Volkswagen has threatened to leave the ACEA European car makers association in response to comments by Fiat boss Sergio Marchionne over rising tensions and falling sales in the industry as sales slump.
According to a New York Times report published at the weekend, Marchionne suggested VW's pricing strategy was creating a "bloodbath".
It said that executives, including Marchionne, also ACEA's president, accuse the German carmaker of exploiting the debt crisis to expand its market share.
The comments "show once again that Marchionne is not qualified to be ACEA president", VW spokesman, Stephan Gruehsem said, calling for his resignation. VW is also considering leaving the association itself, he said. The spat highlights the strained relationships in the European auto industry.
VW has reported record first-half profits, while Fiat and PSA Peugeot Citroen contend with rising European losses.
