to 3) ... to the time the OP started this thread, the information were that the M-GmbH had made an descision towards the S55 based on the N55 ... now it seems so that they had changed this descision towards an engine concept they had patented last year
... and it could be that this engine would be an totally new developed one and not based on an existing BMW AG engine!
Also it could be that the M-GmbH drops the costly TriTurbo-Concept and chose an simplier BiTurbo FI system if this also fulfil the performence needs.
In reply to your first point, I direct you to Paragraph 3, line 1 of the original post.
