The report, with US industry paper Automotive News, comes on the heels of Maserati confirming the new model's production future - although a 2014 debut was previously expected.
Technical details remain unclear, but reports have suggested the Ghibli will utilise a massively modified version of the platform that underpins the new Chrysler 300, while benefiting from Maserati performance tuning.
The Ghibli draws its name from two Maserati models of decades gone by: a two-seater coupe and convertible pair from the 60s and early 70s, and a four-seater coupe offered in the early 90s.
The marque currently turns over around 7000 cars per year with its GranTurismo and Quattroporte, but wants to ramp up to 50,000 units annually over the next few years.
