Porsche is not. They do not reproduce engine noise.

The sound symposer is simple a tube with a valve connected to the intake of the engine.

 

Chris,
the ISG is just a fancy term. it's all about how to channel the sound back into cabin. give me a tube from the back would do it. just that they have to find ways to have it covered by fancy carpet & grills.

 

Wait. So it's not artificial engine sound generated through the speakers?

There is a world of difference between a vacuum operated muffler bypass and reproducing engine noise through the speakers.

 

I know. But BMW is actually REPRODUCED (ARTIFICIAL) NOISE. With Porsche it's ACTUAL engine noise from the engine a few feet behind you. No speakers were harmed in the making of that noise!

 

i really don't think so, but i could be wrong? i'm just strictly talking from my ear. unless we see a diagram of the system, otherwise i would just think it's some active valves that opens & closes that connected to the audio system or other outlets. i drove it couple days ago. all the sounds are there. just different level when u're in different sitting (from N, S to T). nothing artificial i could hear.

 

I see.

Well, if it's a traditional muffler bypass I take everything back, and props to McLaren.

However, if it really is artificial engine noise played through the speakers, I will have to poop inside an MP4.

 

gents,
we should look into this. pretty interesting stuff.

from a cost perspective, don't u all think it's just a simple system but with a fancy term. i mean seriously, to have an artificial engine sound made to pair with the throttle is a total nonsense, unless again we're talking about cars like Prius or Leaf. it's just much simpler to have activating valves instead of the whole nine yard.

 

funny. my old E60 M5 sounded sick with the Eisenmann Race system. it's just out of the world sounded better than a Ferrari V12. to make it funnier, i kinda had my own manual ISG because i intentionally drove with the rear seats folded down all the time. i can tell u it's quite a bit difference in cabin noise between the rear seat up & down.

 

The McLaren sound induction system is basically the same as the porsche's. There are NO speakers creating fake engine sounds.... like the BMW's.

 

Thanks!!! That's very good to hear. No terrible negrep worthy pun intended.
