Guys,
Which V12 has a "Active Cylinder Control (ACC)" or anything similar to that, I have done some reading and everything says that it stopped at 2001, is that true?

I believe Mercedes called it ZAS and it was only on the non-TT V12s as standard and an option on the V8s, at least this was the case in Europe.
However, I struggle to see how my TT 600 routinely gets 24mpg (US gallon) on highway driving without it!

It was indeed that the pre-facelift (1999-2002) V12 W220 S-Classes had ACC. Facelift models did not.
