Can a China 5 vehicle be upgraded to China 6 emission standards?

[DiNova]

Individuals cannot upgrade their China 5 vehicles to China 6 standards on their own. Differences in emission standards: China 6 is much stricter than China 5. According to the "2017 Air Pollution Prevention and Control Work Plan" by the Ministry of Environmental Protection, China 6 standards are 40% stricter than China 5 in terms of carbon monoxide, PM fine particulate matter, and benzene content in gasoline. Targeted groups differ: China 6 mainly targets automobile manufacturers, focusing on production consistency checks, new vehicle inspections, and in-use vehicle compliance checks. This increases scrutiny on manufacturers to ensure they produce vehicles that meet national emission standards. Cost differences: Manufacturing vehicles that comply with China 6 standards increases costs for automobile manufacturers. For example, adding PDF (Particulate Diesel Filter) and particulate traps to engines ultimately leads to higher costs for consumers.
