i doubt it has it
I believe it uses hte normal E92 system
There is a small possibility it will be seen in the facelift models of the E9x, but more likely the first to properly use it ( other than the E70 X5 that uses it for only a ferw systems) would be in the F01 and F10 when they are released.
( Thats the new 7 Series and 5 Series for those that dont know )
