I'd be willing to be there is a sport mode (faster throttle mapping), DSC but no full/partial hp button. I'd also bet that sport mode is off and DSC is on by default when you fire it up. All of this is based on current "standards". Since the M3 will be more sport and less luxury compared to M5/M6 and because of less power overall I would bet against the full/partial hp button. I sure would like complete memory of settings upon turning off the ignition but doubt it will be that way.
