DETROIT (AP) – General Motors’ talks with Renault and Nissan on a possible alliance – and reports Ford may be pursuing a megadeal, too – show how automakers constantly turn to each other even amid fierce industry competition.

GM and Ford declined to comment Monday on an Automotive News story that their high-level executives discussed a merger or alliance. Ford Motor Co. also declined comment on last month’s Wall Street Journal report that Ford proposed its own deal with Renault and Nissan.

In July, General Motors Corp., Renault SA of France and Nissan Motor Co. of Japan announced a 90-day review of a possible alliance among them.

Auto executives talk frequently about “what-if scenarios” and possible deals large and small, said David Cole, chairman of the Center for Automotive Research in Ann Arbor.

“These kind of discussions go on all the time,” Cole said. “Collaborating … is part of how they’re doing things.”

These talks have yielded a growing number of joint efforts on everything from hybrid vehicles to better automatic transmissions, he said.

GM and Ford have been slashing their work forces and closing plants in efforts to reverse multibillion-dollar losses in the face of tough competition from Asia-based automakers. On Friday, Ford announced deeper job cuts as part of its “Way Forward” restructuring plan.

GM lost $2.9 billion, or $5.19 per share in the first half of 2006, while Ford lost $1.3 billion, or 70 cents a share.

Both companies declined to comment on the Automotive News story that quoted several unidentified people who said senior GM and Ford executives had begun talks in July but that the talks are not taking place now.

“My job is to keep everybody focused on our Way Forward plan and accelerating our results,” Mark Fields, Ford’s president of the Americas, told The Associated Press on Monday. “If we discussed all the speculation that was out there, I think we’d probably spend a couple of days.”

GM spokesman Brian Akre said company officials “routinely discuss issues of mutual interest with other automakers.” He said such talks are private and “in many cases do not lead anywhere.”

Cole said an outright GM-Ford merger is unlikely and said that the companies carefully weigh antitrust issues during the lower-level cooperation that now takes place on such issues as hybrid vehicles, production technology and components.

“It would surprise me if there were a coming-together on the grand level,” said Cole, but said Ford and GM very well could start more joint efforts similar to their current work to develop a six-speed automatic transmission

Even if GM and Ford don’t merge, some other automakers will as the industry further consolidates, Cole said.

Ford’s chronic labor cost problems and its shortage of interesting models give GM little reason to seek a close alignment, said analyst Charles Fleetham of Project Innovations in Farmington Hills.

“I don’t see it from a business standpoint,” he said. “They have the same high health costs, high union costs, ineffective white collar work force that they want to get rid of.”

Ford shares fell 20 cents, or 2.5 percent, to close at $7.82 on the New York Stock Exchange, while GM shares fell 18 cents to $31.48.
