DARK, DISTINGUISHED APPEARANCE
Sierra AT4 builds off the bold, chiseled forms of the Next Generation 2019 Sierra, and creates a personality of its own through a number of unique visual cues that enhance its confident, broad-shouldered stance with sophisticated, functional design elements.
The Sierra AT4 has a unique look driven by distinctive 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 Sierra’s bold, C-shaped LED lighting signature.
Additional accent details such as the LED fog lamp bezels and fender badge continue the use of black chrome, while a premium yet distinctly modern high gloss black finish is applied to the window trim, and mirror caps. Touches of red complete the package and make the AT4 stand out with subtle detailing found in the Sierra's all-new AT4 signature emblems and bold, unique vertical tow hooks. All the exterior details create a distinct and modern personality for the AT4 that projects GMC confidence and capability.
A similar appearance continues within Sierra AT4's interior. Sierra AT4 sports unique darkened trim and decor, including dark-tinted and textured real aluminum finishes on the steering wheel, center stack and sill plates, along with unique Jet Black/Kalahari accents and live stitching. Leather-appointed seating ‐ with embroidered AT4 badging on the headrests ‐ and rubber floor liners are standard, which supports the AT4's mission of delivering capability with uncompromising durability and comfort to customers with active lifestyles.
Likewise, Sierra AT4's interior is equally purposeful. For instance, the rear seat backs can open to reveal a pair of 10-liter rectangular storage spaces, which are large enough to store tablets, tie-down cords, or other personal accessories. Additionally, a large 24-liter storage tray underneath the second-row seat offers space to secure other belongings while on the go.
Wheels play a significant part in Sierra AT4's appearance and prominent stance. Unique 18-inch wheels, which boast a finish that matches the truck’s dark chrome elements, are standard. For added off-road traction, all-terrain tires are standard, while mud terrain-rated Goodyear Wrangler Duratrac tires are available. For a more distinctive look, AT4-specific 20-inch machined-face wheels with all-terrain tires are optional.
