Abstract: A transmission includes a single planetary gearset, a first torque machine, an output member and a two-speed gearset that is coupled to the drive member. The single planetary gearset includes a sun gear, a carrier gearset and a ring gear, wherein the carrier gearset is rotatably couplable to the input member and rotatably couplable to the output member, the sun gear is rotatably coupled to a rotor of the first torque machine, and the ring gear is rotatably couplable to the input member and rotatably couplable to the output member. The output member is rotatably couplable to the two-speed gearset, which is configured to operate in one of a first gear ratio and a second gear ratio.
