2019 GMC Sierra AT4 Explained – Video

2019 GMC Sierra AT4 Explained – Video

Building on the commanding presence of the next generation 2019 Sierra, the new Sierra AT4 enhances its confident, broad-shouldered stance with sophisticated, functional design elements that support its off-road capability.

“The 2019 Sierra is the boldest expression ever for GMC’s full-size pickup, and the new AT4 reinforces its essence of capability with distinctive, athletic cues,” said Matt Noone, director of design, GMC Exteriors. “From every angle, it conveys GMC’s premium yet functional design language.”

The Sierra AT4 has a unique look driven by dark exterior finishes and modern detailing. The front and rear bumpers and the grille surround are finished in body color, while the bold grille design with its rugged, knurled texture is finished in black chrome set off by the Sierra’s bold, C-shaped LED lighting signature.

 

 

Additional accent details such as the LED fog lamp bezels and fender trim continue the use of black chrome, while a premium high-gloss black finish is applied to the window trim, mirror caps and skid plate. Touches of red complete the package and make the AT4 stand out with subtle detailing in the Sierra’s all-new AT4 signature emblems and bold, unique vertical tow hooks. The exterior details create a distinct and modern personality for the AT4 that projects GMC confidence and capability.

The interior also carries AT4-specific darkened trim, including dark-tinted and textured aluminum finishes on the steering wheel, center stack and sill plates, as well as a unique Jet Black/Kalahari color accents in the seats and live stitching. 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.

Sierra AT4 comes standard with a factory installed 2-inch suspension lift that provides additional ground clearance and four-wheel drive with a two-speed transfer case that includes low-range four-wheel-drive gearing for extremely tough conditions.

Sierra AT4 also includes standard off-road tuned Rancho monotube shock absorbers, a locking rear differential and Hill Descent Control, a driver assistance feature that leverages the anti-lock braking system to enable smooth, controlled descents on steep grades without the driver having to touch the brake pedal under certain conditions. The locking rear differential directs engine power equally to both rear wheels for the greatest traction on slippery or uneven terrain.

The Sierra AT4 boasts innovative technologies that optimize capability and elevate driver confidence.

Sierra AT4 features new versions of the proven 6.2L and 5.3L V-8 engines along with all-new Duramax 3.0L inline-six turbo-diesel engine. The available 6.2L and 3.0L engines are paired with a 10-speed automatic transmission.

The 5.3L and 6.2L engines feature stop/start technology and new Dynamic Fuel Management that enables the engine to operate on one to eight cylinders, depending on demand, to optimize power and efficiency.

The GMC Sierra AT4 goes on sale this fall.
