General Motors co. says the head of Germany's Opel unit will take over all operations in Europe on January 1, the latest move by U.S. automakers to speed up the turnaround in the troubled region.
Mr. Reilly had previously led Opel but he was replaced by Mr. Stracke on the job in April.
Since 1999, GM has lost more than $ 13 billion on Opel, despite some efforts of restructuring. The company has reached a deal to sell Opel in 2010 after a reorganization in Bankruptcy Court, but withdrew at the eleventh hour. Last year, the Chief Executive And has been pushing for Akerson faster progress in turning around Opel Vauxhall brand, and the project. His impatience caused Mr. Stracke took over Opel unit from Mr. Reilly, people familiar with the matter said.
