China's BYD is set to overtake Elon Musk's Tesla as the world's biggest seller of electric vehicles (EVs), marking the first time it has outpaced its American rival for annual sales.

On Thursday, BYD said that sales of its battery-powered cars rose last year by almost 28% to more than 2.25 million.

Tesla, which is due to reveal its total sales for 2025 later on Friday, last week published analysts' estimates suggesting that it had sold around 1.65 million vehicles for the year as a whole.

The US firm has faced a tough year with a mixed reception to new offerings, unease over Musk's political activities and intensifying competition from Chinese rivals.

Chinese firms such as Geely, MG, and BYD - now the country's largest electric car company - have put pressure on Western rivals by pricing their vehicles below established brands.

In October, Tesla responded by launching lower-priced versions of its two best selling models in the US in a bid to boost sales.

Musk, who is already the world's richest man, is tasked with significantly boosting Tesla's sales and stock market value over the next decade to secure a record-breaking pay package. The deal, which was approved by shareholders in November, could see him getting a payout of as much as $1tn (£740bn).

As part of the agreement, Musk also has to sell a million humanoid robots over the next ten years. Tesla has invested heavily in its "Optimus" product and self-driving "Robotaxis".

Tesla sales slumped in the first three months of 2025 after a backlash against Musk's role in US President Donald Trump's administration.

Besides Tesla, the multi-billionaire's business interests also include the social media platform X, the rocket firm SpaceX and the Boring Company, which digs tunnels.

Those commitments, along with running Trump's Department of Government Efficiency (Doge), led some investors to suggest that Musk was not focusing enough on Tesla.

Since then Musk has pledged to "significantly" cut back his role in the US government.

Despite BYD's rise in recent years, its sales growth slowed in 2025 to the weakest rate in five years, in part due to fierce competition in China, its key market.

Still, BYD remains a global EV powerhouse as its prices often undercut rival carmakers.

The Shenzhen-based company's rapid expansion - especially in Latin America, South East Asia and parts of Europe - comes despite many countries imposing steep tariffs on Chinese EVs.

In October, BYD said the UK had become its biggest market outside China. The firm said that its sales in Britain surged by 880% in the year to the end of September, driven by strong demand for the plug-in hybrid version of its Seal U sports utility vehicle (SUV). (BBC)
