The world's largest carmaker is creating its first all-electric plant and phasing out production of the internal combustion-engine cars built by generations of local workers.

The electric transformation raises questions about the long-term prospects of the auto industry, which employs 840,000 people in Germany and millions worldwide, as a source of jobs for communities like Zwickau, which gave the world both the luxury brand Audi and the communist-era Trabant "people's car."

Fewer workers will likely be needed, with different skills. And there is no mass market yet for battery-only cars. Volkswagen's 1.2 billion euros ($1.35 billion) investment is taken as a sign of hope for the community. But the longer term trends for employment across the industry are less certain.

"We see dangers in this, but we see this really as a chance for Zwickau the manufacturing center to stand out," the town's mayor, Pia Findeiss, told The Associated Press.

Over her desk hangs an oil painting from the communist period in the 1980s that shows the belching smokestacks from two coke plants that used to foul the city's air. Like the region's coal mines and textiles, that was an industry that came and went as times changed.

Among the key concerns is that electric cars don't need engines and transmissions with thousands of metal parts that need to be assembled. Where an internal combustion engine has 2,000 to 3,000 metal parts, an electric drivetrain has 150 to 250 parts. And the batteries that power it are produced through far different processes that are easy to hand over to robots.

The Frauenhofer Institute for Industrial Engineering in Stuttgart estimates that 23,000 to 97,000 German jobs could go missing in powertrain production by 2030. While that's only a fraction of the 44 million employed in Germany, the losses are likely to be concentrated in certain communities and companies, including suppliers.

Engine parts maker UKM Fahrzeugteile, for example, does half of its business in classic drivetrains. It says it's shifting its strategic focus toward trucks and motorcycles, as well as non-automotive fields like aviation.

"On a plant and regional basis, the effects can be serious," said Oliver Riedel, the institute's director. "Think about smaller businesses, for example, that are unable to make up for lost sales of components for internal combustion engines, or structurally weak regions where alternative employment is scarce."

At Zwickau, one assembly hall continues to turn out Volkswagen Golf hatchbacks with traditional engines, which help generate the profits to invest in developing electrics.

In a nearby hall, workers are preparing the future: they are setting up 350 massive orange robots that will turn out the ID 3, the affordable battery-driven car to be launched next year.
