According to market speculation this would be achieved by buying out the 20% stake owned by the state of Lower Saxony, though Lower Saxony and Porsche both deny any such plans.
A majority share in VW would allow Porsche to reduce both costs and development time so that they can meet the 130g/km C02 emissions standard by 2012. Currently Porsche’s most efficient model, the Cayman, outputs 222g/km of C02 and the Cayenne Turbo SUV a massive 358g/km. Porsche has ruled out a diesel model, but they are working in conjunction with Audi and Bosch to develop a petrol-electric powered V8 for the Cayenne. It is also rumored that a hybrid engine will be available on the upcoming Panamera from launch. Economies of sale would also be increased by sharing more components with the VW group of companies.
