Thanks for the insight. I’m confused though — aren’t emissions and fuel efficiency proportional (everything else being equal of course)? The emissions come from the combusting of fuel — If I’m combusting fuel, I’m releasing emissions. If I’m not combusting fuel, I’m not releasing emissions. They should go hand in hand, and roughly proportional to each other (I understand that starting takes more fuel than idling so of course there is some efficiency loss in re-starting over idling for some threshold time).There is no fuel efficiency gained from the auto stop. It’s about emissions standards. In fact you may lose some fuel efficiency from the starting procedure.
So, with A.S.S off: if I’m not moving but combusting fuel and going nowhere, by definition my fuel efficiency is decreasing (and my emissions are increasing). What I wonder is whether the financial and (production & shipping) energy costs of battery and starter wear outweigh the financial and energy savings from the A.S.S.
