The problem with the M3 at Detroit is that there is no reason to believe that car was a fully US spec vehicle. Indeed we've seen many examples of cars since then that don't have US spec seats and/or reflectors (not to mention constant confusion about the 18" wheels). Additionally you can adopt AGM without implementing BER and it might make sense to use the same battery everywhere. AGM charge considerations are different from normal batteries, so using the same battery would allow the use of the same battery charger/management module as well. I'm not sure we will know for sure on the 8th - I suspect the acid test will be what TIS says.
