A vehicle has an electric heating device which in operation reaches a temperature of more than 50° C., and includes a flat perforated decorative layer which is disposed on a front face of the heating device. Because of the perforation of the decorative layer, the heating device can radiate infrared radiation through holes provided in the decorative layer directly into a passenger compartment of the vehicle. The vehicle also has a reflector layer which is disposed on a rear face of the heating device facing away from the front face and is provided in order to reflect infrared radiation emitted by the heating device in the direction of the passenger compartment.
