I don't know if anyone here has really been able to define what the "S" means, I wonder if there is a member here from BMWNA or another official BMW location that can really define the "S".

My thought is BMW wanted to create an identity for the 4.6 and 4.8 that would truly stand apart from the 4.4i so they just added the "S" without any significant meaning.
