In 2005, Porsche SE, then an independent automaker run by Wolfgang Porsche, Ferdinand's grandson, bought 50.8% of Volkswagen AG in aborted takeover attempt. Ferdinand's other grandson Ferdinand Piech, then Volkswagen CEO, turned the tables on his cousin, acquiring Porsche SE, which became Volkswagen's largest shareholder, controlling a majority of its voting rights, but no longer owning Porsche AG.
