Porsche spokesman Albrecht Bamler said the offer by VW “is not a viable option.”
Debt-laden Porsche, has been holding talks with a Qatar state investment fund on a possible investment.
Porsche confirmed earlier this month that it is in exclusive talks with the Qatar Investment Authority — the primary investment vehicle of the small, energy-rich state.
Bamler said that, for VW to take a stake in Porsche, the Wolfsburg-based automaker would have to take out credit worth 10.75 billion euro ($15.15 billion).
Porsche holds a roughly 51 per cent stake in Volkswagen, but ran up hefty debts in accumulating that holding and is now seeking a merger with the larger company. Exactly how that is to happen remains unclear.
