2019 GMC Sierra AT4 Heads off the Beaten path in New York

When GMC unveiled the 2019 Sierra 1500 pickup earlier this year, GM’s upscale truck-and-SUV brand focused on materials, cabin tech and one seriously interesting tailgate. But what about fans of off-roading? GMC’s got just the truck for you at the 2018 New York Auto Show.

The 2019 GMC Sierra AT4 is a trim level built for venturing off paved roads. It packs a number of upgrades to that end, including a 2-inch suspension lift, off-road-tuned Rancho monotube shocks and a standard 4WD system with a two-speed transfer case, a locking rear differential and skid plates.

Buyers can opt for 18-inch wheels shod in all-terrain tires or 20-inch wheels with similar tires, but if that isn’t enough, mud-ready Goodyear Wrangler Duratrac tires are on offer, as well. And yes, GM’s wild MultiPro recursive tailgate is also standard.

Under the hood is a 1.5-liter I4 operating on the Atkinson cycle. It mates to an electric motor to produce a net 151 horsepower and 197 pound-feet of torque. Its lithium-ion battery, sandwiched under the rear seat, isn’t enough to produce plug-in-like range. Instead, it operates as a series hybrid (like, say, the Prius), providing electricity to the wheels or the battery pack as it sees fit. Paddles on the steering wheel let drivers select between three different strenghs of regenerative braking. Honda estimates a city fuel economy of 55 mpg.

Aesthetically, the AT4 gets a bunch of dark exterior trim with body-color bumpers and grille surrounds. High-gloss black covers the window trim, mirror caps and skid plates, and a few dashes of red (including those tow hooks) add a splash of color to break things up. Inside, there’s dark trim yet again, with textured aluminum offering a bit of variety alongside AT4 badges embroidered in the headrests.

If that’s not enough for you, there are plenty of options boxes to check off, as well. You can add a color head-up display (a first in this segment), a mirror that shows what the backup camera sees and a carbon fiber bed. There is a small handful of safety features on offer, as well, like autobrake and blind spot monitoring.

GM’s 5.3-liter V8 is standard, but like other Sierra trims, a 6.2-liter V8 and a new 3.0-liter diesel I6 are both available. The 2019 GMC Sierra AT4 goes on sale in the fall, and pricing will be announced closer to that time.
