BRATISLAVA, Dec 8 (Reuters) - Slovak industrial output accelerated in October thanks to a continuing production boost in auto manufacturing, and analysts said on Friday they expect the trend to continue in the coming months. Industrial output rose by a real 11.1 percent year-on-year in October, accelerating from a revised 9.8 percent increase in September, Statistics Office data released on Friday showed. The output growth was a touch below the market forecast of an 11.5 percent rise, but analysts said the data nonetheless confirmed the rising trend. "A further acceleration (of industrial output) is expected due to the expected production boosts at PSA Peugeot Citroen's and KIA's plants," said ING bank analyst Eduard Hagara. "It confirms what GDP growth data showed, that new production is starting and the economy's potential is rising," Hagara added. The Slovak economy grew by a record 9.8 percent in the third quarter and analysts said investments, shown in inventories, and domestic demand were the key drivers. Output in the strategic automotive industry, the backbone of Slovakia's economy, jumped by 41.1 percent on the year in October after a 26.2 rise in the previous month. "This confirms that this category will be the driver, not just until the year-end, but also in the coming year," said CSOB bank analyst Silvia Cechovicova. Slovakia is expected to become the world's largest car producer per capita once plants of French PSA Peugeot Citroen <PEUP.PA> and South Korean Kia Motors <000270.KS> reach full output and join Volkswagen's <VOWG.DE> Slovak plant. The three factories should together will have an annual output of over 800,000 units in 2008 or 2009.
