News agency Reuters is reporting Porsche's CEO Matthias Müller will be appointed as Martin Winterkorn's successor.

The official announcement will be made tomorrow following the Supervisory Board meeting within the Volkswagen Group. At the same meeting, it is believed Audi's research and development boss Ulrich Hackenberg along with Porsche's engine chief Wolfgang Hatz will be forced to announce their resignation while Volkswagen of America's chief executive Michael Horn is going to be replaced by current Skoda chief Winfried Vahland.

All of these changes at the top of the corporate ladder are a consequence of the so-called "dieselgate" involving a special device installed on the Type EA 189 2.0-liter turbodiesel engines to manipulate emissions tests. Volkswagen says they have allocated €6.5 billion to fix around 11 million cars that have this cheating gimmick and also to pay the upcoming fines.

A new report states Volkswagen has installed a similar device on the smaller 1.6 TDI engine as well, but we don't have a confirmation at this point. Moreover, the Environmental Protection Agency (EPA) in United States has already started investigating the V6 3.0-liter turbodiesel available on a variety of larger models from the VAG empire.
