2017-2020 Mercedes-Benz S-class (W222 facelift ) S 560 V8 (469 Hp) 4MATIC G-TRONIC

The Mercedes-Benz S 560 4MATIC, produced from 2017 to 2020 as part of the W222 facelift generation of the S-Class, represented a high-performance variant within the flagship sedan range. Positioned as a premium offering, it sat above the S 450 and S 550 models, offering increased power and a more sporting driving experience while retaining the luxurious appointments expected of an S-Class. The W222 S-Class, launched in 2013, was a significant leap forward in automotive technology, and the 2017 facelift further refined the design and incorporated updated features. The S 560 4MATIC specifically combined a potent V8 engine with Mercedes-Benz’s 4MATIC all-wheel-drive system and the G-TRONIC nine-speed automatic transmission.

Powertrain & Engine Architecture

The heart of the S 560 4MATIC is the M176 4.0-liter V8 engine, internally designated as M176.980. This engine is a significant departure from the naturally aspirated V8s previously used in the S-Class, employing twin turbochargers and direct fuel injection to deliver substantial power and torque. The engine boasts a displacement of 3982 cm³ (243 cubic inches) and a compression ratio of 10.5:1. The direct injection system precisely meters fuel into the combustion chambers, optimizing combustion efficiency and reducing emissions. The twin-turbocharger setup utilizes a ‘hot-side-inside’ configuration, positioning the turbochargers within the V of the engine, resulting in a more compact engine layout and reduced turbo lag. The engine produces 469 horsepower at 5250-5500 rpm and a robust 700 Nm (516.29 lb-ft) of torque between 2000-4000 rpm.

The G-TRONIC 9G-TRONIC nine-speed automatic transmission is a crucial component of the S 560’s powertrain. This transmission is known for its smooth shifting, wide gear ratio spread, and efficiency. It allows the engine to operate within its optimal power band more frequently, contributing to both performance and fuel economy. The transmission features a torque converter lockup clutch that engages in most gears, minimizing slippage and improving efficiency. Manual shifting is available via steering wheel-mounted paddle shifters, providing the driver with greater control over gear selection.

Fuel Injection and Valvetrain

The M176 engine utilizes a multi-hole direct fuel injection system, delivering fuel directly into each cylinder at extremely high pressure. This ensures precise fuel atomization and efficient combustion. The engine also features a sophisticated valvetrain with continuously variable valve timing and lift (CAMTRONIC) on both the intake and exhaust sides. CAMTRONIC allows the engine to adjust valve timing and lift based on driving conditions, optimizing performance, fuel economy, and emissions. This technology contributes to the engine’s broad torque curve and responsive throttle response.

Driving Characteristics

The S 560 4MATIC delivers a driving experience that blends effortless power with refined comfort. The 469 hp and 516 lb-ft of torque provide brisk acceleration, with 0-60 mph times consistently recorded around 4.4 seconds. The 9G-TRONIC transmission contributes to smooth and seamless gear changes, enhancing the overall driving experience. The 4MATIC all-wheel-drive system provides excellent traction in all weather conditions, inspiring confidence and stability. Compared to the S 550, the S 560 offers noticeably more power and a more urgent response. While not as overtly sporty as some competitors, the S 560 provides ample performance for spirited driving. The gear ratios in the 9G-TRONIC are optimized for both acceleration and fuel efficiency, with a tall ninth gear for relaxed highway cruising. The suspension, typically utilizing Mercedes’ AIRMATIC air suspension system, provides a comfortable and controlled ride, effectively isolating passengers from road imperfections.

Equipment & Trim Levels

The S 560 4MATIC came standard with a comprehensive array of luxury features. Standard interior appointments included premium leather upholstery, heated and ventilated front seats with massage functions, a panoramic sunroof, and a Burmester surround sound system. The dashboard featured a dual 12.3-inch display screen, combining the instrument cluster and infotainment system into a single integrated unit. Standard safety features included adaptive cruise control, lane keeping assist, automatic emergency braking, and a 360-degree camera system. Optional extras included rear-seat entertainment systems, upgraded leather packages, and various driver assistance features. The S 560 was typically offered with a range of exterior color options and wheel designs, allowing buyers to personalize their vehicle. The trim level was generally considered the highest tier below the ultra-luxury Maybach models.

Chassis & Braking

The S 560 4MATIC utilizes an independent multi-link suspension system at both the front and rear axles. This suspension design provides a comfortable ride and precise handling. The AIRMATIC air suspension system, often standard equipment, further enhances ride quality by automatically adjusting the suspension damping and ride height based on road conditions and driving style. The braking system consists of ventilated discs at all four corners, providing ample stopping power. The anti-lock braking system (ABS) and electronic stability control (ESC) are standard features, enhancing safety and stability. The steering system is a rack-and-pinion setup with electric power steering, providing precise and responsive steering feel. The 4MATIC all-wheel-drive system distributes power between the front and rear axles as needed, optimizing traction and stability.

Market Reception & Comparison

The S 560 4MATIC was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and advanced technology. Reviewers noted the smooth and refined driving experience, as well as the impressive level of comfort and convenience features. Fuel economy was considered reasonable for a vehicle of its size and performance, with combined fuel consumption figures ranging from 8.5 to 8.8 l/100 km (27.7-26.7 US mpg). Compared to the S 550, the S 560 offered a noticeable performance advantage, while maintaining a similar level of luxury and refinement. Compared to other high-performance luxury sedans, such as the BMW 750i and Audi A8, the S 560 was often praised for its comfortable ride and advanced technology. Reliability reports generally indicated good reliability, although the complex technology could potentially lead to higher maintenance costs.

Technical Specifications

Legacy

The M176 engine, as featured in the S 560 4MATIC, has proven to be a robust and reliable powerplant. While the complex turbocharging and direct injection systems require regular maintenance, the engine is generally considered durable and capable of high mileage. The 9G-TRONIC transmission has also proven to be reliable, with few widespread issues reported. On the used car market, the S 560 4MATIC commands a premium price compared to lower-trim S-Class models, reflecting its higher performance and more comprehensive feature set. The W222 S-Class, in general, is considered a technologically advanced and luxurious vehicle, and the S 560 4MATIC represents a particularly desirable variant for those seeking a blend of performance, comfort, and prestige.
