No, "regeneration" is not subject to interpretation except in BMW marketing. I'm only trying to get you to understand what it should mean. In hybrids and electric cars, braking force is resisted by motor-generators that create power from the dissipating the momentum of the car. No way the M3 has any system like this. All BMW is doing is disengaging the alternator during load conditions, which does save energy. The power it is producing under overrun is normally produced in any car. The energy that is saved is the force to drive the alternator along at higher load conditions. I agree it is an efficeincy, but IMO they are stretching the language.
