Redesigned for 2011, the Silverado heavy-duty lineup is broader than ever, with 10 2500HD models and eight single- and dual-rear-wheel 3500HD models. In the Chevrolet display at the SEMA show, a new, accessorized 2500HD Extended Cab Z71 equipped with the new 6.6L Duramax turbo-diesel engine Allison 1000 six-speed automatic transmission demonstrated the personalization possibilities of the new HD lineup.

New 6.6L Duramax diesel delivers up to 11-percent greater highway fuel economy and up to 63-percent lower emissions, along with B20 biodiesel capability and quicker acceleration
All-new smart exhaust brake feature provides greater control on grades and reduced brake pad wear
An array of control features, including trailer sway control, integrated trailer brake control, hill start assist, automatic grade braking, intelligent brake assist and larger brakes
Purposeful technology, including available mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio, OnStar 9.0 and navigation.
Outside, the 2011 Silverado 2500HD and 3500HD models are distinguished by a power dome-style hood with a new, louvered design, as well as a new grille and full-width chrome steel front bumper. A new lineup of 17-, 18- and 20-inch wheel/tire combinations is featured, too, and the 2500HD SEMA show vehicle displays 20-inch wheels that are available through Chevrolet dealers, but painted Corvette Competition Gray for the show vehicle.
