GMC is taking its most popular pickup truck to the next level with the completely redesigned 2019 Sierra Denali and SLT. Distinguished by bold design and segment-leading technologies, the next generation Sierra Denali once again redefines the premium pickup, 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."

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.

Advanced lighting technology distinguishes the Sierra Denali from every other truck on the road. GMC’s front lighting signature is conveyed through a prominent "light blade" that delivers uniform LED illumination for the daytime running lamps. LEDs are also used for the headlamps, taillamps, fog lamps and other illuminative elements, with lenses constructed from durable material with an almost crystalline quality.

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. Denali features available 22-inch Ultra Bright aluminum wheels; the SLT model offers its own unique 22-inch dark aluminum wheels finished with chrome accents.

Proven V8-engines joined by an all new Turbodiesel

New versions of the proven 6.2L and 5.3L V-8 engines will be joined by an all-new 3.0L inline-six turbo-diesel engine, expanding the powertrain lineup for the 2019 Sierra. 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. It employs sophisticated sensors to monitor road conditions and chassis responses in real time, enabling adjustments to active dampers every 2 milliseconds.

An elevated interior refined for the 2019 edition

Putting the driver at the center of experience starts with a higher seating position that offers a confident view behind the wheel. The optimized ergonomics emphasize easy, intuitive interaction with the vehicle’s technologies, such as the all-new Trailering App and segment-first Head-Up Display.

Denali-exclusive materials — including premium leather-appointed seating, authentic open-pore wood trim and dark-finish aluminum decor — help raise the interior to a new level of refinement. The exclusive leather appointments have a distinctive, large-pebbled grain with a contrasting stitch pattern that is both premium in appearance and touch without sacrificing durability, and the wood trim features an open-pore texture evocative of hand-planed furniture.

When it comes to the space and storage vital to truck customers, the 2019 Sierra’s crew cab has nearly 3 inches of additional rear-seat legroom compared to the current model. The outboard rear seat backs open to reveal rectangular storage spaces large enough for storing tablets or laptops, tie-down cords, umbrellas or other important accessories.

Groundbreaking cargo box capability and materials

The cargo boxes also offer best-in-class cargo volume - 63 cubic feet (1,784 litres) on the short box, as well as additional tie-downs and a new, available 110-volt power outlet. The bed continues to be made of roll-formed, high-strength steel, yet a revised alloy offers 50 percent more strength than the current model.

The 2019 Sierra Denali will offer, later in the model year, an available GMC exclusive and industry-first carbon fiber box — the CarbonPro — developed to increase durability, efficiency and functionality of the truck. It replaces the standard steel inner panels and floor with a lightweight, purpose-designed carbon fiber composite that offers best-in-class dent, scratch and corrosion resistance, making it the most durable pickup box in the segment.

ProGrade Trailering System with Trailering App

The 2019 Sierra offers a more confident towing experience thanks to GMC’s new ProGrade Trailering System, standard on Denali and SLT. The trailering system includes an all-new Trailering App featuring a Pre-Departure checklist, Maintenance Reminders, Trailer Light Test, Trailer Electrical Diagnostics and Trailer Tire Pressure and Temperature Monitoring.

Many of the Trailering App’s functions, including the lighting test and pre-departure checklist, are also available with the MyGMC app on compatible Android and iOS smartphones, a feature that offers great convenience when outside the truck or trailer.

The next generation Sierra also offers Hitch Guidance with Hitch View and Auto Electric Park Brake to help with perfect positioning when hitching. The available side view cameras and a trailer-mounted HD camera provide additional assistance when driving down the road or in reverse. With exclusive Trailer Theft Detection, owners can receive text and mobile alerts from OnStar when the trailer has been detached from the truck without permission.
