1. A power transfer apparatus for transferring drive torque from a vehicular drivetrain to first and second drivelines, comprising:

  • a first input shaft rotatably driven by the drivetrain about a first rotary axis;

    a second input shaft supported for rotation about a second rotary axis that is angled relative to said first rotary axis;

    a constant velocity universal joint interconnecting said second input shaft for rotation with said first input shaft;

    first and second output shafts respectively interconnected to the first and second drivelines, at least one of said first and second output shafts being supported for rotation about a third rotary axis that is offset from said second rotary axis;

    an interaxle differential interconnecting said first and second output shafts for permitting speed differentiation therebetween so as to establish a Full-Time four-wheel drive mode; and

    a torque transfer mechanism interconnecting said interaxle differential to said second input member for transferring drive torque to said first and second output shafts.
