A motor vehicle has a heat-radiating first component, in particular an exhaust system, and a temperature-sensitive second component disposed adjacently to the heat-radiating first component. At least one heat protection element is disposed between the two components and defines or separates a hot space lying between the first component and the heat protection element from a cold space lying between the second component and the heat protection element. A ventilation device is provided, which, at least when the motor vehicle is being driven, conducts cooling air for cooling the temperature-sensitive second component into the cold space and consequently ensures a constant air exchange in the cold space.
