Hi all
I've just moved from an F31 330d to F11 530d and noticed that the engine in the new F11 sound much nicer under acceleration than in my F31. It even sounds better just moving about at parking speeds! Sounds more traditionally like a large capacity straight six.
Why is this, exhaust tuning differences or something to do with the sound insulation properties? To be honest I always like the sound in my 330d but it doesn't compare to the same engine type in the F11.
Thoughts
