五问机动车新国标：为何要求百公里加速不小于5秒 影响哪些车？

Core Viewpoint - The new national standard for automotive safety aims to address the issue of acceleration-related loss of control in electric vehicles by mandating a default acceleration time of no less than 5 seconds for passenger cars upon startup [1][2][3]. Group 1: New Regulations - The draft standard requires that passenger cars, upon each ignition, must default to a state where the acceleration time to 100 km/h is no less than 5 seconds [1]. - Electric and plug-in hybrid vehicles must have a pedal misapplication suppression feature that detects and limits power output when the vehicle is stationary or creeping [1]. - The design of car door handles is also addressed, requiring mechanical release functionality to ensure doors can be opened in emergencies without tools [1]. Group 2: Rationale Behind the Regulations - The requirement for a minimum acceleration time of 5 seconds is intended to reduce the risk of accidents caused by inexperienced drivers misusing high acceleration modes [2][8]. - The standard is based on the observation that most driving schools and conventional fuel vehicles have acceleration times exceeding 5 seconds, making it a reasonable benchmark for new drivers [2]. Group 3: Impact on the Automotive Industry - The new regulations primarily affect high-performance four-wheel drive vehicles, while most two-wheel drive models are unlikely to require significant adjustments [9]. - Automakers can meet the new standards through software adjustments, such as modifying default power output and throttle response logic, rather than extensive hardware changes [9]. - The regulations are seen as a necessary step to balance safety and performance, especially as high-performance electric vehicles become more accessible to less experienced drivers [7][9]. Group 4: Industry Response and Future Outlook - The automotive industry is experiencing a shift towards higher safety standards in response to rapid technological advancements in electric vehicles [10][11]. - The new regulations are part of a broader trend to ensure that safety measures keep pace with innovations in vehicle technology, including smart driving and fast charging [10]. - The overall goal is to promote sustainable development in the electric vehicle sector by enhancing safety, regulating the market, and improving user experience [11].
