The automaker released photos and some information about the Silverado HD Tuesday before its official debut in February.
The redesigned Silverado HD will be offered with a new gasoline engine with direct injection mated to a six-speed transmission, or the Duramax turbodiesel V-8, rated at 910 pound-feet of torque, with a new Allison 10-speed transmission.
The company said the Silverado HD will have "all-new customer-focused trailering technology" and "significant increases in towing and payload capabilities," but it did not release performance metrics.
The 2020 Silverado HD -- produced in Flint, Mich. -- is expected to go on sale in mid-2019. It will be the third new or redesigned Silverado in the last 18 months, following the redesigned 1500 and new medium-duty.
