2018-2021 Mercedes-Benz C-class (W205 facelift ) AMG C 63 S V8 (510 Hp) MCT

The Mercedes-Benz C 63 S, specifically in its W205 facelift iteration produced from 2018 to 2021, represents the high-performance pinnacle of the C-Class range. Positioned as the flagship model, it catered to enthusiasts seeking exhilarating performance combined with a degree of luxury and practicality. This variant distinguished itself with a hand-built AMG 4.0-liter twin-turbocharged V8 engine, delivering 510 horsepower and 700 Nm (516 lb-ft) of torque, paired with a sophisticated 9-speed MCT (Multi Clutch Technology) automatic transmission. The C 63 S aimed to compete directly with rivals like the BMW M3/M4 and the Audi RS 5.

Technical Specifications

INTRODUCTION

The W205 Mercedes-Benz C-Class, launched in 2014 and facelifted in 2018, represented a significant step forward in terms of technology, refinement, and driving dynamics for the German automaker. The AMG C 63 S, introduced as the performance leader, built upon this foundation with a potent engine and track-focused enhancements. The 2018 facelift brought styling updates, revised interior features, and further refinement to the AMG model. It was positioned above the ‘standard’ C 63, offering increased power, more aggressive styling, and a more focused driving experience.

Powertrain & Engine Architecture

The heart of the C 63 S is the M177.980 4.0-liter twin-turbocharged V8 engine. This engine, a departure from the naturally aspirated 6.2-liter V8 used in previous C 63 models, utilizes direct injection and hot-inner-V turbocharger technology. The ‘hot-V’ configuration places the turbochargers inside the V of the engine, reducing exhaust manifold length and improving throttle response. Each turbocharger features ceramic turbine blades for reduced inertia. The engine produces 510 horsepower at 5500-6250 rpm and a substantial 700 Nm (516 lb-ft) of torque between 2000 and 4500 rpm.

The engine is mated to the AMG SPEEDSHIFT MCT 9-speed automatic transmission. Unlike a traditional torque converter automatic, the MCT transmission uses a wet multi-plate clutch pack instead of a torque converter, resulting in faster and more direct gear changes. The transmission offers a variety of driving modes, including Comfort, Sport, Sport+, Race, and Individual, allowing the driver to tailor the shift points and responsiveness to their preferences. A launch control system is also included for optimal acceleration from a standstill.

Driving Characteristics

The C 63 S delivers a truly exhilarating driving experience. The combination of the powerful V8 engine and the quick-shifting MCT transmission results in blistering acceleration – 0 to 60 mph in just 3.8 seconds. The engine’s broad torque curve provides effortless power throughout the rev range, making it equally capable on the road and the track. The exhaust note is characteristically aggressive, particularly in Sport and Race modes. The suspension, tuned for performance, provides excellent body control and minimizes roll during cornering. While comfortable enough for daily driving, the C 63 S prioritizes performance over outright comfort, with a firmer ride than lesser C-Class models.

Equipment & Trim Levels

The C 63 S came standard with a comprehensive list of features, including AMG sport seats, a performance steering wheel, AMG body styling, and a host of driver assistance systems. Interior appointments typically included Nappa leather upholstery, carbon fiber trim, and brushed aluminum accents. Optional extras included a panoramic sunroof, a Burmester surround sound system, and advanced driver assistance packages. The C 63 S was generally offered with minimal standalone options, as it was already comprehensively equipped from the factory.

Chassis & Braking

The C 63 S features an AMG-tuned suspension system, with adaptive dampers and stiffer springs compared to standard C-Class models. The front suspension utilizes a three-link design, while the rear features a multi-link setup. Large ventilated and perforated brake discs (360mm front and rear) provide ample stopping power, and the braking system includes ABS, ESP, and a brake assist function. The car also features an electronic limited-slip differential to improve traction and handling during cornering.

Market Reception & Comparison

The AMG C 63 S was widely praised by automotive critics for its performance, handling, and luxurious interior. It was consistently ranked among the top performers in its segment, often lauded as the benchmark for high-performance compact executive cars. Compared to the standard C 63, the ‘S’ model offered a noticeable increase in power and a more aggressive driving experience. Fuel economy, unsurprisingly, was not a strong point, with combined figures around 23.8 US mpg. Reliability was generally good, although the complex engine and transmission systems could potentially require more expensive maintenance than simpler alternatives.

Legacy

The W205 C 63 S represents a significant milestone in the evolution of the AMG C-Class. Its potent engine, advanced transmission, and track-focused chassis set a new standard for performance in the compact executive segment. On the used car market, these models hold their value well, particularly well-maintained examples with low mileage. The M177 engine, while complex, has proven to be relatively robust when properly maintained, making the C 63 S a desirable option for enthusiasts seeking a high-performance luxury sedan.
