Chevrolet Silverado, GMC Sierra HD Pickups Ready to Haul

DETROIT--Jan. 28, 2015: Defining the all-new 2015 Chevrolet Silverado and GMC Sierra heavy-duty pickups comes down to four words: Strong, smart, capable and comfortable.

The 2015 Silverado HDs are the heavy lifters in Chevrolet’s three-truck strategy, which includes the all-new 2014 Silverado 1500 and, later this year, the 2015 Colorado midsize truck.

The Sierra 2500HD and 3500HD models – including Sierra Denali HD – feature bold, new styling and all-new, better-connected interiors. A Duramax 6.6L turbo-diesel engine with Allison 1000 six-speed transmission powertrain combination complements powertrain offerings.
