GMC Sierra AT4 Launches Sub-Brand

Meet the 2019 GMC Sierra AT4: Lifted and loaded

The 2019 GMC Sierra AT4 blends off-road hardware into a modern, thoroughly updated pickup truck that doesn't skimp on power, luxury, or safety equipment.

GMC is going further into the off-road truck segment with the 2019 GMC Sierra AT4, a slightly more in-depth off-roader than the previous Sierra All-Terrain model, but not quite a Ford F-150 Raptor competitor.

The MultiPro Tailgate first seen on the 2019 Sierra Denali and SLT - which opens in six different positions - is included on the 2019 Sierra AT4 as standard.

Other standard AT4 features include off-road-tuned Rancho monotube shock absorbers, a locking rear differential and Hill Descent Control, a driver-assistance feature that leverages the antilock braking system to enable smooth, controlled descents on steep grades without the driver having to touch the brake pedal under certain conditions.

In the Sierra's case, the AT4 model is immediately recognizable with body-colored and black chrome accents. Of course not. And here it is: the 2019 GMC Sierra 1500 AT4.

Look for the 2019 GMC Sierra AT4 to arrive in dealerships later this fall with pricing announced closer to its on-sale date.

The interior of the AT4 adds a luxurious finish to the tough-as-nails exterior design.

The Sierra's head-up display projects an off-road inclinometer onto the windshield, including the fore-aft tilt, front tire angle and left-right tilt. The ProGrade Trailering System and related smartphone app also will be optional, as will 360-degree camera function displayed on the multimedia screen.

Being based on the redesigned 2019 Sierra 1500, the truck is also avilable with the new CarbonPro carbon fiber box. Off-road traction is compounded by 32-inch Goodyear DuraTrac off-road tires mounted to custom 18-inch wheels. 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. It replaces the standard steel inner panels and floor with a lightweight carbon-fiber composite that is 62 pounds lighter than the steel version. A 110V outlet in the rear routes power to the tools and supplies needed for a day at the track or on the trails.

Sierra AT4 features new versions of the proven 6.2L and 5.3L V-8 engines along with all-new Duramax 3.0L inline-six turbo-diesel engine. Both the 6.2-liter and the diesel get a 10-speed automatic.

GMC will sell a new line of off-road packages for its trucks and SUVs that aims to take advantage of recent enthusiasm for dirt-worthy utility vehicles as the overall consumer shift toward SUVs and trucks continues unabated.
