Does the Corolla Meet China 6 Emission Standards?
2 Answers
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.
I've been driving a Corolla for several years, and this car truly complies with China's latest National VI emission standards, especially the newer models in recent years. The National VI standard is China's newest environmental requirement, significantly stricter than previous regulations, primarily targeting tailpipe pollutants like nitrogen oxides and particulate matter. The Corolla uses Toyota's high-efficiency engines, all certified through pre-delivery testing. When I purchased the car, the paperwork from the 4S dealership clearly stated it met National VI-B standards. This gives me much more peace of mind while driving, as urban enforcement is strict nowadays - National VI-compliant vehicles can be registered smoothly without penalty. If you want to verify, just check the manufacturing date and environmental information on the vehicle's green certification. It's fuel-efficient and smooth to drive; I'd recommend buying a post-2020 model, which is absolutely compliant. Regular maintenance checks on the emission system are crucial—don't forget to review the manual details for more eco-friendly and worry-free usage.
