Added a bit there.
Since the NV125 is fixed at 68R/32F, the power cannot drive all/100% of the provided TQ to any half shaft. It will only drive up to what is available to either axle as distributed by the NV125.
This is different with XDrive in later models with the clutched ATC500. It can move something close to (or maybe all the way up to) 100% of the engines TQ to either the front or real axle.
