Chinese regulators have introduced a new national standard, designated as GB 21670–2025, which will bring significant changes to the operation of electric and electrified vehicles. Starting January 1, 2027, the use of one-pedal driving will not be allowed as a factory default setting on new models. However, drivers will still retain the option to select and use this feature if their vehicles are equipped with it.
One-pedal driving allows drivers to control the speed of their vehicles using only the accelerator pedal. This method combines acceleration with regenerative braking, enabling the vehicle to slow down and come to a complete stop without the need to use the brake pedal. By easing off the accelerator, drivers engage the regenerative braking system, which recovers energy that would otherwise be lost as heat in traditional braking systems. This not only enhances the vehicle’s efficiency but also extends its range on a single charge.
The rationale behind the new regulations stems from concerns that drivers may become overly reliant on the strong regenerative braking feature. Studies indicate that this dependency could lead to delays in using the brake pedal during critical situations that require immediate stopping power. This precaution aligns with practices observed in vehicles like the Porsche Taycan, where regenerative braking is integrated into the brake pedal design, enhancing driver control.
Implementation Timeline and Safety Features
While the complete regulation will not take effect until 2027, some elements will be implemented sooner. Starting January 1, 2026, all new electric vehicles that utilize regenerative braking to decelerate at rates exceeding 1.3 m/s² must activate their brake lights. This measure aims to provide critical warnings to other drivers when vehicles employing one-pedal driving are slowing rapidly.
Additionally, the regulations mandate that all electric vehicles in China be equipped with an anti-lock braking system (ABS). This safety feature helps prevent skidding during emergency braking situations, enhancing grip and control for drivers. The implementation of ABS contributes to overall road safety, with studies showing it can significantly reduce the likelihood of accidents and lower insurance costs.
As the electric vehicle market continues to grow, these regulatory changes reflect a commitment to improve safety while also promoting technological advancements. By addressing potential issues related to driving habits, Chinese regulators aim to foster a safer environment for all road users.
