What does the "s" in 3.0si stand for and why does the 4.8i not have it? The outgoing US E53 models were called 3.0i, 4.4i, and 4.8is So why has the 3.0 changed from "i" to "si"?........and why is the new 4.8 still an "i"? Maybe bacause a 4.8si might be confused with the old 4.8is and people may think it's the replacement to the old "is"???
The "s" in 3.0si is not for "Sport" because the Sport package is a separate option and if it were Sport it would have been called "is". So what does the 3.0si have to require an "s" in the model designation?
