South Korean auto majors Hyundai Motor Company and Kia Corporation recently unveiled three technologies designed to closely regulate vehicle interior temperature to deliver enhanced passenger comfort and energy efficiency at ‘Heat Tech Day’ in Seoul.

The event showcased Hyundai Motor and Kia’s research and development achievements in temperature control, a crucial aspect of passenger comfort. These technologies they say not only improve comfort but also save energy, allowing efficient management of vehicle energy in the era of electrification. The three technologies unveiled were:

Nano Cooling Film – this material significantly lowers interior temperature in hot weather when applied to vehicle glass.

Radiant Heating System – quickly and efficiently raises the perceived temperature around passengers in cold weather.

Metal-Coated Heated Glass – a world-first 48V system quickly transmits heat from the electrically powered metal coating to the glass, removing frost and moisture.

All three technologies are at the level of technological maturity suitable for mass production.

Young Ho Jung, VP & Head of Thermal Energy Total Development Group, Hyundai Motor Company said, “The three technologies unveiled today are closer to customers than any other technology. We are developing technologies to provide the most pleasant environment, considering every moment that customers experience in mobility.”

In July 2023, Hyundai Motor and Kia showcased various advanced nano-material technologies – particularly Nano Cooling Film, which can significantly lower a vehicle’s interior temperature.
