Well, if it is a 5.5 Liter engine then it would make sense that each of the twelve cylinders would have a volume of .4583333 Liter.

1. The AMG M275 is a 6.0 liter. not a 5.5L. The title says 'M275 AMG'
2. That does make sense, however I am not looking for swept cylinder volume, I'm looking for combustion chamber volume (in CC)

Should always read the question twice.

I don't know, but you might try contacting Victory Road Performance. They offer cylinder head porting service for the 6.0 M275 as well as upgraded billet turbos, so they very well may have this information.

Sorry, I called Germany a few times but they only seem to speak German. I left a message one time, but even the answering machine spoke German. We'll see if they call me back.
