An available class-leading 15 unique camera views, 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 trailer, a benefit when navigating parking lots, merging into traffic or making tight turns.
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.
