Chris Bangle, head of design for BMW, says GINA allowed his team to “challenge existing principles and conventional processes.”

“It is in the nature of such visions that they do not necessarily claim to be suitable for series production,” company officials said in unveiling the car Tuesday. “Rather, they are intended to steer creativity and research into new directions.”

Instead of steel, aluminum or even carbon fiber, the GINA Light Visionary Model has a body of seamless fabric stretched over a movable metal frame that allows the driver to change its shape at will. The car — which actually runs and drives — is a styling design headed straight for the BMW Museum in Munich and so it will never see production, but building a practical car wasn’t the point.
