Active Sound Design delivers precise feedback.

M5 drivers will be given an even more direct reminder of their car’s performance capability by technology that brings the distinctive sound of the high-performance V8 – in all its glory – into the cabin of the new BMW M5.

The Active Sound Design technology specially developed for the new BMW M5 takes its cues from the driving situation at any one time to deliver an accurate reproduction of the engine’s sound through the car’s audio system.

The system’s digital signal processing exchanges data directly with the engine management, allowing it to reflect the engine’s revs and torque, and the car’s speed over the road. The result over a smoothly driven journey is a discreet soundtrack in keeping with the harmonious and assured characteristics of the V8 powerplant. A stamp on the accelerator, meanwhile, prompts an immediate audible response to match the instantaneous – and typically M – burst of power from beneath the bonnet.

In generating its signals, Active Sound Design takes its cues from the firing sequence of the eight-cylinder engine and the frequency range of the exhaust system. This gives the driver an extremely accurate impression of current engine load and an even more intense sensation of the V8’s high-performance characteristics. At the same time the Active Sound Design control unit ensures an even spread of sound across all five seats of the new BMW M5, while observing the legal guidelines governing noise emissions inside and outside the car. The characteristics of the sound produced by the technology also adjust to the engine settings selected by the driver. For example, switching to “Sport” or “Sport+” mode sharpens not only the engine’s responsiveness but also the acoustic experience inside the car.

    Cars need less electronics, not more.

    BMW needs to go back to basics.
    No steering assist, not brake assist, no stability management, no climate control, and 750kg max.

    Less is more.

      Sometimes you need to understand, this is not a full performance purpose built car. This is a performance executive saloon so we need all these stuff. If you want a more driver oriented saloon you can always go for the M3 or the equivalent. Furthermore, BMW needs those advanced electronics stuff otherwise Mercedes and Audi or perhaps the massively improved Jaguar could overcome BMW with their latest electronics technology. Surely BMW doesn’t want to fall back down right?

      It’s getting difficult to build cars nowadays and to stay ahead of the competitions…

      • Mateozunic says:

        exactly, that is the problem, TODAY 550i is enough SPORTY – who needs 560 hp in a saloon??? BMW should took M to next level, M3/5/6 should be hardcore performace cars, not like M3 CSL but with lot less electroncis than F10 M5, and for everyday M cars make this : 560i M sport N63 tun to 500 hp. 340i M sport 350 hp (in US theres already 335iS and Z4 sDrive35 iS) and so on!

    so what happens when you turn the speaker volume down, or off? no more cabin engine sound?  lol

    the obvious preferred solution is to simply remove some of the noise dampening, saving some weight in the process. the problem is the target market – it has a high percentage of fatcat executives and their trophy wives who can’t deal with a little tire noise. so, you get this instead.

    just remember, ultimately BMW is beholden to the shareholders and the bottom line. a sad but undeniable reality. our best hope is for occasional “halo” products like the CSL…

  5. My opinion to this pseudo-interior noise thing?

    My Answer, The same thing 3 words those Trolls on YouTube say.

    Just buy a Camaro SS if you want a muscle car sound.

    If you want wimpy sound stick with your Bimmer.

    can this item be sold separately and installed in any other car?

  13. bmw m5 says:

    so instead of buying the car i can go and buy the cd?

  14. Kevin M. says:

    Why this saccharine and masturbatory technology even crossed the engineers’ minds is beyond me, but the fact that it’s actually in the car is unbelievable. 

  15. Mbrund says:

    I want a car that does not cost a fortune.  Its this type of cr@p that adds to the cost by gives no value.
