Thailand built 1.47M vehicles in 2024 — ASEAN's largest assembly base, 57% of output exported — and BEV share of new passenger-car sales reached ~16%, highest in the region. The listed operator stack is mid-reshape: Japanese incumbents (Toyota, Honda, Isuzu) still dominate ICE production while Chinese entrants (BYD, GWM, MG/SAIC, Changan, Neta, GAC Aion) built 5+ local BEV plants in 2023–2025 under BOI EV3.5 quota obligations. Thai Tier-1 suppliers (AAPICO Hitech, Somboon Advance, Stanley Electric, Thai Summit, Delta Electronics) are mid-pivot to EV content mix.
