Hi all I removed the HVAC panel to send off for "destickying" and found this behind it What does it mean? I can only assume I have a rare "EVO" model Image Unavailable, Please Login
550 = F133 & 575 = F133M - M = Modificato which is close enough in meaning to Evoluzione for a contractor's internal hand-written sticker
It is somebody's interpretation of the Type F133E engine you have in your 575M. The E may not stand for Evoluzione (Or maybe it does, who knows with Ferrari?), but is just the version of the engine in the F133A (550), F133E (575M), F133F (7.1.1 612), F133G (Superamerica), F133H (7.3.2 612) series of 5748 cc, 65 degree V12 engines. Ferrari did skip the F133B-D engine types, unless the were experimental and never reached production, so maybe the E really was for Evoluzione. Lots of changes from the 550 engine to the 575M engine.
