This is just an Internet rumor for now, but not only it makes a lot of sense, it’s actually necessary for the upcoming Audi RS7 to get 600 hp. I mean with the CLS63 having 550 hp – with the AMG pack – and the next M5 said to have even more power, if Audi wants to keep up with them they should come up with the same sort of power. It’s not likely for the RS7 to win beauty contest, specially compared to the new CLS. So, we can only wait and see what the Ingolstadt-based company have in mind for their upcoming high-end high-performance four-door coupe.
