Chinese government tightens regulations on BYD amid slowdown in electric vehicle sector

The Chinese government has adopted stricter measures for the electric vehicle sector, focusing on manufacturers such as BYD, the country’s largest producer. Essa change occurs in light of signs of slowdown in the domestic market, marked by excess capacity and intense price competition. Especialistas point to structural challenges in industrial policy, which previously prioritized broad subsidies and now seeks greater quality and innovation.

The fatal accident involving the Xiaomi SU7, which occurred in March 2025 on a highway in Anhui, accelerated this cautious stance. The vehicle was operating in driving assistance mode when it collided with a concrete barrier, resulting in three deaths. Esse incident highlighted risks in autonomous driving technology and influenced restrictions on advertising and testing of advanced systems.

Slowdown in the internal market

The electric vehicle sector in China sees slower growth in 2025 after years of accelerated expansion. Vendas of new energy vehicles reached record levels, but projections indicate a reduction in the pace for 2026, influenced by the gradual withdrawal of tax incentives.

Manufacturers face high inventory and reduced profit margins due to price wars. Market leader BYD adjusted sales targets downward and slowed production expansions at domestic factories.

• Reduction in work shifts in some units.
• Delays in new assembly lines.
• Greater focus on exports to compensate for weak domestic demand.

These adaptations reflect the need to balance supply with real consumption.

General regulatory tightening

Chinese authorities have excluded new energy vehicles from the five-year plan of strategic industries for 2026-2030. Essa decision signals the end of broad subsidies, with an emphasis on measures aimed at innovative and high-quality products.

Full exemption from purchase tax for electric cars ends in December 2025, halving from 2026. Requisitos stricter technical requirements apply to minimum electric range and energy consumption to qualify for tax benefits.

These changes aim to eliminate competition based solely on price and promote sustainable development in the sector.

Impact of the accident with Xiaomi SU7

The incident with the Xiaomi SU7 in March 2025 generated national repercussions and led to bans on terms such as “autonomous driving” in advertisements. Sistemas of assistance now clearly classifies as level 2, requiring constant attention from the driver.

Public testing of advanced features requires official approval, limiting frequent over-the-air updates. The focus shifts to integration with infrastructure, prioritizing technological maturity over races for resources.

Videos on platforms such as Douyin and Bilibili highlight security testing, reflecting greater demand for reliability among Chinese consumers.

Challenges in autonomous driving

Development of autonomous driving technologies faces increased scrutiny after fatal crash. Reguladores prohibit exaggerations of capabilities, requiring clear disclosure of limitations and risks.

Future level 3 operations emphasize combining vehicle sensors with road infrastructure. Essa approach seeks global trust, essential for Chinese digital strategy.

Chinese consumers increasingly prioritize security in purchasing decisions, in addition to convenience.

Adjustments at BYD and industry leaders

BYD reports decline in monthly domestic sales in 2025, focusing on foreign markets to maintain growth. Outras automakers, such as Geely and Xiaomi, gain ground in affordable segments.

The sector is dealing with accumulated debt and the need for innovation to overcome excess capacity. Políticas Governments encourage consolidation, eliminating low-quality products.

Changes to tax incentives

Tax benefits for electric and plug-in hybrid vehicles are progressively reduced from 2026. Modelos must meet higher efficiency and autonomy standards for qualification.

This transition stimulates a rush for purchases at the end of 2025, but projects a subsequent slowdown. Autoridades target a mature market, less dependent on state support.

Priority to vehicle safety

Accidents highlight the importance of strict standards in batteries and assistance systems. Reguladores tighten standards to reduce fire risks and crashes.

Consumers access educational content in popular applications, reinforcing real security tests. Essa trend influences choices, valuing reliable classifications such as C-NCAP.

The electric vehicle sector in China is transitioning into a maturation phase, with stricter regulations driven by structural challenges and safety incidents. Fabricantes like BYD adapt to an environment with greater demands on quality and innovation. The balance between rapid growth and sustainability defines the future of the market.
