BYD (HKG: 1211) recorded 383,453 total vehicle sales in May 2026, of which 376,990 were new energy passenger cars, setting an all-time May record and extending its position as China's top-selling automaker as the domestic new energy market delivered its strongest May result on record.

China's Passenger Car Association (CPCA) released preliminary wholesale data on June 2, 2026, showing 1.36 million new energy passenger vehicles wholesaled across the country in May — a 12% gain year-on-year and 11% month-on-month. It was the first time this year the market achieved double-digit growth on both measures in the same month.

Twenty automakers cleared the 10,000-unit monthly threshold, and CPCA noted that several brands set all-time highs for May new energy wholesale — among them BYD, Chery, Tesla China, Leapmotor, and NIO.

Broader conditions during the month tilted sharply in favour of electric vehicles. Disrupted shipping through the Strait of Hormuz prompted two rounds of domestic retail fuel price adjustments, cumulating at nearly 400 CNY (c. $59) per tonne, a meaningful increase in the monthly running cost of petrol and diesel vehicles that accelerated buyer consideration of electric alternatives.

Within BYD's lineup, the Dynasty and Ocean series together contributed 330,000 units in May. The off-road sub-brand Fang Cheng Bao added 30,000, the premium Denza brand 16,000, and ultra-luxury arm Yangwang 286 units.

Overseas deliveries exceeded 160,000 vehicles in May — up from more than 130,000 in April — while domestic sales ran at approximately 223,000 units, underscoring the degree to which exports have become a structural pillar of BYD's monthly volume rather than a swing factor.

BYD's total May sales were essentially flat year-on-year at plus 0.3%, though the 20% month-on-month rebound from April's 314,000 units suggested meaningful demand recovery after a subdued start to 2026. On a cumulative basis, BYD passenger car sales for January through May reached 1,380,083 units — still 20.5% below the same period in 2025 — indicating the full-year recovery remains a work in progress.

The competitive field behind BYD showed notable realignment. Geely (HKG: 0175) held second place in new energy wholesale with 131,037 units, followed by Chery at 92,905.

Tesla (NASDAQ: TSLA) China recorded 85,982 units in May — up 39.4% year-on-year and 8% month-on-month — its highest monthly delivery total of 2026 and a seventh consecutive month of growth. The figure encompasses both domestic retail and exports from Giga Shanghai to Asia-Pacific and European markets.

Leapmotor (HKG: 9863) climbed to fifth in the new energy wholesale rankings with 81,569 units, an 81% year-on-year surge that left it within roughly 4,400 units of Tesla China.

Further down the field, SAIC-GM-Wuling posted 69,103 NEV units and SAIC Passenger Cars 46,643. NIO (NYSE: NIO) delivered 37,705 vehicles, GAC Aion 34,208, and Li Auto (NASDAQ: LI) 33,350.

Whether BYD can erase the 20.5% year-to-date shortfall it carries into the second half of 2026 hinges on whether its export trajectory holds — and on how aggressively Leapmotor, already at Tesla China's shoulder in monthly wholesale, pushes into segments where BYD has long held the dominant position.
