Volkswagen's successful bid to take over luxury German carmaker Porsche marks the end of a bitter family power struggle and the start of a new era. Last week, Volkswagen agreed to buy a 42% stake in the sports car unit of Porsche Automobil Holding SE for about EUR 3.3 billion by year-end. "VW and Porsche are entering a new era -- the company has the means to become number one," chief executive Martin Winterkorn said Friday. He also said “Porsche is a real enrichment for our company’s portfolio,” Volkswagen is Europe's biggest automaker and this takeover marks an end of a bitter battle which began as early as 2005. The combined company will have 10 brands including Porsche. At present, the brands include Audi, Bentley, Skoda, Seat, Bugatti and Lamborghini. The deal is set to make the Gulf state of Qatar the third-largest investor in the combined company. The deal also includes VW taking over Porsche Holding Salzburg, Europe’s biggest car dealer.
