(ANSA) - Rome, July 27 - Volkswagen has demanded that Fiat CEO Sergio Marchionne quit as the president of European auto industry association ACEA after blaming the German company for creating a "bloodbath" in the car market with its aggressive pricing policy. VW also said it was thinking about leaving the ACEA in protest. "Mr. Marchionne is unbearable as president of ACEA. We call for him to resign," VW's head of corporate communication, Stephan Gruehsem, told the Wall Street Journal. Fiat has been hit hard by the crisis of the European car market. Its car sales in Europe dropped 16.7% in June taking its share of the European market to 6.4%, compared to 7.5% in June 2011. Marchionne said earlier this month that the carmaker may have to close one of its plants in Italy if weak demand on the European auto market continues.
