BRUSSELS/FRANKFURT, June 30 (Reuters) - Efforts to save two leading European carmakers took a twist that could change the ownership of both crisis-hit General Motors Corp's GMGMQ.PK Opel and German sportscar maker Porsche (PSHG_p.DE).

As GM readied for a bankruptcy hearing in the United States, GM Europe said it was talking to other potential buyers for Opel as it worked through snags with preferred bidder Canadian-Austrian auto parts group Magna International (MGa.TO). [ID:nN29399207]

The potential buyers include Belgium-based holding company RHJ International (RHJI.BR) and Beijing Auto, a GM Europe spokesman said. Both companies have previously bid for Opel.

The Financial Times reported on Tuesday that RHJ was close to a deal to buy a stake in Opel. [ID:nLU10757]

In Germany, Porsche Automobil Holding SE (PSHG_p.DE) said it would seek alternative ways to finance its debt after state-controlled bank KFW [KFW.UL] officially rejected a 1.75 billion euro loan application. [ID:nLU480317]

Porsche has struggled to get loans to refinance a 9 billion euro debt mountain it ran up in the course of a botched takeover attempt of Europe's largest carmaker Volkswagen (VOWG.DE).

Porsche said on Monday that Qatar had made a written offer to the Porsche and Piech families that control the Porsche automotive holding. [ID:nLT10323] Qatar's offer could help the company cut its debt and ultimately clear the way for a merger between Porsche and Volkswagen (VOWG.DE).

Porsche and Volkswagen (VOWG.DE) have been in talks to create an "integrated" automotive group after Porsche's debt burden forced it to drop plans for a full takeover of VW.

RHJ-OPEL DEAL CLOSE?

Talks on a stake in Opel between its parent, GM, and Magna have been going on since Magna clinched an preliminary agreement just before GM's bankruptcy filing in May, pipping Fiat (FIA.MI) to the post at the time.
