“Once again, the principle of ‘local for local’ applies, supporting economic development, employment opportunities and knowledge transfer in Thailand and the ASEAN [Association of Southeast Asian Nations] region.” 

BMW Group’s investment in the project exceeds Bt1.6bn ($44.62m), with approximately Bt1.4bn allocated for the procurement of advanced equipment and systems.  

Since 2019, BMW Group has been manufacturing high-voltage batteries in Thailand for its locally produced plug-in hybrids.  

The Rayong plant, which produces a range of BMW, MINI, and BMW Motorrad models, serves both the Thai market and various ASEAN markets.  

In 2023, the plant’s output reached more than 12,000 cars and nearly 11,000 motorcycles. 

The latest development comes after BMW Group announced its plans to build an advanced Talent Campus in Munich, Germany, last December. 

This campus will be constructed on the location of a former car park in Riesenfeldstrasse.
