The stunning Sport Sedan Concept embodies a number of next-generation Nissan design signatures, including V-Motion front aspect, distinctive "floating" roof and boomerang-shaped lamps. The Sport Sedan Concept shared the spotlight with the first North American appearance of the Nissan IDx Freeflow and IDx NISMO concepts. The two IDx compact concept designs offer radically different characteristics, each with their own unique identity. Also making its first North American auto show appearance in Detroit is the Nissan Autonomous LEAF prototype. Based on the all-electric Nissan LEAF, the vehicle is equipped with cameras, laser scanners and radar -- which identify nearby pedestrians, traffic lights, traffic signs and other objects. The Nissan Sport Sedan Concept, IDx Freeflow, IDx NISMO, Autonomous LEAF and the complete lineup of 2014 Nissan cars, crossovers, trucks and SUVs will be shown at the Nissan display at Detroit's Cobo Center during the run of the 2014 North American International Auto Show.
