- BYD’s Rayong plant surpassed 130,000 NEV deliveries in Thailand two years after opening.
- The factory, with 150,000-unit capacity and 50% local parts, created over 5,000 jobs.
- BYD ranked third in H1 Thailand registrations and led June BEV sales with the Atto 3.
BYD’s Thailand plant has reached its two-year production milestone, with the company announcing that cumulative new energy vehicle (NEV) deliveries in the Thai market have exceeded 130,000 units.
The milestone delivery vehicle was a BYD Sealion 5 DM-i, delivered to Usa Samkham, the actress who played the grandmother character in the Chinese film “Dear You.”
During the event, the BYD Sealion 5 DM-i Standard Edition also opened for pre-sales in Thailand, with a pre-sale price of THB 699,900 ($20,890).

Located in the WHA Industrial Estate in Rayong Province, the BYD Thailand plant is the company’s first overseas passenger vehicle manufacturing facility and officially began operations in 2024.
The plant has a designed annual production capacity of 150,000 vehicles.
It currently produces five locally manufactured models, including the Dolphin, Atto 3, Seal 5 DM-i, Sealion 5 DM-i and Sealion 6 DM-i.
All of these models have received Made in Thailand (MiT) certification from the Federation of Thai Industries.
Over the past two years, the Rayong facility has created more than 5,000 jobs, with Thai employees accounting for around 93% of its workforce. The plant’s local parts sourcing ratio has reached 50%.
In terms of market performance, Thailand has become one of BYD’s key markets in Southeast Asia.

Data from Thailand’s Department of Land Transport showed that BYD recorded 4,832 new vehicle registrations in June 2026, excluding the Denza brand.
During the first half of the year, BYD accumulated 25,890 registrations in Thailand, ranking third in the overall market and becoming the best-selling Chinese automotive brand in the country.
In June, BYD’s battery electric vehicle (BEV) registrations ranked first in Thailand’s EV market.
The Atto 3 (Yuan Plus in China) continued to perform strongly, remaining among the top three best-selling pure electric models in the country.
Thailand has long been a major automotive manufacturing hub in Southeast Asia, with Japanese brands such as Toyota and Honda traditionally dominating the market.

However, as EV supply chains shift and Thailand’s government promotes vehicle electrification, Chinese automakers have been expanding their presence through local production, dealership networks and supply chain partnerships.
During the first half of this year, Chery’s Omoda and Jaecoo brands recorded 20,163 sales in Thailand, up 1,066.8% year on year and ranking fifth in the market.
SAIC Motor’s MG brand recorded 16,263 units, GAC Aion reached 10,393 units, and Great Wall Motor delivered 8,703 vehicles, with all three brands ranking among Thailand’s top 10 automakers.
BYD is currently accelerating its global expansion strategy. Beyond Thailand, the company is advancing overseas production projects in markets including Brazil, Hungary and Turkey.
