Key Trends and Recent Developments
The South Korea auto parts manufacturing market is driven by Hyundai Motor Group's record domestic investment commitment, the EV transition requiring retooling from ICE to electric drivetrain components, Bosch Korea factory expansion, the US tariff environment redirecting Korean auto parts strategies, and AI-enabled manufacturing automation investment from Hyundai and global tier-1 suppliers.
Hyundai Motor Group announced a landmark USD 86.5 Billion domestic investment plan for South Korea on November 2025, covering the 2026-2030 period. The plan includes USD 86.5 Billion in EV capacity, AI manufacturing, robotics, and supply chain support for tier-1 to tier-3 Korean auto parts suppliers. Hyundai committed to covering all US tariff costs incurred by tier-1 suppliers in 2025 and developing new support programmes for tier-2 and tier-3 auto parts manufacturers to stabilise the domestic supply chain.
South Korea's electric vehicle sales growth in 2025 accelerated the auto parts manufacturing industry's pivot from internal combustion engine components to EV battery systems, electric motors, power electronics, and advanced thermal management components. Korean auto parts manufacturers are retooling production lines from ICE-specific components such as exhaust, transmission, and fuel injection parts toward EV-compatible battery packs, power inverters, and high-voltage wiring harnesses in collaboration with LG Energy Solution, Samsung SDI, and SK On.
Robert Bosch GmbH's Korean subsidiary invested KRW 200 Billion (approximately USD 178.5 Million) in its Daejeon factory in 2025 to establish a new gasoline engine parts production line targeting Hyundai Motor, Kia, and Genesis. The investment reinforces South Korea's role as a strategic auto parts manufacturing hub for Bosch's Asia Pacific supply chain.
Hyundai Motor Group announced its 2025 domestic South Korea investment plan of KRW 24.3 Trillion (approximately USD 17 Billion) in January 2025, the largest ever annual investment commitment by the group. The investment targets electric vehicles, software-defined vehicles, hydrogen vehicles, and autonomous vehicle technology, with significant funds allocated to Hyundai Mobis auto parts integration and advanced manufacturing capacity at Korean plants supporting Hyundai Motor and Kia export production.
