GMC has unveiled the 2019 GMC Sierra AT4, the more off-road ready version of the all-new 2019 Sierra.

The AT4 package is positioned to lure customers away from competitors that have been raking in cash in recent years, such as Fiat Chrysler's successful Jeep brand, and the somewhat unexpectedly popular Ford Raptor off-road pickup, which began with a small team within Ford working with a modest budget. Off-road tuned Rancho monotone shock absorbers, a locking rear differential, and Hill Descent Control are all included as standard. The Sierra AT4 comes standard with the MultiPro Tailgate and is available with the carbon fiber box that each debuted on the 2019 Sierra.

The AT4 will feature technology that aids its off-road mission, including the Traction Select System, which adjusts the vehicle's stability control program, throttle mapping and transmission shift points to tailor the truck's performance to driver-selected terrain or weather conditions.

Buyers can choose from 5.3- and 6.2-liter V8 engines or the new Duramax 3.0-liter turbodiesel inline-six.

Exterior changes to the Sierra AT4 include black chrome on the front grille, fog lamp bezels and fender trim.

At its exterior, GMS has given a high-gloss black finish on the window trim, skidplate, and mirror caps. GMC outfitted the Sierra AT4 with a 2-inch lift, much like Chevy did with the 2019 Silverado Z71.

GMC has announced the 2019 Sierra AT4. The interior includes darkened trim, textured aluminum finishes, and leather-appointed seating. A head-up display offers information including an inclinometer - showing fore and aft tilt, front tire angle, and left and right tilt - on the windshield. Available surround vision provides a bird's-eye view of the vehicle's surroundings when maneuvering in tight spots. Eighteen-inch wheels with all-terrain tires are standard. Thanks to added tie-down hooks located in the corners and center bulkhead, and new centralized LED lighting, the task of loading and securing motorcycles and bikes has never been easier. The truck gets a bunch of cool new features, a new diesel engine option and a carbon fiber composite. Either way, the short box gets 63 cubic feet of storage space. Both optional engines use the new 10-speed automatic to transfer power to the rest of the drivetrain.

The 5.3L and 6.2L engines feature stop/start technology and new Dynamic Fuel Management that enables the engine to operate on one to eight cylinders, depending on demand, to optimize power and efficiency.

With a strong foundation of manufacturing trucks since 1902 and now selling in a dozen countries across the world, GMC offers purpose-built vehicles designed and engineered to the highest standard.
