Volkswagen has taken the crown as the world's top carmaker after its sales overtook those of Japanese rival Toyota during the first half of the year. Toyota said it sold 5.02 million vehicles worldwide between January and June, falling below earlier figures from Volkswagen of 5.04 million units shifted in the same period. U.S.-based General Motors was sitting in third spot with 4.86 million in sales, according to AFP.Camry and Prius maker Toyota broke GM's decades-long reign as the world's top automaker in 2008 but lost the crown three years later as Japan's 2011 earthquake-tsunami disaster hammered production and disrupted the supply chains of the country's automakers.In 2012, Toyota again overtook its Detroit rival, which sells the Chevrolet and luxury Cadillac brands, to grab the top spot globally. But the Japanese automaker is expecting sales this year to slip to 10.15 million from a record 10.23 million vehicles in 2014, owing to a shaky outlook for Japan and as it beefs up its focus on quality after a string of safety scandals.Volkswagen is now in pole position as the German automaker rides momentum in emerging economies that will likely see it take the top spot in annual global auto sales for the first time in 2015.In April, Toyota announced it was ending a freeze on building new factories by unveiling plans for a $1 billion plant in rising industry power Mexico and another production line in China. The carmaker began operating a new Thai plant in 2013, but since then it had halted investment as the global car market struggled with oversupply and weak demand. Toyota, among other major automakers, has also been struggling to recover a reputation for safety after the recall of millions of cars around the world for various problems, including an exploding air bag crisis at supplier Takata. In the first half, Toyota's sales grew in U.S., Mexico and China, according to AP. But it has said it's expecting to sell fewer trucks and cars this year, forecasting sales will fall 1 percent year-on-year to 10.15 million vehicles. Volkswagen sold 10.14 million vehicles in 2014. VW makes the Beetle and Golf cars, and also has the Porsche, Bugatti and Audi brands under its group. GM, which makes the Cadillac and Opel cars, was third at 9.92 million vehicles in global sales last year. The ranking could still change when numbers come in for the entire year. None of the automakers say they are trying to be No. 1 for the sake of being No. 1. But the industry crown is coveted and significant.
