Summary
The Thai automotive market is experiencing a generational shift in powertrains, with sales of internal combustion engine-powered vehicles falling by almost half in 2025 compared to 2020. Chinese automakers (OEMs) have seen their market share grow rapidly from 3.2% in 2020 to 21.2% in 2025, with a 5.2-fold increase in sales volume, by leveraging their advantage in New Energy Vehicles (NEVs: BEVs, PHEVs, FCVs).
Led by BYD, Chinese OEMs, including SAIC, Great Wall Motor (GWM), GAC, Changan, and others, are particularly high in the sales rankings for BEVs and PEHVs. Chinese vehicles are expected to increasingly penetrate the market, entering multiple segments from urban SUVs to full-fledged off-roaders, high-end MPVs, and pickup trucks.
Chinese OEMs are undergoing a qualitative change from "exporting finished vehicles" to "localizing the entire supply chain”. In response to Thailand's electrification policy, BYD, Changan, Great Wall Motor, and others have built finished vehicle plants. At the same time, major suppliers such as CATL, SVOLT, and Yuefei New Materials (Wuhu Yuefei Sound-Absorbing New Material Co.,Ltd) have also entered the market. This report focuses on the most recent developments of Chinese automakers in Thailand.
