I think that what the 1M did was to define the real meaning of what a "tuned series engine" really is from the point of view of corporate cost reduction. Other than the overboost feature the sucker was exactly like the series engine. Exactly. In other words, the end of what ///M used to do.

Every other ///M engine went thru much more significant and invasive variations of series engines, not just "tuned". Like displacement changes, block changes, individual throttles, even cylinder count.

With that said, now more than ever an M5/M6 is a tuned 550i/650i, the X5M/X6M is a tuned X5/X6 and finally a M3/M4 is a tuned 335i/435i.

Try to even fathom saying that of a past M3 and M5 and you will know what I am talking about.

Like I said before, I will get an F80 M3. Without doubt this will perform better than any M3 before. But that does not mean that I do not know that I am getting less than what I used to get in an ///M. The value, that intangible thing that will kill car models sooner of later, is just not there anymore. You can see value in the new Corvette, in the new Mustang, even in the upcoming C63.

In this one, not as much as before.

A 1M has a tuned series engine. The F8x uses the S55, derived from the N55. Just like the S50/S52/S54 I6 in past M3s are derived from series engines, but completely reengineered.
