How to Determine Whether a Car is China 5 or China 6 Standard?

[VonLila]

Methods to determine whether a car is China 5 or China 6 standard: The China 5 or China 6 labels are not displayed on the vehicle itself but can be identified through the data on the vehicle acceptance certificate, where China 5 is represented as Ⅴ and China 6 as Ⅵ in Roman numerals. China 5 and China 6 refer to the national standards for vehicle exhaust emissions. The higher the number, the more environmentally friendly the vehicle's exhaust emissions are, with China 1 being the most polluting and China 6 the least. The China 6 emission standard is an upgraded version of the current China 5 standard, imposing stricter and more scientific requirements on vehicle exhaust pollutants. Compared to the existing China 5 standard, the China 6 standard features significant optimizations in multiple aspects, enabling a more comprehensive and objective assessment of vehicle emission levels while being easier to implement and regulate.
