Maserati has taken the GranCabrio convertible up a step with the new GranCabrio Sport. With more power, a faster gearshift and more aggressive look, the GranCabrio Sport has given Maserati a harder-edged convertible to sit alongside the GranTurismo S and the Quattroporte Sport GT S as the performance flagships of their respective ranges. The GranCabrio Sport, which is marketed in the U.S. with the name GranTurismo Convertible Sport, combines an upgraded 4.7-litre V8 engine with a 10 horsepower increase to 450 hp and improved fuel economy with the faster MC Auto Shift transmission. With a 285km/h top speed and a 0-100km/h sprint of 5.2 seconds, the GranCabrio Sport offers performance and luxury refinements both inside the cabin and underneath its body panels. Its six-speed transmission includes the MC Auto Shift mode and has been developed for the GranCabrio Sport directly from the transmission in the Quattroporte Sport GT S.
