Arriving at dealerships this summer 2014, the new 2015 GMC Sierra All Terrain HD sets out be a refined, off-road rooted 4WD truck combining some exclusive design features. Powered by the standard Sierra HD 6.0L gas engine, with optional Duramax turbo-diesel powerplant, the new Terrian HD finds exterior graphics, grill surrounded by chrome, and 18-inch six-spoke chrome cast aluminum wheels, to name a few exterior appointments.
The new Sierra All Terrain also includes IntelliLink and new OnStar with 4G LTE and standard built-in Wi-Fi hotspot along with the latest connectivity inputs. 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.
Segment-exclusive safety features on 2015 Sierra Terrain HD include 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.
