A new series of spyshots has been released showing the 2013 BMW F12 M6 Convertible once again in its camouflaged dress. The BMW F13 M6 Cabrio is expected to be revealed in September 2012, ahead of the 2012 Paris Motor Show. The 2013 M6 is expected to share the same engine as the new F10 M5, the turbocharged eight-cylinder powerplant from the X5 and X6 M.
This M6 prototype is sporting the production M6 bumper underneath heavy front signature BMW camouflage. Other typical M features seen here are the quad exhausts and massive front brakes.
