What is the emission standard of the Besturn X40?
2 Answers
The Besturn X40 has some models on sale that have passed the China 6 emission standard certification. China 6 Standard: The China 6 standard, also known as the "National Sixth Stage Emission Standards for Motor Vehicles," imposes stricter limits on pollutant emissions compared to the China 5 standard. Increased Fuel Consumption: The China 6 emission standard is significantly stricter than the China 5 standard, requiring the installation of a more robust filtration system in the three-way catalytic converter. While the enhanced filtration system effectively reduces pollutant emissions, the denser filtration system inevitably impacts exhaust efficiency, potentially causing poor engine exhaust flow and a certain increase in fuel consumption.
I've been repairing cars for over a decade and have worked on many Bestune X40 models. I can tell you that early production versions mainly met the China 5 emission standards. China 5 refers to the fifth phase of China's vehicle emission regulations, which had relatively lenient exhaust control requirements for both diesel and gasoline vehicles, allowing higher emissions of pollutants like nitrogen oxides. Typically, Bestune X40 models produced before 2017 or 2018 complied with this standard - you'll need to check the vehicle's nameplate or manual to confirm specifics. If the car was manufactured after 2019, it would have been upgraded to the stricter, more environmentally friendly China 6 standard. From my maintenance experience, I recommend regular exhaust emission testing and using appropriate engine oil to reduce pollutant buildup, preventing annual inspection failures. When buying a used Bestune X40, try to choose a China 6 compliant version as they'll face fewer driving restrictions in major cities. Ultimately, emission standards directly impact air quality and ownership costs - don't underestimate their importance.
