Mobility Transformation in Southeast Asia: Electrification, Competition, and Supply Chain Realignment

EV Momentum Is Meeting Manufacturing Ambition Across the Growing Southeast Asian Auto Industry

The five major Association of Southeast Asian Nations (ASEAN) economies, Indonesia, Thailand, Vietnam, Malaysia, and the Philippines, collectively registered 3.1 million passenger vehicles and pickup trucks in 2025. Electric vehicle (EV) adoption is accelerating across all five nations, with Build Your Dream (BYD) holding the leading position across Indonesia, Malaysia, Thailand, and the Philippines. Beyond BYD, eight other Chinese OEMs including Wuling, Geely, Chery, Changan, and GAC Aion New Energy Automobile are steadily building production and distribution scale, directly compressing Japanese OEMs' combined industry share from 60.8% to 56.2% in a single year.

Hybrid electric vehicles (HEVs) are proving to be the commercial bridge in markets where charging infrastructure is still being built. Japanese OEMs are maintaining a significant technical edge here — Toyota alone accounted for 47.4% of HEV sales in Thailand in 2025.
EV supply chain localization is accelerating, with Indonesia's nickel reserves and Thailand's mature manufacturing base drawing investment across batteries, components, and assembly infrastructure.
Unified ASEAN EV standards covering batteries, charging, and vehicle safety are in development — a standardization framework that will materially improve cross-border scalability and attract long-term capital.

Top Three Strategic Imperatives Reshaping the ASEAN Automobile Industry
Customer Value Chain Compression

Governments are incentivizing supply chain localization aggressively. Thailand and Indonesia are deploying EV-specific tax exemptions and manufacturing incentives to anchor global OEM production locally.

Transformative Megatrends

EV ecosystem remains in early stages, but momentum is building rapidly with China, Japan, and South Korea providing technology and investment benchmarks. Governments are acting on these signals.

Internal Challenges

Raw material cost volatility, particularly for lithium and nickel, is raising manufacturing costs. Environmental mandates are adding further pressure, pushing OEMs to restructure production processes.

How to Ensure Sustained Growth in Southeast Asia’s Transforming Regions

1
EV Hub Positioning: Anchor investments in Indonesia (nickel reserves) and Thailand (supply chain maturity) for scalable battery and assembly operations.
2
R&D Localization: Build domestic battery R&D and manufacturing capability to reduce import dependency and build long-term cost competitiveness.
3
Charging Infrastructure: Develop fast-charging networks aligned with growing battery electric vehicle (BEV) registrations across Vietnam, Indonesia, and Malaysia.
