GMC is taking its most popular pickup truck to the next level with the completely redesigned 2019 Sierra Denali and SLT.

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.

GMC exclusive, industry-first carbon fiber pickup box, the CarbonPro, was developed to increase durability, efficiency and functionality while offering best-in-class dent, scratch and corrosion resistance.

The 2019 Sierra Denali debuts a profound new GMC design. A taller, more confident stance gives Sierra Denali powerful proportions complemented by hallmark details such as a chrome grille with a sharp, precise dimensional pattern that epitomizes the truck's attention to detail.

Sierra shows refinement and strength through a larger, more-dominant upright grille, a taller hood, and a bolder, more pronounced take on GMC's C-shaped lighting signature.

The truck is larger than the previous truck in virtually every dimension, and the larger grille and dramatic lighting accentuate its broad-shouldered stance. The wheels are pushed closer to the corners and wear larger diameter tires.

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 new diesel builds on GMC's expertise with Duramax turbo-diesels offered in Sierra HD and Canyon models. The available 6.2L and 3.0L engines are paired with a 10-speed automatic transmission.

Sierra Denali features an exclusive Adaptive Ride Control suspension system designed to provide premium driving refinement with exceptional responsiveness.
