Looking at the power curves,weight and updated tech. I don't question that the S55 and the new car is significantly faster in pretty much all measures. This include track times in the hands of professional drivers, personally though I'm less sure that it will be much faster on a track when driven by amateurs. With DSC off the long, linear, responsive and predictable power band of the S65 makes for a car that is very easy to drive fast on a track, I suspect the S55 will be more of a challenge at 10/10s as RWD turbo cars often are but we'll see, BMW say they worked magic with responsiveness and lag elimination.
