Thailand has secured more than $4.1bn (around THB137bn) in investment commitments for its electric vehicle industry, reinforcing its position as Southeast Asia's leading automotive manufacturing centre.
Figures released by the Thailand Board of Investment (BOI) show the funding covers 198 projects spanning the entire EV supply chain, including battery electric vehicles (BEVs), hybrid and plug-in hybrid models, battery production, key components and charging infrastructure, according to Thailand Business News.
The investment momentum comes as international carmakers continue to diversify manufacturing bases and strengthen supply chains across Southeast Asia amid shifting global economic and geopolitical conditions.
Rather than concentrating solely on fully electric vehicles, Thailand has adopted a broader strategy supporting Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs) and BEVs, allowing manufacturers to expand production across multiple technologies.
The approach has already translated into stronger domestic demand. In 2025, electrified vehicles accounted for more than 40% of all new vehicle registrations in the country. Hybrid models made up the largest share at 21.8%, while battery electric vehicles represented 19.6%.
BOI data also highlights significant investment across different segments of the industry. Battery electric vehicle manufacturing attracted approximately THB39.5bn through 18 projects, creating annual production capacity exceeding 370,000 vehicles.
Meanwhile, hybrid and plug-in hybrid vehicle projects secured a combined THB39.3bn across 14 investments. The expansion builds on Thailand's long-standing automotive industry and the established presence of Japanese manufacturers, which have played a leading role in hybrid vehicle development.
The latest investment commitments reinforce Thailand's ambition to strengthen its role as a regional hub for next-generation vehicle production while supporting the global transition towards cleaner transport technologies.
