Not sure why several of u guys kept saying this. AS adds in/amplifies the engine note only. The exhaust note is the real deal from the car's exhaust. If u change the exhaust, u simply replace the original exhaust note with your new exhaust. AS ain't gonna affect anything. It simply remains, but its sound would be drowned out by the louder new exhaust.

Makes a huge difference, however I'd rather fix the issue with a big honking exhaust

It would be funny if you notice that the intake, BOV isn't synchronizing with the active system.
except Porsche's is not a sound pumped through stereo, it's a valve that allows engine intake air to run through a by-pass valve, so driver hears the sound of the intake.

Idk what the formal term is but an easy and real fix would be a button to cover or uncover header/downpipe dump outs under the drivers and passengers side. That way it's either stock, or loud. No soundproofing would stop that sound. Probably not legal for the factory to do though

I think the real challenge isn't whether or not to use a valve to allow the sound to pass through into the cabin. The real issue is whether or not after going FI, does one still get enough induction note to enjoy in the cabin. The Porsches that use this method I believe are NA. I wonder how it sounds for the Panamera Turbo?

There's something just unnatural about cars like the M5 that requires these sorts of things. It's a balancing act between large, heavy luxury quiet car that they are trying to make as fast, handle as well, and provide similar feedback as a sports car. So they have to use these weird tricks to bridge the gap.

I think it's neat that BMW is offering this M5 beast. Yeah they could have used other tricks to get there as others suggested, but at least they are just amplifying the interior noise, not trying to make it sound like something it isn't.

First of thanks for taking the time to do this test. I had to put earphones on to really hear the difference. The first acceleration you can really here the enhanced sound of the engine.

One could come up with many theories why BMW did this. I think they just simply thought the car was too quiet inside and wanted to separate it a little more from the 550i.

The test drivers might have complained about the engine being to quiet, not able to physically hear where the revs were at. It could be possible that this feature is a lot more useful in a manual M5. It is helpful being able to hear the revs clearly and not having to constantly look at the rpm gauge.

I'm sure with a little bit of coding active sound can be turned off.
Instead of pulling a fuse which most people wouldn't want to do...

I don't think he is suggesting that people pull their fuses as he explained that the radio and the parking sensors also don't work with the fuse pulled. It was just his way of testing the difference in sound.

Correct! Yanking the fuse is the only way to disable Active Sound as BMW is not making this feature user selectable, at least not now. I certainly won't advise anyone to run around with the fuse yanked for reasons stated.

I actually like the noise pipe of my gti without it you just heard turbo whine and despite what people think I notices no increase in throttle response. Imagine active sound in the v10... They should add more microphones near the exhaust intake wastegates turbos and make a symphony so when you upgrade you can hear them... But there should be a I drive function to enable disable it. AS does give it kinda straight cut gear sounds

In a few years when every car is full electric, or electric with a range extender, technologies such as this will be commonplace. That BMW is pioneering it now is a good thing, and the result is that by the time we no longer have V8s or V10s to enjoy, we likely won't be able to tell.

I'm as much a "petrol head" as many on these boards, but I just don't see how we'll continue with our love of these engines. After driving lots of high-torque and low RPM engines, including everything from the 3.0 liter diesel in my X5 to an 8 liter V10 in a Viper Competition Coupe, I think that the instant torque of an electric motor is going to be great once the battery energy density issues are worked out, and they will be. Being able to have the car sound (and likely "feel" via resonators, etc.) like a V8, V10, V12, or whatever, will be great. Sure, it's "videogame" like, but most cars are and have been for a while now.

If you're not ready to embrace the future, there are always classic cars that you can buy, drive, and enjoy.

There are two other possibilities to deactivate Active Sound that can be tested.

1) Pull the plug out of the Active Sound Control unit ( May throw a error code ??)

2) Pull the connectors from the Active Sound Control unit to the Amplifier ( Top Hi Fi system)

Are u saying that there are 2 other fuses that control the above or that we disconnect some wires/connectors?

BINGO... VERY well stated... Sound will be just like the incorporation of things like "angel eyes" etc. that brand. Sound sculpting will be an afterthought when your driving Tesla-esque torque on a daily basis. ~Frost

Dear haters of the AS, I understand personally from your stand that as a BMW owner or enthusiast, you wish to have a choice or have various opinions on the system itself.

Perhaps you may even feel that BMW has diverge from its path of "Ultimate Driving Machine" and fell into the cult of "fake noise" generation.

However, please, I would like to urge you guys to spare a little thought to the hard work that the BMW and M-division Engineers. They try their every means to bring out the best to us and spent so much time to fine tune the little details for the vehicles out on the roads.

For those who question about "noise insulation", and why on earth should BMW drown out the noise from the outside and muffle the noise of the engine as well. Sit down, have a cup of coffee and think about why M-cars were developed in the first place. Under what category does the M5 fall in? I'm not sure if your answer's a Premium luxury sedan that can function as a track vehicle on weekends. But for the latter, it has to under go stringent engineering development in a field called "Noise Vibration Harshness".

In a nutshell, the engineers of this field goes through many hours to fine tune the tactile response for your seat, drive wheel and vibrations of your vehicle; as well as acoustic response for you and your passengers' ears. They are people who spent many years just to learn the art of doing so. And trust me, its one of the hardest department and a silent workhorse in the automotive industry.

The M5, in order to be luxury in its own right, has to be properly insulated from outside noise to a certain extend. Its targeted to customers who want to enjoy comfort as well as greater performance out of an normal F10 5 series. They are people who wishes to pay premium pricing to enjoy both side of the coins.

Indeed, BMW didn't admit to the fact that there is AS, but I guess its all for marketing purpose. For the purist, I guess you people just wish for them to be honest about it and be able to shut it off. Fair enough.

But I hope that the haters out there can just calm down a little and stop making a huge deal out of the matter. As smaller and economical engines hit the roads, we all have to get used to lesser engine audio. Want some hot rod V8 power? Get a different car. Everyone have a choice. If you wish to have a car that pleases you in terms of noise and harshness and produce the same amount of power, get the GTR or any close models that you can think of. Or you can remove the engine insulation at the front of your dashboard all together.

A car design can only please so many people. If it doesn't suit you, you can always check out the store next door. Just don't hate the car for not being suitable to your taste.

And artificial car sound is coming to town, we can't stop it. Even Audi has an audio department making exhaust sounds for the e-tron. Its the future of matters and if its hard to swallow, I wish to give you a pat on the shoulders.

No fuses, but the plug into the Active Sound Control unit or the wires from it to the amplifier.

All the sounds are generated buy the AS Control unit and then fed into the cars amplifier.
So I would think if you disconnect the connection between the unit and the amplifier you will not get any sounds.
