Automakers BYD and Great Wall Motor fight dirty over emissions claim

Electric vehicle makers BYD and Great Wall Motor are locked in an open fight that started after the latter filed a report with the Chinese regulators alleging that BYD’s two top-selling hybrid models did not meet emissions standards.

China’s Great Wall Motor reported to the ecology and environment ministry, the industry and information ministry and the top market regulator that BYD failed to meet pollutant emissions standards in two hybrids.

BYD said in response that its products were compliant with China’s standards

Reuters reports that Great Wall Motor accused BYD of using non-pressurised fuel tanks in its Qin Plus and Song Plus plug-in hybrids, which let the liquid inside evaporate more than in high-pressure tanks.

Great Wall Motor did not provide any evidence for its allegations.
