There is big news from Volkswagen today with the announcement that supervisory board Chairman Ferdinand Piech has resigned on Saturday after losing a boardroom fight that he had provoked with Chief Executive Martin Winterkorn. Piech has been the major figure in VW for more than 20 years and has been the block to the company coming into Formula 1. The 78-year-old lost a 5-1 vote of the executive committee of the supervisory board last week. Deputy Chairman Berthold Huber will take over until a new chairman is picked. Piech’s wife, who was also on the supervisory board, has also quit.
