GMC redefines the off-road space by introducing the new 2021 GMC Sierra 1500 AT4 truck. The GMC Sierra AT4 delivers a unique formula of authentic off-road capability and innovative technology paired with premium refinement and a bold appearance expected from GMC.

“Sierra AT4 is designed for the customer who wants an elevated presence on the road and the capability to venture off life’s beaten path,” said Duncan Aldred, vice president of Global GMC.

Building on the commanding presence of the next-generation 2021 Sierra, the new Sierra AT4 enhances its confident, broad-shouldered stance with sophisticated, functional design elements that support its off-road capability, perfect for Minnesota’s harsh driving conditions.

Standard features on the 2021 GMC Sierra 1500 AT4 include:

  • 2-inch factory-installed suspension lift
  • Standard 4WD with a two-speed transfer case, locking rear differential and skid plates
  • Off-road-tuned Rancho monotube shock absorbers
  • 18-inch wheels with all-terrain tires or available mud terrain-rated Goodyear Wrangler Duratrac tire, or available 20-inch wheels with all-terrain tires
  • Exclusive wheel design with machined-face, dark-tinted appearance
  • Hill Descent Control
  • Traction Select System
  • GMC exclusive, industry-first MultiPro Tailgate
  • Black chrome finish on the fog lamp bezels, fender surround and grille insert
  • Body-color grille surround, door handles and bumper
  • Exclusive athletic interior trim elements
  • Red vertical recovery hooks
  • Standard 5.3L V-8 engine

The GMC Sierra AT4 has a unique look driven by dark exterior finishes and modern detailing. The front and rear bumpers and the grille surround are finished in body color, while the bold grille design with its rugged, knurled texture is finished in black chrome set off by the Sierra’s bold, C-shaped LED lighting signature.

Additional accent details such as the LED fog lamp bezels and fender trim continue the use of black chrome, while a premium high-gloss black finish is applied to the window trim, mirror caps and skid plate. Touches of red complete the package and make the AT4 stand out with subtle detailing in the Sierra’s all-new AT4 signature emblems and bold, unique vertical tow hooks. The exterior details create a distinct and modern personality for the AT4 that projects GMC confidence and capability.

The interior also carries AT4-specific darkened trim, including dark-tinted and textured aluminum finishes on the steering wheel, center stack and sill plates, as well as a unique Jet Black/Kalahari color accents in the seats and live stitching. Leather-appointed seating with embroidered AT4 badging on the headrests and all-weather floormats are standard and support our customers’ active lifestyles and AT4’s mission of delivering capability with uncompromising durability and comfort, perfect for facing Minnesota weather and road conditions.

Eric Stafford of Car and Driver Magazine says this of the 2021 GMC Sierra 1500: “they look great in the valet lane or out on the trail.”

GMC Sierra AT4 comes standard with a factory installed 2-inch suspension lift that provides additional ground clearance and four-wheel drive with a two-speed transfer case that includes low-range four-wheel-drive gearing for extremely tough conditions.

The GMC Sierra AT4 also includes standard off-road tuned Rancho monotube shock absorbers, a locking rear differential and Hill Descent Control, a driver assistance feature that leverages the anti-lock braking system to enable smooth, controlled descents on steep grades without the driver having to touch the brake pedal under certain conditions. The locking rear differential directs engine power equally to both rear wheels for the greatest traction on slippery or uneven terrain.

The Sierra AT4 boasts innovative technologies that optimize capability and elevate driver confidence.
