Any good reason why they did this?
Yes,

The newer f20/21 is a newer model, it's more insulted, more refined, has less NVH and conforms to newer EU legislation.

The M Perfomance division who helped developed the car (Hence the M Badge) felt the interior noise of the engine didn't give the driver enough involvement or feedback.
They decided to go with a high tech sound symposer as they had with the M5.

Blimey so the majority really really dont like. Wonder if BMW actually care or of reading this will take any feedback???

Problem I have is, now I know its there i want NOT to like it. But, when you drive the car, it sounds bloody realistic, addictive and fab

If the M5 and M135 have this, the incoming M3/M4 will surely have it? I think we have to accept it, or keep to the previous gen cars.

My 328i M Sport has "M's" plastered all over it from the factory but it has zero exhaust note inside the cabin. I don't like the idea of synthesized engine/exhaust note but I'd happily take it over the nothing that I hear when I push my car hard.

well being a M135i owner (and numerous BMW ex-owners), I have to say that I hate the idea of producing fake sound from the speakers
I would have prefer how they did on the Z4 3.0 that I owned years ago, a simple sound duct into the cabin
I dont understand why they cant do it again on the newer M cars, despite being Turbocharged and all those, I believe with the right design the sound duct should work. (they might need to ask some speaker manufacturers to get involved since its pretty much the same idea)
for some reason my M135i isnt as loud as I would like both inside and out (unlike most of the owners have claimed, or I could have a faulty unit?), but it does sound fine, the artificial sound works fine indeed
though again I would prefer some real sound

Which majority ?
Ask M135i owners (not just everyone) if they are happy with the sound from their car, with active sound included. I bet more than half will give it thumbs up.

Here we go again with the blow off valves and spoilers or even that cyclonic thingy that connected to the intake .....debate ably pointless conversions that get small gains if any.

Here you go, maybe that sounds amp would make this car faster

Haha, fantastic video!

All reviews I have seen of the car have praised the sound, so my verdict is that BMW has done it right.

I wonder if some of the comments from US forum users would be less negative if they could actually buy these cars.

Exactly. How about we worry about getting good vehicles sold stateside before bitching about the sound they make/don't make?

BMW is full of shit blaming the turbo. If they just made a proper exhaust for the car it would sound fine. I had to upgrade my previous 335 N54 to a bastuck to get it to sound good even with the windows UP!

This is lame.

But if BMW made the car like that, it would be too loud for most buyers (and their neighbours). Modern cars have to be rather silent on the outside.

From the videos i have to say it sounds awesome...what happens if you turn off the stereo?

Next thing you know some VW guy is going to install this and really pimp his ride....will this synthesizer plug into another car or an older 135's stereo?

When you drive at the limit with a helmet on, it is difficult to know the RPM if it is not loud enough. You certainly don't want to start looking at the instrument panel. You can't feel the RPM from a straight six. Maybe from an unbalanced four.

VW guys had it first.

Although it's a simple implementation.

It's not a straight forward install, the symposer takes data from the can bus and works out what to play depending on rpm, throttle position, engine load and vehicle speed.

You know this will really suck if your speakers are blown out. It will just be constant rattling.

I just wish they engineered some engine/exhaust note into the 125i. I will still buy one, but this seems like a glaring omission.

Without meaning to offend anyone am I the only person here who thinks it's actually quite sad?

Why are they trying to make a car sound like something it isn't? As long as it sounds epic with the windows down then I'm happy - Even the Mini Cooper I used to drive sounded good with the windows down and full throttle. I'm test driving the M135i this week so I'm going to keep an open ear for this gizmo and pay careful attention to how the car sounds.

No, it's quite sad.

A tip. Use the minimum throttle while in 3-4 gear. You will hear a distant M-sporty roar where no agressive sound should be whatsoever. The same happens in m5.

If stricter regulations are the reason newer cars are quieter, why then are Lamborghini and Ferrari still allowed to be so loud?
