Core Viewpoint - The new national standard for passenger car braking systems, effective from January 1, 2026, aims to enhance safety and standardize the use of single-pedal driving mode, which has been a topic of debate in the automotive industry since its inception [1][2][3]. Group 1: New National Standard Details - The new standard, GB21670-2025, is the first major update since 2008 and regulates the single-pedal mode, stating that vehicles must not decelerate to a stop solely by releasing the accelerator pedal [1]. - The standard specifies that if a regenerative braking system has multiple operating states, it must revert to a default state upon powering on, with a maximum deceleration of 3 m/s² in default mode [2]. - Manufacturers are required to inform users about the settings for the operating states through user manuals or electronic records, and visual signals must be provided when the braking force exceeds 1.3 m/s² [2]. Group 2: Industry Implications - The introduction of the new standard is seen as a safety measure that guides the safe use of single-pedal mode and encourages innovation within reasonable limits [2]. - The standard aims to unify the functionality, activation conditions, and user prompts for single-pedal mode, addressing inconsistencies that could affect driving safety and user experience [4]. - The standardization may lead to increased cost pressures for component suppliers, as automakers may push for lower prices, intensifying competition and potentially accelerating industry consolidation [6].
