What is so fancy with current front and rear difs? They are not active like they used to be in 2006 or so.

Anyway what I do hope and what likely was the goal is that the reduction of "setting possibilities" reduces the benefit of using tons of money on testing (simply because there is less settings to test)
As this likely is the area that caused large part of the gap between MSport and Hyundai/Toyota lately.
The current front and rear differentials , have the ability to change positive preload and negative preload , normal by nitrogen gas inserted it a piston chamber , during service you can open a bung insert a needle connected to a gas bottle and adjust the pressure to change the setting

When it used to be mechanically adjusted by a thread system with temperature change it change preload , and in some cases if a low setting was chosen it would wind off in time , the gas system is more consistent , also adding adjustment of negative preload added another dimension of adjustment esp on the front diff to aid turn in

This was first used in the polo in 2014 and Citroen ds3 , msport first used in 2015 car
