If one has an MPE what would be the loudest configuration Sport+ and Track Mode (exhaust)? Or would it be this "hidden" mode i.e. Comfort + MDM (Traction) plus Track Mode (Exhaust)? All this configuring has me confused and doesn't exactly line up with the M2's reputation of being a more analog back to basics machine.

You can see all exhaust modes in technical training manual pdf, downloadable in the sticky documents thread of M2 discussion.
The OEM exhaust has flaps.
AFAIK you have 3 different settings regarding those flaps/noise:
-sport/sport + = loud, some pops and gurglea
-comfort = more quiet; almost no pops and gurgles
-traction mode = loud with exaggerated pops if DCT is in sequential mode
Traction mode in D sounds like comfort.
Traction is a mode by itself - you can access it pressing once DSC, whether you are in comfort or sport mode. It is a mode by itself with similar settings to confort in steering, accelerator response, etc. All details in the pdf of technical training. |
Thanks for this. I'll review that document. One last question; does Sport+ engage "Traction MDM" mode or is this always a separate individual function? If you have to engage it separately when in Sport+ do you still get the loudness of Sport+ and also the extra pops and gurgles of the Traction mode?
