An All-New 6.6L V8 Gas Engine

For 2020, Chevy aimed to take everything they had learned about the previous 6.0L gas engine, and put it into an improved All-New 6.6L V8 gas motor. Which is mated with an upgraded 6-speed automatic transmission. It features industry first direct injection, which increases the compression ratio of this motor to 10.8:1. This allows this gas motor to have 464 lb-ft of torque on regular fuel. Additions increasing the strength of the motor include, gray cast iron materials, forged powder metal rods, forged steel crankshaft, and stainless steel exhaust. Whether you haul big equipment or smaller trailers, this gas motor gets you the best performance on regular fuel.

Compression Ratio 10.8:1
Bore Stroke 103.25 MM X 98.0 MM


ALL-NEW 6.6L V8 Duramax

Available Duramax® 6.6l Turbo-Diesel V8

The 6.6L Duramax Diesel engine has always been the main choice of power for the Heavy Duty Silverado drivers. That’s all for two main reasons, power and dependability.

The 445hp 6.6L Turbo Diesel can now haul heavy loads without breaking a sweat. Pushing out 910 lb.-ft of torque, the 2020 Sivlerado HD’s gooseneck towing capability increases by 52%, bringing it to a segment leading 35,500 lbs with a 3500 Reg Cab Dually. Paired together with the all-new Allison 10-speed transmission, the 2020 Duramax is an extremely smooth driving experience while daily driving and more importantly while towing.
