Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.

The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.

The company said the coating material can help rein in the temperature rise not only on the car’s body but also in the vehicle when exposed to direct sunlight.

    Sorry can’t find it, all I can find in english are some where the data isn’t clear.
    If a white car has brighter interior it will stay slightly cooler, I cannot find a test where everything is the same except the color of the car.
    What I can say however, is that the test I saw was performed in Denmark. It’s possible countries with hotter climates may observe some difference?

    Obviously the main source of heat is what enters through the windows, and how much is reflected out again does have an influence.,

    If a white car has white seats and interior, they will obviously not heat as much as black seats and interior.

    The white color on the exterior will also reflect more light into the car, except maybe at noon.

    Edit PS:
    I linked the danish test in a new response.

      A lot of things seem obvious but turn out not to be, or not as much as I’ve first thought. Hence the usefulness of data and studies rather than mere reasoning.
