Nissan, in collaboration with Radi-Cool, is developing an innovative automotive paint technology designed to reduce the internal temperature of vehicles during the summer and reduce air conditioning energy consumption. This paint uses advanced metamaterials that reflect sunlight and redirect energy away from the vehicle. vehiclecreating a cooler environment inside the vehicle.
Automotive paint reduces heat in electric cars
Since November 2023, Nissan has been conducting tests at the Tokyo International Air Terminal at Haneda. During these tests, the paint was applied to service vehicles operated by All Nippon Airways (ANA). Preliminary results have been remarkable, with a reduction of up to 12 degrees Celsius in exterior temperature and 5 degrees Celsius in the interior, compared to conventionally painted vehicles.

The development of this paint has not been straightforward. Led by Dr. Susumu Miura of the Nissan Research Center, the team has worked to overcome challenges such as uniform application and durability. Currently, the paint is 120 microns thick, and they have managed to make it resistant to factors such as salt, scratches and chemical reactions, all while maintaining consistent color.
The technology promises to be especially useful in electric vehicles, where air conditioning charging in summer can significantly affect range.where air conditioning load in summer can significantly affect range. Although still in the testing phase, Nissan is hopeful that this paint will be offered in a range of colors and available for special orders in the future.
