US hybrid carmaker Fisker Automotive is weighing several bids including a $350 million offer from Dongfeng Motor Corp that would give the Chinese carmaker majority control, said people with knowledge of negotiations.

Under the terms of its bid, Dongfeng would receive 85 percent of Fisker, said an insider who asked not to be named because the process is private.

"The company has received detailed proposals from multiple parties on different continents, which are now being evaluated by the company and its advisers," Roger Ormisher, a spokesman for Fisker, said in an e-mail. He declined to elaborate.
