    • F80 M3 / F82 M4 testing at the ring shows off the new S55 turbo inline-6 exhaust note - New M3/M4 sounds average? Comparison to E92 M3 S65 V8

      It is no secret the switch to turbo motors for the BMW M division has brought along with it some issues that upset M purists. A recent comparison between the classic naturally aspirated M exhaust note in the E60 M5 versus the new turbo exhaust note in the F10 M5 highlighted a glaring difference in sound quality. Do not forget, the F10 M5 is receiving a revised exhaust system so BMW themselves recognizes the exhaust note in their latest M cars has not exactly been up to the standards they set themselves.


      Let's be honest, the new M5 even fakes its exhaust sound with synthetic noise piped into the cabin so things have gone a bit off the rails at M. BMW recognizes its latest M missteps so this should bode well for the exhaust note of the new F80 M3 and F82 M4. The video below is the clearest sound yet of the upcoming new M cars.

      Take a listen:


      How do you feel? It seems to be a bit more uncorked than the F10 M5 factory note was but still has a low pitched drone sound quality to it. Spectacular? No. Passable? Sure.

      Now take a listen to a compilation of the E92 M3 S65 V8 exhaust note:


      Is it even a contest? If fuel economy and cost saving matters more than emotion at M these days, so be it. But something has been lost in translation.

        Not suprisingly no. In your mind it might be, but what you think and what is fact is way different, and that was made clear awhile ago.

        Can't agree to the facts? You are wrong and can't agree for whatever reason. Here's another chance to sack up and be a man. To use your words.

        Funny how you put together facts in a skewed way. It's comical really. Keep going. You said you were done but it's clear you arn't. I'm waiting for some more of your posts to laugh at. Maybe you will give yourself a mental disability at the end of it all.

        YOU LITERALLY JUST SAID THAT.

        Holy crap man.

        I normally would be laughing at you for all your posts page after page alluding to the sound of the Maserati motor being better because the Ferrari sounds better without ever realizing it's the Ferrari's crank that gives it that great sound quality but now it's just kind of sad. I'm starting to feel sorry for you.

        I suppose that's as close as you'll get to simply saying you were wrong.

        When you have time let me know how you're right. If key members from OJ's legal team were still alive I would have advised contacting them to help...

        3:08...is that a BOV or BPV that I hear making a screeching noise?

        the exhaust note sounds boring, but the engine note sounds like a great i-6. Im sure the exhaust note will have a "fruitier" sound when downpipes eliminating the main cats become available Click here to enlarge

        the current n55 is rated at 33mpg on the highway on the F30, i dont expect this s55 to stray too far from that. if this thing makes 450 underrated hp and gets 27-28 mpg on the highway, thats forward progress no matter how u slice it

        Great post and I am in agreement if the S55 in-fact delivers similarly.

        WOW I never thought that the M3/M4 would sound so good on paper! Ditch the E90 M3 Sedan issues due to rod bearing issues and jump straight to M3?
