The GMC Sierra 2500HD 4WD was first released to the American public in 1990 along with its counterpart, the Chevrolet Silverado. Initially, the two models were almost completely identical; however, over the years, the GMC Sierra 2500 has become more a luxury model to the Silverado's utilitarian version.
Competing with the Ram 2500, the GMC Sierra 2500 4WD was not accompanied by the "Heavy Duty" badging until 2001. With it came an impressive 360 horsepower Duramax V8 engine and a five-speed Allison 1000 automatic transmission. An optional six-speed automatic transmission was not released until the 2006 model year.
The Sierra 2500HD has not seen many exterior changes since its inception. Nevertheless, minor alterations have occurred like a more streamlined profile and chiseled appearance. But, GMC has mainly stayed with the classic Sierra/Silverado exterior since the 1999 model year.
One of the most remarkable attributes of the GMC Sierra 4WD is its superior towing and hauling capabilities. The 2500HD model can handle a payload up to 4,058-lbs, while its towing capacity tops out at 10,600-lbs. This is the primary reason that the HD 4WD versions of the Sierra have been mostly used by those in the construction industry. The model is able to handle loads that most other mass produced pickups could not tolerate.
The Sierra HD has received several awards over the years including Truck of the Year from Motor Trend Magazine in 2001. Though the GMC Sierra will be available in early 2009 as a hybrid model, the demands of a heavy duty truck do not allow hybrid technology to be applied to the 2500HD. However, the regular 2500 will get the hybrid makeover.
The GMC Sierra 2500HD 4WD has been seen on both the silver screen and primetime television. Movies like Sweet Home Alabama, The Dukes of Hazzard, and Final Destination 3 gave the model a role, while T.V. shows like Ghost Whisperer, Jericho, and CSI:NY have utilized the pickup as well.
An attractive feature of the GMC Sierra 2500HD is its ability to be customized. Not only does the maker offer a great number of options, many owners choose to modify the model with lift and body kits. Rumors have been flying that the GMC Sierra will be offered with a lift kit directly from the factory. However, GMC has yet to confirm or deny the claim. Critics say that additions like this would give the Sierra 2500 a younger appeal, something that the model has lacked since the beginning.
