Relationship with Porsche and the Volkswagen Law Volkswagen has always had a close relationship with Porsche, the Zuffenhausen-based sports car manufacturer founded in 1931 by Ferdinand Porsche, the original Volkswagen designer and Volkswagen company co-founder, hired by Adolf Hitler for the project. The first Porsche car, the Porsche 64 of 1938, used many components from the Volkswagen Beetle. The 1948 Porsche 356 continued using many Volkswagen components, including a tuned engine, gearbox and suspension. The two companies continued their collaboration in 1969 to make the VW-Porsche 914 and Porsche 914-6. (The 914-6 had a 6-cylinder Porsche engine, and the standard 914 had a Volkswagen engine.) Volkswagen and Porsche would collaborate again in 1976 on the Porsche 912-E (the USA only) and the Porsche 924, which used many Audi components and was built at Audi's Neckarsulm facilities. The 924 was originally designated for AUDI. Most Porsche 944 models were built there, although they used far fewer VW components. The Porsche Cayenne, introduced in 2002, shares its entire chassis with the Volkswagen Touareg and Audi Q7, and is built at the same Volkswagen factory in Bratislava that the other SUVs are built. In September 2005, Porsche announced it would increase its 5% stake in Volkswagen to 20% at a cost of €3 billion, with the intention that the combined stakes of Porsche and the government of Lower Saxony would ensure that any hostile takeover by foreign investors would be impossible. Speculated suitors included DaimlerChrysler, BMW, and Renault. In July 2006, Porsche increased their ownership again to 25.1%. On 4 March 2005, the European Commission brought an action against the Federal Republic of Germany before the European Court of Justice, claiming that the Volkswagen Law, which prevents any shareholder in Volkswagen from executing more than 20% of the total voting rights in the firm, was illegally restricting the flow of capital in Europe. On 13 February 2007, Advocate General Dámaso Ruiz-Jarabo Colomer submitted an opinion to the court in support of the action. This again opened the possibility of a hostile takeover of VW and so on 26 March of the same year Porsche took its holding of Volkswagen shares to 30.9%. Porsche formally announced in a press statement that it did not intend to take over Volkswagen, but intended the move to avoid a competitor's taking a large stake and to stop hedge
