Just like its predecessor, the Sierra Denali sits at the top of the GMC Sierra lineup, itself a more upscale version of the Chevrolet Silverado 1500. The fourth-generation pickup truck broke cover in March 2018, a few months after Chevrolet debuted the new-generation Silverado it is based on.
At the forefront of the premium pickup market since 1999, the GMC Sierra Denali steps into a new generation with redesigned everything. Larger and bolder, the truck benefits from new state-of-the-art technology, and a new transmission. It also boasts many industry-first features, including a carbon-fiber box, a multi-function tailgate, and a rear-view camera. Power continues to come from the familiar 5.3- and 6.2-liter V-8s, despite the fact that GMC just introduced a diesel V-6 option for the regular Sierra.
