GMC Sierra HD Adds Off-Road-Inspired All Terrain Package

Motor Trend logo Motor Trend 5/21/2014 Alex Nishimoto

GMC's off-road-inspired All Terrain package for the Sierra is expanding to Sierra HD models. Just as it does for the Sierra 1500, the All Terrain variant adds unique styling, standard four-wheel drive, and other features that help improve off-road capability.

The All Terrain package is available on 2500HD and 3500HD models in SLE or SLT trims, and for both double cab and crew cab body styles. The 2015 GMC Sierra All Terrain comes standard with four-wheel drive, and includes an electronically controlled transfer case. Also standard is the Z71 Off-Road package, which includes twin-tube shocks, hill descent control, and a skid plate. The All Terrain HD gets the 6.0-liter gasoline V-8 engine as standard, while the 6.6-liter Duramax turbodiesel V-8 is available. 2015 GMC Sierra HD All Terrain With Sierra And Canyon© Provided by MotorTrend 2015 GMC Sierra HD All Terrain With Sierra And Canyon

The package includes a chrome surround on the grille, unique exterior graphics, special 18-inch alloy chrome wheels, and aluminum underbody shields. A set of 20-inch chrome wheels are available on 2500HD models. All Terrain 3500HD models get adjustable side camper mirrors with chrome caps. LED headlights, body-color bumpers, and chrome exterior trim are also standard. Faux-carbon fiber trim is used inside the cabin, decorating the gauge cluster and center stack, which features a standard Intellilink infotainment screen with rearview camera. GM's new OnStar with 4G LTE comes with a built-in wi-fi hotspot as standard (the first three months are free, after which a subscription is required), while the Intellilink system gets text message reading ability and Siri Eyes Free iOS integration for 2015. 2015 GMC Sierra HD All Terrain Interior Door Sill Plate© Provided by MotorTrend 2015 GMC Sierra HD All Terrain Interior Door Sill Plate
