When were the vehicles compliant with China V emission standards produced?

China V emission standards were first implemented in Beijing starting from February 1, 2013, making it the first city in China to adopt the fifth-stage vehicle emission standards. From January 1, 2017, nationwide supply of gasoline and diesel meeting the China V national standards began, and fuels below the China V standard were discontinued for domestic sales. The emission control level of China V standards is equivalent to the fifth-stage emission standards currently in effect in Europe. Compared to China IV standards, China V standards reduce nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. Additional Information: 1. The fifth-stage national vehicle pollutant emission standards, abbreviated as "China V standards," have an emission control level equivalent to the fifth-stage emission standards currently in effect in Europe. The European Union has been implementing these standards since 2009, which impose stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Each upgrade from China I to China IV has reduced single-vehicle pollution by 30% to 50%. 2. It is reported that starting from February 1, 2013, Beijing became the first city in China to implement the fifth-stage vehicle emission standards. From March 1, the sale and registration of non-compliant light-duty gasoline vehicles were halted. Subsequently, Shanghai, Jiangsu, Guangdong, Shaanxi, Zhejiang, Tianjin, and other regions successively entered the "China V" era. After the upgrade, the sulfur content in China V gasoline will be 80% lower than that in China IV standards, while the diesel quality will leap from China III to China V, with sulfur content reduced by 97%. Additionally, the manganese and olefin content in China V gasoline will be correspondingly reduced, improving fuel performance and leading to varying degrees of improvement in vehicle emission indicators.
I noticed that China's National V emission standard vehicles roughly started from 2017, when I first began following the automotive industry's development. I remember after the new regulations were introduced, automakers quickly upgraded their technologies to reduce pollution. Major cities like Beijing implemented it even earlier, possibly with some models meeting the standards as early as 2016, but nationwide enforcement began on January 1, 2017. New vehicles produced after this period, such as those from 2017 to 2019, generally complied with National V, strictly controlling pollutants like nitrogen oxides, making them more environmentally friendly than the National IV standard. When buyers look for used cars, if they see a 2017 model, there's a high chance it meets National V. However, the transition period was short, jumping to National VI by 2020, so National V vehicles didn't last long. Still, they significantly influenced purchasing decisions, with many preferring them to comply with urban environmental policies.
