GMC Goes Official With The 2015 Sierra All Terrain HD

The majority of GMC HD pickups end up leading rough lives going to and from job sites, but after announcing the upscale 2015 Sierra All Terrain HD, the brand has a truck which is equally as comfortable in the valet parking spot as it is at the construction site.

The new Sierra All Terrain HD, available in conjunction with SLE and SLT 2500HD and 3500HD double cab and crew cab models, comes with standard four-wheel drive and the Z71 Off-Road package, which adds Rancho twin-tube shocks, hill descent control and a skid plate.  Engine offerings remain the same as regular HD models with a 6.0-liter V8 as standard and an available turbodiesel Duramax offering.

Visually, the All-Terrain features a chrome surround grille, a chrome lower bumper, exterior graphics, chrome mirror caps and 18-inch chrome-cast or available 20-inch chrome aluminum wheels. There is also light-emitting diode signature headlamps and body-color bumpers, though chrome units are also available.

The interior of the All Terrain is distinguished by the carbon-fiber inspired theme, GMC says, and a special All Terrain logo on the instrument cluster. A rearview backup camera system is standard, along with General Motors’ IntelliLink infotainment system and new OnStar 4G LTE technology with built-in Wi-Fi hotspot capabilities. The hotspot is active whenever the vehicle is on and  the truck comes with a free three-month/three-gigabyte data trial.

One of the bigger changes on the All Terrain HD is the new, power adjustable folding mirrors, which are now available on SLT and Denali versions of the pickup as well. GMC says the mirrors feature 51 square inches of flat mirror surface and an integrated reverse lamp to help enhance trailer visibility when backing up. SLE-equipped models also feature a version of the mirrors which are black instead of chrome and need to be extended and folded manually.

“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,” Duncan Aldred, vice president of GMC Sales and Marketing, said in a statement.
