Fresh off the release of the 2020 Silverado, Chevrolet is introducing the HD version of its popular truck at the Chicago Auto Show, and the number one word is towing. The max towing load is now 35,500 pounds when properly equipped, a massive 52% jump from the outgoing model. Payload also received a significant increase to 7,466 pounds. Both ratings owe their increases to the new 6.6-liter Duramax turbo-diesel V8. With 455 horsepower, 910 lb-ft of torque, and features like a warning to keep the engine running to cool if it's hot — and if the driver ignores it, the remote start will crank the engine and override the operator. The Duramax diesel is paired with a new Allison 10-speed transmission, while standard HD models get a 6.6-liter gasoline V8 with 401 horsepower and 464 lb-ft of torque. Aids like Park Grade Hold Assist work the brakes when stopped on hills, and up to 15 different rear camera angles eliminate the need for a buddy to help you line up the trailer. The 2020 Silverado arrives at dealers this summer, with pricing available leading up to the release date.
