2013-2017 Maserati GranCabrio I MC 4.7 V8 (460 Hp) Automatic

The Maserati GranCabrio MC 4.7 V8 Automatic, produced between 2013 and 2017, represents a high-performance iteration of Maserati’s open-top luxury grand tourer. Positioned as the flagship variant within the GranCabrio range during its production run, the MC version was developed to bridge the gap between the standard GranCabrio and the track-focused GranTurismo MC Stradale. It’s built upon the GranCabrio I platform (internally designated as the A3 platform, shared with the GranTurismo coupe) and aimed to deliver a more engaging driving experience while retaining the GranCabrio’s inherent luxury and comfort. This model catered to buyers seeking a blend of open-air motoring, Italian style, and substantial performance.

Powertrain & Engine Architecture

At the heart of the GranCabrio MC lies Maserati’s 4.7-liter V8 engine, designated the M145B. This engine is a naturally aspirated, 90-degree V8 featuring a dry-sump lubrication system, contributing to a lower center of gravity and improved handling. The MC variant benefits from upgrades derived from Maserati’s racing experience, including optimized intake and exhaust manifolds, and a revised engine management system. Direct fuel injection is employed, enhancing both power and efficiency. The engine produces 460 horsepower at 7,000 rpm and 520 Nm (383.53 lb-ft) of torque at 4,750 rpm. The engine’s valvetrain utilizes four valves per cylinder, operated by chain-driven double overhead camshafts. The six-speed automatic transmission, sourced from ZF, is specifically tuned for the MC version to provide quicker shifts and a more responsive driving experience. It features a torque converter and allows for manual gear selection via steering wheel-mounted paddles.

Driving Characteristics

The GranCabrio MC 4.7 Automatic delivers a distinctly sporting driving experience compared to the standard GranCabrio. The automatic transmission, while providing convenience, is programmed for performance, holding gears longer and downshifting more aggressively. Acceleration from 0 to 60 mph is achieved in approximately 4.7 seconds, with a top speed of 179.58 mph. The weight distribution, close to 51/49 front to rear, contributes to balanced handling. While not as raw or focused as the GranTurismo MC Stradale, the GranCabrio MC offers a compelling blend of performance and open-air enjoyment. The gear ratios are optimized for acceleration, but the automatic transmission can sometimes feel less engaging than a manual gearbox, particularly during spirited driving. The exhaust note is characteristically Maserati – a deep, resonant rumble that intensifies under acceleration.

Equipment & Trim Levels

The GranCabrio MC came standard with a comprehensive list of features, reflecting its positioning as the premium variant. Interior appointments included leather upholstery, power-adjustable seats with memory function, a premium audio system, and dual-zone climate control. The MC trim also featured unique styling cues, such as carbon fiber interior trim, sport seats, and a specific steering wheel design. Optional extras included a wider range of leather colors, upgraded audio systems, and parking sensors. The exterior was distinguished by specific alloy wheel designs, a more aggressive front bumper, and a rear spoiler.

Chassis & Braking

The GranCabrio MC utilizes a double-wishbone suspension setup at all four corners, with adaptive dampers to adjust to varying road conditions. The suspension is tuned for a firmer ride than the standard GranCabrio, enhancing handling precision. Braking duties are handled by ventilated discs on all four wheels, equipped with ABS and electronic brakeforce distribution. The braking system provides ample stopping power, but the GranCabrio’s considerable weight necessitates a firm pedal effort. The steering is a power-assisted rack-and-pinion system, offering good feedback and responsiveness.

Market Reception & Comparison

The GranCabrio MC was generally well-received by automotive critics, who praised its performance, styling, and luxurious interior. However, its fuel economy was often cited as a drawback, typical for a large-displacement V8 engine. Compared to the standard GranCabrio, the MC offered a noticeable improvement in handling and acceleration. Against competitors such as the Porsche 911 Cabriolet and BMW M6 Convertible, the GranCabrio MC distinguished itself with its Italian flair and more relaxed grand touring character. Reliability was generally good, although maintenance costs for a Maserati are typically higher than those for German rivals.

Legacy

The Maserati GranCabrio MC 4.7 V8 Automatic remains a desirable vehicle in the used car market. The naturally aspirated V8 engine is highly regarded by enthusiasts, and the MC variant’s performance upgrades add to its appeal. While modern convertibles offer greater fuel efficiency and advanced technology, the GranCabrio MC provides a unique driving experience that blends Italian passion with luxurious comfort. The M145B engine, while complex, has proven to be relatively durable with proper maintenance. Values have remained relatively stable, reflecting the car’s enduring appeal and the growing interest in classic and modern Maseratis.
