PRAGUE--Volkswagen AG's (VOW.XE) Czech unit Skoda Auto AS said Thursday that its global sales rose 12.5% on the year to a record high in six months through the end of June, driven by a rebound in demand for the car maker's new models.

The car maker said steady demand for its eight reworked or recently launched passenger models contributed to the 522,500 vehicles it sold in the first half. Never before have Skoda Auto sales exceeded half a million cars during the January-June period. Apart from Europe the company targets customers in India, China and Russia.

The booming sales helped the car maker to nearly double its operating income to 425 million euros ($569 million) in the six months to end-June from EUR243 million in the corresponding period of 2013. Skoda Auto, fully owned by Volkswagen, doesn't report net profits for its half-year periods

Skoda said it plans to boost its annual sales to at least 1.5 million cars by 2018, compared with 920,750 vehicle sales in 2013, the company said.

Skoda is the Czech Republic's biggest exporter by sales. Its performance in the first half is a boost to the Czech economy, which is seen expanding about 3% in 2014 after two years of contraction.
