A vehicle control apparatus to be applied to a hybrid vehicle includes an electric motor, an engine, a clutch mechanism, a torque converter, and a control system. In a case of switching a traveling mode of the hybrid vehicle from a motor mode to an engine mode in response to an increase in requested driving force from a first driving force to a second driving force resulting from an operation of an accelerator of the vehicle, the control system starts up the engine and engages the clutch mechanism while controlling the electric motor based on a transition driving force larger than the first driving force. After a lapse of a delay time from completion of starting up of the engine and engaging the clutch mechanism, the control system controls the electric motor and the engine based on the second driving force larger than the transition driving force.
