BERLIN -- Labor leaders at Audi have asked top management to assign production of an all-electric model to the carmaker's main Ingolstadt plant in Germany.
Unions are concerned that Audi's German workers might lose out as electric cars gain in importance.
Audi will next year start building its first mass-produced electric model, the e-tron quattro SUV, at a plant in Brussels, together with batteries that will also be used in other Volkswagen Group electric vehicles.
VW's main profit contributor plans to launch three all-electric models by 2020 and workers at Audi's main plant in Ingolstadt don't want to be left behind in the race for production.
"Our core factory must be prepared further for the future," Audi's top labor representative, Peter Mosch, told a gathering of 7,000 workers on Wednesday at the Ingolstadt plant which employs about 43,000 people.
"None of our colleagues must fall off the conveyer belt as we move into the future," deputy works council chief Max Waecker said.
Audi CEO Rupert Stadler has previously said the automaker's smaller German plant in Neckarsulm where 16,000 workers assemble the high-end A6, A7 and A8 models, will start making battery-only vehicles from about 2020.
Mosch, who sits on VW's supervisory board, asked top management to provide specific information as to how the growing shift to electric cars and digital services will affect employment at Audi, which has 88,000 workers globally.
Audi has previously been reluctant to embrace all-electric drive technology but the success of Tesla and the establishment of rival BMW's "i" subbrand of electric cars has convinced Audi there is a market for electric luxury vehicles after all.
Daimler, another rival, said on Wednesday it was planning to accelerate its electric car program.
Audi's e-tron quattro, powered by three electric engines, is expected to run for over 500 km (311 miles) per charge based on a 95-kWh battery pack that can be fully recharged in about 50 minutes.
