Many of the small manufacturer’s sports cars are not built by Porsche at all, but by manufacturing firms such as Valmet, which is also contracted to build the Fisker Karma. The next-gen Porsche Boxster and Cayman are to be no different. Currently, Magna has the contract, but Porsche is thought to be considering a switch to Karmann for the next-generation models.
The move would entail switching from Austria, where the current Magna facility lies, to Germany. The underlying impetus for the switch is believed to be a desire to more closely protect the trade secrets in Porsche’s engineering of the next-generation Boxster and Cayman, due around 2011 or 2012. Secrecy fears are driven primarily by Magna’s own moves to secure the purchase of Opel from General Motors, making itself a player not just in manufacturing, but in design and engineering as well. That move has had many carmakers rethinking their partnerships with Magna.
