Re: New M5 Sound
Can't help me, it sounds noisy enough but still like a exaggerated Golf GTI with a cheap aftermarket exhaust. There's nothing to hear from a well composed V8 growl. Yes I know, w're talking about a biturbo engine and therefore about limits in the development but still.....
Compared to the X5/6 M it's an improvement of course...

It sounds better than on the X5/X6M but still... 
A SUV needs a deep V8 growl, the tuned GTI sound is more suitable for the M5.

Re: New M5 Sound
WAY:
Have you guys listened to the AMG's new bi-turbo engine? Why is it that AMG can develop a great sounding turbo engine but no one else seem to be able to???
Very good question!!
Don't understand BMW's sounddesigner. We often get told that this depends on the very special manifold which delivers the spontaneous acceleration at low revs.
Apparently Mercedes could solve the problem

BMW uses, from my memory as the only manufacturer yet, an exhaust manifold that lies within the V of the two cylinderbanks and distributes the exhaust gases of both sides to the two turbochargers, instead of one charger per cylinderbank. Due to the layout the response of the turbochargers is said to improve but on the other hand it alters the exhaust sound significantly.
I have no background information but assume that on the 997 Turbo, the newly established VTG chargers demanded a careful setup of the exhaust backpressure which would naturally be more complicated if the exhaust is using actuated flaps as on the PSE system. Whether it is due to Wiedeking´s economical considerations or not, it would significantly increase the price but obviously is a tad too civilized for a few customers.
The new V8 biturbo from AMG indeed features a great sound, it was certainly necessary to finetune the sound but the engine itself offers a solid basis for that.

Maybe it has something to do with company "exhaust sound philosophy" ?
Currently, I wonder if a loud exhaust sound is actually a good thing.
Let me explain why:
I was driving our Countryman Cooper S on the same street I usually drive my 997 Carrera GTS with PSE. This street has a 100 kph speed limit and connects two small villages but it is actually not outside, it is difficult to explain. Apparently they "forgot" to post a speed limit.
Usually, I fully accelerate on this small portion of street and with the PSE flaps on all the time, this sound is just amazing. People walking on the boardwalk usually show me the finger or a fist...Germany at it's finest (keep in mind that I never drive faster than the 100 kph speed limit).
So I drove this very same street with the Mini Countryman Cooper S, doing the same, fully accelerating. Lots of people were on the boardwalk but none of them turned around or bothered to care, despite the fact that I was actually driving the same speed as in my GTS.
Bottom line is: Loud exhaust systems may sound nice for us but they are also screaming "here I come...". Not really good for a neighborhood where people aren't too fond of loud exhaust sounds.
So maybe a not so loud exhaust sound isn't that bad at all, especially in regions with people who seem to hate cars...as long as these aren't theirs.

Re: New M5 Sound
I never get that reaction in London when I keep the PSE on. People walking on the pavement look but don't say anything.
I often find other cars simply move aside on the A roads to let me past. I never ever get that when I'm driving my wife's BMW.

Hey RC, maybe the difference it`s in the car and not on the noise.... people do get envy with "porsche sounds" (same where in Portugal...)

The times they are a changing...
A loud and aggressive exhaust note is no longer widely accepted. There has been a certain jester's licence for extreme cars like Ferrari or Lamborghini for example, but in my opinion this is long gone. In times of soundless e-mobiles the (very) loud sportscars seem to be a dying breed. And to be honest, after many years with loud Italian cars (that even got louder over the years), I fully enjoy the brute but nearly silent power of the Turbo.

Re: New M5 Sound
I think this will go some way to ensuring at least the driver enjoys a good soundtrack!
