At first glance, the 2018 Mercedes-AMG C63 S sedan might not scream performance like some of its rivals. In a world where competitors are opting for increasingly aggressive designs, Mercedes-AMG has taken a different approach with their top-tier C-Class sedan, favoring a more subtle aesthetic. This design philosophy suggests a car built for the driver, rather than for attracting attention. For those in the know, this understated approach is part of the appeal.
To the discerning eye, the differences between this handcrafted AMG and a standard C-Class are immediately apparent. Enthusiasts will recognize the unique front and rear bumpers, the assertive “V8 Biturbo” badging, and the substantial 19-inch wheels that perfectly fill the wheel arches. The slightly lower, more athletic stance and the distinctive rumble of the exhaust hint at the special capabilities lurking beneath the surface. This 2018 Mercedes-AMG C63 S sedan is a wolf in sheep’s clothing, offering exhilarating performance with a touch of class.
AMG Performance Unleashed
The heart of the 2018 Mercedes-AMG C63 S lies under the hood, where a hand-built 4.0-liter biturbo V8 AMG engine proudly resides. Unlike engines hidden under layers of plastic, this powerplant is showcased, revealing the “hot inside V” turbochargers nestled between the cylinder banks. While the standard C63 delivers an impressive 469 horsepower and 479 pound-feet of torque, the C63 S variant takes performance to another level, boasting 503 horsepower and a staggering 516 pound-feet of torque from the same meticulously engineered engine.
This immense power is channeled to the rear wheels through a responsive 7-speed multiclutch automatic transmission (MCT). This transmission blends the smooth operation of a traditional automatic with the performance benefits of a wet startup clutch, replacing a conventional torque converter. The result is lightning-fast 0.1-second upshifts and rev-matched downshifts in manual mode. The MCT also facilitates harder launches compared to torque converter automatics and can manage greater torque loads than dual-clutch transmissions, making it an ideal match for the C63 S’s potent engine.
Drivers can tailor the driving dynamics of the 2018 Mercedes-AMG C63 S using the Dynamic Select wheel located on the center console. This system offers Comfort, Sport, Sport+, and Race modes, each precisely adjusting throttle response, transmission behavior, suspension damping, and traction control. The tested model was also equipped with an optional AMG Performance exhaust, which amplifies the V8’s roar and reduces backpressure in Sport and Race modes, further enhancing the auditory driving experience. For granular control, each of these systems can also be individually adjusted via dedicated buttons on the center console.
Beneath its refined exterior, the C63 S features a performance-tuned suspension, a wider wheel track for enhanced cornering stability, and wider, stickier tires compared to standard C-Class models. This combination of enhancements contributes to the car’s exceptional handling and confident roadholding.
The 2018 Mercedes-AMG C63 S sedan achieves a blistering 0-60 mph time of just 3.9 seconds (4.0 seconds for the standard C63) and reaches a top speed of 180 mph (155 mph for the C63). To maximize acceleration, the C63 S is equipped with a Race Start launch control system. Engaging this system is remarkably straightforward: simply select Sport+ or Race mode, pull and hold both paddle shifters, then firmly press the brake pedal, floor the accelerator, and release the brake for an optimal launch.
Balanced Performance and Daily Comfort
The 2018 Mercedes-AMG C63 S masterfully balances raw power with refined handling. While some high-performance cars can feel overwhelming, especially on challenging roads, the C63 S inspires confidence. Its abundant grip, communicative steering, and responsive throttle make managing its considerable power surprisingly intuitive. The V8 exhaust note is undeniably thrilling, but it maintains a sophisticated character, lacking the overt crackles and pops found in some competitors. The C63 S is a serious performance machine designed for drivers who appreciate both speed and composure. It transforms demanding roads into effortless drives, making high-speed driving feel remarkably controlled and comfortable.
However, this doesn’t mean the C63 S lacks playfulness. While its performance limits are exceptionally high, deliberate driver input can still induce controlled slides, especially in a track environment. To ensure confident stopping power, AMG has equipped the C63 S with large 14.2-inch performance disc brakes on all four corners, with even larger 15.4-inch front rotors for enhanced braking performance under demanding conditions.
Comfort and Refinement for Everyday Driving
Beyond its performance prowess, the 2018 Mercedes-AMG C63 S also excels as a comfortable daily driver. Switching the Dynamic Select mode to Comfort transforms the car’s character. The AMG Ride Control suspension softens, the optional AMG Performance exhaust quiets down, and the 7-speed automatic transmission shifts smoothly and unobtrusively. Even in Comfort mode, the V8 biturbo engine retains its effortless power, making highway cruising a relaxed experience. The sedan effortlessly navigates city streets, its deep growl serving as a subtle reminder of its underlying power.
This is not a stripped-out, track-focused machine. The C63 S cabin is designed for comfort and luxury, comparable to the best in its class.
