The all-new 2019 GMC Sierra AT4 made its debut at the New York Auto Show combining off-road capability with premium features. It proves that simply because a truck is ready to head off-road doesn’t mean it can’t boast a luxurious interior.
The Sierra AT4 has front and rear bumpers and a grille surround in body-color finishes while the grille gets a knurled texture and black chrome. The LED fog lamp bezels and fenders are also black chrome with a high-gloss black finish on the window trims, mirror caps, and skid plate. Red accents on the AT4 emblems and tow hooks finish the look
Inside, the AT4 has unique dark trims with a dark-tinted aluminum finish on the steering wheel, center stack, and sill plates. The leather seats are Jet Black with embroidered AT4 badging on the headrests and there are standard all-weather floor mats. It looks impressive, but there’s substance beneath the style.
The AT4 comes standard with a 2-inch suspension lift for extra ground clearance and four-wheel drive with a two-speed transfer case including low-range four-wheel drive. There are standard off-road Rancho monotube shock absorbers, a locking rear differential, and hill descent control.
Also standard are 18-inch wheels with all-terrain tires and Traction Select which offers preset drive modes optimized to various terrain and weather conditions. Available features include a multi-color head-up display, rear camera mirror, and safety features including surround vision, lane change alert with blind spot alert, front pedestrian braking, and low speed forward automatic braking.
Power comes from a choice of three engines. There’s a standard 5.3-liter V8 engine with the option for either a 6.2-liter V8 or 3.0-liter 6-cylinder turbodiesel. Both optional engines come paired to 10-speed automatic transmission.
The cargo box on the AT4 features a standard MultiPro tailgate as seen on the 2019 Sierra Denali and SLT. It has six functions and positions that give it incredible flexibility. It offers second-tier loading, a standing work station, and easy access to items in the box.
There’s 63 cubic feet for cargo in the short box, which is made with roll-formed, high-strength steel that’s 50 percent stronger than the current version. Later in the model year, the CarbonPro carbon fiber box will also be available on the AT4. It replaces the standard steel panels and floor with a lightweight carbon fiber for better scratch and corrosion resistance.
The all-new 2019 GMC Sierra AT4 is set to go on sale this fall.
