- Mazda Thailand MHEV Investment supports 2027 production expansion.
- Thailand strengthens hybrid manufacturing through new incentive requirements.
Mazda Motor Corporation has secured investment promotion approval from the Thailand Board of Investment (BOI) for its joint venture, AutoAlliance (Thailand) Co Ltd, to modernize its manufacturing facility in Rayong Province. Announced on July 1, 2026, the project represents an investment exceeding THB 7.4 billion and will support production of new mild hybrid electric vehicles (MHEVs). Manufacturing is scheduled to commence in 2027, with output serving the domestic market alongside exports to Japan and ASEAN member countries.
The approved investment includes upgrades designed to improve manufacturing efficiency while supporting Mazda's long-term hybrid vehicle strategy. Automation and robotics will be introduced into critical production processes for a new B-segment SUV featuring MHEV technology. The upgraded facility will also increase the use of clean energy while ensuring vehicle production complies with Euro 6 emission standards. Through this investment, Thailand has been selected as Mazda's primary production base for MHEV models.
Thailand's incentive framework for MHEV manufacturing establishes fixed excise tax rates from 2026 through 2032. Vehicles producing no more than 100 g/km of CO2 qualify for a 10% excise tax rate, while those emitting between 101 g/km and 120 g/km are eligible for a 12% rate. The policy is intended to encourage investment in cleaner vehicle technologies while supporting the country's automotive manufacturing competitiveness.
To qualify for these incentives, manufacturers must satisfy several requirements established under the scheme. These conditions are summarized below.
Thailand MHEV Incentive Qualification Requirements
| Requirement | Condition |
|---|---|
| Minimum investment | At least THB 5 billion |
| Battery sourcing | Batteries manufactured in Thailand from 2026 |
| Propulsion components | Domestic traction motors or equivalent propulsion-assist components from 2028 |
| Vehicle technology | Minimum four of six ADAS features |
By meeting these eligibility requirements, manufacturers can access the available tax incentives while supporting Thailand's broader objective of expanding advanced hybrid vehicle production. The framework promotes local sourcing, encourages adoption of automation and robotics, strengthens clean manufacturing practices, and advances the integration of advanced driver assistance systems (ADAS) in future vehicle production.
