A hybrid driveline which may be operated in a hydrostatic drive mode and a direct drive mode and a method of operating a hybrid driveline in a hydrostatic drive mode and a direct drive mode is provided. The hybrid driveline comprises a power source, a first hydrostatic unit drivingly engaged with the power source, a second hydrostatic unit selectively drivingly engaged with a vehicle output and in fluid communication with the first hydrostatic unit, an accumulator assembly in fluid communication with the first hydrostatic unit and the second hydrostatic unit, and a clutching device selectively drivingly engaged with the vehicle output and one of the first hydrostatic unit and the second hydrostatic unit. The hybrid driveline provides the benefits of a series hybrid arrangement and a parallel hybrid arrangement, reduces torque interruptions during operation and shifting procedures, and increases an efficiency of a vehicle the driveline is incorporated in.
