The Cocoon was a 6 passenger concept with three rows seats. The rear seat was bench-based while the remaining two rows were individual seats seperated by a console. Each seat was individually lit via large ceiling-mount indirect lighting to allow passenger adjustments. The driver was able to utilize a Heads-up display and the vehicle included a system to spray a refreshing scent via the steering wheel should the driver be getting sleepy. Per Allan Flowers, Nissan Design Studios, the concept was a SPHERE which encompased the seat back, door inners, headliner and instrument panel surfaces - creating a "cocoon-like" feeling for each passenger.
