I don't see the same ratings that you're finding. Here's the ratings I see listed currently. Don't look bad to me, though the score of 80 isn't as good as the Lexus (88). I test drove both and would NEVER purchase the Lexus (though I understand why ladies like it).
Oddly enough, I didn't see the 2012 X3 3.5i listed, only the 2.8i (even though the graphic clearly shows 6-cyl. turbo).
