INTRODUCTION
The Maserati Quattroporte VI S 3.0 GDI Automatic, produced from 2017 to 2018, represents a compelling blend of Italian luxury and performance. Built on the M156 platform – a significant update to the fifth-generation Quattroporte’s architecture – this variant aimed to broaden the model’s appeal. The “S” designation indicated a mid-range trim level, positioned above the base model but below the more potent GTS. Its 3.0-liter twin-turbocharged V6 engine, coupled with an eight-speed automatic transmission, delivered a refined yet engaging driving experience, making it a popular choice for buyers seeking a sophisticated grand tourer.
Powertrain & Engine Architecture
At the heart of the Quattroporte S 3.0 GDI lies Maserati’s M156B engine, a 2.979-liter (181.79 cubic inches) V6. This engine is notable for its use of direct fuel injection and twin-turbocharging, technologies that contribute to its impressive power output of 430 horsepower at 5750 rpm and 580 Nm (427.79 lb-ft) of torque available from 2250 to 4000 rpm. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The twin-turbochargers, coupled with an intercooler, minimize turbo lag and provide a broad, usable powerband. The engine is longitudinally mounted in the front of the vehicle. The eight-speed automatic transmission, sourced from ZF, is a crucial component of the powertrain. It features a torque converter and provides smooth, quick shifts, contributing to both performance and fuel efficiency. The transmission is programmed with multiple driving modes, allowing the driver to tailor the shift points to their preferences.
Driving Characteristics
The Quattroporte S 3.0 GDI Automatic delivers a driving experience that prioritizes comfort and refinement without sacrificing performance. The 430 hp engine provides ample power for effortless cruising and confident overtaking. Acceleration from 0 to 60 mph takes approximately 4.8 seconds, and the car boasts a top speed of 178.95 mph. The eight-speed automatic transmission contributes to a smooth and seamless driving experience, with well-chosen gear ratios that keep the engine in its optimal powerband. Compared to the base model Quattroporte, the S variant offers noticeably more responsive acceleration. However, it doesn’t quite match the raw power and aggressive character of the GTS, which features a more powerful V8 engine. The suspension is tuned to provide a comfortable ride, absorbing bumps and imperfections in the road while maintaining good body control. The steering is precise and well-weighted, offering a good connection to the road.
Equipment & Trim Levels
The Quattroporte S 3.0 GDI Automatic came standard with a comprehensive array of luxury features. Interior appointments typically included leather upholstery, power-adjustable front seats with memory function, dual-zone automatic climate control, and a premium audio system. Standard technology features included an 8.4-inch touchscreen infotainment system, navigation, Bluetooth connectivity, and a rearview camera. Optional extras included upgraded leather options, a panoramic sunroof, adaptive cruise control, blind-spot monitoring, and a more powerful Harman Kardon audio system. The exterior styling of the S variant was generally similar to other Quattroporte models, but it often featured unique wheel designs and subtle trim accents.
Chassis & Braking
The Quattroporte S 3.0 GDI utilizes a double wishbone suspension setup at the front and an independent multi-link suspension at the rear. This configuration provides a good balance of ride comfort and handling precision. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. An anti-lock braking system (ABS) is standard, enhancing safety and control during emergency braking situations. The steering system employs an electric power steering rack and pinion, offering precise and responsive steering feel. The car rides on 19-inch alloy wheels, typically fitted with 245/45 R19 tires at the front and 275/40 R19 tires at the rear.
Market Reception & Comparison
The Maserati Quattroporte S 3.0 GDI Automatic was generally well-received by automotive critics. Reviewers praised its blend of luxury, performance, and Italian styling. The engine was lauded for its smooth power delivery and responsive acceleration. However, some critics noted that the car’s fuel economy was relatively poor compared to its competitors. Compared to the base model Quattroporte, the S variant offered a significant performance upgrade, making it a more appealing option for drivers who prioritized driving enjoyment. Compared to the GTS, the S variant offered a more balanced combination of performance and price. The Porsche Panamera and BMW 7 Series were often cited as key competitors.
Legacy
The Maserati Quattroporte VI S 3.0 GDI Automatic has established itself as a desirable used car. The M156B engine, while not without its complexities, has proven to be relatively reliable when properly maintained. Regular servicing, including oil changes and timing belt replacements, is crucial for ensuring long-term reliability. The eight-speed automatic transmission has also proven to be durable. Today, these cars represent a compelling value proposition for buyers seeking a luxurious and performance-oriented sedan with Italian flair. The combination of a powerful engine, comfortable ride, and elegant styling ensures its continued appeal in the used car market.
