Abstract
A powertrain includes an electric machine including a rotor defining a hollow center and a fluid-coupling assembly at least partially disposed within the hollow center. The fluid-coupling assembly includes an input shaft, a turbine fixedly coupled to the rotor and having a hub configured to connect with a transmission input shaft, and an impeller configured to fluid couple with the turbine. The impeller is selectively coupled to the rotor and selectively coupled to the input shaft.
