China is set to introduce new regulations that will reshape how regenerative braking systems operate in electric vehicles (EVs), a move likely to impact the growing segment of drivers who favour one-pedal driving. The new rule, outlined under the national standard GB 21670-2025, is scheduled to come into effect on 1 January 2027.
This legislation will prohibit EVs from having a default driving mode that brings the car to a complete stop simply by releasing the accelerator pedal. While the rule does not entirely ban one-pedal functionality, it requires that such features no longer be the vehicle’s default setting. The change appears to be aimed more at enhancing road safety than improving battery efficiency.
According to a report by The Paper, a Chinese news outlet, the primary concern behind the new regulation is the delayed braking response observed in drivers accustomed to strong regenerative braking. Studies have indicated that drivers relying heavily on regenerative deceleration may hesitate to apply the brake pedal in emergency situations—where the stopping power provided by regenerative systems alone proves insufficient. This delay could compromise reaction times, especially in critical moments requiring full braking force.
