Abstract
A motor vehicle can be powered by a combustion engine or an electric machine or both. Coolant is conveyed in the coolant circuit first to the electric machine before being conveyed from the electric machine to the combustion engine for cooling both the combustion engine and the electric machine. A cooling device adjusts a temperature of the coolant in the coolant circuit in such a way that the cooling device adjusts the coolant to a first temperature, when the motor vehicle is powered by the combustion engine, and to a second temperature which is less than the first temperature, when the motor vehicle is powered by the electric machine and the combustion engine.
