2015 GMC Sierra HD All Terrain Unveiled

GMC has just fanned the flames in the eternal truck wars with their latest offering, the 2015 GMC Sierra HD All Terrain. Now before you start bantering with your buddy with blind brand-loyalty logic, take a look at what the 2015 GMC Sierra HD All Terrain has to offer.

The 2015 GMC Sierra HD All Terrain will be available on 2500HD and 3500HD double cab and crew cab models in either SLE or SLT trims. Since going off-road into the unknown is pretty common among work trucks today, the GMC Sierra HD All Terrain is only available in 4WD with an electronically controlled transfer case. To soak up the rough dirt roads, the Z71 package is employed with a set of Rancho twin-tube shocks, hill descent control, and even a skid plate to keep the rocks away from vital engine parts.

While the 2015 GMC Sierra HD All Terrain doesn't have quite the off-road prowess of a modern Dodge Power Wagon, it is however offered with an optional 6.6L Duramax turbo-diesel V-8 engine for those who'd rather kick up some dust off the beaten path with the power of compression ignition under their hood. However, a 6.0L V-8 gasoline engine is standard in case you want the low-end grunt and roar of a naturally aspirated V-8 gasoline engine.

Exterior touches include a chrome surround on the grille, exterior graphics, aluminum underbody shields, and unique 18-inch six-spoke chrome cast-aluminum wheels. A set of 20-inch chrome aluminum wheels are also optional on 2500HD, while 3500HD models also include adjustable outside camper mirrors with a sleek chrome cap. A set of LED-signature headlamps are retained on the 2015 GMC Sierra HD All Terrain, while a set of body-colored bumpers give it a meaner overall appearance. If body-colored bumpers aren't your cup of whisky, you can also opt for chrome bumpers for a mild low-key appearance.

Creature comforts inside revolve around a carbon fiber-inspired theme that GMC says distinguishes the All Terrain from other models and include the All Terrain logo on the instrument cluster. We won't bore you with details on how much technology is packed to the hilt on the '15 GMC Sierra HD All Terrain, but suffice it to say that it can link to your phone and read your text messages to you while you cruise down the road. It also has a built-in Wi-Fi hotspot to keep you and your passengers connected to the web even while at a remote job site.

Speaking of remote job sites, the 2015 GMC Sierra HD lineup includes a CornerStep rear bumper for easy access to tools or materials, while a lockable EZ Lift and Lower tailgate and standard upper tie-downs make cargo handling a breeze.

Since the 2015 GMC Sierra HD All Terrain is a legitimate tow rig and not just a one trick pony, StabiliTrak with Trailer Sway Control comes standard on all models. They also feature integrated cruise control, as well as automatic grade braking and diesel exhaust braking to tackle the steepest grades imaginable while keeping the trailer under control, resulting in reduced brake wear on grades.

Since pulling up a long steep grade while towing a trailer can really tax power output, the 2015 GMC Sierra HD All Terrain features enhanced cooling airflow, which enables the 6.6L Duramax turbo diesel or 6.0L gas engine to better maintain full power, even under heavy loads and high ambient temperatures.

One thing that seems pretty awesome to us are the new heated and power-adjustable trailering mirrors offered on the SLE and SLT All Terrain models that include segment-first back-up lamps. These auxiliary back-up lamps are integrated into each mirror to enhance trailer visibility when backing up and feature an amber auxiliary clearance lamp. The SLE trailering mirror is black and can be extended and folded manually, while the SLT/Denali mirror has a chrome cap and adds a power-folding feature.

On the safety end of the spectrum, the 2015 GMC Sierra HD All Terrain offers segment-exclusive safety features such as forward collision alert, lane departure warning with an active safety seat (it gives your butt a quick buzz to warn you of any danger nearby), and front and rear park assist. Head-curtain and seat-mounted side airbags are standard on 2500HD and available on 3500HD models.

So now that you know what the 2015 GMC Sierra HD All Terrain has up its rolled up sleeves, is it really GMC's answer to the Ram Power Wagon? We think the answer is a resounding no, but the simple fact that this is available with a 6.6-liter Duramax turbo-diesel V-8 means its definitely got the potential to morph into a mean off-road machine.

The 2015 GMC Sierra HD All Terrain goes on sale this summer.
