FRANKFURT - Volkswagen said on Friday it would stop production of its flagship Golf model at its main Wolfsburg plant next week if the strikes in eastern Germany continue.
"If the strike continues, the Golf production lines will come to a halt," said a VW spokesman, adding that output of the small Lupo car also may be hit.
German engineering union IG Metall members are striking over the length of the working week in eastern Germany, and the action has stopped production at some important auto suppliers in Brandenburg, Berlin and Saxony.
Munich-based carmaker BMW AG warned on Wednesday of possible production bottlenecks next week if the strike action in eastern Germany, now in its 18th day, continued to affect suppliers.
DaimlerChrysler said it was trying to maintain normal production.
"Our west German plants are currently not affected by the strike. We are trying to maintain production and we are fairly confident that this will work out," a spokeswoman said.
Some 11,000 workers downed tools in east Berlin, Brandenburg and Saxony on Thursday as IG Metall, Germany's biggest union, fights to cut the working week for east German engineering employees by three hours to the west German standard of 35 hours.
