1. A vehicle comprising:

  • an engine;

    an electric machine;

    a torque converter having an impeller rotatably coupled to the engine, and a turbine;

    a first one-way clutch configured to, responsive toturbine and electric machine speeds being equal, couple the turbine and the electric machine in a first rotational direction to transfer power from the turbine to the electric machine, andthe electric machine speed being greater than turbine speed, isolate the turbine from the electric machine, wherein the first one-way clutch is a selectable one-way clutch that is configured to, responsive to being activated, couple the turbine and the electric machine in the first rotational direction in response to the turbine and the electric machine speeds being equal and isolate the turbine from the electric machine in response to the electric machine speed being greater than turbine speed when activated, and responsive to being deactivated, to isolate the turbine from the electric machine at all the electric machine and the turbine speeds; and

    a second selectable one-way clutch configured to, responsive tobeing activated, couple the turbine and the electric machine in a second direction, that is opposite of the first direction, to transfer power from the electric machine to the turbine, andbeing deactivated, isolate the turbine and the electric machine at all the electric machine and the turbine speeds.
