There is no specific data available as the implementation timeline of emission standards varies by region. In areas with slower adoption rates, China National V compliant vehicles were introduced much later. Introduction to China National V standard: The China National V standard is equivalent to the Euro V standard implemented by the European Union since 2009. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Latest national standard: The fifth phase of China's national vehicle emission standards will be implemented nationwide starting January 1, 2018. Beijing will implement the fifth phase ahead of schedule, starting January 1, 2016.

I've been in the automotive industry for years and have a deep understanding of emission standard changes. The China V standard is the fifth-phase environmental requirement implemented in China in 2017. For the Teana model, vehicles manufactured from around 2017 onwards generally comply with China V emissions. Specifically, the sixth-generation Teana was produced from 2013 to 2018, with versions after 2017 upgraded to China V. The 2016 models might still be China IV, but all post-2017 versions consistently meet the standard. Emission upgrades mean optimized engine tuning to reduce pollutants like carbon monoxide emissions, benefiting vehicle inspections and environmental ratings. When checking a vehicle, look at the production date on the chassis nameplate or confirm via the vehicle registration certificate. China V-compliant cars are more favored in urban driving restrictions, making 2017-2018 used Teanas a cost-effective and eco-friendly choice.

As an average car owner, emissions are an important consideration when choosing a vehicle. The Nissan Teana models meeting China's National V emission standards generally started from the 2017 model year. I remember my friend bought a sixth-generation Teana in 2018, and the emission compliance was clearly marked on the environmental label. The National V standard was fully implemented in 2017, meaning vehicles produced in 2017 and later all comply. Checking is straightforward—just look at the manufacturing date on the door frame nameplate. National V vehicles pass tailpipe emissions tests more easily, saving you the hassle during inspections. Non-compliant emissions might affect ownership transfers, so it's safer to buy models from 2017 onward. Other models like the Camry follow similar patterns—higher emissions standards indicate newer technology, making long-distance driving more reassuring.

Speaking of automotive history, the China 5 emission standard was implemented in China in 2017. In the Teana series, vehicles produced from 2017 onwards adopted the China 5 standard. The sixth-generation models continued until 2018, with all post-2017 vehicles meeting the standard. Some 2016 models partially complied with transitional standards. The emission upgrade responded to environmental policies to reduce air pollution. Checking the vehicle's production year reveals its emission level. Choosing post-2017 vehicles ensures greater reliability.

I pay attention to emission details during the car purchasing process. The Nissan Teana's China 5 version appeared starting from the 2017 models. When purchasing a sixth-generation car manufactured in 2017, the environmental protection label showed China 5. The China 5 standard reduces harmful exhaust emissions, resulting in a high one-time pass rate during vehicle inspections. It is recommended to check the manufacturing date or the certificate of conformity. High emission standards make daily driving more environmentally friendly and worry-free.
