A ratio calculation section calculates an EV/HV travel ratio, and a display section displays the EV/HV ratio as a percentage. In this way it is possible to easily recognize the EV/HV travel ratio. ## Claims ### Claim 1 A hybrid vehicle fitted with both a motor and an engine, comprising mode control means for performing control so as to carry out an EV mode for traveling using output of the motor with the engine stopped, and an HV mode for appropriately driving the engine according to travel conditions and traveling using output of the motor and the engine; and mode specific travel distance display means for displaying travel distance in EV mode and travel distance in HV mode as percentages. ### Claim 2 (depends on 1) The hybrid vehicle of claim 1, wherein: percentages for travel distance in EV mode and travel distance in HV mode in two different time periods are displayed. ### Claim 3 (depends on 2) The hybrid vehicle of claim 2, wherein: the two different time periods are periods in which the same route is travelled, and the two periods do not overlap with each other. ### Claim 4 (depends on 2) The hybrid vehicle of claim 2, wherein: the two different time periods are periods of the same length, and the two periods do not overlap with each other. ### Claim 5 (depends on 2) The hybrid vehicle of claim 2, wherein: the two different time periods are periods of different length, and include a period where the two periods overlap with each other. ### Claim 6 (depends on 2) The hybrid vehicle of claim 2, wherein it is possible to charge a battery for supplying power to the motor from an eternal power source, and a charging fee or a charging power amount for the two different time periods are displayed. ### Claim 7 (depends on 3) The hybrid vehicle of claim 3, wherein it is possible to charge a battery for supplying power to the motor from an eternal power source, and a charging fee or a charging power amount for the two different time periods are displayed. ### Claim 8 (depends on 4) The hybrid vehicle of claim 4, wherein it is possible to charge a battery for supplying power to the motor from an eternal power source, and a charging fee or a charging power amount for the two different time periods are displayed. ### Claim 9 (depends on 5) The hybrid vehicle of claim 5, wherein it is possible to charge a battery for supplying power to the motor from an eternal power source, and a charging fee or a charging power amount for the two different time periods are displayed.
