New York: Growing Chinese auto giant BYD stands poised to officially surpass Tesla as the world's biggest electric vehicle company in annual sales.

The two groups are expected soon to publish their final figures for 2025, and based on sales data so far this year, there is almost no chance the American company led by Elon Musk will retain its leadership position.

At the end of November, Shenzhen-based BYD, which also produces hybrid vehicles, had sold 2.07 million EVs so far in 2025.

Tesla, for its part, had sold 1.22 million by the end of September.

Tesla's September figures included a one-time boost in sales, to nearly half-a-million vehicles in a three-month period, before the expiration of a US tax credit for buyers of electric vehicles -- which ended under legislation backed by President Donald Trump, a climate change skeptic.

But Tesla's sales in the coming quarter are expected to fall to 449,000, according to a FactSet analysis consensus. That would give Tesla about 1.65 million sales for all of 2025, a drop of 7.7 percent and well below the level BYD had attained by end November.

Deutsche Bank, which projects just 405,000 Tesla EV sales during the fourth quarter, sees the company's sales down by around one-third in both North America and Europe, and by one-tenth in China.

Transition period
Industry watchers say it will take time for EV demand to reach a level of equilibrium in the United States following the elimination of the $7,500 US tax credit at the end of September 2025.

Even prior to that, Tesla had seen sales struggle in key markets over CEO Musk's political support of Trump and other far-right politicians. Tesla has also faced rising EV competition from BYD and other Chinese companies and from European giants.

"We believe Tesla will see some weakness on deliveries" in the fourth quarter, said Dan Ives of Wedbush Securities.

Sales of 420,000 would be "good enough to show stable demand," with Wall Street "laser focused on the autonomous chapter kicking off in 2026," Ives added, referring to plans for self-driving vehicles.

Even as it has grown quickly, BYD has faced challenges in its home market.

With profitability in China weighed down by price-wary consumers, the company has sought to strengthen its foothold in foreign markets.

BYD is "one of the pioneers to establish overseas production capacity and supply chains for EVs," Jing Yang, Director of Asia-Pacific Corporate Ratings at Fitch Ratings, told AFP.

"Going forward, its geographical diversification is likely to help it to navigate an increasingly complicated global tariff environment," said Yang.
