Meet the 2019 GMC Sierra AT4: Lifted and loaded

General Motors introduced an off-road capable variant of its 2019 GMC Sierra pickup truck, called the Sierra AT4, in advance of the New York International Auto Show on Monday.

The company says the AT4 sub-brand will be extended to GMC's entire lineup in the next two years. The alphanumeric name denotes Sierra's off-road-ready package, which features a 2-inch suspension lift, a locking rear differential, skid plates and a set of off-road-tuned Rancho monotube shocks. Mud terrain-rated Goodyear Wrangler DuraTrac tires or 20-inch wheels with all-terrain tires also will be available. The AT4 also includes helpful electronics such as hill descent control and GMC's Traction Select System.

Of course, there are a lot of extra boxes you can check when you order your Sierra AT4 - you can replace the 5.3-liter V8 with the more potent 6.2-liter gas burner or the new 3.0-liter I6 diesel.

Based on the new 2019 Chevrolet Silverado, the GMC Sierra (including the AT4 model) looks to stand out from its corporate cousin in terms luxury touches, along with some subtle exterior details. Dark tinted and textured aluminum trim can be found on the steering wheel, center stack, and sill plates.

Just as the Denali subbrand has helped GMC lure more upscale buyers, the brand is counting on the new AT4 subbrand to draw off-road enthusiasts who might not consider GMC or defect to another light-truck brand, such as Jeep.

The 2019 Sierra AT4 means business when it comes to going off-road. 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. 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.

It added that the teen had "surpassed all locked doors and gates and proceeded to ride his skateboard through school grounds". He also conceded some resentment toward Nikolas for being "the favored brother", according to the report.

Surround Vision is available on Sierra AT4 and provides the driver with a bird's-eye view through an overhead image on the infotainment screen. Red accents are added to the emblems and front tow hooks.

That's where the AT4 comes in. Either way, the short box gets 63 cubic feet of storage space. On the gas side, there's both the 6.2-liter and 5.3-liter V8 engines.

The V-8 engines feature stop-start technology and GM's 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.

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.
