Scirocco 3 from 2005 as it appeared in Autobild.
I believe it's only a rendering and never was a real car.
It is a proposal for the new Scirocco, yes.
I have it as a different year, but that might refer to when the car was scheduled to appear rather than the date of this proposal, so I'll give you the point for this.
I wasn't sure whether it was just a rendering or whether one was made, but I did think if they had actually made one, even a mock-up, it would probably have been better known than this.
Here are pictures of the proposal; the lack of any background might indicate that it's only a rendering, but it's a very good one!:
