"The operating result for the Volkswagen group before special items is significantly higher than market expectations for the first half of 2016," VW said in a statement, sending its shares zooming ahead by more than seven per cent on the Frankfurt stock exchange.
For the first six months, group operating profit before special items stood at 7.5 billion euros, the statement said.
That meant that operating result after special items amounted to 5.3 billion euros for the period from January to June, the carmaker said.
According to the group's half-year report for 2015, the corresponding year-earlier figure stood at 6.82 billion euros.
