Sorry, wasn't told that, but I doubt it will be overly expensive.
It is being launched in conjunction with the Automatic Transmission, as the gearbox itself does not have a 'Sport' mode, but will also be available on manual.
It doesn't make a huge difference on the Cooper S, but just enough to make the drive more involved. I would imagine the same difference will be noticeable on the Cooper.
Not that it matters, virtually everyone will have it anyway!
