What is the highest temperature inside a car exposed to the sun in summer?

In summer, the highest temperature inside a car exposed to the sun can reach 70 degrees Celsius. In addition to high temperatures, prolonged exposure to the sun can cause significant damage to the vehicle. Here are the details: 1. Damage to the paint: Many car surfaces have thin paint layers. Prolonged exposure to the sun can accelerate paint aging and fading, causing the car body to lose its luster, affecting its appearance, and even leading to paint cracking, bulging, or peeling, which shortens the paint's lifespan. 2. Damage to tires: Tires are made of rubber. Extended exposure to sunlight can cause deformation and cracking of tires, reducing their service life. Additionally, tire pressure is affected by temperature changes. Under conditions of prolonged high-speed driving or sudden braking, localized overheating can easily lead to tire blowouts.
In summer, when cars are exposed to direct sunlight, the interior temperature can reach as high as 60 to 80 degrees Celsius, which is quite astonishing. As a frequent driver, I've noticed that black cars or those with dark interiors absorb heat the most, with temperatures soaring to dangerous levels within just half an hour of parking. Contributing factors include the external temperature—if it's over 35 degrees outside, the car's interior can be 20-30 degrees hotter; the windows block heat dissipation, creating a greenhouse effect that causes heat to accumulate rapidly; and materials like plastic and fabric inside the car release heat slowly. This not only makes the seats uncomfortably hot but can also lead to heatstroke or damage to phone batteries. I recommend parking in the shade whenever possible, using sunshades, or leaving a window slightly open for ventilation. Before heading out on hot days, never leave children or pets in the car—safety comes first, and these small habits can save a lot of trouble.
Hey, don't underestimate how hot a car can get under summer sun! I've personally seen thermometers spike over 70°C, and this is no tall tale. The reason is simple: direct sunlight enters through windows, and heat absorbed by seats can't dissipate, causing temperatures to rise over time. Dark-colored cars heat up even faster due to their heat-absorbing nature. The risks are real—aside from making you sweat uncomfortably, it can damage water bottles or electronics left inside. I always use a sunshade on the windshield when parked, which works well. Personal tip: When opening the car door, a wave of hot air rushes out—remember to ventilate first before getting in. These simple tricks are effective; give them a try on scorching days.
