Abstract

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.
