Nissan's exhibit at the North American International Auto Show has a literal halo around it. The Nissan stand may likely be one of the most quirky and distinctive the Detroit Auto Show has seen in some years, featuring a 145-foot long illuminated ring that appears to float above the cars, trucks and crossovers Nissan will be highlighting. Meanwhile, the maker also hopes to lure show-goers away from the competition, quite literally grabbing them by the nose using what it describes as “special scent” matched by alluring sounds and music.
