But this car is too similar with the Jetta (sorry, I meant Jetta, not Passat.. but does not matter at all, since all these cars are built on VW Group MQB platform). The engine, the transmission, the suspension, the interior all come straight from Volkswagen, isn't it? And even the exterior looks too common with Jetta, IMO. So I won't call this car something unique, nor a "donor" car.
But I don't see a reason for Skoda to unveil some serious sportscar. That's the deal for the master-Volkswagen, while Skoda should exactly orient on the afford-ability. Rapid Sport Concept (still a Jetta) made a hint on what performance Skoda might be, but that's too foppish, which is suitable for Skoda's stereotype. On the other hand, it does not look too much boring, and is a bit more eccentric. But for that reason Golf R already exists, which, BTW, will soon make a debut in MkVII face.
BTW, I don't really care about Octavia name, but translating "Škoda" from my mother-language, means "trouble". Nevertheless, people still buy them. :D
