For those whose active lifestyles carry them beyond the pavement’s edge, Sierra AT4 provides smart capability, innovative technologies, and off-road capability without compromise. If you’re looking for a full-size pickup whose athletic attitude and appearance match its aptitude and ability - and can confidently travel off-road without sacrificing the refinement and technologies of a GMC - look no further than the 2019 GMC Sierra AT4. Marking the introduction of GMC’s new AT4 model line, the Sierra AT4 is purpose-built to deliver distinctive style, advanced technologies, and off-road capability, making it a premium-grade full-size pickup that’s perfectly at home on the open road or off the beaten path. 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 an 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.
