With a futuristic design and technological innovations it "highlights how cars can be part of a networked world." Antennas replace side-view mirrors and transmit information to the outside world, capture navigation data and assist in monitoring traffic and the environment around the car. It also has a 3-D head-up display that fuses the view of the road ahead with virtual content.
