At least there isn't a trace of drone on the video lol! At this stage, they don't care about the exhaust sound I'm sure, and it's probably being worked on separately. Sad though, the s65 sounds way better. On the one video where the e92 M3 is following you can hear that engine difference and how the 6 cylinder engine sounds like crap.
Even the worst s65 exhaust systems sound better imho. I know, I know I gotta quit comparing the future vs the present.
Oh well, we'll have to move past that. It's a new world. Still sounds better than a prius or a leaf.
On the serious tip, it's looking great handling the turns.
