Hyundai Motor Company and Kia Corporation have introduced a series of temperature control technologies aimed at improving passenger comfort and energy efficiency in vehicles. These innovations were showcased at the “Heat Tech Day” event in Seoul, reflecting the companies’ ongoing efforts to lead in automotive technology, especially in the context of electric vehicles (EVs).
The event highlighted three key innovations: Nano Cooling Film, Radiant Heating System, and Metal-Coated Heated Glass. Each technology addresses different aspects of climate control within vehicles, catering to both hot summers and cold winters.
Nano Cooling Film
This advanced material is designed to significantly lower the interior temperature of vehicles, addressing the challenges of hot weather. Unlike traditional window tints, which merely block sunlight, the Nano Cooling Film actively reduces internal temperatures by up to 12°C. Composed of three layers, it not only reflects solar energy but also allows internal heat to escape. This technology was demonstrated using two Hyundai Ioniq 6 test vehicles, where the temperature difference between a model equipped with the film and one without reached up to 12.5°C. Hyundai and Kia plan to offer this film as an optional feature for new vehicles in Korea and through dealerships internationally.
Radiant Heating System
To combat the challenges of cold weather, Hyundai and Kia introduced the Radiant Heating System. This system quickly warms passengers by targeting the lower body area with radiant heat, reaching a comfortable temperature within just three minutes. The Radiant Heating System is expected to save up to 17% of energy compared to traditional heaters, potentially increasing the driving range of EVs during winter by 7%. Hyundai plans to integrate this system into future models, including the Genesis GV90, with mass production targeted for 2026.
Metal-Coated Heated Glass
The most commercially advanced of the three technologies, Metal-Coated Heated Glass, offers a rapid solution for defrosting and dehumidifying windshields. Utilizing a world-first 48V system, this glass can clear frost in as little as five minutes, even at temperatures as low as -18°C. This is four times faster than conventional defrosting methods, while consuming 10% less energy. The glass also blocks up to 60% of solar rays, enhancing both summer and winter efficiency. Unlike older defrosting technologies that rely on visible tungsten wires, Hyundai’s solution is completely transparent, providing an unobstructed view for drivers.
While these technologies are still under development, Hyundai and Kia plan to integrate them into future vehicles, particularly high-end models and C-segment SUVs. The companies have applied for patents in major markets and are working on optimizing the mass production process to bring these innovations to the market.
