The 2019 Chevrolet Silverado has made its official debut, dropping 450 lbs over the outgoing model and adding a diesel engine option.

Available engines for the all-new Silverado include heavily updated versions of the 5.3-liter and 6.2-liter Small Block, along with an all-new 3.0-liter inline-six Duramax diesel engine. General Motorsdidn’t share details on the diesel’s power output, but head of GM product development, Mark Reuss, assured us it would be more powerful than Ford’s new diesel in the F-150. The diesel and the 6.2 will be available with GM’s new Hydramatic 10-speed automatic transmission, while the 5.3 will come with the eight-speed.
