Powertrain & Engine Architecture
At the heart of the Quattroporte S Q4 lies Maserati’s 3.0-liter V6 engine, designated the M156B. This engine is a direct descendant of the Ferrari-derived V6 used in previous Maserati models, but significantly reworked for greater efficiency and drivability. It features a 60-degree V-angle and employs direct gasoline injection (GDI) coupled with twin-turbochargers. The twin-scroll turbochargers are strategically positioned to minimize turbo lag and deliver a broad torque curve. The engine produces 410 horsepower at 5,500 rpm and a robust 550 Nm (405.66 lb-ft) of torque between 1,750 and 5,000 rpm. This power is channeled through an eight-speed automatic transmission, sourced from ZF, known for its smooth and responsive shifts. The “Q4” designation indicates Maserati’s intelligent all-wheel-drive system, which normally operates in a rear-wheel-drive configuration but can seamlessly engage the front wheels when traction is needed.
Driving Characteristics
The 410 hp and all-wheel-drive combination delivers a compelling driving experience. Acceleration from 0 to 60 mph takes approximately 4.7 seconds, and the car boasts a top speed of 177.71 mph. While not as overtly sporty as some of its competitors, the Quattroporte S Q4 offers a refined and confident ride. The eight-speed automatic transmission is well-tuned, providing quick and smooth gear changes. The all-wheel-drive system enhances stability and grip, particularly in inclement weather. Compared to the base model Quattroporte, the S Q4 offers a noticeable increase in performance. It also differs from the more powerful GTS variant, which utilizes a higher-output version of the 3.0-liter V6. The S Q4 strikes a balance between performance and fuel economy, making it a more practical choice for everyday driving.
Equipment & Trim Levels
The Quattroporte S Q4 came standard with a generous array of features, befitting its luxury positioning. These included leather upholstery, power-adjustable front seats with memory function, a premium sound system, dual-zone automatic climate control, and a touchscreen infotainment system. Standard safety features included a suite of airbags, anti-lock brakes, stability control, and traction control. Optional extras included features like adaptive cruise control, blind-spot monitoring, a panoramic sunroof, and upgraded leather options. Interior trim could be customized with a variety of wood veneers and carbon fiber accents. The exterior styling featured subtle “S Q4” badging to distinguish it from other Quattroporte models.
Chassis & Braking
The Quattroporte VI utilizes a double-wishbone front suspension and an independent multi-link rear suspension, providing a comfortable and controlled ride. The S Q4 model benefits from slightly stiffer spring rates and dampers compared to the base model, enhancing handling precision. Ventilated disc brakes are fitted to all four wheels, providing ample stopping power. The braking system is augmented by ABS (Anti-lock Braking System) and electronic brake-force distribution. The steering is a rack-and-pinion system with electric power assistance, offering a responsive and precise feel.
Market Reception & Comparison
The Maserati Quattroporte S Q4 was generally well-received by automotive critics. It was praised for its blend of luxury, performance, and all-weather capability. Reviewers noted the comfortable ride, refined interior, and responsive engine. Fuel economy, while not exceptional, was considered reasonable for a vehicle of its size and performance. Compared to rivals like the Porsche Panamera and BMW 7 Series, the Quattroporte S Q4 offered a more distinctive Italian flair and a more engaging driving experience. However, some critics pointed to the car’s complex infotainment system and occasional quality control issues.
Legacy
The Maserati Quattroporte S Q4 3.0 GDI V6 (410 hp) AWD Automatic represents a pivotal moment in Maserati’s history, showcasing the brand’s ability to blend Italian design with modern technology. While not without its quirks, the M156 platform proved to be a solid foundation for the Quattroporte. On the used car market, these models are generally considered reliable, although regular maintenance is crucial. The twin-turbo V6 engine, while powerful, requires diligent servicing to ensure longevity. The all-wheel-drive system adds to the car’s appeal in regions with harsh winters. Today, the Quattroporte S Q4 remains a desirable option for those seeking a luxurious and capable Italian sedan.
