If Mr. Piech is determined to oust Mr. Pischetsrieder , he will probably line up one of three candidates as a replacement : Wendelin Wiedeking , the chairman of Porsche ; Martin Winterkorn , the chairman of Volkswagen 's thriving Audi subsidiary ; or Wolfgang Bernhard , a former Chrysler executive recruited last year to turn around Volkswagen 's troubled flagship brand .
Wendelin Wiedeking /business/person/company Porsche
Martin Winterkorn /business/person/company Audi
