GMC's Sierra 1500 will add a carbon fiber bed, 3.0L Duramax turbo-diesel, 10-speed automatic transmission, and other technology for the 2020 pickup, GMC has announced.
Adding to Sierra’s current suite of towing tech, 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, according to GMC.
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.
The previously announced available 3.0L Duramax inline-six turbo-diesel engine will pair with the 10-speed automatic as well. The 3.0L Duramax produces an SAE-certified 277 hp and 460 lb.-ft. of torque.
For 2020, the 3.0L Duramax is now available in conjunction with the CarbonPro Edition of the Denali and AT4 models, pairing the innovative turbo-diesel engine with the industry’s first carbon fiber bed for the first time.
Beyond the CarbonPro Edition, the 3.0L Duramax is also available on Denali, AT4, SLT, Elevation and SLE models.

The ProGrade Trailering System now features a 15 available unique camera views, including a transparent trailer view to help optimize the driver’s view around the truck and compatible trailers.

The ProGrade Trailering System now features a 15 available unique camera views, including a transparent trailer view to help optimize the driver’s view around the truck and compatible trailers. 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 in-vehicle Trailering App has updated features and enhanced mobile integration for 2020. 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 Electronics through the myGMC mobile app, 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, drivers 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.
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.
