It's annoying that they don't, the ZF vector drive system should at least be an option instead of forcing you to get an X5M if you want it, hopefully that will be rectified with the F15. They have a system that's better then Acura's current SH-AWD since it works off throttle but they keep it to the M and the "sporty" X6.
