According to Fox News:
Instead of a metal or plastic body, BMW's latest concept, the GINA Light Visionary Model, drapes a flexible fabric material over a moveable wire mesh frame, creating a nearly seamless surface that can alter its form at the whim of the driver.
If you're feeling frisky, you can raise the tail like an angry dog, bulge the fenders as if you've injected them with steroids and reshape the sides of the car to transform it from a sleek roadster into an intimidating racer.
