A method for operating a motor vehicle having at least one electric drive component which is cooled via at least one coolant circuit which is coupled thermally to a refrigerant circuit. In a first operating mode of the motor vehicle, an inlet temperature of a coolant of the at least one coolant circuit is set to a first value by active cooling by means of the refrigerant circuit. In a second operating mode, in particular a sports operating mode of the motor vehicle, the inlet temperature is lowered with respect to the first operating mode. As a result, more pronounced cooling of the components is made possible in the second operating mode, as a result of which the maximum driving power of the motor vehicle is increased.

1. A method of operating a motor vehicle with at least one electric drive component, which is cooled via at least one coolant circuit that is thermally coupled to a refrigerant circuit, the method comprising: allowing a driver of the motor vehicle to select via a control element between a first operating mode designed as a normal operating mode and a second operating mode designed as a sports operating mode,in the first operating mode of the motor vehicle, setting a flow temperature of a coolant of the at least one coolant circuit to a first value through active cooling with the refrigerant circuit, andin the second operation mode of the motor vehicle, setting the flow temperature of the coolant of the at least one coolant circuit to a second, smaller value through active cooling with the refrigerant circuit. 2. The method of claim 1, wherein respective flow temperatures are set in at least two cooling circuits with the refrigerant circuit. 3. The method of claim 2, wherein the respective flow temperatures of the at least two coolant circuits are different from each other. 4. The method of claim 1, wherein the at least one coolant circuit is used solely for cooling a high-voltage battery of the motor vehicle. 5. The method of claim 1, wherein an additional coolant circuit is used for cooling at least one of power electronics, a DC-DC converter, a battery charger, an electric drive unit, and a transmission. 6. The method of claim 1, wherein in the second operating mode, the maximum cooling power of the refrigerant circuit is used for decreasing a flow temperature of the at least one coolant circuit. 7. The method of claim 1, wherein in the at least one coolant circuit, a total volume flow of coolant is divided into at least two partial volume flows, which are each used to cool different drive components. 8. The method of claim 7, wherein a flow ratio between the at least two partial volume flows is adjusted differently commensurate with the two operating modes. 9. A motor vehicle, comprising: a control element allowing a driver to select between a first operating mode and a second operating mode, wherein the motor vehicle is configured to carry out a method of operating a motor vehicle with at least one electric drive component, which is cooled via at least one coolant circuit that is thermally coupled to a refrigerant circuit, by: allowing a driver of the motor vehicle to select via a control element between the first operating mode designed as a normal operating mode and the second operating mode designed as a sports operating mode,in response to selection of the first operating mode of the motor vehicle, setting a flow temperature of a coolant of the at least one coolant circuit to a first value through active cooling with the refrigerant circuit, andin response to selection of the second operation mode of the motor vehicle, setting the flow temperature of the coolant of the at least one coolant circuit to a second, smaller value through active cooling with the refrigerant circuit.
