7. BMW GINA
– Probably one of the most unusual cars ever built is this BMW which is entirely made from Spandex. The GINA Light Visionary Model is a fabric-skinned shape-shifting sports car concept built by BMW. It was designed by a team led by BMW’s head of design, Chris Bangle, who says GINA allowed his team to “challenge existing principles and conventional processes. Its doors open in a butterfly style, and are each covered by a fabric piece reaching all the way from the nose of the car to their trailing edge which when closed leaves a perfectly smooth surface.
