For ages, when it came to the GMC Sierra and Chevy Silverado, their biggest distinctions were that the GMC often had a luxurious Denali model, whereas the Chevy often had a more off-road-ready model the GMC lineup lacked. With the new-generation Sierra and Silverado distancing themselves from each other, General Motors must feel there is a large enough gap for the Sierra to have an off-road-prepped model too. And here is that model: the 2019 GMC Sierra AT4.
The 2019 Sierra AT4 starts with a darkened effect that includes dark exterior finishes, and body-colored bumpers and grille surround. There is also a black-chrome grille with a knurled texture. Other exclusive details include black-chrome fog light surrounds, and gloss-black window trim, mirror caps and skid plate.
Inside the darkening continues with dark-tinted and textured aluminum finishes on the steering wheel, center stack, and sill plates. There are also Jet Black/Kalahari-colored, leather-wrapped seats with embroidered AT4 badges.
While the stylistic upgrades are great, what really makes the AT4 are its off-road upgrades. These enhancements include a 2-inch factory suspension lift, standard four-wheel drive with a two-speed transfer case, off-road Ranchero monotube shocks, 18-inch wheels wrapped in all-terrain or mud-terrain tires, hill-descent control, red recovery hooks, Traction Select System, and the ProGrade Trailering System with Trailering App,
Pricing is not available yet, but the 2019 Sierra AT4 will hit showrooms in the fall of 2018.
