Unfortunately I can't post a link because it is a screen shot from the BMW TIS site. You'd have to purchase a subscription. I cropped the top of the page that has info that can't be posted online.
You can see at the very top of the info for the M550...that the link is specifically from the G30 M550 info. I also verified several other more modern BMWs (a g12 7 series, an f15 X5 and an f06 650ix GC)...and both of those models data also said it was 50/50.
It was only when I went back to the earlier 1st gen models that had xDrive that the data mentions the 40/60 torque split. Again, xDrive debuted on the LCI e53 X5 and also on the e83 (not sure what year on that model).
And if my memory serves correct...the 1st X5s that were built from 1999 to 2004...they had a special AWD system that was a combination of the AWD systems used in the 1980s on the e30 3 series & e34 5 series...but now included DSC...I believe it was referred to "in house" as
DSC-X and they may have had a 48/52 (front/rear) torque split.
If you have access to the BMW TIS or other BMW technical documents...do a search for ALL WHEEL DRIVE SYSTEM xDRIVE w/TRANSFER BOX to see what you find
And do keep in mind which transfer box is being discussed. I say that because some of the smaller BMWs with xDrive that share technology with MINI...they may have a different torque split due to some of those models being FWD biased.
