Aesthetically, the single render uses the current Opel Corsa OPC as a base with the basic apperance remaining unchanged all the way to the B-pillar, before adopting the same wraparound, bubble-like rear window of the first generation model.
It is however highly unlikely that Opel parent company PSA will see it fit to re-introduce the Tigra as either a coupe or small drop-top in the case of the last model anytime soon.
