Report: Porsche CEO to Take Over From Diess at VW Brand Share Comments As part of continued shakeups at the Volkswagen Group, the Porsche CEO Oliver Blume will be promoted to head of the Volkswagen Brand. He will take over from Herbert Diess, whose position as head of the Group remains secure. The decision was made to help handle production issues that have plagued the ID.3 and Golf 8, reports Germany’s Auto Motor und Sport, citing unnamed sources. Bernhard Maier, the current head of Skoda, will replace Blume at Porsche. Before leading Skoda, Maier was head of sales at Porsche. It is still unclear when all of these title changes will take place.
