Great Wall Motor publicly reported that two BYD models used atmospheric fuel tanks, and that the emissions of evaporative pollutants from the entire vehicle did not meet the standards.
BYD responded that the tested vehicles sent by Great Wall Motor to China Automotive Technology and Research Center (CATARC) in Tianjin did not meet the inspection status under the national standard, and its inspection report was considered invalid. Some media called departments of the CATARC for further information.
An employee of the General Management Department said: "This issue will be answered by the group.”
Later, it was learned from the relevant staff of CATARC that the institution is investigating and dealing with the issue.
