The present invention relates to a ventilation system 24 for a land vehicle 10. The ventilation system 24 comprises an inlet duct 26 for allowing exterior air to enter a cabin of the vehicle. The inlet duct 26 has a source port 38 located at an exterior of the vehicle 10 and the inlet duct 26 also has an exhaust port 40 located within a cabin of the vehicle 10. The ventilation system 24 has an outlet duct 28 for allowing interior air to exit the cabin of the vehicle 10. The outlet duct 28 has a source port 44 located within the cabin of the vehicle 10 and the outlet duct 28 also has an exhaust port 46 located at an exterior of the vehicle. The ventilation system 24 has an air propulsion element to cause selectively an airflow between the cabin interior and the vehicle exterior; wherein the source port 38 of the inlet duct 26 and the exhaust port 46 of the outlet duct 28 are collocated in a zone of substantially equivalent dynamic pressure, in-use. |
