Does the Corolla Meet China 6 Emission Standards?

[Danielle]

Starting from the 2019 model, the Toyota Corolla has been compliant with the China 6 emission standards. Differences in Limit Values Between China 6 and China 5 Standards: The China 6 standards impose approximately 40% to 50% stricter limit values compared to China 5. China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. In contrast, during the China 5 phase, diesel and gasoline vehicles had different emission standards. Differences Between China 6 and China 5 Emission Standards: Compared to China 5, China 6 reduces nitrogen oxides (NOx) by 77% and particulate matter (PM) by 67%. It introduces a limit requirement for particle number (PN) and imposes stricter regulations on emission control device durability and onboard diagnostic (OBD) system requirements. Purpose of Establishing China 6 Emission Standards: The China 6 emission standards specify the requirements for the sixth-stage type inspection of light-duty vehicle pollutant emissions, as well as the methods for checking and determining production conformity and in-use compliance. Manufacturers are obligated to ensure that the vehicles they produce and sell meet the in-use compliance requirements stipulated by the China 6 emission standards.
