2017 GMC Sierra 2500HD All Mountain Concept
About the best means of transportation on snow-covered mountain trails is a Snowcat – those machines that cross between a tank and snowmobile. The only problem is luxury or that vast lack thereof. Well, GMC now has an answer for this frigid conundrum. Meet the 2018 GMC Sierra 2500HD All Mountain Concept.
This one-off monster is basically a Sierra 2500 with a ton of upgrades, but its foundation is familiar. The truck runs the new-for-2017 6.6-liter Duramax turbodiesel V-8 with a stump-pulling 445 horsepower and 910 pound-feet of torque. The Alison 1000 six-speed automatic transmission and two-speed transfer case are responsible for shifting gears while five people can ride in the leather-lined crew cab. Naturally, GMC started the concept build with a Sierra Denali, meaning nearly every available feature and amenity comes standard. Oh, and of course heated seats and a heated steering wheel are included.
