GMC Sierra 2500HD Model Years

, Automotive Editor -

The mid-level hauler in the GMC's full-size pickup family, the Sierra 2500HD (shorthand for Heavy Duty) can be equipped like a bare-bones laborer, a luxury yacht and everything in-between. Beneath the skin, however, all 2500HDs are equal: industrial-strength frame, abundant power, beefy transmission and towing capacity up to 17,800 pounds. That's some serious grunt—even in the world of full-size pickups—and only a select few models can handle more.

Although the current Sierra debuted in 2007, GMC trucks have populated farms and construction sites for generations. Perhaps in a nod to its customers' professions, the 2013 model can now run on natural gas in addition to gasoline.

Major changes included:

In 2007, GMC released the second-gen 2500HD with a fully restyled body that helps distinguish it from its sibling, the Chevy Silverado, and an upgraded interior with a more premium appearance. The second generation also brought about revisions to the powerplants, with the base 6-liter being tweaked to 353 horsepower and 373 pound-feet of torque, and the 6.6-liter diesel hitting 365 horses and 660 pound-feet. GMC again revised the 6-liter V8 in 2010, boosting it to 360 horsepower and 380 pound-feet of torque. 2011 brought in a brand-new suspension system and a new-generation 6.6-liter diesel with 397 horsepower and 765 pound-feet of torque.

Major changes included:

In 2001, the 2500HD debuts as its own model after serving as a trim level between 1994 and 2000. It arrived with a base 6-liter V8 with 300 horsepower and 360 pound-feet of torque, but had two optional engines: a 6.6-liter V8 diesel with 300 horsepower and 520 pound-feet of torque, and an 8.1-liter V8 with 340 horses and 455 pound-feet of torque. In 2003, GMC modified the 6-liter V8 to accept compressed natural gas in place of gasoline and gave the 2500HD a revised front fascia. In 2006, GMC tweaked the diesel engine for reduced emissions and upped its output to 360 horsepower and 650 pound-feet of torque.
