There must be something about the Chicago Auto Show that brings out Nissan’s creativity. Two years ago, the Japanese automaker unveiled the Winter Warrior Concepts, a collection of outrageously engineered Pathfinder, Murano, and Rogue SUVs that featured snow tracks instead of actual wheels. This year, Nissan is returning to the Windy City with a pair of concepts that might as well be spiritual successors of the Winter Warriors. One of these concepts is a fresh take on the Nissan Armada, called the Snow Patrol. It’s not as outlandish as the Winter Warriors or its present counterpart, the Nissan 370Zki, but the Armada Snow Patrol is unique in its own right for a variety of reasons.
