The Canyon AT4X sports a wide stance, factory lift, and aggressive rubber. All of which telegraph purpose before you even climb into it. GMC didn’t just bolt on an off-road look here. It engineered capability into the bones.
You get a factory lift, an ultra-wide track, and real hardware like underbody protection and locking differentials.
Under the hood is GM’s now-familiar 2.7-liter TurboMax inline-four, putting down 310 horsepower and 430 lb-ft of torque. It’s my only complaint about this truck. Not for its capability or output, but for its sound. Which is clackety at best and disconcerting the rest of the time.
Torque comes on early and strong, exactly where you want it when crawling over rocks or pulling yourself up a loose incline. It’s less about drama, more about control. On pavement, it’s quick enough, but it’s not trying to win stoplight races. This engine is about usable muscle, not bragging rights.
The AT4X earns its badge the moment the pavement ends.
Front and rear electronic locking differentials, Multimatic DSSV dampers, and serious ground clearance turn this into one of the most capable, off-pavement midsize trucks you can buy right now. There’s a composure to how it handles rough terrain. Where lesser trucks bounce, the AT4X settles. Where others scramble for traction, this one just walks through it.
It also helps that GMC built in actual tools for off-road driving: terrain modes, underbody cameras, and real-time performance displays that show pitch, roll, and articulation.
Daily driving and interior comfort are where compromise happens.
Step inside and things shift. The AT4X tries not to abandon comfort in pursuit of capability. There’s a large 11.3-inch touchscreen, a digital gauge cluster, and enough tech to make daily driving feel modern.
Interior materials lean upscale for the segment, and the layout is intuitive without trying too hard to be futuristic. It’s a truck interior that understands its audience: be functional first, but not spartan. It mostly succeeds, but with compromises in roominess and seating comfort.
Ride quality is firm, but not punishing.. but always reminding you there’s serious suspension hardware underneath. Fuel economy hovers around 19 mpg combined, which feels about right given the weight and capability. And while it can tow up to 7,700 pounds in some configurations, the AT4X leans more toward trail duty than worksite hauling.
This is not the Canyon you buy for commuting alone. It’s the one you buy because your weekends demand more.
The 2026 GMC Canyon AT4X is one of those rare vehicles that feels unapologetically focused. It’s not trying to be the most efficient, the cheapest, or even the most comfortable midsize truck. It’s trying to be the one you trust when the road disappears.
And in that role, it’s excellent.
If your idea of a good time involves ruts, rocks, and questionable decision-making, the AT4X encourages those things.
