I am relatively new to Ferrari ownership (6 years ago). I own a 575, which has a similar (less powerful) Tipo 133 engine to a 612. I have driven 599s, and remember vividly when the model came out the media buzz about the "Enzo engine". I thought the 599s engine was amazing, responsive, so easy to rev, enormously powerful. It was made out to be in a different league to the 575/612 engine. My question here is, are there owners of both who would like to give their opinions? Is the newer engine far better in every way? Or does the 133 have any qualities that persist beyond the 140? I guess two analogies might be: The last V12 engine change: 550 had more hp than F512M but arguably less character, and mid range punch. All new 4.3 engine in the 430 had more torque and power than 360's, but 360 apparently had more racing character (valves etc). What do people think with experience of both V12s?
