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.
All 2011 Silverado HD models bring greater
capability, improved ride and handling and a greater feeling of driver control.
Highlights include:
- Increased towing capability of up to 21,700 pounds (9,843 kg) and
payload of up to 6,635 pounds (3,009 kg) on 3500HD models, supported by
all-new fully-boxed, high-strength-steel frames and strong suspensions.
- 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.
