Nissan develops paint that keeps cars cool in summer heat (www.asahi.com)

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.

I seriously doubt that, tests have been performed comparing black and white painted cars, and the difference was insignificant. The heat buildup in a car is due to the the sunlight entering through the windows.

To add to your comment, ceramic window tint is a night and day difference. My steering wheel, shifter, and all couldn't be touched after work. I wore driving gloves to get home. With the tint there slightly warm and the AC doesn't take half the drive to catch up, the car is cool by the first stop light.

Maybe they should sell cars with that by default instead?

Is ceramic tint different from ordinary tint?

Yes. It contains ceramic nano particles that reflect UV without interfering with visibility.

edit: I meant IR. But it reflects both.
