GMC has redefined off-road driving by introducing the new GMC AT4 off-road all-capable series for 2022.

The best incarnation of this uniquely designed and made desert mobiles is the 2022 Sierra AT4, which is available in crew and regular cab models designed exclusively for the Middle East region.

Building on the strong presence of the 2022 Sierra, the new Sierra AT4 enhances its confident and broad stance with advanced and practical design elements that underpin its off-road capabilities.

The Sierra AT4 has a unique look based on darker exterior finishes and modern details.  The front and rear bumpers and grille surround feature body-colored design accents, while the bold grille design with its rough and grooved texture is accented with black chrome-accented by the bold design of the C-shaped LED lamps.

Additional design-enhancing details include black chrome on the LED fog lamp bezels and fenders, while high-gloss black paint is applied to the window frames, exterior mirror caps, and fender panels.  The red accents complement the ensemble and make the AT4 stand out from the crowd on the road with elegant detailing on the Sierra's all-new AT4 badges and unique, perpendicular towbars. 

Exterior details create a unique and modern character for the AT4 that reflects GMC's levels of confidence and capability.

The interior is distinguished by the AT4-specific dark livery, including darkened and drilled aluminum accents on the steering wheel, center console, side sills, and unique dark black/Kalahari accents on the seats with prominent stitching.

Genuine and faux-leather seats with an embroidered AT4 logo on the headrests and all-weather floor mats are standard equipment that supports customers' active lifestyles and supports AT4's mission to deliver capability without compromising durability and comfort.

Real off-road capabilities

The 2022 Sierra AT4 comes factory-equipped with a standard two-inch suspension lift, providing additional ground clearance and all-wheel-drive capability with a two-speed transmission that includes a short-haul four-wheel clutch in extreme conditions.

The Sierra AT4 also features standard off-road Rancho-tuned monotube shocks, a locking rear differential, and hill descent control, and a driver-assist feature that relies on the antilock brake system (ABS) to enable smooth and unobtrusive downhill slopes with control — the driver being forced to use the brake pedal in certain circumstances. 

A locking rear differential directs engine power parallel to the two rear wheels for optimum traction on slippery or uneven terrain.

The Sierra AT4 features innovative technologies such as the Traction Selection system that allows the driver to select from preset driving modes customized for different terrain or weather conditions to enhance capabilities and increase driver confidence.  Choosing one of these modes adjusts Sierra's transmission shift points, throttle mapping, and StabiliTrak system to optimize performance according to the driver's situation.

The new 2022 Sierra AT4 comes equipped with the industry-first standard MultiPro Tailgate — the most innovative tailgate ever.  The MultiPro Tailgate features six unique functions and positions that allow for enhanced secondary loading with load-stop solutions, a working platform, and easy access to items in the box.

In terms of the space and storage that are critical to customers, the 2020 Sierra AT4 offers innovative solutions.  The trunk provides the storage capacity of 1,784 liters in the short-lived trunk, which is made of high-strength coiled steel, while the redeveloped alloy offers 50 percent more strength than the current model.

The optional GMC rail accessories included in the box allow you to quickly and easily install or adjust bike platforms, rowing boat carriers, and other accessories.  The compact location of the rails makes the cargo more accessible and reduces the amount of space used in the rest of the box.

 In addition to all this, the backs of the rear seats can be folded down to reveal two rectangular storage spaces of 10 liters, which are large enough to accommodate tablets, cables, and other personal accessories, in addition to the presence of a large storage platform with a capacity of 24 liters under the second row of seats where all equipment can be stored.

The driver is steadily on the move

 The Sierra AT4 features two new engines: a 5.3L V-8 and a 6.2L V-8.  The 6.2L engine is mated to a 10-speed automatic transmission.

While the Sierra regular cab features 5.3L V8 engines with active fuel management and a six-speed automatic transmission, the powertrain on Crew and Double Cab models includes stop/start technology and drivetrain. The new Dynamic Fuel Management enables the engine to run on two to eight cylinders, depending on demand, for enhanced power and efficiency.

Following the huge popularity of the new Sierra AT4 pickup truck, as well as the recently launched Acadia AT4, the Yukon AT4 is now focused on off-road adventures. The 2022 Yukon AT4 features upscale, adventure-inspired design touches to match its rugged capabilities. 

The first-ever Yukon AT4 features a unique front end that visually gives off a rough, all-terrain appearance and supports off-road capabilities. The AT4 features Air Ride Adaptive Suspension on all four corners so the vehicle can be raised and ground clearance increased by two inches (50mm). 

At this maximum altitude, the Yukon AT4 has an approach angle of approximately 34 degrees for enhanced off-road capabilities.  The AT4 also contrasts the Denali look with chrome accents on the exterior, with special features accentuated by body color or darker trim around the sides, as well as a pair of Sierra AT4-style red intake stops.
