Well, if you haven't paid attention, Scott26 had said that the 1M gets the S55 engine (M Division), which will be the basis for the next M3...is that not "unique" enough for you?
Also, this is more than a tune, LSD, ans some aesthetic changes. For the record, all non-M's don't have a LSD, so by your logic, the M3, M5, M6, aren't that much differen from the regular strength models
This car incorporates the M3 suspension, LSD, brakes, and possible other bits. Plus, the chances are S54 will not meet the required specs for emissions, Dr. Segler already had said that the way for M Division is Turbo'd low rev engines...
Now, with this brief, I'm sure that the 1M will not fail to deliver, everytime someone has doubted it, comes more info that it is proving itself, just like these pics, and video.
You may not be impressed, and that is your perogative. But methinks you really are...
