Car and Driver's review of the Maserati GranCabrio highlights its exotic Italian styling and the thunderous soundtrack from its naturally aspirated V-8 engine. The GranCabrio is praised for being one of the few true four-seat convertibles that can carry adults in the rear without complaint, making it a practical grand tourer in addition to a style statement. The review notes that while the interior materials are high quality, the infotainment system lags behind competitors, and the ride can be firm on rough surfaces. The handling is described as secure and engaging, though not as sharp as rivals like the Porsche 911 Cabriolet. The author summarizes the GranCabrio as a charismatic, emotionally resonant convertible that prioritizes drama and style over razor-sharp dynamics. It recommended the Trofeo trim with the 580-hp twin-turbo V-8 for the best experience, noting that while not the fastest in its class, it delivers a unique combination of Italian flair, exclusivity, and open-air pleasure. Fuel economy is poor, but that's expected from a large luxury convertible.

MotorTrend's evaluation of the Maserati GranCabrio emphasizes its role as a lifestyle vehicle rather than a pure performance machine. The review notes that the GranCabrio is significantly heavier than its coupe counterpart due to structural reinforcements, which dulls acceleration and agility. The V-8 engine note is described as intoxicating, one of the best in the business, but the eight-speed automatic's shift logic can be lazy in normal driving. Handling is acceptable but the car understeers when pushed, and the brakes fade under repeated hard use, which is disappointing for a vehicle wearing the Trident badge. The article praises the convertible's wind management, with the air deflector effectively keeping the cabin serene at highway speeds. Cargo space with the roof down is limited, but the rear seat is genuinely useful. MotorTrend suggests that buyers considering a GranCabrio should also test the BMW 8 Series Convertible and Lexus LC 500 Convertible, which offer comparable style with better overall refinement. The final verdict portrays the GranCabrio as a beautiful and characterful car that prioritizes theater over track capability.
