Daimler's car division has said it will lengthen its Christmas holiday production stoppage this year and is considering cutting the work week from 35 hours to 30.

Renschler acknowledged that the company -- whose truck brands include Mercedes-Benz, Freightliner, Western Star and Fuso -- faces weak demand in the coming months.

'We're looking at a first half of next year that looks less attractive,' Renschler said, noting that the U.S. market in particular remains difficult. 'It will take a lot longer there before a recovery comes.'

In October, the company said it would discontinue its Sterling brand in the U.S. and close two truck production facilities there, cutting 3,500 jobs.

Renschler would not rule out further savings in the U.S.

'We plan in scenarios and are prepared for all eventualities,' he said, without elaborating.

Renschler said the problems in the U.S. truck market lie in part in the current consolidation of the logistics sector there. Many smaller fleets gave up their business this summer, especially after oil prices reached record highs in July -- meaning that there are a lot of trucks on the market at the moment.

Despite that, 'we're well positioned in the USA,' Renschler said. He noted that the company plans to open another production facility in Mexico next year.

Renschler declined to give an outlook for the worldwide truck market in 2009, but said Daimler still expects to see record revenues for the truck business in 2008. The company hopes for growth in developing markets such as China, India, Brazil and Russia.

Daimler is due to decide by the end of this year whether to enter a partnership with the Russian truckmaker Kamaz.

Renschler stressed that Daimler does not plan any cutbacks in the company's research and development activities.

Daimler's truck division, which employs some 80,000 worldwide, posted revenue of euro28.5 billion in 2007, with 467,667 trucks sold.
