Just got M850i loaner....WTF?!

mjr24 · 10-19-2023, 04:51 PM

The exhaust sounds 50 times better than the M8. Major fail on BMW’s part.

ctelimad · 10-19-2023, 05:29 PM

Yes indeed
I had 2 M8s and i can tell you the M850 sounds much better like a proper muscle car!

m3_08 · 10-19-2023, 06:29 PM

wondering if is it a real old fashioned sound or synthesized sound from the speakers

FBMWWINS · 10-19-2023, 06:37 PM

Yes this is ascertained though it would be interesting to know which I-Level (aka I-Step) the mentioned loaner car has. The first M850s (including my former 2019 model) were VERY loud and sounded more like an M8 should sound (or have sounded for that matter). Later as BMW released various updates over the months and years, even the M850ies were "silenced" somewhat and no longer sounded/sound as great as they initially did. So that loaner you got could indeed still be running an "older" I-Level software and thus still produce the nice pops and bangs even in NON-sport settings.

I can guarantee it's not ASD synthesized sound. Even prior to pulling the fuse for ASD when the wife was in the car aka B&W at 20% or less all I did was relish in the true exhaust. Now with ASD defeated via athe fuse it is frankly no different as when I was solo withe the B&W at 50+ plus it drowned out the ASD and I could still hear every burble/gurgle (normal driving) or the pop/bang fire show on a performance drive.

Ah the secret sauce. Sport Individual with transmission on Sport, engine and Sport Plus (which enables the gas guzzling "back fires") and for me with the crappy roads chassis aka suspension in Comfort. The 03/2022 exhaust gate neuter still impacted it no questions asked but the M850i for reasons that boggle my mind still has a hotter stock exhaust.

Blooze, did you pull both fuses or just one? Fuse 218 (ASD) and Fuse 203 (Exhaust flaps - after being open). I can’t stand the thought that I am listening to artificial engine sounds. I truly have no idea what the engine really sounds like.

It's a dealer loaner...so it's a 23 or 24 model.......should be neutered already.

Indeed no secret (to most) but after reading "WTF" in the thread, I wanted to also associate the above to that, which deserves then a double WTF because further silencing the M850i personally upset me a lot back then as it initially sounded like an M car popping and banging as a true M should do. It would be interesting to know in what the 2 exhausts actually differ or if it's only software and calibration. Not sure if the M8 has bigger turbos which could also contribute to muffling the sound somewhat?

I feel like I read somewhere that the M8 sounds being different had to do with the manifold design on that car. I'm not entirely sure if that's correct or not.

That’s exactly why

Get an exhaust with a X pipe that completely changes the tone.
I have a straight piped Awe exhaust on my F90 M5 that’s sounds awesome.

Exactly! I just installed the Dinan X-pipe and MAD secondaries this week on my M8 GC. Super happy with the sound, a little deeper rumble down low and more exotic tones up top. It now sounds how it should have come from the factory.

Yes nice! I agree.

Moopai · 10-29-2023, 12:08 AM

It's real and not synthesized. You also have a feature in the iDrive to set the car to sport mode where the sound of the engine is always loud when you start it even in Comfort mode. I love it... When driving in Sport+, the M850 can turn heads when passing by!

Purposely bought m850 over m8 due to engine sound and suspension compliance, although the 20s on pz4 runflats is still pretty uncomfortable in the 850

Moopai · 10-29-2023, 08:43 AM

Not sure what software updates you’re talking about. My car has the latest update and is loud like hell even when it’s not in Sport+. BMW lately is making a lot to stupid things and making the King (M8) of BMW quiet is beyond stupidity…

Where in the menu is this setting? I’d like to turn it on in my car.

Here you go! Enjoy the great sound every time you start this beast

Thank you! I’ve only had my M850 for a few days and I’m still getting it set up how I like it. This is amazing.

Enjoy it! It's a fun car...
