Autocar said:The GINA roadsters flexible, stretchable fabric skin is a man-made product that resists water, high or low temperatures and doesnt swell or shrink. The essential shapes are formed beneath the skin by a metal wire structure, though at points where movement is needed (ducts, door openings, spoiler) flexible carbon struts are used.
Though the GINAs skin appears seamless, it can, for instance, grow a higher rear spoiler for stability at high speed. The doors are each covered by a fabric piece reaching all the way from the nose of the car to their trailing edge. When closed, they leave a perfectly smooth stretched surface.
This concept, really clarifies an article that I read in the Winter 2006 BMW Magazine and that I didn't pay all that much attention to at the time.
The article itself explained the concept of (the now available) Efficient Dynamics, however there was a vague paragraph regarding aerodynamics, in particular how they're working on aerodynamics that automatically adjust to the speed of the car. Given the somewhat platitudinous nature of that comment, I'd barely given a second thought to the potential ramifications of such a statement.
And it would appear that I was very mistaken in doing so.
