For those looking to take
refined capability off-road, GMC fortifies the new AT4 brand with an all-new
Sierra AT4 Heavy Duty available for Crew Cab configurations as both a 2500 and
3500 single rear wheel offering.
With more than half of Sierra HD customers choosing
Denali, it continues to offer the ultimate expression of professional grade
materials and refinement. The all-new model delivers power, intelligence and
segment advancements to meet the needs of heavy-duty customers with discerning
taste.
ProGrade Trailering
Technology
First introduced with the 2019 Sierra light duty,
the ProGrade Trailering System leverages technology advancements to offer
additional features and functionality for the 2020 Sierra Heavy Duty.
“Trailering is the most important consideration for Sierra Heavy Duty
customers, and the new features and technologies in the 2020 Sierra HD make it
easier than ever to hitch a trailer and tow it confidently,” said Jaclyn
McQuaid, vehicle chief engineer, Heavy Duty Trucks. “We’ve developed this new
truck to offer the greatest trailering experience ever offered by GMC.”
An available class-leading 15 unique camera views1, including an industry-first transparent trailer
view, help optimize the driver’s view around the truck and compatible trailers
to provide added confidence when towing. The revolutionary transparent trailer feature
uses the tailgate-mounted camera and an available accessory camera mounted on
the rear of the trailer. The resulting display helps the driver to virtually
see through the trailer4, a
benefit when navigating parking lots, merging into traffic or making tight
turns.
Owners of the 2020 Sierra HD will have access to available
smart trailer technology designed to allow access to
select features of the iN∙Command® control system from ASA Electronics2 through the myGMC mobile app, either on compatible
Android and iOS smartphones or on the vehicle’s infotainment system via Apple
CarPlay5 or
Android Auto6. Similar to the features of a smart home, the iN∙Command®
control system acts as the central hub of operations to monitor and control an
array of systems in trailers equipped with the next-generation technology.
Depending on how a compatibly equipped trailer is configured, owners of the
2020 Sierra HD may be able to turn on the trailer’s air conditioning or water
heater, check water and holding tank levels, or monitor fuel levels on trailers
equipped with generators — all before arriving at their destination.
The ProGrade Trailering System also includes an in-vehicle
Trailering App7
with Trailer Light Test, Trailer Electrical Diagnostics, Trailer Tire Pressure
and Temperature Monitoring, Pre- Maintenance Reminders and Departure Checklist.
Many of the Trailering app’s functions, including the lighting test and
pre-departure checklist, are also available with the myGMC mobile app, a
feature that offers great convenience when outside the truck or trailer.
Additional available technologies and hardware to aid trailering
include:
- Auto Electric Park Brake to automatically apply the parking brake to help maintain truck position when hitching.
- All-new Park Grade Hold Assist enhances hill hold by using braking effort at each wheel for an extended period of time.
- All-new larger, door-mounted trailering mirrors with a four-bar link providing power extend and retract for the driver and passenger sides.
- Integrated trailer brake controller that works with the trailer profile in the Trailering App to recall a specified trailer’s most recent gain setting.
- Tow/Haul mode that remains engaged on the next key-on cycle, for up to four hours; includes a reminder the feature is engaged.
- Hill Start Assist and Hill Descent Control.
- Trailer Sway Control.
- Auto Grade Braking and Diesel Exhaust Braking.
- Digital Variable Steering Assist that dynamically optimizes power steering according to driving scenarios, including trailering, and enables features like road pull compensation.
- Trailering Info Label placed on the driver’s door jamb that clearly calls out the truck’s specific trailering information, including curb weight, GVWR, GCWR, maximum payload, maximum tongue weight and rear GAWR.8
Bigger and bolder
The 2020 Sierra HD has a commanding, powerful design
rooted in a new architecture with larger proportions. It is taller and longer,
with a more confident stance defined by a bold design that epitomizes GMC’s
signature refinement and technologically driven attention to detail.
“We took every opportunity to visually express the
strength and capability that lies beneath the surface,” says Matt Noone,
director of GMC exterior design. “The elevated hood line, the strong shoulders,
the striking front grille — these cues communicate the strength and performance
that have been engineered and built into each and every Sierra Heavy Duty.”
The all-new Sierra HD is highlighted by new
signature lighting, including prominent “light blades” that deliver LED
illumination for the daytime running lamps. LEDs are also used for the
headlamps, taillamps, available fog lamps and other illuminative elements,
including the available roof marker lights standard on all dual-rear-wheel HDs
and all Sierra HD Denalis except where prohibited by law.
