Subaru Impreza WRX STI Spec C Spied?S

If the previous generations were any indication, you'd expect an even more hardcore version of the Subaru Impreza WRX STI to be on the way in the form of a Subaru Impreza WRX STI Spec C. And breathe. Yes, which each new name expansion, the humble Impreza becomes mutated progressively more into a merciless monster. This new shot shows what appears to be the Spec C exposing itself in the wild, but we're not so easily convinced.

The image comes from Japanese magazine CarTop, and is claimed to be a hardcore Spec C testing on the Nürburgring. We're a bit skeptical because there appears to be no attempt whatsoever to disguise the car with any sort of camouflage. Real or not, the sad fact is that we may not even get the Spec C version on American shores when the rally star does make it to production.
