No doubt about it, it's been a cold, snowy winter in the upper Midwest -- and for the Chicago Auto Show, Nissan set out to do something about it.

The automaker unveiled two concept vehicles aimed at demonstrating how its cars can be loaded up with accessories.

The more eye-catching of the two is a Nissan 370Z Roadster that's been turned into a 332-horsepower snowmobile, of sorts. The rear wheels have tracks like on a tank or bulldozer and the front wheels have skis. The result is that it can go skidding through the drifts.

It's called the 370Zki, as in 370-ski.

The Armada Snow Patrol, as the concept is called, has been given extras like three-inch suspension lift, extreme off-road tires, massive front bumper, light bar and a roof rack.

"Every year we try to bring some unique winter show cars and trucks to Chicago, which is the nation's most-attended consumer auto show. This year we've outdone ourselves with the vehicles and the show space itself," said Dan Bedore, a Nissan spokesman, in a statement.
