The parasitic losses on the M3 are exaggerated by those using an app too often, waking up the car and also using third party apps. Based on what I have seen the loads are lower than the newer S. The pack is very efficient and well designed. Of course just like the 12V battery issue on the M3 that never existed there is always something to blow out of proportion. Use of a 12V battery tender on any EV is easy if you hide the cable and the car will not run long charge cycles on the 12V and dramatically reduce losses.
