    • What the S63tu twin turbo V8 in the new F10 M5 sounds like

      BMWUK has put out a great new video showing off the engine sounds of the new F10 M5. The motor sounds great which makes us wonder why BMW has to go the cheesy fake engine note route when the motor is more than capable of speaking for itself. The S63tu sounds a bit more aggressive than the standard S63 twin turbo V8 that is in the X5/X6 M likely due to its intake, exhaust, and rev limit changes. Check out the video below.

        Its because BMW wanted a more controled in cabin enviornment. Another quest to please the customer. Quiet on the inside unless you want noise. The video is ehh. Some test drive vids have better sound bites. On another note, I like the sound of an open m30.

        I don't see why we could not have an exhaust cutout which makes far more sense than a fake engine noise. Porsche has it down...

        when I test drove the F10 M5 the engineer told me that 560hp is calculated at a IAT 60C so if you have anything under that you will make more then 560HP for sure!IAT 60C is very hot!

        Interesting... sounds like the power will be pretty adjustable based on conditions which is kind of just like the N54.

        Cut outs are for external noise control. The external noise of the m5 is not the problem. When a cabin is somewhat sound proof cut outs are not the answer to getting some of that noise inside. Making the exhaust so loud to enjoy inside the car would be obnoxious so fake speaker noise is utalized.

        Yes, but this noise also translates to the cabin.

        Obnoxiously loud exhaust worked for me and my car...

        I don't think it would basically need straight pipes. Every other manufacturer manages to convey the natural engine noise into the cabin. Genius engineers at BMW can't? The best solution they could come up with was synthetic engine sound? BS.

        Not exactly. BMW wants to keep the noise out of the cabin. That is the difference.

        Yes but at least in the Z4 they would pipe in the REAL engine sounds. Why they couldn't do that again and went the synthetic route I have no clue.
