Swedish Automobile, which owns Saab, is in "real and substantive" talks with potential investors, according to the automaker's North American president and reported by Reuters.

"There are talks going on ... real and substantive talks," Tim Colbeck said.

Last week, a Swedish business daily reported that a big American investor was planning to go in as a part owner in Saab. The company declined to comment on the article.

Fears over the survival of Saab, rescued from closure early last year, have ebbed and flowed as Swedish Automobile chases funding. Its production line has been closed since late April. Saab staved off a fresh bankruptcy threat on Aug. 5 by finding money to pay its workers.
