I believe that's a Mazdaspeed concept that was shown somewhere in Japan. From comparing the pictures to the ones on Mazda USA's site I see a new front bumper, clear corner lenses, new mirrors, tacked on side skirts, the rims, wing, and a different rear diffuser portion on the bottom of the bumper.

It looks really good although I don't really dig the supports on the wing, they look a bit cheesy.
