Ripplewood Holdings LLC is interested in investing in troubled Mitsubishi Motors Corp., according to sources.

MMC has been trying to muster capital from would-be investors in the aftermath of a decision by its top shareholder, DaimlerChrysler AG, not to inject it with additional capital.

The U.S. investment fund appears to be considering funneling some 100 billion yen into the capital base of the ailing Japanese automaker, the sources said Wednesday.
