For tackling the most treacherous snow-covered terrain, GMC has created the Sierra All Mountain concept. Debuting in late 2017 in Vail, Colorado, the extreme truck hasn't been confirmed for production. But we'd love to see it make its way to market, for a whole host of reasons as described in the video above.

Some of the biggest highlights on this truck include Mattracks finished in red, unique bodyside graphics, and a 30-inch light bar. Under the hood is a 6.6-liter turbodiesel V-8 engine making 445 hp and 910 lb-ft of torque. The engine is mated to a six-speed Allison automatic transmission. Despite all the exterior modifications, the model shares its bones with the standard GMC Sierra 2500HD Denali 4WD Crew Cab.

Check out the video to see the GMC Sierra Denali HD All Mountain concept in action.
