The official statement that "a car accelerates from 100 kilometers to 100 kilometers in less than 5 seconds" is a misunderstanding: it just redefines safe starting.

3.3 seconds, 2.9 seconds, 1.9 seconds... the zero-to-100 acceleration record of new energy vehicles has been continuously refreshed in recent years. Models labeled as "performance monsters" are racing on city roads and highways. Once upon a time, accelerating from 0 to 100 mph in 5 seconds was an exclusive label for million-class supercars. Now it has become the "standard configuration" of new energy vehicles in the 200,000 yuan class, and some entry-level models also regard acceleration performance as a core selling point.

As this situation becomes more and more widespread, recently, according to the standard formulation and revision plan of the National Standardization Administration Committee, the Ministry of Public Security organized and completed the draft of the national standard "Technical Conditions for Motor Vehicle Operation Safety".

It mentions the speed limit requirement: every time a passenger car is started, it should be in a default state of not less than 5 seconds to accelerate to 100 kilometers (0-100km/h), and this has also caused huge controversy.

In response to the above situation, the relevant person in charge of the drafting working group on the technical conditions for motor vehicle operation safety said that there is a clear deviation in the general understanding of the outside world.

The person in charge emphasized that the "default working state" is the core of this clause, not "prohibition of acceleration within 5 seconds." This means that there is no written limit on whether a car can accelerate in 3 seconds, 4 seconds or even faster; what is regulated is only the way the vehicle releases power at the moment of starting.

Why is the default threshold set to 5 seconds?The person in charge explained that this is a result jointly reached by the drafting group and the National Technical Committee for Automobile Standardization based on the acceleration characteristics of market models and accident statistics.

Research shows that currently, in the existing market, the acceleration of most fuel-powered passenger cars from 100 kilometers to 100 kilometers is generally greater than 5 seconds. Drivers are more familiar with this performance range and are less prone to misoperation. Therefore, using it as the power benchmark in the startup phase is more in line with the control habits of mass users.
