Destroy the powder in the GMC Sierra All Mountain Concept
I can't imagine it would be comfortable on the street.

GMC's All Mountain Concept was built specifically to tackle snowy inclines.
Not only does it sport the equipment to handle that task, it looks like it's ready to beat up the mountain and ask for its lunch money.
GMC replaced the wheels with a set of Mattracks 150 Series tracks, which provide superior traction away from the pavement.
You probably wouldn't want to try out this bad boy on actual streets.
The concept also sports Thule snowboard racks, a whole bunch of bright vinyl graphics and LED lights under the body.
What fun is a concept without garish vinyl and LEDs galore?
Under the hood is GMC's tried-and-true combination of a Duramax 6.6-liter diesel V8 and an Allison six-speed automatic transmission.
The Duramax puts outs 445 horsepower and a pavement-twisting 910 pound-feet of torque.
The automaker built this concept to highlight its partnership with Vail Resorts.
The concept will remain at Vail throughout the winter season.
Good luck trying to convince the Range Rover types to go for something like this, though.
