FRANKFURT/TOKYO (Reuters) - General Motors' shock decision to scrap the sale of its Opel unit, along with raised forecasts from Japan's Nissan Motor Co, indicates increasing confidence in the global auto industry's recovery.

But, in a major blow to Formula One motor racing, Toyota Motor Corp announced on Wednesday it was quitting the sport to further cut costs.

An unprecedented year of turmoil has reshaped the auto industry and those relying on it, but at least one major shake-up will now not go ahead.

After months of negotiations, General Motors has abandoned the sale of Opel to a group led by Canada's Magna, saying improving business conditions and the strategic importance of Opel had prompted the decision by its board.

It represented a setback for German Chancellor Angela Merkel, raised the risk of conflict with Opel's European unions and left open the question of how GM would finance its plan to go it alone by restructuring Opel.

Opel said the decision bought clarity for the group, which includes the Vauxhall brand.

"We will actively support all parties to implement this board decision as quickly as possible in order to safeguard a successful future for Opel," it said in a statement.

ON THE MEND

Automakers around the world have struggled to cope with plunging demand brought on by the global financial crisis, which helped send GM and rival Chrysler into bankruptcy earlier this year.

But a range of government measures to attract buyers has helped revive sales and many automakers have begun raising their forecasts.

Nissan, Japan's No.3 behind Toyota and Honda Motor Co, beat expectations with its second-quarter results and raised its full-year forecast, banking on reducing costs and better sales in China.

Nissan, 44 percent-owned by Renault SA, expects an operating profit of 120 billion yen ($1.3 billion) in the year to end-March, instead of the 100 billion yen loss it had forecast.

"It's a strong showing, demonstrating both Nissan's ability to manage through the economic crisis as well as the returns from its investments in emerging markets, particularly China," said Marc Desmidt, COO Asian equities, at BlackRock.

"Having said that, an important factor to watch out for is the sustainability of consumer demand as government stimulus around the world begins to come to an end."

COST CUTS KEY

Still, Japanese automakers are relying on cost cutting rather than any lasting surge in sales.

Toyota had an estimated annual budget of around $300 million for its Formula One team, which has never won a race since entering the series in 2002. It finished fifth out of 10 teams in this year's F1 constructors' rankings.

Honda, which quit the F1 series last December, said on Wednesday it was aiming to break even in Japan using just 70 percent of its capacity to build cars.

Honda last week nearly tripled its annual operating profit forecast for the year to March to 190 billion yen ($2.1 billion), far above consensus projections and despite lowering its dollar rate assumption to 85 yen for the second half from 90 yen.

Honda's Japanese operations are expected to stay in the red, but Chief Financial Officer Yoichi Hojo said Honda was shaving costs on components with the aim of erasing the losses even at the current depressed level of production.

"We can't get there right away, but the final step is to become profitable at the current level of production in Japan," Hojo told Reuters in an interview, adding the company hoped to get there in 2-3 years.

Japan is Honda's second-largest market after the United States, which is emerging from its worst downturn in decades.

U.S. auto sales hit an annualized rate of 10.46 million units in October, figures from industry tracking firm Autodata showed on Tuesday.

That is a level not seen in a year, except for July and August when the U.S. government's "cash for clunkers" incentives program sparked a surge in sales.

"In a nutshell, we can tell with confidence that we've seen the worst already past and we are seeing relative improvements in the market place and consumer demand," said Jesse Toprak, analyst with Truecar.com.
