There will be no special M engines ever again. They are all going to be closer to series derivatives like S63 and S55 are. You won't see S54, S65, or S85 again. Maybe that's a good thing because M GmbH messed up on bearing design on all 3 of those engines and they fail at rates unheard of for N engines.

However, they are still undoubtedly better than the N series engines.
