Some cities around the world prohibit manufacturers from selling new black cars, why?
Have you ever wondered why cars when exposed to the scorching sun of summer days become a "sauna" in the true sense? Turns out, they have a similar relationship with the way you still choose light-colored clothes to avoid the sun.
We have known for a long time that dark colors will absorb more heat from sunlight while light clothes will reflect better. That same idea turned out to be used even in cars.
In the 2008-2009 period, the state of California, USA, considered banning the sale of black cars, not because of concern for the comfort of residents but because of concerns about the adverse environmental impact of the car. Black absorbs heat from sunlight.
An experiment by YouTube channel BuzzFeedBlue also put two black and white cars in the sun. The results showed that the surface temperature of the black car increased to 76 degrees C, while the white car was only 58 degrees C.
The black car has a temperature of up to 76 degrees C .
. while the white car was only 58 degrees Celsius
So it can be temporarily concluded that the idea that cars are black or darker forms is easier to heat in summer is completely correct . Therefore, if possible, you should use sunshades that reflect sunlight to the vehicle.
Similarly, researchers have shown that black-painted cars are usually hotter than light-colored cars in the sun, so they will consume more energy to cool the cabin, which This wastes fuel and increases the impact of environmental pollution.
Specifically, in a 2011 study by the Berkeley Lab Division of Environmental Energy Technology in the US, it was discovered that white, silver and other light paint colors increase a vehicle's fuel efficiency. .
Some cities around the world prohibit manufacturers from selling new black cars, which is not related to traffic density but to keep the environment from being affected.
Studies also show that a hotter car will require more energy to cool and keep the car cool. This wastes fuel, increasing toxic emissions from a vehicle.
It was demonstrated in a study on a silver Honda Civic and a black car that showed interesting findings, the light reflected about 60% of the sunlight on the silver car. with black cars. The black car needs 2% more fuel (because the air conditioner has to increase its operation), leading to an increase in carbon dioxide emissions of 1.9%, and an additional 1% of other harmful emissions for with the black car out to the environment.
As such, it's clear to see that a black car will probably make your wallet a bit thinner because it consumes more fuel than other color cars.
Besides, the quality of the interior of the black cars is also often subjected to higher temperatures than normal when parked in the sun, degraded quickly. Another factor affecting health is that when the cabin temperature rises rapidly and highly, it will produce toxic wastes of organic compounds from plastics, adhesives, artificial leather, vinyl . the cabin, in the summer these toxins soar under the influence of UV rays and heat, when people get into the car and often use the quick cooling mode of the air conditioner to deal with the temperature, will accidentally stir The gas is contaminated with toxins circulating throughout the cabin, which is very harmful to health.
However, what if you like a black car so much? Avoid maximizing parking in the sun, slightly lower the windshield if you need to park for a long time, straighten the windshield to expel the hot air before turning on the air conditioner, consider changing the color of the roof. bright colors, use anti-heat film .
