May 2017 is compliant with China 5 emission standards. Below are the relevant details: 1. China 5 emission standards: Carbon monoxide emissions must not exceed 1000mg/km; Non-methane hydrocarbons must not exceed 68mg/km; Nitrogen oxides must not exceed 60mg/km; PM fine particles must not exceed 4.5mg/km; PN fine particles must not exceed 6x10^11mg/km. 2. China 6B emission standards: Carbon monoxide emissions for gasoline vehicles must not exceed 500mg/km; Non-methane hydrocarbons must not exceed 35mg/km; Nitrogen oxides must not exceed 35mg/km; PM fine particles must not exceed 3mg/km; PN fine particles must not exceed 6x10^11mg/km.
Oh, for cars in May 2017, they were definitely China V emission standards. I remember clearly, starting from January 1, 2017, all new cars nationwide had to comply with the China V standard. China V represents the National Stage 5 emission requirements, which are stricter than the previous China IV, significantly reducing many air pollutants. If you're asking about new cars purchased around that time with a manufacturing date after 2017, they absolutely met the standard. China V vehicles are more advanced in engine design and emission control, and even after several years of use, they perform well and are more environmentally friendly for urban areas. If you have the vehicle information on hand, check the environmental label or registration certificate—it will show a 'V' for China V standard. Don’t forget, the upgrade in emission standards is for environmental protection. In May 2017, it was still the peak period for China V, before China VI, so no need to worry.
Having worked in the auto repair shop for a long time, I must say that cars manufactured in May 2017 must comply with China V emission standards. Starting from January 2017, all newly produced gasoline and diesel vehicles implemented the China V standard. You just need to check the 10th digit of the vehicle's nameplate or VIN code – if it's the letter H, it means the car was made in 2017, which is a China V model. Emission standards are important; China V vehicles have fewer fault light issues, and maintenance costs don't change much. If you're buying used, have a repair shop test the exhaust or check the environmental records. The policy transition period was short, so cars from that time were basically compliant. Don't believe claims that they might be China IV – those from official channels are all China V.
