Nissan, in collaboration with Chinese company Radi-Cool, is testing a new 'cool paint' designed to lower vehicle temperatures by reflecting sunlight and utilizing radiative cooling. The paint, which is six times thicker than standard automotive paint, has shown to reduce exterior surface temperatures by up to 22 degrees Fahrenheit and interior temperatures by up to 9 degrees Fahrenheit. This innovation aims to reduce reliance on air conditioning, thereby conserving energy and extending the life of electric vehicle batteries. Testing began in November 2023 at Tokyo’s Haneda Airport, with promising results. While commercialization faces challenges due to the paint's thickness, Nissan continues to develop thinner, more practical versions for broader use.
