No theres no Sport button on a Non Sport.
But on a SPORT, I wanted to know what it does ??
I think if you were to switch it off on a sport it would drive like a non sport and less stiffened setup, and if switched on it will be opposite.
Which means best of both worlds at the push of a button....am I on the right lines????

Or ...how about a NON SPORT with ADAPTIVE??

Sorry for so many options but just trying to decide before spending $70k+ on an X5 !
