1. A hybrid electric vehicle (HEV), comprising:
a front driveline configured to drive front wheels;
a rear driveline configured to drive rear wheels;
an electrically variable transmission (EVT) including a power splitting gear set having an input member, a carrier coupled for rotation with the input member, a sun gear coupled for rotation with a connecting member, an annulus gear, and a plurality of pinion gears;
a transfer gear arrangement including an input gear in meshing engagement with the annulus gear, and an output gear connected for common rotation with the input gear and in meshing engagement with a final drive to provide drive torque thereto;
an internal combustion engine selectively connected to the input member of the EVT to provide drive torque to the front driveline;
a brake clutch coupled to the input member between the engine and the carrier;
a selectable one way clutch (SOWC) coupled to the input member between the engine and the carrier;
a first electric machine coupled to the EVT via the connecting member to selectively provide drive torque to the front driveline;
a second electric machine configured to selectively provide drive torque to the rear driveline; and
a battery electrically coupled to the first and second electric machines for powering thereof,
wherein the vehicle is absent of a P3 motor,
wherein the internal combustion engine, the EVT, and the first and second electric machines are configured to provide the HEV with four-wheel drive or all-wheel drive capability.
