By SARAH DiLORENZOGENEVA (AP) â¿¿ The European car market is going to be tough for five more years, Renault CEO Carlos Ghosn predicted Tuesday, and the only way for struggling carmakers to survive is to push into other markets. Europe's carmakers are finding it harder to recover from the collapse of the car market in 2008 than some of their rivals in the U.S. and Asia. Europeans are buying fewer new cars as their economies grow weakly, or not at all. On top of this, automakers are struggling with idle production lines and overcapacity. Building a car in Europe is more expensive than in many other parts of the world thanks to rigid labor agreements that drive up wages and benefits. Those same agreements also make it difficult to transfer jobs elsewhere. Ghosn said he is already trying to make Renault's factories in France more competitive by seeking a deal with its unions on staffing and labor practices â¿¿ but that's a long-term solution. Carmakers have been hit hard by the European financial crisis, which has sent unemployment soaring and led to a sustained fall in overall retail sales across the region; car sales in the EU pulled back another 7.8 percent in 2012, the fifth year of decline. Renault is looking to make up for the shortfall in Europe by tapping markets outside the region and the company's alliance with Nissan helps it do just that. The carmaker saw its net profit fall 15 percent last year, but it's still faring better than rival PSA Peugeot Citroen, which is heavily focused on the French market. PSA posted a â¿¬5 billion ($6.5 billion) loss last year. On the sidelines of the Geneva Motor Show Tuesday, Ghosn said he was buckling down for a few more tough years of declining sales.
