The GranTurismo Convertible is powered by the company’s top-level 4.7-liter V8, making 433-hp. This seems to indicate that unlike Maserati’s other models, the 405-hp 4.2-liter V8 will not be offered. What this also may indicate is that a possible GranCabrio S model could make even more power. After all, with the added weight of the necessary chassis stiffening required in a drop-top, the 433-hp will deliver performance on par with the base-engine coupe.
