Chinese regulators have introduced a new national standard designated as GB 21670–2025, which addresses various regulations related to electric and electrified vehicles. Effective in phases, the most notable change is the prohibition of one-pedal driving as a factory default setting, starting January 1, 2027. This decision does not eliminate the feature entirely; drivers will still have the option to engage one-pedal driving if their vehicle is equipped with it.
To understand the implications of this regulation, it is essential to clarify what one-pedal driving entails. This driving mode allows the operator to control the speed of an electric vehicle (EV) using solely the accelerator pedal. By easing off the accelerator, the vehicle employs its regenerative braking system to slow down, converting kinetic energy back into stored energy in the battery rather than dissipating it as heat, which is typical in conventional braking systems. This capability not only enhances energy efficiency but also extends the vehicle’s range.
The decision to not set one-pedal driving as the default acknowledges that not all drivers may be familiar with the feature or its operation. While this driving style is appealing to many EV users due to its efficiency, studies have suggested that reliance on strong regenerative braking could lead some drivers to delay traditional braking in critical situations. This concern mirrors advancements made by manufacturers like Porsche, which has integrated its regenerative braking technology into the brake pedal of its Taycan model, promoting smoother transitions between regenerative and friction braking.
Implementation Timeline and Additional Requirements
Although the primary regulation concerning one-pedal driving will not take effect until 2027, some aspects will be implemented sooner. Beginning on January 1, 2026, new electric vehicles that utilize regenerative braking at rates exceeding 1.3 m/s² will be required to activate their brake lights. This measure aims to improve safety by alerting other drivers when vehicles are decelerating rapidly.
Another critical provision of the new regulations mandates that all electric vehicles produced in China must include an anti-lock braking system (ABS). This technology is designed to prevent skidding during emergency braking, allowing drivers greater control and shorter stopping distances. The overall benefits of incorporating ABS include a reduction in accidents and potential lower insurance premiums for drivers.
As the automotive landscape continues to evolve with the rise of electric vehicles, regulations such as these reflect a growing awareness of safety and driver education. While the transition to more sustainable driving practices is vital, ensuring that drivers fully understand the technologies at their disposal remains a priority for regulators in China and beyond.
