What is the difference between the BMW X4 variants?

The BMW X4 is currently offered in Malaysia as a locally assembled (CKD) model in a single variant: the BMW X4 xDrive30i M Sport. For buyers considering the BMW X4, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
