The front fender is, on the X5, made of plastic. And this is one of the things the designer is very proud of on the X5 (like the X6): normally you have a front bumper (plastic), a shutline and then the front fender (metal or plastic like on Renault or an A-Class).

But on the X5, (and X6 it seems)...you have no shutline there because the bumper and the front fender are the same piece!
