Is the trunk of a sedan ventilated?
2 Answers
Car trunks have ventilation, but the airflow is minimal. Below is additional information on trunk usage: 1. Do not store flammable or explosive items: Neither the cabin nor the trunk should contain flammable or explosive materials. In hot weather, a parked car exposed to sunlight can reach internal temperatures of 60-70 degrees Celsius, which may cause such items to spontaneously combust. Additionally, collisions during driving could also lead to spontaneous combustion of these items. 2. Avoid overloading the trunk: Carrying excessive items in the trunk may result in penalties, as traffic police cannot determine whether the transport is illegal. 3. Do not store valuables: Keeping valuables in the trunk is unsafe. Thieves can easily access them. Since the trunk is connected to the second row of seats, breaking a window allows thieves to reach into the trunk from the second row.
From a design perspective, the trunk of a sedan is usually not completely airtight—it does have a certain degree of passive ventilation design. For example, many cars have small vents or mesh hidden in the trunk lining or corners. These aren’t meant to blow air like an AC system, but rather to balance air pressure when closing the trunk. Otherwise, every time you shut the trunk lid, the air would have nowhere to go, resulting in a loud slamming noise and potentially damaging the sealing strips. These vents also help dissipate moisture, preventing water accumulation or mold in the trunk—especially when wet items are placed inside on rainy days. They allow slow air circulation, reducing odor buildup. However, this ventilation is very subtle, so don’t expect it to dry things quickly. In some older models, the vents might be clogged and need cleaning, otherwise moisture issues could worsen. Regularly checking the trunk’s ventilation is helpful for long-term vehicle maintenance.
