ABSTRACT:
A motor vehicle, for example an electric vehicle, of the kind having a propulsion motor with a low heat loss, i.e. which emits heat at a relatively low rate, has a heating and ventilating apparatus for its cabin. The heating and ventilating apparatus comprises: first heating and ventilating means including a first blower feeding air into a first duct through a first heating radiator, through which fluid heated by the propulsion motor flows; second heating and ventilating means including a second blower feeding air into a second duct through a second heating radiator which is powered electrically; a common delivery duct which is fed by the first and second ducts; and control means for selectively distributing the air streams delivered respectively by the first and second ducts into the delivery duct.
