Tesla's new factory near Berlin is set to ramp up production.
It could soon be making up to 10,000 electric vehicles per week.
And that could spell trouble for workers at Volkswagen.
On Wednesday (October 12) the German giant said it was accelerating plans to transform its main plant to produce EVs.
But electric cars require far fewer parts than traditional autos, and thus far fewer workers.
Germany's Handelsblatt newspaper says VW could shed 30,000 jobs as a result.
It says the figure was mentioned by company chief Herbert Diess at a September board meeting.
VW would only say that many scenarios are under consideration.
A spokesman for the company's workers' council called the reported figure 'absurd and baseless'.
VW's Wolfsburg car plant is the world's biggest, with 50,000 workers.
It doesn't currently make EVs, but will from 2026.
And big changes look certain, with Tesla and other new entrants proving much more efficient.
VW currently takes 30 hours to produce one of its electric ID.3 cars.
Tesla can make a Model 3 in just 10 hours.
