I don't believe this is Haldex XWD, but it does appear to offer complete transferring of power in either direction. According to some of the press it's a system that in normal situations is 50/50 which isn't the same as normal in the A3 and TT which place almost all the power to the front wheels and constantly shuffle power as called for but can never fully shift more than 50% to the rear.
I have yet to hear or see data stating it's got a rear electronic diff which would make it Haldex XWD, so until Qisha can confirm this I don't think it is.
