" the electronic noise (which BMW calls Active Sound) will instead simply be a real-time amplification of induction noises actually produced by the engine." So you see, a louder exhaust would not be a solution. Turbo cars muffle induction noise which is a small part of the overall noise produced by a car. BMW's solution is to use active sound to enhance those induction noises and deliver them directly to the cabin. |

My guess is that turbocharging tends to squelch the higher frequencies and are more bassy. Plus, the car is relatively well insulate, which tends to further suppress the higher frequencies more than the lower frequencies. However, the high frequencies are likely to be most helpful when trying to judge where you are in the rev range or how the engine is responding to the current load. As such, my first guess is that BMW is trying to equalize a little of what is suppressed by the turbos back into the cabin to give us better feedback. Most of us will either find it acceptable or enjoyable is my second guess. It will probably be a slightly refined version of the M5, which I haven't heard, since things tend to be improved along the way.

If it came from engineering, I'd agree. But if it came from marketing, who knows that pseudoprecision they would use?

BS! Why would you go to all the trouble and expense to get 2-3%? I don’t buy this

Whereas the M5 fake sound is more across the range, they probably realised it would be better to only concentrate on the high frequencies (ie. the 'rasp') and allow more natural noise through in the low range. Thus 3% is not a lie - but probably only in wave energy terms - you would still probably notice a difference when you turn it off, like when your tweeters blown. |

This is NOT WINE! It's grape juice with a label that "Vin, Appellation de Origine Controlle" but still freaking Welch's juice with 3% antifreeze and because it tastes OK, most of you are saying what's the problem with that? |

DO NOT LIKE!! Was so surprised by this! Dissapointed!!! those older vehicles (e46, e36 ///M3's) sound incredible without this active sound shit, unless they had something we didn't know about! Something I would expect Mercedes-Benz to do if they haven't yet.

I think the complaints about active sound are valid. What people want is what they've come to expect from the past. Sound is just like any other characteristic of the car. In the older cars (NA engines, I know) there was fantastic induction noise coming from trick airboxes or piping directly from the intake through the firewall. You could feel the noise in your chest on e85 z4 non-M models, and it would nearly shake the windshield. It's just not the same as noise coming from the speakers, synthesized or not. Let me put it this way: if they announced the next M5 would get an electronic "diff" a la 135i, people would understandably be upset, because it's a significant change in what most would say is the wrong direction.
...and BS on the 2-3%. If it were that trivial, they wouldn't have bothered. |

If you don't like how it sounds, change the exhaust, do the easily searchable-on-the-forums trick to disable active sound, or don't buy the car. The pseudoreligious whining about BMW losing it's soul has to go, though. Porsche built a SUV, and I'm still waiting for the promised mass suicide of 911 purists.

Try it, if you don't like it, either unplug it, change the exhaust, or don't buy it. So much engineering goes into these cars, I can't imagine it being a negative or deemed a waste for the vast majority of us. If you are the audio equivalent of a wine guy that can tell what side of the road the grapes were grown on at a vineyard in Bordeaux AND fret over that difference, this may not be the car for you. I will bet big dollars that you will be able to hear a very noticeable difference, and it will make sense, whether you like it or not. BMW isn't going to add mics, amps, audio processing, and speakers to a car in which they are desperately trying to keep the weight and manufacturing cost down for nothing or at the expense of detracting from the driver experience. I say run Chicken Littles, run.
Edit: Keto, We simultaneously posted. Excellent point on the acoustic trickery with mechanical means. |

Exactly, there is no way that is an accurate number. The ///Marketing team in effect again to make everyone feel good.
