1. A hybrid vehicle comprising:

  • an internal combustion engine;

    an electric motor;

    an inverter that drives the electric motor;

    a compartment portion that houses the internal combustion engine, the electric motor, and the inverter in a front portion of the vehicle;

    an internal combustion engine radiator which is arranged near the front-most portion of the compartment portion and in substantially a center in the vehicle width direction, and which performs heat exchange between coolant that cools the internal combustion engine and outside air;

    an internal combustion engine radiator conduit through which the coolant that cools the internal combustion engine flows and which is arranged behind the internal combustion engine radiator, the internal combustion engine radiator conduit being attached to the internal combustion engine radiator;

    a bumper that is arranged at the front side of the vehicle;

    a reinforcement which is mounted to front ends of left and right side members that are disposed at left and right sides of the vehicle and are able to absorb energy from force applied from ahead, wherein the reinforcement has a structure which is capable of dispersing the force applied from ahead of the vehicle and transferring the force applied from ahead of the vehicle, to the left and right side members, and which extends in the vehicle width direction behind the bumper;

    an electric motor radiator which is arranged behind the reinforcement and in front of the internal combustion engine radiator in the vehicle, and which performs heat exchange between coolant that cools the electric motor and the inverter, and outside air; and

    an electric motor radiator conduit through which the coolant that has circulated through the electric motor and the inverter flows and which is arranged above the reinforcement and in front of the electric motor radiator, the electric motor radiator conduit being attached to the electric motor radiator.
