INTRODUCTION
The C 63 S Coupe, part of the C205 series facelifted in 2018, represents a significant step up in performance from the standard C-Class Coupe. Built on the rear-wheel-drive platform (though 4MATIC all-wheel drive was available in some markets), it aimed to deliver a thrilling driving experience without sacrificing the luxury and refinement expected from a Mercedes-Benz. The facelift brought updated styling cues, enhanced technology, and refinements to the already potent powertrain. This model sat at the very top of the C-Class Coupe range, offering a more focused and aggressive experience than the C 43 AMG variant.
Powertrain & Engine Architecture
The heart of the C 63 S Coupe is the M177.980 4.0-liter twin-turbocharged V8 engine. This engine, hand-assembled in Affalterbach, Germany, utilizes a ‘hot-vee’ configuration, meaning the turbochargers are located within the V of the engine, resulting in a more compact design and improved responsiveness. The engine employs direct fuel injection and features a sophisticated valvetrain with continuously variable camshaft adjustment. The MCT (Multi Clutch Technology) 9-speed automatic transmission is a key component, replacing the traditional torque converter with a wet multi-plate clutch. This design allows for faster and more direct gear changes. The transmission is tuned for performance, with quick shifts and a responsive feel.
Driving Characteristics
The C 63 S Coupe delivers a truly exhilarating driving experience. The 510 horsepower and 700 Nm (516 lb-ft) of torque provide immense acceleration, with a 0-60 mph time of just 3.7 seconds. The MCT transmission contributes to this performance, offering rapid gear changes and a direct connection to the engine. While the standard C-Class Coupes prioritize comfort, the C 63 S is noticeably firmer, with a more focused suspension setup. The rear-wheel drive configuration allows for a playful and engaging driving experience, but also requires respect and skill, particularly in adverse conditions. Compared to the C 43 AMG, the C 63 S offers significantly more power and a more aggressive character. The higher output and more responsive transmission make it a more rewarding choice for driving enthusiasts.
Equipment & Trim Levels
The C 63 S Coupe came standard with a comprehensive list of features, befitting its flagship status. Interior appointments included high-quality leather upholstery, AMG sport seats, and a flat-bottom steering wheel. Standard technology included the Mercedes-Benz COMAND infotainment system with a large central display, navigation, and a premium sound system. Optional extras included carbon fiber trim, performance exhaust systems, and advanced driver-assistance features like adaptive cruise control and lane-keeping assist. The interior design was largely consistent with other C-Class Coupes, but with unique AMG-specific touches to emphasize its performance credentials.
Chassis & Braking
The C 63 S Coupe features a sophisticated chassis designed to handle the engine’s immense power. It utilizes an independent multi-link suspension at both the front and rear, tuned for performance and handling precision. Larger brakes, with ventilated discs at all four corners, provide ample stopping power. The braking system is enhanced by ABS (Anti-lock Braking System) and other electronic stability control systems. The car also features an AMG-tuned steering system, providing precise and responsive steering feel. Compared to lower-spec C-Class Coupes, the C 63 S benefits from a stiffer chassis and more aggressive suspension tuning.
Market Reception & Comparison
The C 63 S Coupe was generally well-received by automotive critics, praised for its powerful engine, engaging driving dynamics, and luxurious interior. However, some reviewers noted its firm ride and relatively high fuel consumption. Compared to its rivals, such as the BMW M8 Competition and Audi RS5, the C 63 S offered a compelling blend of performance and luxury. Its fuel economy, while not exceptional, was comparable to other high-performance coupes in its class. Reliability reports have been generally positive, although the complexity of the engine and transmission means that maintenance costs can be higher than for more mainstream models.
Legacy
The C 63 S Coupe represents a high point in the evolution of the C-Class Coupe. Its potent V8 engine and sophisticated technology have cemented its place as a desirable performance car. On the used car market, these models hold their value well, attracting enthusiasts seeking a thrilling and refined driving experience. While newer models have adopted hybrid technology, the C 63 S Coupe remains a popular choice for those who appreciate the raw power and character of a traditional V8 engine. The M177 engine itself is considered a robust and capable unit, though regular maintenance is crucial to ensure long-term reliability.
