Obiously I'm asking rhetorical questions.
I find Porsche is pretty backward when it comes to tech and engines. Once they start to gain access to Audi's tech, I will start to consider a Panny instead of an M5. Until then, it's no context imo.
My guess is that the next gen GTS will have the Audi S8 engine and it will be glorious.
