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.
