BER
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.

I understand what it does. Would you rather me call it by a name that noones knows and isn't identified in BMW literature?

If you understood this you would not be wondering if the M3 has a special battery. Peace!

I guess I will spoonfeed you the required info. I just proved to you why I would be looking for a special battery and you still won't relent. Quote:

@Tbone From what I have read, it looks like the 1-series also get BER. So if they have the same battery and it is larger than normal, then that is one clue that the models might come with BER.

One more shot at this, then I'm going to bed. In most every car, the alternator spins happily away producing power all the time and keeping the battery topped off. What BMW is doing now is only engaging the alternator when the propulsion power required of the engine is low. Is this somehow newfound energy? No. Every car produces electrical power under these conditions. The efficient part is that an alternator load is not added to the propulsive load. So, the alternator is only making power part of the time, requiring a larger battery that can carry the car theough the periods when power isn't being generated and stand more frequent off/on charging. Is this efficient? YES. Is this regeneration? Absolutely NOT. I wonder if you are cruising for hours on a level freeway if the alternator eventually cuts in--seems like it would have to. I understand now your battery fixation. I don't understand BMW's stretching the facts.

You seem to be fixated on this aspect. I have never led on that I believe it to be anything other than what BMW has stated. I have discussed this in other threads in the past as well. I have told you I understand BMW's implementation. There is nothing else I can do if you, for some reason, fail to acknowledge that.

Tbone, would you say the battery was roughly 13in x 6in x 7in (length x width x height)? If you can recall.
I gotta say, looking at the second hi-rez pic, it looks like the battery could indeed be 1ft+.

The battery in the M3 was in the sedan so you should be able to approximate the size that way. Unfortunately, I didn't take photograph a part of my body where I could have showed you how a foot-long was. On the 1 series, the battery took up the entire lower part of the trunk.

I apologize if this was discussed already, but the reflectors are *definitely* stick-on?

I think pictures from the NA show has shown that it is definitely NOT stick-on and rather has an indentation in the bumper itself that fits the size of the reflectors. Being that I ordered an AW I'm hoping I can find a white reflector to replace it and hope that's enough to hide it.
