PARIS (Reuters) - Volkswagen Group
Registrations fell to 1.12 million cars in European Union and European Free Trade Association (EFTA) countries last month from 1.47 million in September 2017, Brussels-based ACEA said.
Volkswagen Group sales fell by 47.8 percent, Fiat Chrysler by 31.4 percent and Renault by 26.9 percent, according to the data. The French carmaker's alliance partner Nissan <7201.T> also recorded a 43.8 percent decline.
The new Worldwide Harmonised Light Vehicle Test (WLTP) became mandatory on Sept. 1, forcing some carmakers to halt deliveries of some models that had yet to be re-certified.
VW, Renault and Fiat Chrysler had led a sales surge in August, as carmakers boosted discounts and registrations of their own vehicles to be sold as nearly new on the used car market.
