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)
