According to the report, Porsche is currently investing US$1 billion (AU$959 million) each year on such new models, as part of its recently finalised acquisition by the Volkswagen Group.
Previous reports have suggested the sports car - nicknamed ‘Ferrari Fighter’ - will carry the 960 model designation, and use a version of the Volkswagen Group’s new MMB mid-engined architecture.
This Porsche-developed platform will also underpin the next-generation Lamborghini Gallardo and Audi R8 models, though the Porsche-badged version will reportedly have to wait until the end of next year for a production go-ahead.
Also awaiting a production green-light is a sub-Panamera BMW 5 Series rival, with Porsche CEO Matthias Mueller reportedly describing the model as a mere “possibility”, and would not suggest a timeframe for the model.
Mueller is also said to have reaffirmed the indefinite postponement of the 550 sub-Boxster model, but confirmed the expansion of the Panamera lineup beyond the existing four-door bodystyle.
A shooting brake version is likely, as hinted at by the Sport Turismo Concept revealed in Paris, while a two-door coupe version is also possible following the Panamera’s 2013 mid-cycle facelift.
