About Hyundai Transys
Hyundai Transys is a South Korean automotive parts maker and an affiliate of Hyundai Motor Group. Its website describes two business areas. Powertrain covers hybrid and electric drive systems, transmissions, and axle and four-wheel-drive systems, while seating covers complete seats, seat structures and mechanisms, functional components and sustainable seat materials. As of the end of 2025 the company reported 34 locations in 10 countries.
The company traces its origin to Hyundai Technology Development, set up in 1994, which was renamed Hyundai Aerospace in 1996 and took over the transmission business of Hyundai Mobis in 1997. It became Dymos in 2003 and entered the automotive seating business in 2004. In 2019 Hyundai Dymos and Hyundai Powertech were merged to launch Hyundai Transys. Its website names Baek Cheol-seung as chief executive.
According to the company's history page, it began supplying complete seats to Lucid Motors and Rivian in 2021, automatic transmissions to Stellantis in 2022 and automatic transmissions to Volkswagen in 2023. In June 2024 the Korea JoongAng Daily reported that Hyundai Motor and Kia accounted for 80 percent of its sales.
In June 2024 Hyundai Transys signed a contract to supply its electric drive system to Ceer, the Saudi electric vehicle brand established by the Public Investment Fund. The system combines the drive motor, inverter and reduction gear in one unit. The Korea JoongAng Daily valued the deal at about 3 trillion won, or $2.2 billion, with supply running for ten years from 2027, and said it was the first time the company would supply an electric drive system to a carmaker other than Hyundai Motor or Kia. TechScoop reports in September 2026 list Hyundai Transys among the partners Ceer has named. The company's history page says it started production of its TMED-II hybrid transmission in 2025.
The Korea JoongAng Daily reported in June 2024 that Hyundai Motor holds 41 percent of Hyundai Transys. For 2025 the company's website reports consolidated sales of 14.8 trillion won, operating profit of 336 billion won and 11,185 employees, including 976 in research and development.
