The Story
Heritage & Legacy
The Canyon nameplate returned to GMC's lineup in 2015 after a brief hiatus, with the AT4 trim joining in 2017 as part of GMC's push into premium off-road segments. It carries forward GMC's truck heritage while addressing the growing midsize pickup market.
Design Philosophy
GMC designed the Canyon AT4 with a focus on capability over flash, featuring functional off-road equipment and purposeful styling. The AT4 treatment adds genuine off-road hardware rather than just cosmetic upgrades, emphasizing substance over style.
The Driving Experience
Engine Character
The standard 3.6L V6 provides smooth, reliable power with adequate torque for most situations, while the optional 2.8L Duramax diesel delivers impressive torque and fuel economy. Both engines prioritize real-world usability over peak performance numbers.
Chassis Dynamics
The AT4's suspension tuning favors off-road capability with increased ground clearance and specialized shocks, though it remains composed on-road. The 4WD system includes low-range gearing and hill descent control for serious terrain.
Sound Signature
The V6 produces a subdued, workmanlike growl while the diesel offers a refined rumble characteristic of modern turbo-diesels.
Strengths & Tradeoffs
Defining Strengths
The AT4 variant delivers genuine off-road capability with its electronic locking rear differential, skid plates, and hill descent control. The suspension tuning strikes a good balance between on-road comfort and trail competence, making it one of the more capable midsize trucks for serious off-road work.
With up to 7,700 pounds of towing capacity, the Canyon AT4 punches above its weight class. The available 3.6L V6 provides adequate torque delivery for boat and trailer hauling, while the truck's size makes it more maneuverable than full-size alternatives in tight spaces.
Honest Tradeoffs
The cabin feels dated with hard plastics dominating most surfaces, and the infotainment system lags behind competitors in responsiveness and user interface design. For a truck approaching $40K+ when optioned, the interior doesn't feel premium enough to justify the price point.
While competent off-road, the Canyon AT4 isn't designed for performance driving on pavement. The suspension is tuned for utility rather than handling, and the truck's high center of gravity and long-travel suspension make it unsuitable for serious track work or spirited canyon driving.
Ideal Owner
Perfect for buyers who need genuine truck capability in a more manageable size, especially those who regularly venture off-road or need a capable towing vehicle for recreational activities.
