Awesome to see a little hidden mode like this found, especially considering the car has been out of production for 6 years now. Love the idea that we're not 'done' with the z4m platform
I can't help but think it differs from the M3 mode mentioned, though. My thinking is, why would BMW not enable this feature? I'm going to go with the 'intended for non-M' camp and that BMW did not need to reprogram things but rather deactivate that mode for the M models.
