Both our cars have it ( 2011 M3 and 2013 Cayenne ) but both are set to permanently off since neither of us like the sensation of the engine shutting off and on.
Never measured the mpg but have been meaning to out of sheer curiosity. I doubt it's a huge difference; maybe just enough to give BMW their mpg numbers for advertisement.

I didn't know M series BMWs had ASS; my X5M doesn't have it so I figured it wouldn't even be an option on any M's???
