Chinese electric vehicle manufacturer BYD has overtaken Tesla to become the world’s largest seller of electric vehicles on a calendar year basis, marking a significant shift in the global automotive landscape. The development carries added symbolism, given that Tesla chief executive Elon Musk had publicly dismissed BYD more than a decade ago, questioning the quality of its vehicles and stating he did not view the company as a competitor. That perception has now changed sharply, as BYD’s steady rise culminated in a year where it outperformed the American automaker in overall electric vehicle deliveries.
According to figures released by BYD, sales of its battery powered vehicles climbed nearly 28 percent in 2025, reaching 2.26 million units worldwide. In contrast, Tesla delivered 1.64 million vehicles during the same period, reflecting an approximately 8 percent decline compared to 2024 and marking its second consecutive year of falling annual deliveries. Tesla’s challenges were particularly evident in the final quarter of the year, when deliveries fell about 16 percent year on year to 495,570 vehicles. Analysts had anticipated a smaller slowdown, forecasting around 449,000 deliveries for the quarter, but a combination of economic, regulatory and political factors weighed on demand.
Tesla’s performance in 2025 was shaped by intensifying competition, especially from Chinese manufacturers, alongside policy changes in key markets. The expiration of the $7,500 electric vehicle tax credit in the United States at the end of September 2025 reduced incentives for buyers, contributing to softer sales. The company also faced reputational pressure linked to Elon Musk’s public political positions, which analysts say affected consumer sentiment in several markets, including Europe. Tesla’s shares fell sharply during the first quarter of the year as investors reacted to slowing growth and rising competitive pressure, though some analysts later noted that quarterly results still exceeded more pessimistic expectations.
BYD’s ascent reflects a very different trajectory. Founded in 1995 as a battery manufacturer, the company gradually expanded into electric and plug in hybrid vehicles and became a dominant force in China’s new energy vehicle market. Leveraging China’s position as the world’s largest EV market, BYD focused on producing affordable, high volume models that appealed to mass market consumers. Its vertically integrated structure, which includes in house battery and semiconductor production, has allowed it to control costs and protect margins while scaling production. Analysts note that this approach has given BYD a competitive advantage as other manufacturers struggle with rising component costs.
Despite facing high tariffs in the United States, BYD accelerated its international expansion in 2025. The company exported more than 1 million vehicles during the year, representing a 150 percent increase compared to the previous year. December alone accounted for a record 133,000 overseas shipments. BYD is also preparing to begin production at new manufacturing facilities in Brazil and Hungary, a move aimed at bypassing trade barriers and strengthening its presence in key international markets such as Europe, Southeast Asia and the Middle East.
The contrast between the two companies is evident in their market strategies. While Tesla continues to rely on a relatively limited lineup of higher priced models, BYD has targeted entry level and mid range segments that Tesla has yet to fully address. In 2024, Tesla narrowly led BYD in total sales, delivering 1.79 million vehicles compared to BYD’s 1.76 million. The reversal in 2025 highlights how shifts in pricing, policy and consumer preferences can reshape industry leadership within a short span of time.
Analysts caution that BYD may face challenges in 2026 due to changes in Chinese subsidy policies, including the introduction of a percentage based rebate system and a new purchase tax that could affect demand for budget models. Even so, BYD’s expanding premium sub brands are seen as well positioned to attract buyers moving upmarket. As global competition intensifies, BYD’s scale, cost structure and growing international footprint have firmly established it as a central player in the evolving electric vehicle industry.
