That is a picture of the Ford Focus RS with the word "Police" on it in Swedish.
The spy photo was taken at the Contintental testing facility in Arvidsjaur.
Not much is known about this mysterious sighting. So I'm interested to hear your theories.

Sure, impersonating a police car is obviously against the law, but perhaps this is a piece of trolling used inside the test center.
Come to think of it, not spending too much time on public roads means this Focus RS can probably get away with these misleading white stickers.
