeping the descent under control without overexerting the friction brakes.

Control where it goes – terrain

The GMC Sierra 1500 AT4X was a joy to drive on the highway, but it was a direct blow to the dirt. Our terrain experience took us down into the desert on two tracks, through wide-open sand flushes, deep silt beds and through track ravines with massive vertical walls and narrow spaces. We also went down and then drove back up massive, rutted slopes. Right from the start, the Sierra 1500 AT4X showed that it is as happy to get out on tough trails as its smaller Colorado ZR2 cousin. The multimatic DSSV dampers sucked up bumps, falls and ruts with ease, and we never felt anything that could be misinterpreted as shock bleaching. With the exception of the largest desert, we found that the Sierra 1500 AT4X’s 9.84-inch front-wheel drive and 10.62-inch rear-wheel drive were perfectly suited for anything the desert had to throw at us as we burst through the sand water at speeds north of the freeway. legal.

As the experiment became more technical, the truck’s impressive terrain specifications came in handy. With 11.1-inch ground clearance, 25.5-degree approach angle, 23.0-degree departure angle and GMC’s optional mountain rails, the Sierra 1500 AT4X could easily navigate the toughest trails. (If you want a better angle, the Silverado 1500 ZR2 may be worth a look.) Of course, with an independent front suspension and relatively small 32.5-inch tires, we were not about to venture out on the trails full of Volkswagen-sized boulders, but that should be obvious. Although the front locking differential proved invaluable for climbing steep, tracky slopes, the rear locking differential was our favorite feature, as it can be engaged at any time (in two- or four-wheel drive) and used at any speed, as long as as the truck is in off-road mode.

Speaking of driving modes, the 2022 GMC Sierra 1500 AT4X is equipped with both off-road and off-road driving modes. Kind of like 2022 GMC Hummer EV, GMC’s off – road driving mode is intended for high – speed off – road driving, while its off – road driving mode is ideal for slow and technical driving. Both driving modes remove some of the electronic nannies, in addition to adjusting the throttle, shift strategy and steering feel. The off-road mode takes things a little further and allows “single pedal driving”, which means that the truck handles the braking, which allows the driver to focus on steering and acceleration. We thought that the terrain was most effective when crawling up or down slopes and over rocks. Useful in high or low range, the off-road driving mode acts as a kind of false low range by pulling the friction brakes. This allows great control when going down slopes and requires a large amount of throttle to start moving, which effectively dampens sudden and unintentional force commands (aka: throttle). The new terrain driving mode makes the hill control obsolete in practice, but the Sierra 1500 AT4X is still equipped with this feature as well.

The name of the terrain game is control, and the Sierra 1500 AT4X plays it very well overall. The multimatic DSSV dampers control the suspension movement well, and the truck’s new driving modes work well to control throttle and braking, and the front and rear locking differentials handle wheel spin on soft or loose surfaces. We could push the AT4X quite hard and the truck always managed to keep calm.

Wait, how much does AT4X cost?

The 2022 GMC Sierra 1500 AT4X has a starting price of $ 77,395, which includes the destination and delivery fee of $ 1,695. It may seem a bit steep, but it’s worth noting that the Sierra 1500 AT4X comes with an interior that is very similar to that of the new Sierra 1500 Denali Ultimate, as well as the powerful 6.2-liter V-8 standard and the fantastic ( and expensive to manufacture) Multimatic DSSV dampers. By comparison, the 2022 GMC Sierra Denali Ultimate starts at $ 82,795.

If it’s still a little too rich for your blood, the 2022 GMC Sierra 1500 AT4 starts at just $ 64,845. However, you will sacrifice a lot of the inner comfort pieces, along with the trick suspension, in an attempt to lower the price. Selecting all the boxes will get the AT4 interior more specification with the AT4X, but will increase the request to about $ 70,000. If you are looking for a little more wheel travel and have $ 77k, you can instead choose a base 2022 Ram 1500 TRX or a well-equipped Ford F-150 Raptor.

Sierra AT4 vs. AT4X: What’s the difference?

Choosing between the GMC Sierra AT4 and the new AT4X can prove daunting for those less familiar with the world of off-road pickups. There are a few things that make up the $ 12,500 difference between AT4 and AT4X. First, the AT4X comes with all premium interior upgrades as standard. The AT4X only gets the 6.2-liter petrol V-8, but the AT4 is available with either the 6.2-liter V-8 or 3.0-liter Duramax diesel I-6 engine. AT4X comes with 32.5-inch Goodyear Wrangler Duratrac tires, and AT4 gets 32.0-inch Goodyear Wrangler Territory rolling stock. The AT4X gets more off-road hardware in the form of Multimatic DSSV dampers, electronic front and rear locking differentials and available mountain rails, while the AT4 is equipped with Rancho double-tube dampers and an automatic “G80” rear locking differential.

2022 GMC Sierra 1500 AT4X: Final Thoughts

We’re been big fans of GMC’s AT4 brand since its introduction 2019 Sierra 1500. Unsurprisingly, we have also been impressed by Multimatic’s DSSV dampers and off-road hardware included in Chevy’s Colorado and Silverado ZR2 pickups. Now that the AT4X has begun to take off into nature and we have had the opportunity to glide behind the wheel, we can finally say with authority that the 2022 GMC Sierra 1500 AT4X may just be the ultimate jack-of-all-terrain pickup. Not only does the AT4X drive fantastic terrain through all types of terrain, but it also has impressive ways of driving, fantastic interior comfort and technology, and a wonderful new exterior. If you’re looking for a truck that can really go anywhere and do anything, this is it.
