Volkswagen aims to cut costs by 20% by 2028 under a new restructuring plan.
Reports say plant closures are possible as the company adapts to tougher market conditions.
Chief executive Oliver Blume and finance chief Arno Antlitz outlined the savings strategy to senior managers.
The move responds to falling sales, high costs and growing competition from Chinese carmakers.
The group previously announced a €10bn restructuring that included 35,000 job cuts by 2030.
It says earlier measures already delivered savings in the double-digit billion-euro range.
Meanwhile, the EU trade deficit with China rose to €359bn in 2025.
German manufacturers remain deeply connected to the Chinese market despite rising tariffs.
Volkswagen has not confirmed specific measures but will provide further details with its annual results.
