The 2013 product information for the Chevrolet Silverado HD and Sierra HD pickup trucks was released Tuesday, and as you might expect, there isn't much change from 2012.
The 2013 order book includes a new CNG bifuel option package on Silverado 2500 HD and Sierra 2500 HD extended cabs. The trucks can be ordered at any dealership in four- or two-wheel-drive configurations, with an 8-foot long bed or 6-foot-7-inch short bed.
The 2013 HD models will be offered with two new colors: Deep Ruby Metallic and Blue Topaz Metallic for the Silverado 2500 and 3500 HD. The GMC models will get a new Sonoma Red Metallic and Heritage Blue Metallic.
The one final improvement that will be included on all GM HD trucks (Chevy and GMC) is that the six-speed transmission available with the 6.0-liter V-8 gas option will include the same grade-braking capability in normal driving mode that it had previously only when tow/haul mode was selected.
