Narrow year range (drag arrows to filter):
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.
For 2013, extended-cab 2500 HD models equipped with the standard 6.0-liter V8 can be had with a new bi-fuel system that accommodates both gasoline and compressed natural gas (CNG). Two new exterior colors (Sonoma Red Metallic and Heritage Blue Metallic) round out the changes.
The 2012 GMC Sierra HD sees a few improvements for this model year. A new hard-drive navigation radio is offered, while Work Truck models gain cruise control and lockable spare tire. Denali trims gain as standard equipment heated and cooling front seats, a heated steering wheel, a rearview camera and, on 3500 dually models, 17-inch polished wheels.
The 2011 GMC Sierra HD's Duramax turbo diesel's power, torque, maximum conventional and fifth-wheel tow and payload ratings are best in class. Its fifth-wheel tow capability is 21,700 pounds, it can tow up to a 17,000-pound conventional load with its factory-installed hitch, and the Duramax is fully B20 biodiesel compatible.
Technical upgrades include the addition of Bluetooth hands-free communication technology to OnStar 8.0, as well as Destination Downloads for vehicles equipped with DVD navigation. Extended and Crew Cab trims offers a rear backup camera, while a stability enhancement system is made standard on the 2500 HD with single rear wheels.
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.

"Truck is stylish. Very quiet. Very little road noise. Pleasure to drive during the day. Has lots of nice features. HOWEVER, the headlights are absolutely terrible. Far too dim. Extremely hard to see on back roads. Wish I would a known this prior to purchase. Previous models have great LIGHTS. No excuse for this other other than poor engineering."

"Traded my 2011 Silverado for this 2014 Sierra Crew Cab SLT and what a difference. It's like a luxury vehicle inside. Smooth and extremely quite ride. It doesnt even feel like your driving a truck. And I can beat my buddies ECOBOOST on this V8 with a better tow rating. The only negative would say is with the 3.42 rear end the gas miledge isn't much better than the 11 but it is still being broken in so I'll give it some time."

"my truck is still new and not broke in, but i am very happy so far. i'm getting around 16mpg driving everyday (and i'm kinda hard on my vehicles, so this is good for me) and went on a recent trip and got almost 21mpg. the interior is set up user friendly, and is very quiet going down the road. some of the new features (steps in bumper, under-rail lighting in box, trailer brake controller, etc) are very handy. my only gripe so far would be if you actually use this vehicle off road, the new wheel-well liners are a pain to clean once dirty (they are some sort of carpet material, i'm sure this has something to do with road noise)."
