Dr.-Ing. h.c. F. Porsche AG, usually shortened to Porsche AG (German pronunciation: [ˈpɔɐ̯ʃə] (About this soundlisten); see below), is a German automobile manufacturer specializing in high-performance sports cars, SUVs and sedans. The headquarters of Porsche AG is in Stuttgart, and is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE. Porsche's current lineup includes the 718 Boxster/Cayman, 911, Panamera, Macan, Cayenne and Taycan.
Ferdinand Porsche founded the company called "Dr. Ing. h. c. F. Porsche GmbH" in 1931, with main offices at Kronenstraße 24 in the centre of Stuttgart. Initially, the company offered motor vehicle development work and consulting, but did not build any cars under its own name. One of the first assignments the new company received was from the German government to design a car for the people, that is a "Volkswagen". This resulted in the Volkswagen Beetle, one of the most successful car designs of all time. The Porsche 64 was developed in 1939 using many components from the Beetle.
The company has always had a close relationship with, initially, the Volkswagen (VW) marque, and later, the Volkswagen Group (which also owns Audi AG), because the first Volkswagen Beetle was designed by Ferdinand Porsche.
The two companies collaborated in 1969 to make the VW-Porsche 914 and 914-6, whereby the 914-6 had a Porsche engine, and the 914 had a Volkswagen engine. Further collaboration in 1976 resulted in the Porsche 912E (US only) and the Porsche 924, which used many Audi components, and was built at Audi's Neckarsulm factory, which had been NSU's. Porsche 944s were also built there, although they used far fewer Volkswagen components. The Cayenne, introduced in 2002, shares its chassis with the Volkswagen Touareg and the Audi Q7, which is built at the Volkswagen Group factory in Bratislava, Slovakia.
