Europe's biggest carmaker has been working on a new strategy for its core autos business that it hopes will boost its profitability once it emerges from an emissions test-rigging scandal which plunged the carmaker into a 4.1 billion euro operating loss for 2015.

"We want to lead Volkswagen out of the company's most difficult situation ever and shape it into a mobility provider," Mueller said in a speech given to the auto maker's senior managers, the copy of the speech showed.

In his presentation, Mueller said that the new strategy will be presented in mid-June.
