Porsche will launch a fourth model line to complement its current Boxster and 911 models and the imminent Cayenne SUV, the Financial Times Deutschland said.
The newspaper cited suppliers who said Porsche was already preparing to expand its new Leipzig plant, where the latest model would be built.
The FTD said that Porsche would probably announce its new car line mid-year.
The paper quoted a major supplier as saying that his firm had been warned to inspect a major increase in component orders which would not all be for the new Cayenne.
The FTD said that Porsche was developing the new car with engineering service provider Bertrandt because its own R&D centre is fully booked with work for other manufacturers.
The new Porsche will be the latest model to be built in one of the newly-established car factories in Leipzig, an industrial city located in the former East Germany. Volkswagen‘s Phaeton is already produced there and production of a new BMW model is planned.
