Most active noise augmentation systems piggyback off the main speakers - so there's no additional parts needed. Also, there's a negligible amount of energy used in creating a few more sound waves through your existing powered speaker lol. On the other hand, the amount of money saved by not having to design, manufacture, quality control, and assemble another part is utterly massive.

Not the new one coming. It has its own speaker and dedicated module.

Part number 86301AB. It is not currently active in the parts database, but that is the dedicated engine noise speaker.

Devil's advocate, the current BRZ/86 literally has speakers in the same location there that's obviously for the main speakers. We'd need to see the wiring diagram and functional schematic to know for sure.

We looked. It’s a separate module driving a separate speaker box. It’s fed by fuse 28 and hooks into the body control module, presumably to get engine load/rpm over the bus.

Nope.

also check your PMs

Is this implying that removing fuse 28 would disable the fake engine noise, and produce no unintentional electrical side effects? I'm not too good with wiring!

@ mentioned this would work, so maybe he can clarify. I guess we won’t know for sure until someone tries it and documents.

In a case like the one suggested, would not this require the sound generation to be integrated to the main audio system? I ask that because seems like in Japan, you can choose several aftermarket units, which I am not sure how it would integrate.

They should’ve simply skipped this feature, it’s cost and complexity for something silly.

Toyota already developed the unit generally, so perhaps not as big of a deal for them to put it in.

Just give people a no-cost STI muffler option. Problem solved.

Now this is something I could get behind. It's not like the engine is these cars is hard to hear.

What makes you think Toyota developed the sound system? All we've seen on the Toyota test cars is a reskinned Subaru Starlink system.

They put it in Lexus, Avalon's, the GR Yaris... etc.

Most car companies now run the technology in some way, even the porches and BMWs etc. As we all know, modern car engines have become more and more muted by efficiency to the point where its difficult (unless you are open top) to hear a lot, NVH has also gotten a lot better, which in turn dulls down things further.

Turn this car into a track machine and remove all that NVH and/or pull out those restrictive cats and sure, it will sound no different to any car built in the last 30 years with 4 big fat cylinders running to 7500k - bloody good!

NA first drive days for GR86 first week of August
 

That’s not my point though, Toyota did very little engineering and development on this car. It’s not like the first Gen, Subaru already has the Toyota tech like D4S integrated into the car, Toyota was way more hands off until Akio told them to make it ‘different’ very late into development. They probably just rubber stamped Subarus drawings for the active sound control. Integrating their own solution into the Subaru electrics wills be way more effort and not worth it.

Agreed! Can’t wait to hear more aftermarket exhaust clips!
