What is the temperature difference between black and white cars in summer?

In summer, the temperature difference between black and white cars can be categorized into two scenarios: 1. Exterior body temperature. A black car can be approximately 10-15 degrees Celsius hotter than a white car. 2. Interior temperature. A black car can be approximately 5-10 degrees Celsius hotter than a white car. The advantages of white cars are as follows: 1. White cars are more visible. At night, they offer relatively higher safety compared to black cars. 2. White cars are more resistant to showing dirt. In windy weather or after prolonged outdoor parking, black cars can accumulate a layer of dust overnight, making them appear dirty by morning, whereas white cars do not show dirt as prominently. 3. White cars absorb less heat. Black cars absorb more heat, leading to higher temperatures, which in turn requires the air conditioning to be set at a higher level, consuming more fuel. For older vehicles, black cars pose a significantly higher risk of spontaneous combustion in summer.

Every time I get my car washed, I chat with the technician about this. I've touched hoods of different colors during the hottest midday summer hours. Black cars are truly scorching—I've measured with a thermometer multiple times, and under sunlight, black paint surfaces can soar above 70°C, while white cars barely exceed 50°C. Getting into a black car feels like stepping into a sauna, with hot air hitting your face, and the leather seats could fry an egg. You have to open all four doors for five minutes to let the heat out before turning on the AC at full blast, whereas a white car cools down in just three minutes. If you're an office worker wanting a quick nap at noon, a white car is far more comfortable.

Last time I helped my neighbor move his car, I realized how big the difference is! Both parked in open-air parking spaces in the community for three hours, the steering wheel of my silver-gray car was only slightly warm, while the steering wheel of his black SUV was too hot to hold. The auto repair shop owner said dark-colored cars absorb more heat, with actual measurements showing a temperature difference of 15 to 20°C. What's more troublesome is that the interior of black cars ages faster, especially the plastic parts on the dashboard, which turn white and brittle after just two years of sun exposure. Now I only choose light-colored cars—not only does the air conditioning save fuel, but the leather seats are also less prone to cracking.

Our fleet conducted a test: parking black and white cars side by side under the noon sun for two hours. The black car's roof metal reached 68°C, while the white car was at 47°C. The interior temperature difference was even more dramatic—the black car's dashboard showed 52°C, while the white car was only 34°C. This 18°C gap directly determines whether you'll be sweating or comfortable when getting in. Moreover, dark-colored paint dissipates heat slowly—by the time you pick up your car after work, the black car's seats are still warm, while the white car has long cooled down. We recommend southern car owners opt for light-colored cars; otherwise, you’ll never dare to turn off the AC.

I'm the meticulous type, so last year I bought an infrared thermometer specifically to measure this. On a sunny 35℃ day, the highest recorded temperature on a black hood was 71℃, while the same spot on a white car remained stable at around 51℃. The key difference lies inside the cabin: the metal trim on the steering wheel of a black car can reach 63℃—hot enough to hurt your fingers upon touch—whereas the same component in a white car stays below 40℃. Even more surprising is the dashboard temperature: a black car's can be up to 19℃ higher than a white car's, which explains why darker-colored cars always seem to have a stronger smell of interior adhesives.

As a materials enthusiast, my focus might be different. Black paint absorbs 95% of visible light, while white paint reflects 80%, creating a fundamental temperature difference. But when actually sitting in the car, dark-colored interiors cause secondary heat absorption: black leather seats can accumulate temperatures up to 60°C, whereas light-colored fabric seats only reach about 45°C. The most critical issue is that dark-colored cars heat up faster. If you remotely start the air conditioning 10 minutes before getting off work, a white car can cool down to a comfortable 28°C, while a black car might still be above 35°C. This is particularly important for families with elderly or young children, as high cabin temperatures can pose dehydration risks.
