Hyundai's nano cooling film reduces interior temperatures by up to 22.2 degrees fahrenheit in pakistani tests

New technology combines tinted windows and solar cells to provide cooling and energy in hot weather

Hyundai has developed a window tint that claims to help keep vehicle interiors cooler and reduce energy consumption on air conditioning. The tint, called Nano Cooling Film, is made up of three layers that work together to block external heat and radiate internal heat towards the outside of the vehicle. The company recently tested the film on 70 customer cars in Lahore, Pakistan, where temperatures can reach over 122 degrees Fahrenheit. According to Hyundai, interior temperatures in the test vehicles dropped significantly, with temperature decreases near the driver's head of 19.8 degrees Fahrenheit compared to conventional tinting and 22.2 degrees compared to the same vehicle without tinted windows at all. While Hyundai is not discussing commercialization plans, the company notes that the tint can be applied in tandem with conventional tint film where regulations allow.