The stop-start system, designed to improve fuel economy by shutting off the engine at idle, might be best disabled in regular driving. While engine restart is instantaneous upon releasing the brake pedal, the transmission re-engagement and power delivery can feel slightly delayed when pressing the accelerator. This subtle hesitation, likely engineered to smooth out the MCT’s engagement with the powerful V8, can result in an inconsistent accelerator pedal feel in urban driving. Fortunately, the system can be easily deactivated with a dedicated button.
In relaxed driving conditions, the 2018 Mercedes-AMG C63 S achieves a combined fuel economy of 20 mpg (18 city/24 highway mpg), which is competitive with rivals like the Alfa Romeo Giulia and BMW M3, despite their smaller turbocharged V6 engines.
COMAND Infotainment and Cabin Tech
The interior of the 2018 Mercedes-AMG C63 S is a testament to Mercedes-Benz’s commitment to luxury and craftsmanship. The test car featured black Nappa leather trim, AMG carbon-fiber dashboard accents, silver metallic detailing, and stunning saddle brown quilted Nappa leather seats. While the exterior design prioritizes subtlety, the C63 S’s interior makes a bold statement with its premium materials and sophisticated design.
While the C63 S, being based on the C-Class, forgoes some ultra-luxury features like massage seats, it still offers a wealth of desirable amenities. Ambient lighting, cabin fragrance system, hands-free trunk access with power closing, and a high-fidelity Burmester premium audio system are all available. The Burmester sound system not only sounds exceptional but also adds a visual touch of elegance to the cabin.
However, the infotainment system is an area where the 2018 Mercedes-AMG C63 S shows its age. It utilizes an older generation of Mercedes-Benz’s COMAND infotainment system. The system’s three-tier menu structure can feel convoluted and less intuitive compared to newer systems, making the 8.4-inch display feel somewhat cluttered. The COMAND touchpad controller also lacks the natural feel of more modern input methods.
Voice command functionality is a strong point, allowing for natural language input for navigation and other functions. The onboard navigation system delivers crisp maps and generally effective route guidance, although its traffic avoidance routing can sometimes be overly aggressive.
Despite its functionality, the COMAND system feels dated compared to the newer, more advanced systems found in models like the S-Class and the MBUX system. An updated infotainment system would significantly enhance the overall experience of the C63 S.
A peculiar tech limitation is the either/or choice between onboard navigation (part of a package) and smartphone integration (Android Auto and Apple CarPlay). It is not possible to have both simultaneously. This forces a somewhat inconvenient choice for users who desire both integrated navigation and smartphone connectivity. Opting for the less expensive smartphone integration might be the more practical choice for many buyers of this generation C63 S.
Driver Assistance and Safety
The performance focus of the AMG C63 S does not compromise its safety features. It retains the full suite of driver assistance technologies available on the standard C-Class sedan. This includes features ranging from an AMG head-up display to a comprehensive array of Advanced Driver Assistance Systems (ADAS).
Standard safety features include active LED headlamps with automatic high beams, driver-attention monitoring, blind-spot monitoring, a rearview camera, crosswind assist, and pre-collision alert systems. The optional Driver Assistance Package significantly expands these capabilities, adding pedestrian-sensing forward collision alert with automatic emergency braking, a rear-collision safety system, lane-keeping assist, and enhanced blind-spot monitoring with steering assist and rear cross-traffic braking.
The Driver Assistance Package also enhances the daily driving experience with adaptive cruise control featuring stop-and-go functionality and low-speed steering assist, making commutes more relaxed and safer.
An additional option package includes a surround-view camera system and Mercedes-Benz’s Parktronic semi-autonomous parking assist, which simplifies parallel parking maneuvers with automated steering. While the Parktronic interface could be more intuitive, it is a valuable feature for urban drivers and those concerned about protecting the optional 19-inch AMG forged wheels from curb damage.
The Complete Package
The 2018 Mercedes-AMG C63 S sedan, with its 503-horsepower V8, starts at $73,700 (excluding a $995 destination charge). The base 469-horsepower C63 starts at $66,100. With options and packages, the tested vehicle reached an as-tested price of $90,500.
For those seeking high performance without ostentation, the 2018 Mercedes-AMG C63 S is a compelling choice. It delivers exceptional power and composed handling while remaining comfortable and refined for daily driving. Its understated design is a distinct advantage for those who prefer subtle performance over aggressive styling. Loaded with intelligent driver assistance technology, the C63 S is also a smart choice. If it weren’t for the somewhat dated infotainment system and the occasionally intrusive stop-start system, the C63 S would be near-perfect in its class.
However, the C63 S faces strong competition. The BMW M3 offers a slightly different performance and comfort balance, emphasizing agility. The Cadillac ATS-V is another strong contender, particularly for drivers prioritizing track performance. Meanwhile, new rivals like the Alfa Romeo Giulia and even the Kia Stinger are also entering the fray, making the performance sedan segment more competitive than ever. Despite the competition, the 2018 Mercedes-AMG C63 S remains a top contender, blending power, luxury, and understated style in a compelling package.
