There's been many very valid suggestions as to why the M5 will have a _different_ output curve compared to the X6M (even though the two share the same engine). But another reason I can think of is the mpg.
I'm pretty sure they can't squeeze 10/10 out of it when the engine is in the X6M probably because the mpg would be quite, quite crazy. With the M5 being potentially quite a bit lighter, they can really go to town with it.
I know people don't buy these cars to save the pandas or whatever, but in these days and age, single figures or low tens would cause comment.
