GM is increasingly expected to file for Chapter 11 bankruptcy protection before the end of this month, after it emerged that the company had resistered the gmrestructuring.com and gm-restructuring.com web domain names.
The two web domains were registered last month and, although currently blank, are similarly named to sites Chrysler has used to put out information since it filed for bankruptcy protection.
General Motors has said it expects to file for bankruptcy protection if it cannot restructure its bond debt, cement concessions with its workers unions and show it can be viable ahead of a 1 June deadline from the US government.
If GM files for bankruptcy it is expected to pursue a quick sale of its best assets to a new operating company, similar to the process now being used by Chrysler.
Chrysler uses chryslerrestructuring.com for free access to certain court documents and details in that case.
News agency Reuters is also reporting that gmfiat.com was registered to an Italian address last week, although any deal between the two companies is expected to be restricted to GM Europe's Opel/Vauxhall operations.
