Talks with Nissan to restart???? - NEW YORK/DETROIT (Reuters) - A deal to merge General Motors Corp (GM.N: Quote, Profile, Research, Stock Buzz) and Chrysler LLC has hit an impasse after the Bush administration ruled out funding for it, three people with direct knowledge of the talks said. This puts any merger of the struggling automakers on hold until after the U.S. presidential election, the sources said. The development adds a new element of uncertainty for the embattled U.S. auto industry as Detroit's political allies warn the sector faces a deepening financial crisis that threatens tens of thousands of jobs. It also opens the door for Cerberus Capital Management, which owns Chrysler, to restart talks with the Nissan-Renault alliance run by Carlos Ghosn. The private equity firm has seen that option as a backstop to an outright acquisition of Chrysler by GM, one of the sources said. The sources declined to be named as they were not authorized to discuss the private talks. GM and Cerberus declined comment. This week, Ghosn said he sees any deals among automakers involving a cash element as unlikely unless the cash came from outside, such as from the government. Discussions with Nissan-Renault (7201.T: Quote, Profile, Research, Stock Buzz) (RENA.PA: Quote, Profile, Research, Stock Buzz) would likely start with consideration of an expanded product-based tie-up building on an existing deal between Chrysler and Nissan, the source familiar with those talks said. A merged GM-Chrysler would be the largest automaker by sales, but analysts have cautioned it would struggle to turn around the overlapping Detroit-based operations of two firms that have seen mounting losses tied to a global downturn. Chrysler, which has seen its sales fall 25 percent this year, said it was moving ahead with a cost-cutting plan and with plans for new vehicles, including a plug-in hybrid. "We are taking the tough but necessary decisions to stabilize the business in the short-term and making the viable long-term business decisions to restructure the company for the future," Chrysler spokeswoman Lori McTavish said. GM and Cerberus have been in talks since September, according to sources. GM had approached the U.S. Treasury in recent days about support for the merger through some $10 billion in new funding that would have included taking an ownership stake in the merged company, people familiar with the talks have said. TREASURY STAYS AWAY But a Bush administration official said on Thursday the Treasury Department was not negotiating direct aid for the merger. Instead, the official told Reuters, the administration was working to speed the distribution of $25 billion in low-cost loans for automakers to retool factories, a move that was authorized by Congress last month.
