Opel Corsa OPC performance version spy shots from the 'Ring

This Opel Corsa OPC in a tuned version was spotted in tests at the Nurburgring where the prototype was being driven by Volker Strycek.
It has some changes compared to the OPC currently available, with larger Brembo brakes, new front spoiler, dual exhaust and new extractor.

The yellow colour with black roof is a new look too, all of which could indicate a performance version of the Corsa OPC, with a 1.

6-litre turbo engine and 192 hp.
