ENGINEERING EXPLAINED: GMC SIERRA 1500 DENALI

In order to take a closer look at the details that truly make the GMC Sierra Denali a true Denali, we asked brand ambassador Jason Fenske, the engineer behind “Engineering Explained,” to walk through the features that allow Sierra Denali to provide a unique blend of premium appointments and smart capability.

Bold looks. Refined interior. Strong capability. Premium performance. These are the attributes that have not only made the GMC Sierra Denali an icon in its class, but also help distinguish the GMC Sierra Denali 1500 from other full-size 1500 pickups on the market.

EXTERIOR

Sierra Denali stands out from the crowd thanks to bold styling, accentuated with precisely-crafted details that are both stylish and functional. Case in point? Sierra Denali includes headlamps that not only utilize LED lighting to deliver GMC’s C-shaped signature lighting, but also utilizes LEDs for both high and low-beam headlamps. A standard spray-on bedliner, capped with a bold three-dimensional “DENALI” emblem at the front of the box, protects bed surfaces from cargo and debris while delivering added grip. And a standard CornerStep rear bumper, along with a remote-locking EZ-Lift-and-Lower tailgate, ease getting in and out of the pickup box.

INTERIOR

Sierra Denali has an interior that is as impressive as its powertrain and capability. Premium materials, like real, burnished-aluminum trim, soft-touch dash trim with contrasting accent stitching, perforated leather-appointed seating, and other unique touches easily set Denali apart from other trucks. Those upscale appointments are paired with advanced technology, including a configurable 8-in. diagonal Driver Information Centre within the gauge cluster, and an 8-in. diagonal colour touch-screen with the GMC IntelliLink®1 and Navigation2, Bluetooth®3, and Android™ Auto and Apple CarPlay™ compatibility4.

QUIET CABIN

Even before adding the premium materials, GMC engineers worked to ensure Sierra Denali’s cab could be as refined as possible. In a calculated effort to help minimize road and wind noise, GMC engineers carefully shaped the cab and mirrors to be as aerodynamically efficient as possible. Inlaid doors, along with triple-layer door seals, further help keep wind noise from intruding into the cabin. Select Sierra Denali models are also available with an Active Noise Cancellation system, which utilizes the audio system to further help block unwanted noises under certain conditions.

ENGINE

A robust powertrain plays a big role in providing great performance, and Sierra Denali’s available 6.2-litre V8 is no slouch, thanks to 420 horsepower and 460 lb.-ft. of torque. Advanced technologies, such as Direct Injection, continual variable valve timing, and Active Fuel Management® technology all contribute to not only maximizing efficiency, but delivering peak power when needed most.

TRI-MODE POWER STEPS

Available on Sierra Denali and standard on the Sierra Denali Ultimate, these innovative powered steps provide elegant and effortless access to both cab and cargo alike. Open any of the cab doors, and the steps quickly fold down for use. Tap a shoe on the rear edge of the step board, and the entire assembly pivots rearward, allowing you to step up and reach items within the cargo box.
