2015 All Terrain GMC HD Sierras Coming To Market This Summer

GMC’s Sierra 1500 4×4 All Terrain package is such a big enough hit with consumers that the company is bringing out a similar trim package this summer in the new generation HDs.

The All Terrain’s exclusive design features the Z71 Off-Road package plus a chrome surround on the grille, special 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 mirrors with a chrome cap.

Additional exterior content includes light-emitting diode signature headlamps, body-color bumpers (chrome bumpers available), chrome mirrors covers and body side moldings and chrome front-lower bumper plate.

Inside, a carbon fiber-inspired theme distinguishes the All Terrain from other models and includes the ALL TERRAIN logo on the instrument cluster. A rearview camera system also is standard.

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

“Equally comfortable whether it’s a night on the town or traversing a remote job site, it has all the capability that customers demand from a GMC heavy-duty truck on the job.”

TheAll Terrain HD is available on 2500/3500HD 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. 

Sierra HD’s 6.0L gas engine is standard and the Duramax turbo-diesel is available.
