No, VW does not own Porsche but they were both started by Dr. Ferdinand Porsche and continue to have very close relationship. In fact Dr. Ferdinand Porsche's grandson (Ferdinand Piech) was the president of VW until 2002.Originally Posted by sHpReLuDe
Also, in late 2005 the Porsche and Piech families started to aquire VW shares and now they own just over 25%. So in some way Porche owns part of VW. But it is not corporate shares just the private families controlling both companies.
