Earlier this month, the [all-new GMC Sierra](<https://www.thedrive.com/new-cars/18910/the-2019-gmc-sierra-raises-the-bar-for-premium-pickup-trucks>) made its debut in Detroit. We were very impressed by its classy new look, its trick tailgate, and its available carbon-fiber bed. GMC has done an excellent job standing out in a field of trucks that’s getting increasingly competitive.

But what we saw in Detroit was just the range-topping Denali and almost-as-nice SLT versions of the new Sierra. This time, at Pier 36 in Manhattan, GMC unveiled the all-new Sierra AT4.

The 2019 GMC Sierra AT4 is the first offering from an all-new sub-brand from GMC. AT4, which stands for [All Terrain](<https://www.thedrive.com/article/5909/does-the-2017-gmc-acadia-all-terrain-live-up-to-its-name>) 4, is all about off-road ability and attitude without sacrificing the premium features and technology you expect from GMC. These are trucks for the driver who wants to go off the beaten path in a full-size pickup truck but wants to do it in pebbled leather seats with a full-color head-up display.

The truck looks distinctly different from the Denali and SLT Sierras we saw in Detroit earlier this month. Sierra AT4 features include a rugged, yet tasteful two-inch lift, a locking rear differential, skid plates, hill descent control, a traction select system, optional Goodyear Wrangler off-road tires, and of course, red recovery hooks in front to let everyone know what a [serious off-roader](<https://www.thedrive.com/article/16306/gmc-sierra-all-mountain-concept-to-debut-at-vail-mountain>) it is. The HUD in the Sierra AT4 has an off-road inclinometer showing the fore and aft tilt, front tire angle, and left and right tilt.

Power comes from a standard 5.3-liter V8. If you want some more grunt from your Sierra AT4, you can upgrade to a 6.2-liter V8. There's also a 3.0-liter inline-six turbo-diesel option. Being an off-road model, four-wheel drive is standard. The 6.2 and 3.0 engines come equipped with a 10-speed automatic transmission.

We're looking forward to seeing what else GMC has in store for the new AT4 subbrand. If AT4 can do what [Denali](<https://www.thedrive.com/article/17668/almost-one-third-of-all-gmc-models-sold-are-denalis>) did in increasing transaction prices and making up a good chunk of the brand's sales volume, then GMC could have another cash cow on its hands. The 2019 GMC Sierra AT4 will arrive in early 2019.
