The all-new 2019 GMC Sierra Denali and SLT have been unveiled, featuring an available industry-first truck bed made of carbon fibre and a six-function tailgate.
The new Sierra follows the earlier introduction of its sibling Chevrolet Silverado, which is also an all-new model for 2019.
“GMC ignited the premium truck segment seventeen years ago, with the original launch of the Sierra Denali,” says Duncan Aldred, vice-president of Global GMC. “The next-generation 2019 Sierra Denali establishes a new benchmark in capability and refinement.”
The new Sierra will use new versions of the current 5.3-litre and 6.2-litre V8 engines, both with ten-speed automatic transmissions, along with an all-new 3.0-litre inline six-cylinder turbodiesel. The gasoline engines feature start-stop technology and a new fuel management system that operates on one to eight cylinders, depending on power demand, for improved efficiency.
The company says the carbon-fibre pickup box, dubbed the CarbonPro, was developed to increase durability and functionality, while offering dent, scratch, and corrosion resistance. GMC calls it “the most durable pickup box in the segment.” It will be an option in place of the truck’s standard bed, which is made of roll-formed, high-strength steel.
The CarbonPro box is 28 kilograms lighter than the steel version. The new Sierra also features aluminum doors, hood and tailgate, and even with the standard steel box, is up to 163 kilograms lighter than the current Sierra.
The new MultiPro Tailgate offers six functions and positions, with second-tier loading, standing work station, and easier access to items in the box. The tailgate feature will be standard equipment on the Denali and SLT. The new Sierra also retains the outgoing model’s simple bumper step for easier bed access.
The new truck also includes a connected suite of trailering apps, a multi-colour head-up display, and a dual-function rear camera mirror that can see behind the vehicle even if the view is obstructed by cargo. This next-generation mirror has a higher-resolution camera, and the ability to zoom or tilt for better visibility.
The new Sierra is larger and taller than the previous truck, with a larger upright grille, taller hood, and more refined C-shaped front lighting. Inside, the crew cab has 76 mm more rear legroom than before, and the rear seat backs conceal storage spaces large enough for tablets, laptops, umbrellas, or tie-down cords.
The top-line Denali includes premium leather seats, open-pore wood, dark-finish aluminum trim, and contrasting stitching, among other luxury features.
