Compare 2025 GMC Sierra AT4 Vs. AT4X Trims & Features

Purchasing your next off-road vehicle gets much easier once you know the differences between the GMC Sierra 1500 AT4 vs. AT4X. The GMC Sierra 1500 AT4 is the ultimate pickup for going off the beaten path, offering an 11.1-inch ground clearance, up to 9,000 pounds of towing capacity,¹ and dozens of safety and convenience features to make tackling the roads less traveled straightforward. However, once you try the AT4X at DeVoe Buick GMC, you'll see just how comfortable off-road travel can be, thanks to added 16-way front-row seats, a standard Head-Up Display, and a Bose® Premium Series 12-speaker sound system.

Let's examine how these two vehicles differ and what they have in common. Then, you can come to our lot for a tour and a test drive.

2025 GMC Sierra 1500 AT4 vs. AT4X Exterior & Design Features

The GMC Sierra 1500 AT4 exemplifies bold and durable style. Its high lift and 11.1 inches of ground clearance stand tall over the competition, while a grill stands clear above its sturdy, damage-taking bumper. A rectangular and well-constructed frame lets the AT4 look dominant as it conquers heavy trails.

The GMC Sierra 1500 AT4X has many stable features similar to the AT4 that make it so notable but adds the AEV bumper with in-built winch support. With other available AEV products, like the underbody skid plate or steel rear bumper, you'll have an armored behemoth ready to traverse some of the most daunting challenges that nature can throw.

2025 GMC Sierra 1500 AT4X vs. AT4 Interior Features

Your interior continues this promise of durable majesty. As a high-level trim of the new GMC Sierra 1500 for sale, the AT4 comes standard with dozens of convenient options, like the in-vehicle trailering app, keyless open and start, a ventilated driver's seat, heated rear seats, an HD Surround Vision Camera, dual-zone automatic climate control, and much more! Leather seats bring refined comfort in both options.

The AT4X raises the bar even further. With a standard Bed View Camera, Head-Up Display, Universal Home Remote, and Bose® Premium Series 12-speaker sound system, the AT4X's cabin is a state-of-the-art masterpiece. You'll even be able to get a massage via the 16-way powered front seat as you take on trails or your daily commute.

GMC Sierra 1500 AT4 vs. AT4X Specs & Performance

While the AT4X leads in terms of standard comfort features, the performance of these two models is quite even. The AT4X has a greater payload capacity when comparing the two models with a short bed, but they also share engine options and the same amount of cargo bed volume. See more details below:

While the AT4 uses the same engine as the AT4X, it can come out with potent specs. For example, the AT4 can come with a short or standard bed, while the AT4X is locked to a short bed. This gives you more cargo capacity to work with while preserving the impressive MPG ratings of the AT4. The AT4 also has a higher towing capacity compared to the AT4X.

The spacious crew cab remains the same between the two trims. Whether you climb into an AT4 or AT4X, you can relax in over 43 inches of front headroom, more than 44 inches of front legroom, a 40.12-inch rear head space, and 43.4 inches of legroom for rear passenger seats.

That difference in performance is because of the expressive suspension and protective features of the AT4X, like the full-locking front and rear differential. This goliath of the trail utilizes an array of evolutionary features, like the highlights you'll see below, to become a paragon of weekend excursions.

GMC Sierra 1500 AT4 vs. AT4X Safety

Both models have Lane Keep Assist, Lane Departure Warning, Automatic Emergency Braking, and Safety Alert Seat systems by default. You can connect to OnStar® Basics for remote services, including Automatic Crash Response, to get immediate aid in an emergency. Your upgrade options are also high-end.
