China's Ministry of Public Security has swiftly addressed a misunderstanding that sparked a heated online debate. The ministry confirmed that it is not imposing a blanket 5-second 0–100 km/h acceleration limit on vehicles, contrary to what some readers inferred from a draft safety standard. But here's the twist: the draft does include a 5-second rule, but it's not as restrictive as it first seemed.
The clause in question states that passenger vehicles must default to a mode where acceleration from 0 to 100 km/h takes at least five seconds after each power-on or ignition event. This rule, however, only applies to the initial start-up mode, not the vehicle's ultimate performance capabilities. And this is where it gets interesting: the draft allows for faster acceleration once drivers engage additional inputs or performance settings.
The clarification comes after the topic 'EV acceleration performance banned' went viral on social media, causing concern among car enthusiasts. The ministry's drafting official explained that the rule aims to address the challenges posed by the growing number of new-energy vehicles with strong initial torque, which can make controlling the vehicle from a standstill more difficult for some drivers. This is particularly relevant for EVs, which have seen a rise in incidents involving loss of control during start-up.
Interestingly, several popular Chinese EV models already achieve sub-five-second acceleration times, such as the Xiaomi SU7 Max (0–100 km/h in 2.78 seconds), BYD Han L EV (2.7 seconds), and Geely Galaxy E8 (3.49 seconds). These examples prove that the draft's regulation focuses on start-up torque delivery, not limiting the vehicle's overall performance.
The draft also introduces other safety measures for new-energy vehicles, including standardized regenerative braking systems, deceleration limits, and mandatory pedal-misapplication suppression systems. These additions aim to enhance driver control and safety, especially in stop-and-go traffic situations.
As the draft undergoes public consultation, it's clear that China is taking a nuanced approach to vehicle safety regulations, balancing innovation and performance with the need for safer roads. And this is the part most people miss: the draft's focus on start-up behavior could set a precedent for future regulations, sparking further debate on the balance between performance and safety in the automotive industry.
