Volkswagen won't ever make a sports car, i think you can forget about that. Their sport car is the Golf GTi, and possible the Golf R. Like it has always been.
Also, Volkswagen has a line of work to be more "serious", more "blend in" lines, their cars will never be "exciting" If you notice, they never were, apart from their concepts.
And the reason of that is, Volkswagen is linked to cars that are reliable and cheap, popular vehicles... they get money of sports cars with Audi and all the other brands they have under their belt. Why make a VW that fights the Cayman for example? It is not interesting in the market point of view.
Toyota in the other hand, had sports cars before, MR2, Celica, Supra, AE86... and the GT86 is just a way to bring that heritage back... in the market point of view, Volkswagen already has a rival for the GT86, which is their Golf GTi.
To sum it up about their design, someone who buys a VW, buys it because it is "boring", basically. It is like a Corolla, nobody buys a Corolla, wanting it to be a Civic Si Coupe. :lol:
