Powertrain & Engine Architecture
At the heart of the GranTurismo Sport 4.7 V8 Automatic lies Maserati’s naturally aspirated 4.7-liter V8 engine, designated the M145B. This engine is a direct descendant of the powerplant developed with Ferrari, showcasing a 90-degree V-angle for optimal balance. It features a dry-sump lubrication system, contributing to a lower center of gravity and improved handling. The engine utilizes direct fuel injection, enhancing efficiency and responsiveness. The valvetrain employs four valves per cylinder, maximizing airflow and contributing to the engine’s high-revving nature. The 460 horsepower and 383 lb-ft of torque are delivered with a characteristic Italian V8 soundtrack. Paired with this engine is a six-speed automatic transmission, specifically tuned for smooth shifts and responsive performance. While not a dual-clutch transmission, it was optimized for the engine’s power delivery and the GranTurismo’s grand touring character.
Driving Characteristics
The 4.7 V8 Automatic GranTurismo delivers a compelling blend of performance and comfort. Acceleration from 0-60 mph takes approximately 4.6 seconds, and it boasts a top speed of 185.79 mph. The automatic transmission, while not as lightning-fast as modern dual-clutch units, provides smooth and predictable gear changes. Compared to the manual transmission versions, the automatic offers a more relaxed driving experience, particularly in city traffic. However, it sacrifices some of the driver engagement and control offered by the manual. Compared to the base 4.2-liter V8, the 4.7-liter engine provides a noticeable increase in power and torque throughout the rev range. The Sport trim also included a slightly more aggressive suspension setup, enhancing handling and cornering ability.
Equipment & Trim Levels
The Sport trim of the GranTurismo I (facelift 2017) came standard with a range of premium features. Interior appointments included leather upholstery, power-adjustable seats, and a leather-wrapped steering wheel. Standard technology included a Maserati Touch Control infotainment system, navigation, and a premium audio system. The Sport trim also featured unique exterior styling cues, such as a more aggressive front bumper, side skirts, and a rear spoiler. Optional extras included carbon fiber interior trim, upgraded leather options, and a variety of driver-assistance systems.
Chassis & Braking
The GranTurismo’s chassis is based on a steel spaceframe, providing a rigid and lightweight platform. The suspension utilizes double wishbones at all four corners, offering a comfortable ride and precise handling. The Sport trim featured stiffer springs and dampers, reducing body roll and improving responsiveness. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. An anti-lock braking system (ABS) is standard, enhancing safety and control. The GranTurismo’s weight distribution is nearly 50/50, contributing to its balanced handling characteristics.
Market Reception & Comparison
The Maserati GranTurismo I (facelift 2017) Sport 4.7 V8 Automatic was generally well-received by automotive critics. It was praised for its stunning design, luxurious interior, and powerful engine. However, some critics noted its relatively high fuel consumption and the aging technology of the automatic transmission. Compared to rivals such as the Porsche 911 and Aston Martin DB11, the GranTurismo offered a unique blend of Italian style and grand touring comfort. Its fuel economy was notably lower than many competitors, and its reliability record was somewhat mixed.
Legacy
The Maserati GranTurismo I (facelift 2017) Sport 4.7 V8 Automatic represents a high point in Maserati’s modern history. The M145B V8 engine is considered a masterpiece of naturally aspirated engine design, and the GranTurismo’s timeless styling continues to turn heads. While the automatic transmission may not be the most technologically advanced, it provides a smooth and refined driving experience. On the used car market, these models hold their value well, appealing to collectors and enthusiasts seeking a unique and stylish Italian sports car. Maintenance costs can be higher than some competitors due to the Maserati’s exotic nature and the complexity of the V8 engine, but the driving experience and ownership prestige often outweigh these concerns.
