One of the interesting aspects of A0B is it has changed the baseline, ZVW30 configuration. Regardless of whether one chooses to get the upgrade or not, having A0B is the new baseline. This is why it is important to ask if any 'problem' user mileage is pre or post SSC-A0B or manufactured after January 2010. Now there has been a lot of speculation, little data, about regeneration and its effect on mileage. I know from my NHW11 studies that avoiding regeneration is better than trying to maximize regeneration when stopping. Paper analysis of energy flow supports this claim. But we have little, hard engineering data (that I'm aware of). I just don't see any hard, engineering data that shows SSC-A0B impacts mileage ... yet. Bob Wilson
