For those who believe modern cars are already overloaded with technology, Nissan is set to introduce a groundbreaking innovation. The company is developing a novel type of exterior paint that employs electromagnetic waves to reduce the temperature of both the car’s surface and interior. Although still in the experimental phase, initial results are promising.
In partnership with Radi-Cool, a firm specializing in cooling technologies, Nissan aims to enhance traditional radiative paint methods. While radiative paints have long been used in architecture to maintain cooler interior temperatures, these formulations are generally thick and less durable compared to automotive finishes, often applied with rollers.
However, Nissan’s new paint is intended for use with spray guns and compatible with clear topcoats. Despite being six times thicker than standard automotive paint, it incorporates two key microstructure components for cooling. The first component reflects near-infrared rays, a common cooling strategy, while the second generates electromagnetic waves that counteract rather than reflect sunlight, effectively reducing heat transfer to the vehicle’s interior.
Dr. Susumu Miura, the project’s senior manager, shared his vision: “I aim to create cooler cars without relying on additional energy.” This is particularly crucial for electric vehicles, where air conditioning use can impact battery charge. Although Nissan has not disclosed detailed mechanisms of the paint’s technology, tests indicate a temperature reduction: 12 degrees Celsius on the exterior and 5 degrees Celsius inside.
As for when this innovative paint will be available, development is still underway. Nissan hopes to refine the paint to make it thinner for easier application, and if it reaches production, it is likely to be offered on a special-order basis for select models.
