Former CEO Martin Winterkorn resigned Wednesday, and the automaker has promised more personnel will face consequences for the developing dirty diesel scandal. For using secret software on its TDI models to trick emissions equipment, Volkswagen AG faces as much as $18 billion in fines in the United States alone.

In addition to the leadership shakeup, VW's overarching Supervisory Board has announced a restructuring that touches every area of the organization. Along with the creation of a new North American region—encompassing the United States, Mexico, and Canada—and some high-level Supervisory Board management shifts, the most notable change will be the end of a production role on the board. That responsibility will transfer to individual brands, and the move is designed to make individual regions more accountable for their vehicles.
