2011 Chevrolet Silverado HD Revealed

Chevrolet presented the 2011 Silverado HD at the Chicago Auto Show, a model that comes with several enhancements for model year 2011. Feature highlights for the new model include the 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.

“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.

“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.”

There are two powertrains available across the range, as follows: a 6.6-liter Duramax diesel configuration that is mated to an Allison 1000 six-speed automatic transmission plus a Vortec 6.0-liter with Hydramatic six-speed automatic gearbox.

“It takes some courage to leave your foot off the brake, but the Silverado’s Duramax engine and Allison transmission perform the task with smoothness and confidence that really impresses,” said engineer Brent Deep. “Better still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on long descents.”
