(May 21, 2019) DETROIT — GMC is taking premium to the next level with expanded availability for its carbon fiber bed, 3.0L Duramax turbo-diesel and 10-speed automatic transmission, plus additional technology like Adaptive Cruise Control – Camera to elevate the ownership experience in the 2020 Sierra 1500. The updates add to a portfolio of technologies that elevate the ownership experience.

“The Sierra is delivering the tech customers want in the light-duty truck market, and the 2020 model demonstrates that Professional Grade means never slowing down,” said Duncan Aldred, vice president of Global GMC.

“In just its first year on the market, the 2019 Sierra introduced the available, industry-first CarbonPro Bed and MultiPro tailgate. The truck’s 2020 updates show how the Sierra continues to raise the bar year in and year out.”

The Sierra 1500’s updates include:

    • Available Enhanced ProGrade Trailering features a segment-first transparent trailer view, originally introduced on the soon-to-launch 2020 Sierra HD, with a segment-leading 15 total available camera views.

    • Available Adaptive Cruise Control – Camera.

    • Elevation model now offered in Crew Cab configuration.

    • First full model-year availability of the 3.0L Duramax turbo-diesel and the CarbonPro Editions with the carbon fiber bed (both late 2019 model year additions).

    • Available 3.0L Duramax turbo-diesel added to CarbonPro Edition propulsion options, previously offered only with 6.2L V-8.

    • 10-speed automatic transmission availability expands to 5.3L V-8 models (SLT, AT4 and Denali models with 4WD).

   •  New trailer tow mirrors are available as a free-flow option.

    • 8-inch-diagonal infotainment system now capable of supporting SiriusXM with 360L (if equipped).

The GMC Sierra already features an innovative suite of towing technologies that enable an exceptional light-duty towing experience. For 2020, the Sierra 1500 will be available with the upgraded ProGrade Trailering System introduced earlier this year on the 2020 Sierra HD. The updated system brings more camera views and in-vehicle Trailering App enhancements designed to simplify and streamline the trailering process.



The ProGrade Trailering System now features an available class-leading 15 unique camera views, including a segment-first transparent trailer view to help optimize the driver’s view around the truck and compatible trailers to provide added confidence when towing. New for 2020, the available transparent trailer view 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, benefiting drivers when navigating parking lots, merging into traffic and making tight turns.

The in-vehicle Trailering App has updated features and enhanced mobile integration for 2020. Owners will now be able to create and edit trailer profiles through the myGMC mobile app and load them into their Sierra, saving time when hooking up for the first time. Owners will also have the option of making a trailer profile shareable for easy transfer of trailer specs. The in-vehicle Trailering App will now also send maintenance reminders and trailer mileage information to an owner’s phone, available for viewing through the myGMC mobile app.

Also new for 2020, the Sierra 1500 will feature available smart trailer technology designed to allow access to select features of the iN∙Command Control System from ASA Electronics5 through the myGMC mobile app6, either on compatible Android and iOS smartphones or on the vehicle’s infotainment system via Apple CarPlay or Android Auto compatibility.

Depending on how a compatibly equipped trailer is configured, owners of the 2020 Sierra 1500 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.

Technology enhancements

For 2020, the Sierra also receives Adaptive Cruise Control – Camera available on SLT, AT4 and Denali trim levels. The system features a single high-mounted camera behind the rearview mirror and can bring the Sierra to a complete stop.

The 2020 Sierra is also capable of supporting SiriusXM’s next generation audio entertainment platform. Available SiriusXM with 360L combines satellite and streaming to deliver more channels and choices than before, giving drivers and their passengers more control over what they listen to and when, and improving listeners’ ability to discover more great content across SiriusXM.

Propulsion system advancements

New for 2020, the 10-speed automatic transmission is now offered with the 5.3L V-8 with Dynamic Fuel Management. The 5.3L V-8 and 10-speed automatic pairing will be standard on the Sierra Denali and Sierra AT4 and available on all four-wheel drive Sierras with the SLE trim level and above. The 10-speed automatic has more gears for more ratios, giving Sierra refined performance and outstanding shift quality.

The previously announced available 3.0L Duramax inline-six turbo-diesel engine will pair with the 10-speed automatic as well, bringing class-leading horsepower and torque figures. The 3.0L Duramax produces an SAE-certified 277 horsepower and 460 lb-ft of torque.
