At a media - group interview held after the launch ceremony of the Haval H6L, Wei Jianjun, the Chairman of Great Wall Motors, shared his views on vehicle acceleration performance. He highlighted that cars with the ability to accelerate from 0 to 100 km/h in less than 4 seconds should come with specialized user training. This is because the extremely rapid acceleration of these vehicles can easily lead to dizziness in drivers, which in turn poses a threat to driving safety. Wei Jianjun stressed that in the context of daily driving, the acceleration performance from 0 to 40 km/h holds more significance. Moreover, he proposed the establishment of a new national standard. This standard would set a default upper - limit of over 5 seconds for the 0 - 100 km/h acceleration time of vehicles, aiming to mitigate the risks stemming from the improper operation of high - acceleration driving modes.
