PROBLEM TO BE SOLVED: To provide a hybrid vehicle operating method. SOLUTION: A drive train for a vehicle having front and rear wheels includes one fluidic motor 4, and one pump interconnected in a continuous loop, with one conduit connected to the inlet of the fluidic motor 4 to the outlet of the pump and a second conduit connecting the inlet of the pump to the outlet of the fluidic motor. A gas/liquid fluid accumulator is in fluid communication with the first conduit, and a low pressure reservoir is in fluid communication with the second conduit. An engine is employed to drive the pump. Sensors are included for detecting the pressure within the accumulator 6, the power demanded of the vehicle by the driver, and, optionally, vehicle speed. A motor controller 22 controls displacement of the fluidic motor 4 in response to the sensed power demand, and a pump controller 20 controls displacement of the pump responsive to the signal for detected pressure.
