The Mercedes-Benz S-Class AMG S 63, produced between 2013 and 2017 as part of the W222 generation, represents the high-performance variant of the flagship S-Class sedan. Positioned as the top-tier performance model within the W222 lineup, it offered a significant step up in power and handling compared to the standard S-Class models and the more efficiency-focused variants. The AMG S 63 catered to buyers seeking the ultimate combination of luxury, performance, and prestige, establishing itself as a benchmark in the ultra-luxury performance sedan segment.
Powertrain & Engine Architecture
At the heart of the AMG S 63 lies the M157.985 5.5-liter V8 engine. This engine is a twin-turbocharged, direct-injection powerplant, meticulously engineered by Mercedes-AMG. The engine boasts a displacement of 5461 cm³ (333.25 cubic inches) and utilizes a compression ratio of 10:1. The direct injection system ensures precise fuel delivery, optimizing combustion efficiency and contributing to the engine’s impressive power output. The twin turbochargers, along with an intercooler, force more air into the engine, significantly boosting horsepower and torque. The engine is longitudinally mounted in the front of the vehicle.
The AMG S 63 is exclusively paired with the AMG SPEEDSHIFT MCT 7-speed automatic transmission. This transmission isn’t a traditional torque-converter automatic; instead, it employs a wet multi-plate clutch pack instead of a torque converter. This design provides faster and more direct gear changes, enhancing the driving experience and contributing to improved performance. The MCT transmission features selectable driving modes, allowing the driver to tailor the shift points and responsiveness to their preferences. These modes range from Comfort, offering smooth and refined shifts, to Sport and Sport+, which prioritize aggressive downshifts and quicker acceleration.
Engine Specifications
The M157.985 engine delivers a maximum power output of 585 horsepower (Hp) at 5500 rpm and a substantial 900 Newton-meters (663.81 lb-ft) of torque available from 2250 to 3750 rpm. This translates to a power-to-liter ratio of 107.1 Hp/l. The engine requires 8.5 liters (8.98 US quarts / 7.48 UK quarts) of engine oil, adhering to specific Mercedes-Benz specifications, and 11.5 liters (12.15 US quarts / 10.12 UK quarts) of coolant.
Driving Characteristics
The AMG S 63 delivers a driving experience markedly different from the standard S-Class. The substantial power and torque, combined with the quick-shifting MCT transmission, result in exhilarating acceleration. The car can achieve 0 to 60 mph in approximately 3.9 seconds. The rear-wheel drive configuration, coupled with a sophisticated suspension system, provides excellent handling and stability, although it requires a skilled driver to fully exploit its capabilities. The AMG-tuned suspension, featuring adaptive damping, minimizes body roll during cornering and provides a comfortable ride in everyday driving conditions. The selectable driving modes allow the driver to adjust the suspension stiffness and steering weight to suit their preferences.
Compared to other S-Class variants, the AMG S 63 offers a more aggressive and engaging driving experience. The standard S-Class models prioritize comfort and refinement, while the AMG S 63 emphasizes performance and driver involvement. The higher-output nature of the AMG engine also results in increased fuel consumption, a trade-off for the added performance.
Equipment & Trim Levels
The AMG S 63 came standard with a comprehensive array of luxury and performance features. Interior appointments included premium leather upholstery, AMG sport seats with enhanced bolstering, and unique AMG badging throughout the cabin. The dashboard featured AMG-specific instrumentation and trim elements. Standard equipment also included a high-end Burmester surround sound system, a panoramic sunroof, and advanced driver-assistance systems such as adaptive cruise control, lane-keeping assist, and blind-spot monitoring.
Numerous optional extras were available, allowing buyers to further personalize their vehicles. These included carbon fiber trim, upgraded leather options, rear-seat entertainment systems, and a head-up display. The AMG Performance Package added even more aggressive styling elements, increased engine power (in some markets), and enhanced braking performance.
Chassis & Braking
The AMG S 63 utilizes an independent multi-link suspension system at both the front and rear axles. This suspension design provides a superior ride quality and handling characteristics compared to simpler suspension setups. The suspension is electronically controlled, allowing for adjustable damping rates to optimize comfort or performance. The car features ventilated disc brakes at all four corners, providing ample stopping power. The braking system is enhanced by ABS (Anti-lock Braking System) and other electronic stability control systems.
The curb weight of the AMG S 63 is 1970 kg (4343.11 lbs), with a maximum weight of 2700 kg (5952.48 lbs) and a maximum load capacity of 730 kg (1609.37 lbs). The vehicle’s weight distribution is carefully balanced to optimize handling and stability.
Market Reception & Comparison
The AMG S 63 was widely praised by automotive critics for its exceptional performance, luxurious interior, and advanced technology. It was consistently ranked among the top performers in its class, competing with other high-performance luxury sedans such as the Porsche Panamera Turbo and the BMW 760i. Critics noted the car’s impressive acceleration, precise handling, and comfortable ride. However, some reviewers pointed to the high price tag and increased fuel consumption as potential drawbacks.
Compared to other S-Class trims, the AMG S 63 offered a significantly higher level of performance but at the expense of fuel economy. The standard S-Class models, with their smaller engines and more comfort-oriented tuning, achieved better fuel efficiency. The S 550, for example, offered a balance of performance and efficiency, while the S 350 prioritized fuel economy.
