GMC has 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 summer.
“The new 2015 GMC Sierra HD lineup is designed to deliver class-leading capability with enhanced comfort and purposeful technologies, and the new All Terrain HD executes with greater styling enhancements,” said Michael MacPhee, marketing manager for GMC in Canada. “As a seamless extension of our customers’ office space, GMC HD trucks are equally comfortable whether on a remote job site or a night on the town.”
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 mirror
Additional exterior content includes light-emitting diode signature headlamps, body-colour bumpers (chrome bumpers available), chrome mirrors covers and body side mouldings and chrome front-lower bumper plate. Inside, a carbon fibre-inspired theme distinguishes the All Terrain from other models and includes the ALL TERRAIN logo on the instrument cluster. A rearview camera system is also 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 330 cm2 (51 square inches) of flat mirror surface positioned over a 158 cm2 (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, a three-year/60,000 km bumper-to-bumper warranty and a five-year/160,000 km powertrain warranty.
