The Maserati GranCabrio MC 4.7, produced from 2018 to 2020, represents the final iteration of the first-generation GranCabrio (internally designated as the MQ platform). This facelifted model, distinguished by its aggressive styling cues borrowed from the Maserati MC Stradale, served as the performance-oriented pinnacle of the GranCabrio range. Positioned as the top-tier variant, it offered a more focused driving experience compared to the standard GranCabrio and GranCabrio Sport models. The “MC” designation signifies its connection to Maserati’s racing heritage, specifically the Maserati Corse (racing) division. It was primarily marketed towards enthusiasts seeking a luxurious open-top grand tourer with genuine sports car performance.

Powertrain & Engine Architecture
At the heart of the GranCabrio MC 4.7 lies Maserati’s 4.7-liter V8 engine, designated as the M145B. This naturally aspirated powerplant is a 90-degree V8 featuring four valves per cylinder and a direct fuel injection system. The engine benefits from dual overhead camshafts and variable valve timing, contributing to its broad powerband and responsive throttle characteristics. The 460 horsepower peak is achieved at 7,000 rpm, while the substantial 520 Nm (383.53 lb-ft) of torque is available at 4,750 rpm. The engine’s architecture is rooted in Ferrari’s V8 designs, reflecting the close technical relationship between the two brands at the time. The six-speed automatic transmission, sourced from ZF, is specifically tuned for the GranCabrio MC, offering quicker shifts and a more engaging driving experience compared to the standard GranCabrio’s transmission. It features a manual mode allowing the driver some control over gear selection.
Driving Characteristics
The GranCabrio MC 4.7 delivers a distinctly sporting driving experience. The combination of the high-output V8 and the responsive automatic transmission results in brisk acceleration – 0 to 60 mph in approximately 4.7 seconds and a top speed of 180.82 mph. While not as raw or focused as a dedicated sports car, the GranCabrio MC offers a compelling blend of performance and comfort. The automatic transmission, while improved over earlier versions, isn’t as lightning-fast as modern dual-clutch transmissions. However, it provides smooth and predictable shifts, making it well-suited for both spirited driving and relaxed cruising. The exhaust note is a defining characteristic, delivering a classic Italian V8 roar that intensifies under acceleration. The car feels planted and stable at high speeds, thanks to its relatively long wheelbase and well-tuned suspension.
Equipment & Trim Levels
The GranCabrio MC 4.7 came generously equipped as standard. Key features included leather upholstery, power-adjustable and heated front seats, a premium audio system, bi-xenon headlights, and a sophisticated infotainment system. The “MC” trim also included unique exterior styling elements, such as a more aggressive front bumper, side skirts, and a rear spoiler. Interior trim options included a variety of leather colors and wood veneers. Optional extras included a panoramic sunroof, adaptive cruise control, and a rear parking camera. The overall interior ambiance focused on luxury and craftsmanship, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The GranCabrio MC 4.7 utilizes a double-wishbone suspension setup at all four corners, providing a good balance between ride comfort and handling precision. The suspension is tuned to be slightly firmer than the standard GranCabrio, enhancing body control and reducing roll during cornering. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The car is equipped with an Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) as standard safety features. The steering is a power-assisted rack and pinion system, offering precise and responsive steering feel.
Market Reception & Comparison
The GranCabrio MC 4.7 was generally well-received by automotive critics. It was praised for its powerful engine, luxurious interior, and engaging driving experience. However, its relatively high fuel consumption and somewhat dated infotainment system were noted as drawbacks. Compared to the standard GranCabrio, the MC offered a more focused and dynamic driving experience. Against competitors like the Porsche 911 Cabriolet and BMW 6 Series Convertible, the GranCabrio MC distinguished itself with its Italian flair, luxurious interior, and distinctive V8 soundtrack. Fuel economy was significantly lower than its German rivals, and reliability was a mixed bag, with some owners reporting issues with the electrical system.
Legacy
The Maserati GranCabrio MC 4.7 represents the culmination of the first-generation GranCabrio’s development. While production ended in 2020, these models continue to be sought after by enthusiasts. The 4.7-liter V8 engine is known for its durability, although regular maintenance is crucial. The automatic transmission, while generally reliable, can require expensive repairs if neglected. On the used car market, the GranCabrio MC 4.7 commands a premium over the standard GranCabrio models, reflecting its enhanced performance and exclusivity. It remains a compelling choice for those seeking a stylish and engaging open-top grand tourer with a genuine Italian pedigree.
