What is the emission standard of the 2017 Corolla?

[MacJoseph]

2017 Corolla complies with China National V emission standard. Here is some information about the China National V standard: 1. China National V standard is equivalent to the Euro 5 standard implemented by the EU since 2009, which imposes stricter limits on vehicle emissions such as nitrogen oxides and hydrocarbons. Each upgrade from National I to National IV reduces single-vehicle pollution by 30% to 50%. 2. The implementation of "China National V standard" will significantly reduce vehicle pollutant emissions. New vehicles will see 25% and 80% reductions in nitrogen oxides and particulate matter emissions respectively, while in-use vehicles will achieve an overall reduction of 10% to 15%. Additionally, it prohibits the artificial addition of manganese-containing additives, which helps protect key automotive components and reduces environmental pollution.
