I'm driving a '24 M440i which is a belt driven 48v, not in the transmission like MY 25 units, but I can say the fuel consumption display is very filtered and delayed in this German made M440 compared to the Mexican made M340i I drove. Both are capable of impressive fuel economy, 50.8 MPG from Cincinnati to Milwaukee averaging 65.5 mph. The shake varies in strength but if in gear like stopped at a light it's barely noticable, in neutral it can be like driving over a magazine in the road. I don't think any changes are needed because anyone really annoyed could code out the stop start. I hope they get more enthusiasts in their focus groups of iD9 because that is where improvements are to be made. And if the economy numbers weren't impressive enough that was with the staggered Goodyear AS3 summer 18" run flats.
