BYD sold 12,791 cars in Thailand in January 2026, up 193.7% year-on-year for 14.2% market share and second place overall — behind Toyota, ahead of every Japanese brand except one.
That is the first time a Chinese carmaker has ranked that high in a market Japanese manufacturers have led for half a century.
The numbers
| January 2026 | Previous best | |
|---|---|---|
| BYD units | 12,791 | 6,370 (June 2025) |
| BYD share | 14.2% | 11.9% (June 2025) |
| Year-on-year | +193.7% | — |
| All Chinese brands | 42,251 units · 46.8% share | 20.2% share (Jan 2025) |
BYD roughly doubled both its previous unit record and its previous share record in a single month. Chinese brands as a group more than doubled their share of the Thai market year-on-year.
One caveat worth keeping in view: January 2026 was inflated by the EV3 registration deadline, which was extended from December 2025 to the end of January. A share of that volume was pulled forward rather than newly created.

Why BYD, and not one of the others
A ladder of price points, not a single hero car. BYD covers the market from the Atto 1 at the bottom to the Sealion 7 near the top, so a shopper at almost any budget finds a BYD in the showroom. Most rivals arrived in Thailand with one or two models.
It builds its own cells. The Blade battery is BYD’s own LFP design, which means BYD is not bidding against every other carmaker for CATL or LG capacity, and it controls both cost and quality directly.
It assembles in Thailand. BYD’s Rayong plant matters more than it looks: under EV3.5, only locally assembled cars with packs of 50 kWh or larger qualify for the subsidy at all. Imported EVs no longer do.
What this actually changes for buyers
Japanese brands responded quickly. Honda announced four new models for 2026, including the e:N2 at ฿1,429,000. Toyota moved its first electric pickup, the Hilux Travo EV, into production in Thailand. → Honda’s four new models for 2026 · Toyota Hilux Travo EV
Scale is not the same as service depth. A brand can grow showroom count far faster than it can train technicians. Anyone buying into a fast-growing brand should ask specifically about local service capacity and parts lead times — not just how many dealers exist.
Resale is set by new-car pricing. BYD cut Thai prices hard through 2024-2025, then raised them again in February 2026 when EV3.5 replaced EV3. Owners who bought at launch prices absorbed that swing. → Why used EVs lose value so fast
There has been one significant recall. BYD recalled roughly 115,000 cars in China over a power-steering and battery-related issue. It did not cover the Thai-market Atto 3, but it is worth knowing the recall history of any model before you buy. → The BYD recall explained
For BYD owners in Phuket
Every BYD sold here has a 12V battery that is not covered by the high-voltage warranty. In Phuket’s heat it lasts roughly 18-24 months, and when it fails the car will not wake up even with a full traction pack.
The most common call we get from BYD owners is exactly this: full charge showing, car completely dead.
