Introduction: Comparing GMC AT4 and AT4X – Key Differences Explained
When it comes to tackling the great outdoors, GMC offers two distinct off-road trim levels that cater to different levels of adventure seekers.
The AT4 (All-Terrain Four-Wheel-Drive) and AT4X trims are designed to take your GMC vehicle’s capabilities to new heights, but they differ in several key areas.
In this comprehensive guide, we’ll explore the differences between the GMC AT4 and AT4X, helping you decide which one better suits your off-road and adventure needs.
GMC Models Offering AT4 and AT4X Trims
The AT4 trim level is available across GMC’s lineup of SUVs and trucks, including the Terrain, Acadia, Yukon, Canyon, Sierra 1500, and Sierra HD. However, the more extreme AT4X variant is exclusively offered on GMC’s truck models – the Canyon, Sierra 1500, and Sierra HD.
Key Features of the GMC AT4 Models
The AT4 trim slots in between the SLT/Elevation and Denali trims, providing a perfect balance of everyday refinement and off-road capability. While the specific features may vary across models, all AT4 vehicles come equipped with the following:
- All-Wheel Drive (AWD) or Four-Wheel Drive (4WD) system
- Rugged exterior styling with an AT4-specific grille and black-chrome accents
- Larger wheels and all-terrain or mud-terrain tires
- Skid plates for added underbody protection
- Hill Descent Control for improved traction on steep descents
Additionally, some AT4 models may include:
- Off-road-tuned suspension
- 2-inch lift for increased ground clearance
- Two-speed transfer case (trucks only)
- Locking rear differential (trucks only)
- Improved approach and departure angles
Performance Showdown: GMC AT4 vs. AT4X
When it comes to sheer performance, the AT4X models take things up a notch. For instance, the GMC Canyon AT4X is powered by an off-road-optimized TurboMax engine that delivers a class-leading 430 lb-ft of torque for a standard gasoline engine.
Enhanced Off-Road Capability
The AT4X trims are designed for more extreme off-road adventures, thanks to several exclusive upgrades. Arguably the most significant is the inclusion of Multimatic DSSV dampers, which provide superior ride comfort and control over rough terrain by using three spool valves to control damping.
Other notable off-road enhancements found on AT4X models include:
- Significant suspension lifts (e.g., 3-inch lift on Canyon AT4X)
- Ultra-wide track widths for improved stability (e.g., 66.3-inch track on Canyon AT4X)
- Front and rear electronic locking differentials
- Larger off-road tires (e.g., 32-inch Goodyear DuraTrac on Sierra AT4X, 35-inch Goodyear Territory MT on Sierra HD AT4X)
- Improved approach and departure angles
- Increased ground clearance (e.g., 11.1 inches on Sierra AT4X, 11.6 inches on Sierra HD AT4X)

Fuel Efficiency: GMC AT4 vs. AT4X – Which Is Better?
While the AT4X models offer superior off-road performance, they may sacrifice some fuel efficiency due to their more robust components and higher curb weights. For instance, the Canyon AT4 with the 2.7L Turbo engine is rated at 19 MPG city and 24 MPG highway, while the Canyon AT4X with the same engine drops to 17 MPG city and 23 MPG highway.
Price Comparison: Is GMC AT4 or AT4X More Affordable?
As you might expect, the added off-road capabilities of the AT4X trim come at a premium. For example, the 2023 GMC Canyon AT4X starts at $48,995, while the Canyon AT4 has a starting MSRP of $41,995 – a difference of $7,000.
Choosing Between the AT4 and AT4X
The choice between the AT4 and AT4X ultimately comes down to your intended usage and budget. If you plan on tackling light to moderate off-road trails and don’t need the extreme capabilities of the AT4X, the AT4 trim offers a excellent balance of on-road refinement and off-road prowess at a more affordable price point.
However, if you’re an avid off-road enthusiast who frequently ventures into rugged terrain, the AT4X’s advanced off-road technologies, increased ground clearance, and superior articulation make it the clear choice provided you’re willing to pay the premium.
