INTRODUCTION
The Maserati Quattroporte VI, launched in 2013 and facelifted in 2016, marked a departure for the brand, incorporating a new platform (M156) and a greater emphasis on luxury and technology. The S Q4 3.0 GDI variant, introduced with the facelift, combined a potent twin-turbocharged V6 engine with Maserati’s Q4 intelligent all-wheel-drive system and a smooth-shifting eight-speed automatic transmission. This configuration was aimed at buyers who desired a blend of performance, all-weather capability, and Italian elegance. Production of this specific variant spanned from 2017 to 2018, representing a relatively short but significant period in the Quattroporte’s evolution.
Powertrain & Engine Architecture
At the heart of the S Q4 lies Maserati’s 3.0-liter V6 engine, designated the M156B. This engine is a 60-degree V6 constructed primarily from aluminum. It utilizes direct fuel injection and is equipped with two twin-scroll turbochargers, delivering 430 horsepower at 5750 rpm and 580 Nm (427.79 lb-ft) of torque between 2250 and 4000 rpm. The engine benefits from an intercooler to manage intake air temperatures. The eight-speed automatic transmission, sourced from ZF, is a crucial component of the powertrain. It features a torque converter and offers both fully automatic and manual shifting modes. The Q4 all-wheel-drive system is a sophisticated setup that normally operates in rear-wheel drive, seamlessly engaging the front wheels when traction is lost. This system enhances stability and provides improved grip in adverse conditions.
Driving Characteristics
The S Q4 3.0 GDI delivers a compelling driving experience. The twin-turbo V6 provides strong acceleration, with a 0-60 mph time of around 4.6 seconds. The eight-speed automatic transmission shifts smoothly and responsively, contributing to a refined driving experience. While not as overtly sporty as some of its German rivals, the Quattroporte S Q4 offers a comfortable and engaging ride. The all-wheel-drive system provides confidence-inspiring handling, particularly in wet or snowy conditions. Compared to the base Quattroporte, the S Q4 offers significantly more power and a more dynamic driving experience. It also differs from the diesel variants, which prioritize fuel economy over outright performance. The gear ratios are tuned for a balance between acceleration and cruising efficiency.
Equipment & Trim Levels
The S Q4 trim level came standard with a generous array of features, including leather upholstery, power-adjustable front seats with memory function, a premium sound system, and a touchscreen infotainment system. Standard exterior features included 19-inch alloy wheels, bi-xenon headlights, and a rear spoiler. Optional extras included a panoramic sunroof, upgraded leather options, and advanced driver-assistance systems such as adaptive cruise control and blind-spot monitoring. The interior design emphasized Italian craftsmanship and luxury, with high-quality materials and attention to detail. The dashboard layout was relatively straightforward, with a focus on usability.
Chassis & Braking
The Quattroporte VI utilizes a double-wishbone front suspension and an independent multi-link rear suspension. This setup provides a comfortable ride while maintaining good handling characteristics. The S Q4 variant typically featured slightly stiffer springs and dampers compared to the base model, enhancing its dynamic capabilities. 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 features. The steering is electrically assisted, offering a precise and responsive feel.
Market Reception & Comparison
The Maserati Quattroporte VI S Q4 3.0 GDI was generally well-received by automotive critics. It was praised for its stylish design, luxurious interior, and strong performance. However, some reviewers noted that it lacked the ultimate level of refinement and technological sophistication offered by some of its German competitors. Fuel economy was also a point of criticism, with the combined fuel consumption of 9.7 l/100 km (24.2 US mpg) being relatively high for a vehicle in this class. Compared to the base Quattroporte, the S Q4 offered a significant performance upgrade, justifying its higher price tag. It also provided a compelling alternative to the diesel variants for buyers who prioritized performance over fuel economy.
Legacy
The Maserati Quattroporte VI S Q4 3.0 GDI represents a pivotal moment in Maserati’s history, showcasing the brand’s ability to blend Italian design with modern technology. The M156B engine and ZF eight-speed automatic transmission proved to be a reliable combination, and the Q4 all-wheel-drive system added a new dimension to the Quattroporte’s capabilities. On the used car market, these models hold their value reasonably well, appealing to buyers who appreciate their unique combination of luxury, performance, and Italian heritage. While maintenance costs can be higher than those of some German rivals, the Quattroporte S Q4 remains a desirable and rewarding vehicle for enthusiasts.
