Sierra highlights

The Sierra features an elevated exterior design and all-new, expressive interiors with enhanced technology integration, including a large, 13.4-inch-diagonal touchscreen with Google built-in2 compatibility.

Additionally:

The refreshed exterior features a new grille, revised headlamp design, and expressive lighting animation when approaching, starting, or
walking away from the vehicle.

A new, unique interior design includes a cockpit-oriented instrument panel and a new, more functional center console that features electronic precision shift on models with front bucket seats.

The new, larger 13.4-inch-diagonal color touchscreen is
complemented with a new 12.3-inch-diagonal configurable digital
instrument cluster and 15-inch-diagonal multicolor Head-Up Display
to provide more than 40 diagonal inches of digital display, the most
in its class.
Previously announced for the GMC HUMMER EV Pickup and
introduced on the Yukon, Sierra comes with Google built-in.
Sierra Denali Ultimate trim offers exclusive design and premium
materials, including trailering-capable Super Cruise1 driver-assistance
technology and a standard 420-horsepower, 6.2L V-8 engine.
All-new AT4X trim offers an exclusive premium interior and advanced
off-road capability, with features such as Multimatic DSSV dampers,
front and rear e-lockers, and Terrain Mode with one-pedal crawling,
while delivering excellent on-road comfort and trailering capacity.
A new 2.7L Turbo High-Output engine offers greater refinement,
performance, and enhanced trailering capability.

First-ever Sierra Denali Ultimate trim

Unique exterior styling cues and exclusive interior trim and features are complemented with more standard equipment — including

first-in-class available trailering-capable Super Cruise and the segment-exclusive CarbonPro composite cargo box offering best-in-class

short-bed cargo volume — to set a new standard for premium truck buyers who want to reward themselves.

The Denali Ultimate is distinguished by an exterior featuring a unique grille in exclusive Vader chrome, along with complete 22-inch

wheels finished in Low Gloss Black with machined accents, Vader chrome GMC logo, and unique front fender trim featuring Mount

Denali. Additionally, GMC’s six-way MultiPro tailgate, the Denali Premium Suspension with segment-exclusive Adaptive Ride Control, and power assist steps are standard.

The Denali Ultimate’s Alpine Umber interior builds on the luxurious Denali cabin, with full-grain leather appointments and open-pore

Paldao wood trim. The wood’s darkened finish creates a distinctive color blend, while the unique graining adds bespoke attention to detail.  Regarding propulsion, the Sierra Denali Ultimate’s standard engine is GMC’s 420-hp, 6.2L V-8 and is matched with a 10-speed automatic

transmission featuring Electronic Precision Shift. Four-wheel drive, with an electronically controlled two-speed transfer case, is standard.  The enhanced version of Super Cruise1 hands-free driver-assistance technology and more

Super Cruise is standard on Sierra Denali Ultimate with a three-year subscription to enable the functionality and is available on Sierra

Denali. It is the industry’s first true hands-free driver-assistance technology for compatible roads, and it can be used on more than 200,000 miles (320,000 km) of compatible roads in the U.S. and Canada.

Sierra AT4X: the new peak in premium off-roading

The all-new Sierra AT4X continues GMC’s efforts to break ground in the premium truck category. The Sierra AT4X is a balanced execution that delivers advanced off-road capability when called upon without compromising the on-road comfort, tech, towing, and payload

capability expected from a premium pickup.


Highlights include:

The functional features complement a unique, luxury-focused AT4X Obsidian Rush interior that balances the off-roader’s capability with comfort and convenience. The cabin is awash with premium leather, including full-grain leather-wrapped and technical-grain leather accents, all highlighted with white piping and red stitching.

In addition to the distinctive design cues of the Sierra Denali Ultimate and Sierra AT4X, the vast majority of the Sierra lineup is elevated with styling and design updates, inside and out.

Exterior highlights include:
Revised front bumper, fascia, grille designs, and finishes on each trim
New dual-projector LED headlamps and a revised execution of GMC’s signature C-shaped daytime running lamps give the Sierra a
bolder, wider appearance.
Animated lighting sequences that activate when approaching, starting, or walking away from the truck
New wheel designs on SLT and Denali
Three new exterior colors (extra cost): Titanium Rush Metallic, Dynamic Blue Metallic, and Desert Sand Metallic
What hasn’t changed with Sierra’s exterior are the professional-grade features that underpin its capability, including the available,
industry-first six-function MultiPro tailgate, the available CarbonPro carbon fiber composite bed, which provides more short-bed cargo
bed volume — 63.9 cubic feet — than any other competitor.
Inside, GMC designers set Sierra apart from the competition with unique, new interiors on SLE, Elevation, and SLT trims and unique
premium interior designs for AT4, AT4X, Denali, and Denali Ultimate trims. There are also new color and stitching designs, with more
premium materials throughout the cabin, further elevating Sierra’s premium look and feel.
Additional interior highlights include:
All-new 13.4-inch-diagonal horizontal infotainment10 touchscreen (standard on SLE trim and above)
The all-new 12.3-inch-diagonal digital, configurable instrument cluster (standard on SLE trim and above)
A new center console design
All-new Electronic Precision Shift on models with front bucket seats (a column shifter is available on models equipped with a front bench
seat)
New, available Elevation Premium Package that includes a Jet Black leather-appointed interior with bucket seats, rear seat with storage,
Sierra Safety Plus Package5, spray-on bedliner, and more
A new power-adjustable steering column is standard on up-level trims.
New 13.4-inch-diagonal screen, Google built-in2 and more
The centerpiece of the Sierra’s redesigned interior (SLE trim and above) is an all-new and customizable 13.4-inch-diagonal horizontal
touchscreen, along with a 12.3-inch-diagonal digital, configurable instrument cluster. Together, they provide users with incredible levels
of personalization and intuitive engagement, starting when the driver slides behind the wheel and the driver information center come to life.
