I'll be glad this feature made it but am also suprised by its lack of mention in US information like the brochures. Perhaps they know most Americans and most that will buy the M3 don't give a squat about mpg. Thanks for the work on this one!

1er has been abroad for some time. I believe this is a model refresh with the new 1er models, not so much a "mid-life" change.
Again, I have nothing conrete on NA 1er BER, but press release have indicated the 1er will have BER.
I also read an older article that said the BER/AGM batteries were black and the standard batteries were white. Not sure if this still holds true, however, you can see the M3 has a black battery, same as the Euro one. It is the 1er that has the white battery

White battery is the 1er.

BER also uses a special alternator as well.
Also, BER doesn't indicate a performance compromise. It is the other way around. It actually reduces the load on the engine so more energy can be applied for moving the car.
