I think a lot of that is just to advertise the car ("this the future, people!!"). For example, the article notes how large parts of the F 015 is made of "plastic that changes shape in hot weather", which Mercedes (or any other self-respecting auto brand, for that matter) is never going to put in their actual cars that they sell.
So I don't think we can take the cosmetic aspects too literally as to what Mercedes' design team will actually go for with the final product.
