This spy shot was sent in to us by an anonymous tipster, who caught what appears to be an extended-wheelbase Ford Fusion Hybrid. But it’s not just stretched: those wheel arches are definitely not stock Fusion kit, which suggests that the Fusion Hybrid body might just be a mule body concealing an unrelated chassis under development. Can you spot any other clues that might hint at what we’re looking at? Got a guess? Let us know in the comments. [Thanks to you know who you are!]
