The GMC Sierra Denali 1500 (half-ton) is all-new for the 2019 model year, delivering a completely overhauled (redesigned and re-engineered) truck, with bold design and segment-leading technologies, while advancing Denali’s legacy as the pinnacle of GMC design, capability and refinement.

“GMC ignited the premium truck segment 17 years ago with the original launch of the Sierra Denali,” said Duncan Aldred, vice president of Global GMC. “The next generation 2019 Sierra Denali establishes a new benchmark in capability and refinement. It exemplifies precision in every detail.”

Powerful proportions and distinctive Denali design help define the Sierra’s unmistakable exterior, while the driver-focused cabin strengthens the brand’s reputation for refinement with premium materials, improved interior space and innovative storage solutions.
