Volvo uses the Haldex awd system anyway. It's one of those electronic fwd-until-the-fronts-slip systems so it's not really as much of an aid to the handling as one might expect. Unless of course the control over the Haldex diff has somehow been integrated into the 4C system and it does continuously apportion torque between front and rear, but yeah I don't think that's been done.

Awd VWs and Audis based on the A-platform use the Haldex also. It's not so good. B-platform ones however use a real Torsen center diff.
