What is the emission standard for VI?

[StCamille]

VI is the China VI emission standard. When the China VI emission standard was introduced, the country clearly defined the phased implementation of two modes: China VI a and China VI b. Among them, China VI a is equivalent to the transition stage from China V to China VI, while China VI b is the true China VI standard emission. The China VI standard has stricter limit requirements, which are 40% to 50% stricter than those of China V. In addition, unlike the different limits for gasoline and diesel vehicles in the China V stage, the China VI standard adopts the same limit requirements for gasoline and diesel vehicles based on the principle of fuel neutrality. The China VI standard adds requirements for the emission warranty period, stipulating that if there are failures or damages related to emissions within 3 years or 60,000 kilometers, leading to excessive emissions, the automobile manufacturer shall bear all costs for corresponding repairs and replacement of parts to protect the rights and interests of car owners.
