BMW Press Release

August 27, 2015.
In terms of power and performance, modern BMW diesel engines are on par with the brandís petrol engines Ė only with regard to the desired sound are there any noticeable differences. In order to compensate for this acoustic difference, BMW is now offering the BMW M Performance exhaust system Active Sound. This new complete system comprising exhaust, sound system and control unit was developed exclusively for diesel-powered vehicles of the current BMW 2 Series, 3 Series and 4 Series and is perfectly attuned to the basic acoustics of each engine. The sound can be individually controlled via the Driving Experience Control function: In the ECO PRO and COMFORT modes, the system produces a clear, transparent sound that is suitable for long distances, is always convincing in day-to-day traffic and underscores the carís dynamic appearance. In the SPORT or SPORT+ mode, the Active Sound System unfolds its entire acoustic spectrum, ensuring maximum emotionalism. Therefore, BMW offers drivers with sporting ambitions in particular the opportunity to further individualise the engine sound and their vehicle as a whole.

In addition to the sporty acoustics, the look of the new sports exhaust system is also striking, as the dual exhaust with chrome BMW M Performance tailpipe trims blends in perfectly with the vehicleís design. In conjunction with the BMW M Performance exhaust system Active Sound, vehicles with 18d engines and all 20ds produced before July 2015 are fitted with an additional tailpipe. The more powerful engines are visually enhanced by a larger tailpipe diameter.

The system, which was developed by BMW, is produced in Germany and fulfils the brandís high quality standards with regard to the choice of materials, design and craftsmanship. Additional approval or entries are not required.

The BMW M Performance exhaust system Active Sound is available for the following vehicles and engines:
  • BMW 2 Series Coupe and Convertible (F22/23): 18d, 20d, 25d.
  • BMW 3 Series Sedan and Touring (F30/31): 18d, 20d, 25d, 28d, 30d, 35d.
  • BMW 4 Series Coupe, Convertible, Gran Coupe (F32/33/36): 18d, 20d, 25d, 30d, 35d.

Market launch of the BMW M Performance exhaust system Active Sound for the above mentioned models will be carried out successively from September 2015 to March 2016.

Based on what's written, it's an exhaust system, and the Active Sound speaker and control module. Are there any power gains?

if this is only interior sound with no power gains or exterior acoustic change - then what's the point?

answer = no point what so ever

It's a cosmetic mod. An acoustic cosmetic mod, but a cosmetic mod nonetheless.

Outside it will be a dual tail pipe
Only 16d models will keep the single one which is very good!

It's worth it to me just to get a dual exhaust. BMW's don't look right with a single tailpipe

that's a good one

but my point was really the sound issue. if its only interior sound what's the point.

I get the cosmetic mod for the exhaust, but the point is the sound. needs an exterior sound difference. what's the point of just pumping the exhaust sound to the interior? I don't get it.

Where do you read that it is interior sound only? When I look at the pic of the system I see a round part that has a bung for a vacuum line and then some sort of exhaust port off of the dome. So my guess is there is a valve in there and when you are in Eco and Comfort it is closed but sport and sport + open the valve creating more sound.

This looks a lot like the exterior active sound on the i8. BMW hides the active sound speaker inside a fake metal "exhaust tip" (not visible from outside but if you have the car on a lift, look up around the left side of the rear bumper and you'll see it up there). Our guess is this: putting a speaker inside a fake exhaust tip that plays exhaust noises makes it sound more realistic due to the way the sound waves react to that metal tubing, the same way exhaust sound waves react with normal exhaust piping.

Yeh it looks like there is sound in the exterior as well as interior just like the i8.
