[Twitch Massacre]

I'd be really surprised if there were any kind of truth to this. That picture looks like one of the unofficial renderings made for the F13 M6 before people knew what it looked like mixed with F30 design cues, and 2017 sounds way too early for a new model. M cars usually have a 5-6 year lifespan and a 1-2 year gap between model new generations. 600hp also sounds very odd for a power bump. I'm think this has little to no truthfulness. Pure speculation.
