The architecture of the FLEX4 system consists of a power take-off unit (PTU) with a Magna-patented disconnect system in the front axle and couplings on the rear axle with twin dog clutches.
The small package space is achieved by a number of innovative design features including a new hydraulic vane-type pump, which also contributes to improved efficiency, two patented dog clutches replacing bulkier conventional clutch packs, and an Intelligently Nested gear set.

And speaking of connecting and disconnecting via a clutch, they've developed an all-wheel-drive (AWD) disconnect clutch that consists of a hydraulically operated synchronizer clutch that's integrated on the input shaft on the power take-off unit (PTU) and electrically operated dog clutches on the rear axle.
Dog clutches can now be modeled with rectangular dogs and negative undercut angle.
