A hybrid power drive system includes an engine, a first motor, a first clutch operatively coupled between the engine and the first motor, a first decelerating mechanism having an input portion operatively coupled between the first clutch and the first motor, where the input portion is configured to receive rotational power from the first motor and/or the engine. The first decelerating mechanism has an output portion operative to drive at least one first wheel, and a second motor is operatively coupled to at least one second wheel through a second decelerating mechanism. An energy storage device is coupled separately to the first motor and to the second motor. The engine, the first clutch and the first motor are connected in sequence, and the second decelerating mechanism and the at least one second wheel are connected in sequence. Various combinations of operating modes are provided to meet energy efficiency requirements and user power demands.
