An engine starting control system for hybrid vehicles is provided to prevent a temporal drop in drive force when starting an engine. The control system maintains an operating mode of a switching mechanism when starting the engine by the first motor, in a case that the vehicle is propelled in the forward direction by the first motor and that the switching mechanism is in a second mode, or in a case that the vehicle is propelled in the reverse direction by the first motor and that the switching mechanism is in the first mode. Thereafter, the control system increases a rotational speed of the engine to a self-sustaining speed, switches the operating mode of the switching mechanism, and increases torque of the engine.
