Opel’s Works Council in Germany has asked parent General Motors for clarification regarding potential sale rumours.

Speculation has been rife that GM is mulling a possible sale of its European arm, although Opel chairman Nick Reilly insisted last week the American owners were “very satisfied” with progress.

“We asked Opel that they should say there will be no selling of Opel, but they can’t say so clear[ly] like we wanted,” a Works Council source in Germany told just-auto.

“We asked them also ‘ask Detroit’ to give us a statement and they said because of the SEC [Securities and Exchange Commission] rules, they can’t say anything for or against.”

Rumours the US manufacturer was mulling a possible Opel sale came to light last month, although German reports indicated GM CEO Dan Akerson had told his European arm there were no discussions to sell. 

“Opel/Vauxhall is important for GM because we are the European brand of GM, not Chevrolet,” said the Works Council source. “We have got the technology for all the mid-class cars.

“They need us – they are just silent.”

GM Europe posted a profit in Europe during the first quarter and Opel increased monthly market share for the seventh month in a row on a year-on-year basis, Reilly noted last week.

Opel was not immediately available for comment.
