Luxury truck or SUV? » LATEST NEWS »

When the Silverado ZR2 arrived for the 2022 model year, it was almost expected that GMC would bring a sleeker version to market. Now with the 2023 AT4X, that idea has become a reality.


One thing that really sets AT4X apart from other high-end SUVs is the understated exterior. Yes, there are some telltale signs like the Duratrac tires and rock rails, but overall the AT4X looks just like the AT4. There’s no crazy exterior graphics or wide body cladding to distinguish the 2023 AT4X from a regular AT4, and we like that.

Up front is a large black GMC grill with a chrome red GMC badge. Of course, the tow hooks are red, which means this is an off-road vehicle. In the lower driver’s side of the grill sits an AT4X badge, which is really the only signal from the front.

As you move down the page, there are two badges here. On the upper front fender is a 6.2L V8 badge and on the lower driver’s door is an AT4X badge. The 32-in Goodyear Wrangler Duratracs wrap around 18-inch gloss black 12-spoke aluminum wheels.

Around back sits the Multi-Pro tailgate with Kicker sound system. Below is the corner bumper ladder, which is one of our favorite features for accessing the bed. There is an AT4X badge on the lower right corner of the tailgate that indicates what this truck really is.

The final AT4X logo on the outside is molded into the front of the bed. Speaking of the bed, we love GM truck beds that have optimized space with a significant amount of tie-down options.


Inside, the AT4X is top tier. GMC’s new interior is excellent and works well here. The infotainment screen and center console are oriented towards the driver for ease of use. There are physical buttons for climate control and volume, but no tuning dial.

Included on the 2023 AT4X are heated, ventilated and massaging front seats, heated outer rear seats, a head-up display, trailer camera cables and a rearview mirror. It’s almost a Denali Ultimate inside.

At the bottom of the center stack are nine rocker switches. These control everything from lane keeping assistance and auto stop start to downhill and differential lock. Although there are many gears overall, they are laid out in an easy-to-use manner.

The seats are comfortable and spacious both front and back. The rear is so spacious that an adult can pass between a rear-facing child seat and the front seats with little effort.

Of course, the most capable SUV in GMC’s lineup needs massaging seats. They are a must on the track. In all seriousness, the many standard features of the AT4X are very nice. On the other hand, many people do not want them and would prefer a more budget-friendly option. Because this exists Silverado ZR2, but even then it is very well equipped. Those looking for a more budget-friendly option may need to take a look Colorado ZR2 or Frame Tradesman Power Wagon.

Run AT4X

On the way

On pavement, the 2023 AT4X is very agile and comfortable. Multimatic’s DSSV dampers tend to perform well in all situations. As the quote goes, a jack of all trades is no master, but still better than a master. They provide a good off-pavement ride without sacrificing road stability. However, they cannot hide their off-road ability. Compared to the magnetic ride control shocks on the Denali Ultimate, the road ride is not as controlled. There is a bit of fluid feel and lean in the corners. Part of this is because the tires have more sidewall, but the shocks play a big part in that.

Power is big from the 6.2-liter V8 with 420 horsepower and 460 ft-lbs of torque. A well-tuned 10-speed gearbox is the only option. Getting up to speed and passing at highway speeds are non-issues. Hill braking is also built in where the transmission downshifts to slow the vehicle on long hills, reducing brake wear.

AT4X is big, but not as extreme as Raptor and TRX. This pays off both around town and on narrow paths. Tight parking stalls and narrow lanes require extra effort, but we had no problems.

Off the sidewalk

Going off the beaten path is where the DSSV shocks really shine. Up front, the independent suspension limits travel, but the shock absorbers make up for this very well. Somehow the shock absorbers are tuned so that topping and bottoming them out is very smooth and in a controlled manner. Driving over larger bumps at high speeds can cause a wheel to leave the ground. In this scenario, both the takeoff and the landing are so smooth that it is hard to notice that the tire was ever in the air.

Being smaller than the Raptor and TRX helps the AT4X on tighter trails. Even the introduction of the front cabinet is beneficial in certain situations. We never struggled to climb anything in our tests with the competition, but it’s nice to have that option.


With a base MSRP of $77,500, the 2023 GMC AT4X is very well equipped. Our tester had two options, the $495 Desert Sand Metallic paint and the $1,195 rock rails. Adding the $1,795 destination charge brings the total to $80,935. Compared to one Ford Raptor or Frame TRX AT4X is in the ballpark. But when equipped with similar interior features, the AT4X comes in a bit smaller than the other two.


To answer the question in the title, yes the 2023 AT4X is a luxury truck and yes it is an off-road vehicle. GMC tends to produce similar models to Chevy but with added luxury. The AT4X does this with the already well-equipped Silverado ZR2. The top dog for interior luxury in GM’s truck lineup remains it Denali Ultimate, but AT4X is not far from it. On the other hand, the AT4X and Silverado ZR2 are the only half-ton trucks that come with front and rear locking differentials.
