MUNICH (Reuters) - German carmaker BMW and Japanese rival Toyota Motor are planning to cooperate on research into lithium-ion batteries for electric cars, a source familiar with the situation told Reuters on Tuesday.
It was also reported over the weekend that the two were in talks for a partnership on 'green' vehicles, with BMW set to provide the Japanese firm with diesel engines.
The two companies are expected to announce the cooperation at a joint press conference at 0700 GMT on Thursday in Tokyo, the source said.
