Chevrolet has unwrapped the Silverado HD line-up for model year 2011 at the Chicago Auto Show. Boasting the best-in-class payload capability, the new Silverado heavy-duty truck is available in 11 different 2500HD model variations and 8 single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box.

"We reached out to our customers during the development of the 2011 Silverado HD and considered their input to produce a truck that offers class-leading strength and capability with more power, quicker acceleration and lower emissions," said Jim Campbell, Chevrolet general manager.

The new Chevrolet Silverado HD boasts some serious refinements for 2011: all-new, fully-boxed frame assemblies, stronger independent and new asymmetrical leaf-spring rear suspensions, a strengthened 6.0L Vortec 6L90 standard power unit; a new, exclusive exhaust brake system, larger brakes, improved handling and steering, 170-degree-opening rear access doors on extended cab models and state-of-the art connectivity.

Depending on the variation, the new Silverado HD offers:

  • On the available Duramax 6.6L diesel, horsepower and torque are expected to top the previous model, along with expected segment-best fuel economy and B20 biodiesel capability
  • Segment-best fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
  • Segment-best conventional towing capacity increases up to 23 percent, with a  maximum of 16,000 pounds (7,272 kg)
  • Segment-best payload capability of 6,335 pounds (2,873 kg) with a complete vehicle
  • Segment-best Gross Combined Weight Rating increases to 27,500 pounds (12,500 kg)
  • Gross Vehicle Weight Ratings increases up to 17 percent to 13,000 pounds (5,909 kg)
  • Front Axle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
  • Exhaust brake system designed to extend brake pad life and help avoid overheating on long descents
  • Snow plow capability enabled for all 4WD cab configurations

"Along with all their heavy-duty equipment, these trucks are designed to be stylish and refined, inside and out," said Campbell. "We paid close attention to all the details, giving them a distinctive, muscular appearance on the exterior and a well-appointed interior with the comfort, convenience and safety features customers appreciate."

In the terms of styling, the new Silverado 2500HD and 3500HD models pack more solid and vigor body than ever. At the first glance, the front end bentits from new power dome-style hood with a new, louvered design, as well as a new grille and full-width chrome steel front bumper. A new wheel design is available in 17-, 18- and 20-inches.
