As a vehicle Designer, & Engineer I can tell you for 1000% that they are there for Areo reasons.
They are extensions of the wheel arch liners, and are on every X5 & X6, and most Fords
by guiding air around your "tires" they also have some noise damping affect too (minimal)
as an aero aid they help very slightly towards fuel economy too.
These are wind tunnel tested, and developed.
Having said that, if you were to cut them off, you probably wouldn't notice the difference.
