Volkswagen Group has delayed the U.S. launch of its flagship Arteon sedan for a few more months as it waits for that all-important emissions certification. Apparently, Europe’s switch to the updated Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP) has created an extensive approvals backlog.

While the United States still uses the EPA’s less forgiving FTP-75 and HWFET, Europe is in the process of abandoning the ironically named New European Driving Cycle (NEDC) for WLTP. Presumably, VW wants to ensure its vehicles are green lit by the EU before it starts manufacturing them for the U.S. Unfortunately for the automaker, it stands to lose sales in the interim.
