New regulation in China limits acceleration of electric vehicles to reduce traffic accidents

Ministério of Segurança Pública of China introduced a bill focused on limiting the initial acceleration of automobiles on public roads. The measure directly affects the market for high-performance electric and hybrid cars. The text requires a standard configuration that takes at least five seconds to reach the 100 km/h mark. The authorities’ main objective involves preventing collisions caused by unintended acceleration in dense urban areas.

The technical proposal replaces previous standards and introduces mandatory technologies that restrict engine power through software. The document remains in the public consultation phase until the beginning of 2026. Representantes from the government highlight the need to prepare drivers for the use of high-performance modes. Activating maximum power will require manual and conscious action from the driver before each journey.

Restrição in the response time of electric motors

The ability to go from zero to 100 km/h in less than five seconds will be blocked in the standard driving mode of all passenger vehicles. Essa safety configuration comes into operation automatically whenever the driver starts the car. The only exception provided for in the document covers start-stop systems. The government justifies the intervention based on the increase in recent incidents. The instantaneous torque of electric motors often surprises drivers with little driving experience.

Recent sports Modelos exemplify the main focus of the new technical regulation. The Xiaomi SU7 Ultra reaches this speed mark in just 1.98 seconds. Automakers will need to modify cars’ operating systems to force intentional selection of sport modes. The rule also covers cars powered by internal combustion. The biggest impact falls on the electric car industry, a sector where starts under three seconds have become a common standard in recent launches.

Dados officials show that incidents involving uncontrolled acceleration have registered a 25% increase in urban areas since 2023. Traffic authorities associate this statistic with the popularization of affordable models that deliver supercar performance. The public purchasing these vehicles has an average age of 35 years. Driver training schools use fleets with accelerations greater than five seconds, a parameter that served as the basis for drafting the law.

Prevenção fault and battery monitoring

Electrically powered cars and plug-in hybrids face new specific demands on energy storage components. The bill determines the installation of technologies capable of suppressing accidental accelerations when the car is stopped or traveling at low speed. The system acts by immediately limiting engine power. The instrument panel must emit audible and visual warning signals to the driver during intervention.

High voltage batteries must demonstrate resistance against extreme thermal events without creating an immediate risk of fire. The equipment will continuously detect irregularities in the energy cells. Automatic anomaly recording creates a detailed history to facilitate future technical inspections. Electric buses over six meters long receive even stricter protection rules. Passenger compartments must withstand the spread of fire for at least five minutes after the emergency alarm is triggered.

The automatic cutting of electrical circuits occurs in collision situations detected by the vehicle’s sensors. The system identifies sudden speed changes greater than 24 km/h within 150 milliseconds. Advanced driver assistance features operate under new safety conditions. Activation of these autonomous tools requires prior biometric verification. The user login serves to confirm that adequate training has been carried out on how the system works.

Modificações mandatory on doors and windows

The physical structure of car doors undergoes updates focused on accessibility during emergency situations. Legislation requires that each cabin occupant has access to at least two different exit routes. The project addresses the difficulty of rescue in recent accidents involving door handles embedded in the bodywork.

• Doors must have mechanical opening handles on both the inside and outside.
• Electronic locking systems must unlock the locks automatically after the airbags deploy.
• The detection of thermal faults in the battery also triggers the immediate release of all vehicle doors.

Windows receive prohibitions related to the use of reflective films that impair the field of vision. The glazed area around the driver must maintain a light transmission rate of at least 70%. Fabricantes of automobiles that rely on highly aerodynamic designs will need to adapt their structural designs. The implementation of the rules standardizes safe escape routes in the event of severe collisions.

Industry Adaptação and approval timeline

Ministério from Indústria and Tecnologia from Informação accelerated the process of reviewing standards for connected vehicles throughout 2025. The official timeline sets February 2026 as the deadline for the integration of pedal error detection systems into new models. The month of July of the same year marks the beginning of the implementation of rules against fire in battery packs. The Chinese government hopes to align local standards with international requirements by the end of the decade.

Automotive brands adjust their marketing campaigns in light of the new regulatory scenario. Advertisements that previously emphasized acceleration times below two seconds are losing space. The standard promotes the development of dual-mode software that does not require the installation of additional hardware. Exporting companies design adaptations on a global scale to maintain competitiveness.

The Chinese market recorded the sale of more than 13 million units of electric vehicles during 2025. The sector exported around 1.2 million cars in the same period, focusing on the Europa and Ásia markets. The balance between high engine speed and road safety is part of a broader government goal. National strategic planning seeks to reduce the total number of traffic accidents in cities by 15% by the year 2027.
