How High Can the Temperature in a Car Trunk Reach in Summer?

[GenesisLee]

Tests have shown that when a car is exposed to the sun for a long time in an outdoor temperature of 40℃, the temperature inside the car can exceed 70℃, with the highest reaching up to 90℃. Specific details are as follows: 1. High Temperature: In summer, outdoor temperatures in most regions can reach around 40℃. However, most car interiors are black, which absorbs heat more easily. The enclosed environment of the car causes the temperature to rise sharply over time, creating a sauna-like effect. 2. Paint Damage: For the car's exterior, metal surfaces absorb heat more readily, leading to higher temperatures. The temperature on the hood can also become extremely high. There have been instances where people have fried eggs or grilled meat on the hood, illustrating just how high the temperature can get. High temperatures are detrimental to both the car's paint and interior. Prolonged exposure to high temperatures can cause the paint to crack or blister, damaging the body and accelerating the aging of the interior.
