Powertrain Options

For the 2022 model year, the AT4 features an impressive standard diesel engine offering, the 3.0L Duramax Turbo-Diesel, which makes a best-in-class 277 diesel horsepower, while the brawnier AT4X comes with a 6.2L V8 for a power upgrade. Both engines are rugged and capable with reasonable arguments for both sides. If you’re a diesel enthusiast looking for big towing power at low rpms and for more power overall, the V8 is the obvious choice. Note that no diesel option is available for the AT4X, while the 6.2L V8 is available on the AT4.

Technical Edge

Off road thrill seekers looking for an edge on the competition can look to the AT4X and its front and rear locking e-differentials, the only pickup in its class with that technology. This means when the Sierra ATX4 is in a low traction situation, such as treading through mud or grave,l and it needs traction, this system will engage and distribute power where it is most needed. Other features to give you an advantage over the competition include a two speed transfer case (also standard on the AT4) for precise control through various terrains and the AT4X exclusive new Multimatic DSSV Dampers and Shocks, helping keep your premium ride smooth and cabin silent.
