Thats exactly what I was thinking.......
How the hell is a D mode shifting faster than S4, is BMW truly slowing down the shift so that the "surge" is not "slurred" through a quick and smooth shift? With the extra 1.2mph in speed you get from the "surge" if they could take that and the shift times of the D3 mode, isn't that the idea situation? How is S4 so much slower in the shift and how can that be good for performance?
Sorry if I sound ignorant......
