A hybrid electric vehicle includes an engine that can selectively provide drive torque to propel the vehicle. An electric machine also selectively provides drive torque. A differential transfers the torque to and amongst wheels. A planetary gearset is coupled to the engine and has a ring-gear for transmitting ring-gear-torque to the differential. A continuous torque transfer member operatively couples the ring-gear and the electric machine to the differential. At least one controller is configured to alter engine output based on a ring-gear-torque-threshold. This enables a desired torque to transfer through the continuous torque transfer member to the differential.
