Nissan has made a paint that keeps cars cooler in sunlight. A car can be 12ºC cooler. It means using air conditioning less. This helps a car's battery. Nissan said: "The project is part of [our] pursuit of…innovations that empower journeys, and help create a cleaner, more sustainable society."

The "cool paint" project team got together in 2021. The paint it made is six times thicker than standard paint. This will make cars more expensive. The team leader said: "My dream is to create cooler cars without consuming energy." This is important because electric cars need battery power for air conditioners.
