CT5 AWD system type?

Are there any details?? I have an XTS4 w/HaldexIV, that works great in winter conditions, and if what I read is true, the CTS went from Borg-Warner to a more adaptive Haldex system on the third gen model awd.

Borg Warner 4474 transfer case, same as the CTS, ATS, and the new CT4.
