Volkswagen CEO Oliver Blume is aiming to carry out the biggest overhaul in the automaker’s history, according to Manager Magazin. The plan reportedly targets cuts of up to 100,000 jobs across the group over the coming years and includes the potential closure of four plants in Germany.

The report also says Volkswagen may reduce planned investment by about 15% to just over €130 billion over the next five years. Blume and CFO Arno Antlitz are described as pursuing a fundamental redesign of the company structure, including spinning off the core VW brand and the parts-manufacturing operations into separate entities.

Manager Magazin further reports that production would be slated to stop at plants in Hanover, Zwickau, and Emden, as well as at Audi’s Neckarsulm site, but only once current vehicle models are phased out. The proposals would extend beyond an existing programme previously discussed as cutting around 50,000 jobs.

The report notes that Blume has faced pressure to improve performance as Volkswagen deals with multiple challenges, including tariffs, competition—particularly from Chinese automakers—and the high costs and pace of the shift to electric vehicles. A Volkswagen spokesperson declined to comment on confidential documents, saying decisions would be handled through the company’s governing bodies.

Germany’s powerful works council and the IG Metall union warned they would resist the measures if they proceed, and said they would do everything in their power to prevent them
