An electromagnetic compatibility simulating apparatus for an automobile including an electromagnetically shielded cell having a wall dividing the interior of the cell into a first chamber for the automobile and a second chamber. Road simulator units are mounted within the second chamber. Dynamometers are mounted within the second chamber in driving relation with the road simulator units. The wall has windows for allowing driving contact of the road simulator units with the road wheels, and blower openings for allowing air feed from blowers. Electromagnetic wave absorbers and reflecting wall portions are disposed on the windows. Expanded metals cover the blower openings or metal pipes are disposed between the blower and the blower openings. The wall has inspection windows with shutters on which electromagnetic shielding net is disposed. A controller is disposed outside the first and second chambers. Conductors connect the controller with the dynamometers and blowers. First and second filters are disposed in the conductors.
