Sierra AT4’s Dark, Distinguished Appearance

Sierra AT4 builds off the bold, chiseled forms of the next generation Sierra and creates a personality of its own through several unique visual cues that enhance its confident, broad-shouldered stance with sophisticated, functional design elements.

The Sierra AT4 has a unique look driven by distinctive 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 Sierra’s bold, C-shaped LED lighting signature.

AT4 Off-Road Capability

Sierra AT4’s tall stance is also a sign of its off-road capability. Compared to other 2020 Sierras, the Sierra AT4’s suspension rides 2” higher, providing added ground clearance for off-road driving. Unlike aftermarket lift kits, Sierra AT4’s factory-installed suspension was fully designed and validated by GMC engineers, allowing it to deliver the refined ride quality and durability expected of a GMC.

Sierra AT4’s off-road chops don’t end there. Sierra AT4 models include four-wheel drive as standard equipment, with a two-speed transfer case that includes low-range four-wheel-drive gearing for when conditions turn extremely tough. Sierra AT4 also includes off-road tuned Rancho monotube shock absorbers, a locking rear differential, skid plates and hill descent control, which leverages anti-lock braking technology to provide a smooth, controlled descent in uneven terrain without the driver needing to repeatedly push the brake pedal.

Innovative Technology

The Sierra AT4 is equipped with innovative technology to both enhance capability and elevate driver confidence off-road. Some of these features include:

Traction Select System: allows the driver to choose from pre-set drive modes that have been tailored for a variety of different terrain or weather conditions. Selecting one of these modes adjusts Sierra’s transmission shift points, throttle mapping and other systems to optimize performance for the situation at hand.

Segment-first Multi-Color Head-Up Display: projects key, customizable vehicle data, including an off-road inclinometer, on the windshield in a 15-inch diagonal display. The off-road inclinometer shows the fore-and-aft tilt, front tire angle and left-and-right tilt.

Surround Vision: available on Sierra AT4 and provides the driver with a “bird’s eye” view through an overhead image on the infotainment screen and can prove useful when slowly maneuvering in tight quarters - be it within a parking garage or out on a challenging trail.

Versatile Cargo Capability

Sierra AT4 was designed from square one to get you and your gear – be it camping equipment, mountain bikes, motorcycles, or beyond – exactly where you need to go. The 2020 Sierra AT4 offers best-in-class cargo volume – 62.9 cubic feet on short-box models and 89.1 cubic feet on standard box models. Sierra’s available 5-foot, 8-inch pickup box offers more cargo volume than Ford or Ram’s 6.5-foot-long standard boxes.

With six unique functions and positions, MultiPro Tailgate is the most innovative pickup tailgate ever with six unique functions and positions, offering enhanced second-tier loading and load-stop solutions, and easier access to items in the box.
