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

The Mercedes-Benz S 560 V8 (469 hp) G-TRONIC represents a high-performance iteration of the W222 S-Class facelift, produced from 2017 to 2020. Positioned as a premium offering within the S-Class range, it sat above the S 450 and S 550 models, offering increased power and a more sporting driving experience while retaining the flagship luxury and technology for which the S-Class is renowned. This variant was part of the fourth generation of the S-Class (internally designated W222), which debuted in 2013 and received a significant facelift in 2017, incorporating updated styling, enhanced technology, and revised powertrains. The S 560 V8 aimed to appeal to buyers seeking both opulent comfort and substantial performance in a full-size luxury sedan.

Powertrain & Engine Architecture

The heart of the S 560 V8 is the M176 4.0-liter V8 engine. 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 both high power and improved efficiency. The engine code, M176.980, signifies a specific calibration for the S 560, tuned to produce 469 horsepower at 5250-5500 rpm and 700 Nm (516.29 lb-ft) of torque between 2000-4000 rpm. The compression ratio is 10.5:1. The engine utilizes a sophisticated direct injection system, injecting fuel directly into the combustion chamber for precise control and optimized combustion. The twin-turbocharger setup features a ‘hot-side-inside’ configuration, placing the turbochargers within the V of the engine, reducing exhaust manifold length and improving responsiveness.

Paired with the V8 engine is the 9G-TRONIC nine-speed automatic transmission. This transmission is a key component of the S 560’s performance and efficiency. The 9G-TRONIC features a wide gear ratio spread, allowing for both strong acceleration and relaxed highway cruising. It utilizes a torque converter for smooth launches and a sophisticated electronic control system to optimize shift points based on driving conditions. The transmission is designed for rear-wheel drive, although 4MATIC all-wheel drive was available as an option. The transmission’s gear ratios are carefully calibrated to maximize the engine’s torque output and deliver a refined driving experience.

Fuel Injection and Valvetrain

The M176 engine employs a multi-hole direct injection system, utilizing piezo injectors for precise fuel metering. This system allows for stratified charge operation under certain conditions, further enhancing efficiency. The engine also features variable valve timing (VVT) on both the intake and exhaust sides, optimizing valve timing for improved performance and fuel economy across the engine’s operating range. The valvetrain utilizes roller finger followers to reduce friction and improve durability.

Driving Characteristics

The S 560 V8 delivers a markedly different driving experience compared to the lower-powered S 450 or even the S 550. The increased horsepower and torque result in significantly quicker acceleration. Mercedes-Benz quoted a 0-60 mph time of 4.5 seconds, and a 0-100 km/h time of 4.7 seconds. In real-world driving, the S 560 feels effortlessly powerful, providing strong acceleration in all situations. The 9G-TRONIC transmission contributes to a smooth and refined driving experience, with seamless gear changes. Compared to a hypothetical manual transmission version (which was not offered), the automatic provides greater convenience and ease of use, particularly in city traffic. While not overtly sporty, the S 560 offers a more engaging driving experience than its more comfort-oriented siblings, with a noticeable increase in responsiveness and a more authoritative feel.

Equipment & Trim Levels

The S 560 V8 came standard with a comprehensive array of luxury features. Interior upholstery typically consisted of high-quality leather, with a wide range of color options available. Standard features included heated and ventilated front seats with massage functions, a premium Burmester surround sound system, a large infotainment display with Mercedes-Benz’s COMAND system, and a suite of advanced driver-assistance systems, including adaptive cruise control, lane-keeping assist, and automatic emergency braking. The dashboard configuration was characterized by a dual-screen display, showcasing the infotainment system and digital instrument cluster. Optional extras included rear-seat entertainment systems, a panoramic sunroof, and various interior trim packages, allowing buyers to personalize their vehicle to their preferences. The S 560 was often specified with the AMG Line package, which added more aggressive styling cues and sportier interior appointments.

Chassis & Braking

The S 560 V8 utilized an independent multi-link suspension system at both the front and rear axles. This suspension design provides a comfortable ride while maintaining precise handling. The suspension was often equipped with Mercedes-Benz’s AIRMATIC air suspension system, which allowed for adjustable ride height and damping settings. The braking system consisted of ventilated discs at all four corners, providing ample stopping power. Anti-lock braking system (ABS) was standard, along with electronic brake-force distribution and brake assist. The S 560 typically featured larger brake rotors and calipers compared to the lower-powered S-Class models, reflecting its higher performance capabilities. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The S 560 V8 was generally well-received by automotive critics, who praised its powerful engine, refined driving experience, and luxurious interior. It was often compared favorably to its rivals, such as the BMW 750i and Audi A8. Fuel economy was a point of discussion, with the S 560 achieving combined fuel consumption figures of 7.9-8.2 l/100 km (29.8-28.7 US mpg). While not exceptionally frugal, this was considered reasonable for a vehicle of its size and performance. Reliability was generally good, although the complex engine and transmission systems required regular maintenance. Compared to the S 450, the S 560 offered a significant performance upgrade, while the S 550 offered a similar level of performance but with a different engine configuration. The S 560 appealed to buyers who prioritized power and responsiveness without sacrificing luxury or comfort.

Technical Specifications

Legacy

The M176 engine, as found in the S 560 V8, has proven to be a relatively robust and reliable powerplant when properly maintained. Common issues, such as oil leaks and occasional turbocharger failures, are typically associated with neglected maintenance or high mileage. The 9G-TRONIC transmission has also demonstrated good reliability, although fluid changes are crucial for long-term durability. On the used car market, the S 560 V8 commands a premium over the lower-powered S-Class models, reflecting its increased performance and desirability. Well-maintained examples continue to be sought after by enthusiasts and buyers who appreciate the combination of luxury, performance, and technology that the S 560 V8 offers. Its sophisticated engineering and high-quality construction ensure that it remains a competitive and desirable luxury sedan for years to come.
