Could have been, yes!
There's no Porsche parts in this, though, and it's not Mr. Colani's work.
Believe it or not, this is a very obscure piece of work from the design division of one of the world's major automobile manufacturers. And I have only seen it mentioned once - so I'm almost willing to believe that it's something else than it's supposed to be, but until the opposite has been proved, I want the manufacturer and model designation that I've been told is correct.
