News - Nissan developing 'cool paint' to make people feel more comfortable in their cars

Nissan showed what it called a “cool paint” to keep people inside vehicles cooler, although the coating is six times thicker, making commercialization still a challenge, reports Autoblog. Nissan Motor Co. tested the paint on vehicles scuttling around Tokyo’s Haneda airport, where there are plenty of unshaded areas that make it a good place to assess the technology. The vehicles with the special paint looked like ordinary cars, but felt much cooler to the touch. The cool paint lowered the cars’ roof-panel temperature by 12 degrees Celsius (22 degrees Fahrenheit). The test vehicles' interiors were cooler by 5 C (9 F), according to Nissan. Cooler temperatures would be an advantage in particular for EVs, where energy used by the air conditioning can affect driving range. The driving range is the maximum distance that a vehicle can travel with the available fuel—and usually when fully charged.
