Are you sure it's black chrome and not just an optical illusion caused by the lighting? I can't find any mention of a black chrome option at the Escape website or Ford Media (not that I'd want to; I never liked the chrome on the bumper).
I don't doubt that there are occasional errors or omissions in information at Ford's websites. For example, since 2005 the minisite for the Mustang has listed the GT's engine as a 4.6L OHV V8 in its specifications section. In spite of things like that, I would still want to see an option in writing rather than just determining its presence on the basis of a picture.It wouldnt be the first time that Ford forgot to mention an option on a website.
