GMC Concept Takes on the Snow
As everyone knows, concept vehicles are generally cool, and the 2018 GMC Sierra 2500HD All Mountain concept takes that temperature metaphor to the next level, as it has replaced its 20-inch chrome aluminum wheels with Mattracks 150 Series Tracks that have been given a GMC Red finish. That’s right: tank-like tracks instead of tires, so this truck—based on a Denali 4WD Crew Cab platform, so it has a 6.6-liter Duramax turbo-diesel that produces 445 hp and 910 lb-ft of torque that’s mated to an Allison 1000 six-speed automatic—can handle snow better than the Yeti. And having the Denali trim means that it is inviting inside even though it may be blustery outside.
Carl Zipfel, GMC exterior designer, says of the vehicle: “The Sierra All Mountain concept Mattracks technology enables the truck to conquer uncharted territory while highlighting premium interior features such as Bose speakers and upscale leather treatments.”
Yes, you can crank “Jingle Bells” and move in the vehicle.
The All Mountain concept is being stationed at the Vail Mountain resort (yes, there is snow there right now). While it is functional, it will, according to a GMC spokesperson, “be used mainly as a display property.”
Still, one can imagine it dashing through the snow in a far more comfortable and capable manner than a one-horse open sleigh.
Generally, when OEMs produce aluminum engine blocks (aluminum rather than cast iron because cast iron weighs like cast iron), they insert sleeves into the piston bores—cast iron sleeves.
While aluminum vs. steel is getting more contentious in the world of light-duty trucks, when it comes to creating structures, the heavy-duty truck people know something important about strength and mass.
