2020 Chevy Silverado 3500 6.6-liter Duramax diesel


With best-in-class 35,500 pounds towing capability, Chevy’s 1-ton workhorse proved impressive at the company’s ride-n-drive event in Bend, Oregon. Sandor Piszar, Chevy truck marketing director, talks about the truck’s fleet appeal and Chevy lead development engineer Chris DePolo explains how a new Allison 10-speed transmission enabled an improved axle ratio of 3.42 (down from 3.73) and thus better fuel economy.
