Maserati Ghibli

Maserati has unveiled the first images of the 2013 Ghibli ahead of its official debut next week at the Shanghai Auto Show. While the Ghibli badge has previously been reserved for coupés – both Giugiaro's 1967 original and Gandini's Biturbo-based 1992 Ghibli II – this is a four-door sports sedan to sit below the larger Quattroporte revealed in January at the North American International Auto Show. It's the first time the carmaker has built a car for the E-segment since the 1994 Quattroporte IV and is set to challenge high end of the Mercedes E-Class and BMW 5-series in AMG and M5 guises respectively.
