General Motors Corp is speeding up preparations for a possible bankruptcy filing even as directors scout for deeper savings this week to avoid that outcome, people familiar with the plans said.

GM would focus on forming a new company from its best assets if court protection is needed, said the people, who asked not to be named because the details aren't public. The efforts to set a new cost-cut goal center on how to go beyond a proposal to slash debt by 46 percent and shed 47,000 jobs in 2009, and will include talks with Treasury officials, the people said.

The moves are a response to President Barack Obama's March 30 rejection of GM's bid to keep $13.4 billion in federal loans. With bondholders and the United Auto Workers balking at concessions, a push for more savings makes bankruptcy more "probable," Chief Executive Officer Fritz Henderson has said.
