GM introduces the 2015 GMC Sierra All Terrain HD

Article by Christian A., on May 21, 2014

GM officially introduced the 2015 GMC Sierra All Terrain HD, a vehicle that wants to help its customers tackle tough jobs more comfortably. The 2015 GMC Sierra All Terrain HD is set to go on sale this summer and is available on 2500HD and 3500HD double cab as well as crew cab models, and it is offered with SLE or SLT trims.

Moreover, all models are offered with 4WD, including an electronically controlled transfer case. In addition, the vehicles are offered with the Z71 Off Road package, with Rancho twin-tube shocks, hill descent control and a skid plate.

As you can easily see from the photos, the 2015 GMC Sierra All Terrain HD comes with exclusive design features such as a chrome surround on the grille, exterior graphics, underbody shields made of aluminum, as well as unique 18-inch six-spoke chrome cast-aluminum wheels.

On 2500HD GM offers 20-inch chrome aluminum wheels, while the 3500HD models include adjustable outside camper mirrors with a chrome cap. Still, this is not all as the 2015 GMC Sierra All Terrain HD is also offered signature headlamps, body-color bumpers or chrome bumpers, chrome mirrors covers, body side moldings and chrome front-lower bumper plate.

Inside, we find the ‘All Terrain’ logo on the instrument cluster and a carbon fiber-inspired theme. GM offers as standard a rearview camera system. Other features included are the IntelliLink and new Onstar with 4G LTE and standard built-in Wi-Fi hotspot. The SLE and SLT versions get new, heated, power-adjustable trailering mirrors.

For the 2014 model year, the new GMC Sierra will be available with a host of active safety features such as Forward Collision Alert that employs a forward-facing camera to warn the driver of a possible collision. Also included is a Lane Departure Warning that employs the same camera to track the Sierra’s position in relation to the lane markers on the road. Popular Mechanics recently named this camera technology as one of the "Top Ten Tech Breakthroughs of 2012."

Along with Forward Collision Alert and Land Departure Warning, the Sierra is also provided with GMC's first-ever Driver Alert Seat that generates vibrating pulse patterns on the left and/or right side of the lower seat cushion bolster, thereby warning the driver of risks like when the truck makes an un-signaled lane change or approaches another vehicle too quickly. As per GM research, the vibrations on the seat could alert the driver on the location of a potential collision quicker and more accurately than sound warnings. Of course, drivers could choose between audible and vibrating alerts.

GM gave the 2014 Sierra a number of new aerodynamic measures that improve fuel efficiency while lowering wind noise. These include triple-sealed inlaid doors and wind turbulence-reducing mirrors, as well as roof and tailgate design elements that allows air to flow seamlessly and quietly over the new truck. Aerodynamic drag is further lowered through additional sealing around the grille and headlights as well as on the space between the cab and box. Furthermore, the new Sierra sports new aerodynamic spats in front of the rear wheels.

GMC Introduces 2015 Sierra All Terrain HD

GMC today introduced the 2015 Sierra All Terrain HD, a refined, off-road-inspired execution of the brand’s capability that blends exclusive design features with the versatility of 4WD. It goes on sale this fall.

“The new 2015 GMC Sierra HD lineup helps customers tackle tough jobs more comfortably, and with the new All Terrain HD, they can do it with greater style,” said Duncan Aldred, vice president of GMC Sales and Marketing. “Equally comfortable whether it’s a night on the town or traversing a remote job site, it has all the capability that customers demand from a GMC heavy-duty truck on the job.”

The new Sierra All Terrain HD is available on 2500HD and 3500HD double cab and crew cab models, and is offered with SLE or SLT trims – all with 4WD, of course, including an electronically controlled transfer case. Also included is the Z71 Off Road package, with Rancho twin-tube shocks, hill descent control and a skid plate.

Sierra HD’s 6.0L gas engine is standard and the Duramax turbo-diesel is available.

The All Terrain’s exclusive design features include a chrome surround on the grille, exterior graphics, aluminum underbody shields and unique 18-inch six-spoke chrome cast-aluminum wheels. Twenty-inch chrome aluminum wheels are available on 2500HD, while 3500HD models also include adjustable outside camper mirrors with a chrome cap.

Additional exterior content includes light-emitting diode signature headlamps, body-color bumpers (chrome bumpers available), chrome mirrors covers and body side moldings and chrome front-lower bumper plate. Inside, a carbon fiber-inspired theme distinguishes the All Terrain from other models and includes the ALL TERRAIN logo on the instrument cluster. A rearview camera system also is standard.

The new All Terrain HD also includes the latest connectivity technology, including IntelliLink and new OnStar with 4G LTE and standard built-in Wi-Fi hotspot. Enhanced features for IntelliLink include Text Messaging Alerts for smartphone users with Bluetooth profile (M.A.P.), which reads incoming texts through the vehicle’s speakers, and Siri Eyes Free for iPhone iOS 6 and iOS 7 users to enhance connectivity and convenience.

New OnStar with 4G LTE connection provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a three-month/three-gigabyte data trial.

Additional new and enhanced features introduced on the 2015 Sierra HD lineup include:

  • CornerStep rear bumper, EZ Lift and Lower tailgate, standard locking tailgate, standard upper tie-downs and other features that make cargo handling easier
  • Standard StabiliTrak with Trailer Sway Control on all models
  • Integrated cruise control, auto grade braking and diesel exhaust braking, for greater driving control and reduced brake wear on grades
  • Enhanced cooling airflow, which enables the Duramax turbo diesel and 6.0L gas engine to better maintain full power, even under heavy loads and high ambient temperatures
  • New Duralife™ disc brake rotors that offer up to double the service life (late availability).
  • New, heated, power-adjustable trailering mirrors are offered on SLE and SLT – including All Terrain – and Denali (late availability), including segment-first back-up lamps. The large mirrors feature 51 square inches of flat mirror surface positioned over a 24.5-square-inch non-heated or power-adjustable convex mirror surface. A new auxiliary back-up lamp is integrated in each mirror to enhance trailer visibility when backing up, as well as an amber auxiliary clearance lamp. The SLE trailering mirror is black and can be extended and folded manually. The SLT/Denali mirror has a chrome cap and adds a power-folding feature.

The 2015 Sierra HD also offers segment-exclusive safety features such as forward collision alert, lane departure warning with an active safety seat, and front and rear park assist. Head-curtain and seat-mounted side airbags are standard on 2500HD and available on 3500HD models.

All models are backed by GMC Pro Grade Protection, with two years of scheduled maintenance – including diesel exhaust fluid – a three-year/36,000-miles bumper-to-bumper warranty and a five-year/100,000-mile powertrain warranty.
