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.

Do they? I mean yes, because the ICE engines just constantly dump a ton of heat out, but does a parked car? Is there data on that?

Yes, just like "rock / gravel gardens" or whatever you call them in English, which are now banned in a lot of places for one reason being that exact same phenomenon of contributing to the urban heat island effect. They soak up the heat from the sun like a battery and then slowly release it into their environment, keeping it warm. It's super obvious as a pedestrian.
