What Happens When a Black Car is Exposed to the Sun?

Exposing a black car to the sun can lead to two main consequences, as outlined below: 1. Paint Peeling and Discoloration: Prolonged exposure causes the car's body temperature to rise, and when temperatures drop at night, thermal expansion and contraction can result in paint and rubber peeling and aging. The car's paint undergoes oxidation under UV rays from sunlight, leading to reduced gloss and increased likelihood of discoloration. 2. Tire and Seal Aging: Car tires exposed to high temperatures experience accelerated rubber hardening, cracking, and aging. Various sealing strips on the car also harden under sunlight, losing their sealing effectiveness. Rubber components such as door glass seals and wiper blades can also harden.
Black cars absorb a significant amount of heat when exposed to sunlight, causing the body temperature to rise sharply and turning the interior into a steamer. I remember during summer drives, if parked outside, the black roof would become too hot to touch, and the interior temperature would instantly soar above 60°C. This not only makes entering the car unbearably hot and suffocating but also poses a risk of heatstroke, especially for the elderly and children. Interior materials like leather seats can harden and crack, while plastic components may release unpleasant odors, affecting health. Prolonged exposure to sunlight also accelerates paint aging and fading, making the car look worn out. To minimize these issues, I always try to park in shaded areas or use sunshades to cover the windshield, which helps control temperature rise. Additionally, the air conditioning system must run at high speed upon startup, consuming more fuel or electricity and increasing daily expenses.