Inside, the Sierra HD’s new interior has
best-in-class front head- and legroom (maximum), with Crew Cab models. A higher
seating position complements the truck’s taller profile to offer a confident
view from behind the wheel. Additional optimized ergonomics emphasize easy,
intuitive interaction with the vehicle’s available technologies, such as a
heavy-duty segment-first head-up display and GMC’s latest touchscreen
infotainment systems.9
Denali-exclusive materials — including premium
leather-appointed seating, authentic open-pore wood trim and dark-finish
aluminum decor — raise the interior’s refinement. The leather appointments have
a distinctive, large-pebbled grain with a contrasting stitch pattern that is
premium in appearance and touch without sacrificing durability, and the wood
trim features an open-pore texture evocative of hand-planed
furniture.
Compared to the current model, the new Sierra Heavy
Duty has:
- A longer wheelbase, a taller, more dominant hood line and taller overall height.
- A larger grille and complementing functional hood scoop to feed an advanced cooling system for the Duramax turbo diesel.
- Class-leading heavy-duty cargo bed volume10 and 12 corner tie-downs with a new, available 120-volt power outlet.
- One-inch-lower bed lift-in height compared to the 2019 Sierra Heavy Duty, providing easier loading and fifth-wheel and gooseneck trailer hitching10.
- New, segment-exclusive cargo bed side steps on all box styles, located in front of the rear wheel openings, that complement integrated CornerSteps in the rear bumper to improve access to the cargo area.
- World’s first six-function MultiPro tailgate available on all trim levels and standard on SLT, AT4 and Denali.
All-new Sierra AT4 HD: Refined HD
Capability Off-Road
The all-new 2020 Sierra Heavy Duty AT4 continues the AT4 brand’s
growth with a distinctive off-road identity to complement its robust HD
capability. Driven by dark chrome exterior finishes and contemporary detailing,
Sierra HD AT4 features front and rear bumpers and a grille surround finished in
body color. The bold grille design, with its rugged texture, is finished in
black chrome and set off by the AT4’s distinctive red vertical recovery hooks.
The
athletic interior also carries AT4-specific darkened trim, including
dark-tinted and textured aluminum finishes on the steering
wheel, center stack and sill plates, as well as a unique Jet Black
interior with Kalahari color accents in the seats and live stitching.
Leather-appointed seating, with mini-perforated inserts and embroidered
AT4 badging on the headrests, along with all-weather floor liners, is standard
delivering durability with uncompromising comfort.
The new Sierra AT4 Heavy Duty’s off-road capabilities are rooted in a
unique suspension and supporting technologies that include:
- Off-road suspension, Rancho Shocks, skid plates, Eaton locking rear differential.
- Eighteen-inch wheels wrapped with Michelin all-terrain tires, with 20-inch wheels available.
- Traction Select System with specific Off-Road mode.
- Hill Descent Control and Hill Start Assist.
- Segment-exclusive 15-inch diagonal Head-Up Display with Off-Road Inclinometer.
- HD Surround Vision1 for low-speed views of vehicle surroundings.
Confident trailering power
GMC’s legendary Duramax turbo diesel and Allison
Transmission pairing continues to offer the ultimate in towing confidence.
The proven Duramax 6.6L turbo-diesel engine offers
high torque, high power, low noise and exceptional durability. For the 2020
Sierra HD, the Duramax offers an SAE-certified 445 horsepower and 910 lb-ft of
torque. This already powerful engine performs more efficiently thanks to
increased cooling capacity delivered in part by improved air induction. A
dual-path intake system draws dense, cool air through both the prominent hood
scoop and the larger front grille.
The new Sierra HD marks the introduction of an
all-new 10-speed Allison automatic transmission — the first-ever offered in the
heavy-duty pickup segment. The all-new 10-speed transmission with closer gear
spacing allows the engine to operate in an optimal range at all times with
varying load and terrain conditions.
The bigger frame, stronger propulsion and smarter
technologies are expected to deliver dramatically greater towing capacity than
previous models, well in excess of 30,000 pounds. More details regarding an
all-new gas engine and trailering capabilities will be announced shortly.
Coming late summer 2019
The 2020 Sierra HD goes on sale later this year in
2500HD and 3500HD dual rear wheel and single rear wheel configurations. Pricing
and complete specifications will be announced later.
With a $1.5 billion investment to support the
next-generation Heavy Duty truck launch, Flint Assembly in Flint, Michigan,
will proudly build the 2020 Sierra Heavy Duty.
