Have we considered that the 2015 test mule might actually be wearing a Fusion nose and is not the final product? Just saying, if they're using a Fusion frame for testing, why not.
Fusion nose, possibly; frame (actually, unibody), not likely since the Fusion is a front-wheel-drive car.
They're certainly doing a heck of a job keeping a lid on the new design. I can't remember a new model for which this little was known about its final appearance this close to its presumed introduction date.
