This is the new 2017 6.6 Duramax diesel engine.

This is not an engine, this is a work of art.

GM produced the redesigned Duramax 6.6L V-8 turbo-diesel, that was offered in the 2017 Silverado HD and the Sierra HD. This next design offers more horsepower and also more torque, coming with 445 horsepower and 910 lb-ft of torque. So all in all this will be a better version of the Duramax, which will enable easier and more confident hauling, and also better trailering.
