When the job at hand requires more grunt than a standard 1500 pickup truck can manage, those in the know call on the big guns from GMC, namely the 2014 GMC Sierra HD. Available in both 3/4- and 1-ton configurations, the Sierra HD has the muscle and frame strength to tow, haul and push objects that would leave lesser trucks burning up transmissions and dropping driveshafts. Beyond its numerous cab and axle configurations the Sierra HD also includes the Denali trim that brings a touch of sophistication to this working-class pack mule. Similar trucks from Ram and Ford offer roughly the same features and abilities, as well as resale, leaving the choice of getting a GMC purely up to buyer perception and preference.

If you need to haul big payloads exceeding 10,000 pounds or conventionally tow up to 18,000 pounds, the 2014 GMC Sierra HD has you covered. The Denali trim should hold special appeal for those who use their work truck as a daily driver.

While the Sierra HD is powerful, it's not the king of the hill. The Ram 3500's 30,000-pound max towing capacity is off the charts, and its styling both inside and out is more modern than the Sierra HD.
What's New for 2014
For 2014, the gasoline-powered GMC Sierra gets a new standard 4.10 rear axle. The previous 3.73 axle remains optional. Also new are an available spray-in bedliner and the expansion of the bi-fuel gas/CNG 6.0-liter V8 to the 2500 model line.
With its powerful 6.6-liter Duramax turbodiesel V8 hard at work under the massive hood, we discovered our 2014 GMC Sierra 2500 HD had no trouble at all towing a 10,000-pound trailer. A viable option to the gas V8, the turbodiesel churns out a healthy 397 horsepower and an even more astonishing 765 lb-ft of torque. For those taking notes, that's more horsepower but less torque than the Ram HD and less horsepower but more torque than Ford's Powerstroke diesel. As the towing and payload wars heat up, Ford's F-450 and Ram's 3500 currently take top marks for max towing, yet the Sierra beats the Ram in the area of conventional towing and payload. In our extensive testing of the complete Sierra lineup in rear-wheel drive and 4-wheel drive iterations, we found all the trucks exhibited a firm yet comfortable ride, acceptable steering feedback and excellent stopping power.
A feature we really came to love is the diesel powertrain's "smart" exhaust braking. The system works by progressively restricting exhaust output, which in turn helps slow the truck via engine-compression braking.
Offering a cleaner-burning alternative to gasoline, the bi-fuel CNG (Compressed Natural Gas) engine offers the ability to power the 2014 GMC Sierra HD with a readily abundant domestic resource. The lofty $11,000 premium might turn some away, but with CNG running under $2 a gallon, the savings over the long haul might prove fruitful.
