BRATISLAVA, Oct 9 (Reuters) - Slovak industrial output rose accelerated sharply in August, driven by a surge in car production with analysts expecting the positive trend to continue as further car capacity goes on-line. Industrial output rose by a real 13.7 percent year-on-year in August, up from 8.3 percent growth in July, the Slovak Statistics Office said on Monday. August output outperformed analysts' predictions for a 9.5 percent rise, with economists saying a low base effect from the last year also provided a positive contribution. "The production launch of the PSA Peugeot Citroen plant and the further influence of the Volkswagen plant help explain this (the growth)," said CSOB bank analyst Silvia Cechovicova. Cechovicova expected the strong rise in the car production to continue in the coming months, with South Korea's Kia Motors <000270.KS> Slovak unit to begin rolling out cars by the end of the year. Slovakia is expected to become the world's largest car manufacturer per capita once plants of French PSA Peugeot Citroen <PEUP.PA> and South Korean Kia Motors reach full output and join Volkswagen's <VOWG.DE> Slovak plant, which had a brief shutdown during the summer. "The resumption of production at the local Volkswagen branch and the launch of production as PSA was expected to significantly boost production and exports in Slovak economy in the second half of the year," said Slovenska Sporitelna analyst Maria Valachyova. Swings in car production can significantly influence the country's overall economic performance. Slovak PSA unit's production capacity reached 6700 cars in August, with 60,000 units expected to be manufactured by the end of the year, Slovakia's PSA spokesman Peter Svec said. Slovakia's Volkswagen spokeswoman Silvia Nosalova told Reuters the plant was running full shifts, adding the only slow-down seen ahead was the regular Christmas holiday. "This will have a positive effect on the foreign trade balance," Cechovicova added. The Statistics Office will release August foreign trade data date on Thursday, with analysts predicting a gap of 2.4 billion crown, compared to 7.3 billion crown gap reported in July.
