Japanese car maker Nissan has developed a new type of paint that keeps cars cooler. The paint lowers the temperature inside cars that are parked in sunlight. The paint can keep a car 12ºC cooler than cars with regular paint. The new paint will also reduce the need for air conditioning. This means there is less pressure on a car's battery. The paint was developed in partnership with a Chinese company called Radi-Cool, a specialist in heat-cooling products. Nissan said: "The project is part of [our] pursuit of…innovations that empower journeys, and help create a cleaner, more sustainable society." The paint is currently only available in white. Nissan hopes to make other colours in the future.

The leader of the "cool paint" project is Dr Susumu Miura. He is a manager at the Nissan Research Center near Tokyo. His team started developing the paint in 2021. Their current paint is about six times thicker than standard automotive paint. This will make cars a little more expensive. Dr Miura spoke about his work. He said: "My dream is to create cooler cars without consuming energy." He added: "This is especially important in the electric vehicle era, where the load from running air-conditioning in summer can have a sizeable impact on the [condition of the battery]." He hopes vehicles like ambulances that spend most of the day out driving will have the paint.
