Call Chicago the 'Snow Show'

GMC equipped a heavy-duty Sierra concept pickup, above, with four tank tracks.

It's the inevitable risk of holding a major auto show in a Northern city in the dead of winter: It might snow. And it usually does — if not while the national media are in town kvetching about the cold, then certainly when the public is invited in to kick tires.

Nissan's concept roadster has rear-drive tracks and front skis.

At this year's Chicago Auto Show, it looked like some automakers were ready for it. Nissan used the show to highlight a one-off concept roadster it called the 370Zki, which traded in the 2018 370Z's four wheels for a set of rear-drive tracks and front skis. General Motors' GMC brand showed a heavy-duty Sierra concept pickup it called the "All Mountain," equipped with four tank tracks instead of wheels. Rival Ford kept the wheels on a heavily-modified F-550 Super Duty, but added more of them for increased heft and traction.

Ford's F-550 Super Duty didn't trade in its wheels — it added more of them.

Any of these vehicles would be immune to all but a cataclysmic snowfall — maybe even a snow-pocalypse. But it's important to remember that, even in the clutches of winter's icy grip, pitchers and catchers of all MLB teams report this week for spring training.
