I was driving through Wilton, CT on Route 7 on Friday and i saw for the first time with my own eyes an F10 M5. I was directly behind it at a light and when it accelerated, it sounded like a V8 M. It was more subdued than the S65 and the previous M5 but without a doubt, it had that growl. Now, i dont know how this 6 would sound in comparo but i was pleasantly surpised at the sound and wondered why they even bothered to put that in cabin engine sound.
