2008-2012 Maserati GranTurismo I S 4.7 (440 Hp) Automatic

The Maserati GranTurismo S 4.7, produced between 2008 and 2012, represents a significant iteration of Maserati’s flagship coupe. Positioned as a performance-oriented variant within the first generation (GranTurismo I) of the modern GranTurismo line, the S 4.7 aimed to deliver a more engaging driving experience than the standard model while maintaining the luxurious character expected of a Maserati. It played a crucial role in re-establishing Maserati as a serious contender in the grand touring segment, competing with vehicles like the Porsche 911 and Aston Martin DB9. This specific configuration, featuring the 4.7-liter V8 engine paired with an automatic transmission, was a popular choice for buyers seeking a blend of performance and convenience.

Technical Specifications

Powertrain & Engine Architecture

The heart of the GranTurismo S 4.7 is the M139S 4.7-liter V8 engine. This engine, developed in collaboration with Ferrari, is a naturally aspirated powerplant featuring a 90-degree V8 configuration. It utilizes a dry-sump lubrication system, a design typically found in high-performance applications, which allows for a lower engine placement within the chassis, improving the car’s center of gravity. The engine employs a multi-point fuel injection system and four valves per cylinder, contributing to its high output. The 11.25:1 compression ratio further enhances performance. The engine’s sound is a defining characteristic, delivering a classic Italian V8 roar. The automatic transmission paired with the M139S is a six-speed unit sourced from ZF. This transmission offers both fully automatic operation and a manual mode, allowing drivers to exert more control over gear selection. The transmission is tuned for smooth shifts, prioritizing comfort during normal driving while providing responsive downshifts when in sport mode.

Driving Characteristics

The GranTurismo S 4.7 Automatic delivers a compelling grand touring experience. The 440 horsepower and 361 lb-ft of torque provide ample power for effortless cruising and spirited acceleration. While the automatic transmission doesn’t offer the same level of engagement as a manual gearbox, it provides smooth and quick shifts, making it well-suited for everyday driving. The 0-60 mph time of around 4.8 seconds is respectable for a grand tourer of this size and weight. The car feels planted and stable at high speeds, thanks to its long wheelbase and well-tuned suspension. Compared to the standard GranTurismo, the S 4.7 offers a noticeably more responsive throttle and a more aggressive exhaust note. It also benefits from a slightly stiffer suspension setup, which reduces body roll in corners. However, it doesn’t sacrifice ride comfort, remaining a comfortable vehicle for long journeys.

Equipment & Trim Levels

The GranTurismo S 4.7 Automatic came standard with a generous array of features, befitting its luxury positioning. Standard equipment included leather upholstery, power-adjustable front seats, a premium audio system, automatic climate control, and bi-xenon headlights. Optional extras were plentiful, allowing buyers to personalize their vehicles. These included features like carbon fiber interior trim, upgraded leather options, a rear seat entertainment system, and a variety of exterior styling enhancements. The S 4.7 trim generally featured sportier styling cues compared to the base model, including unique alloy wheel designs and subtle aerodynamic enhancements.

Chassis & Braking

The GranTurismo S 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 in the S 4.7 compared to the standard GranTurismo, enhancing its cornering ability. The braking system consists of ventilated disc brakes at all four wheels, providing ample stopping power. The S 4.7 typically featured larger brake rotors and calipers than the base model, further improving braking performance. Stability control and traction control systems are standard, enhancing safety and driver confidence.

Market Reception & Comparison

The Maserati GranTurismo S 4.7 was generally well-received by automotive critics. It was praised for its stunning design, luxurious interior, and powerful engine. The automatic transmission was sometimes criticized for not being as engaging as a manual gearbox, but it was acknowledged as being smooth and responsive. Compared to the standard GranTurismo, the S 4.7 offered a more exciting driving experience, making it the preferred choice for enthusiasts. Fuel economy, however, was a common criticism, with the combined fuel consumption of 15.23 l/100 km being relatively high. Compared to the GranTurismo 4.2, the S 4.7 offered a significant performance upgrade, while the 4.2 was often seen as a more comfortable and refined option.

Legacy

The Maserati GranTurismo S 4.7 has proven to be a relatively reliable vehicle, although maintenance costs can be high due to its Italian heritage and complex engineering. The M139S engine is generally considered to be robust, but regular maintenance is essential to ensure its longevity. The ZF six-speed automatic transmission is also known for its durability. In the used car market, the GranTurismo S 4.7 remains a desirable vehicle, particularly among those seeking a stylish and powerful grand tourer. Its classic Italian design and engaging driving experience continue to appeal to enthusiasts. While newer grand tourers offer more advanced technology and improved fuel economy, the GranTurismo S 4.7 retains a special charm and character that sets it apart.
