At first glance, the 2018 Mercedes-AMG C63 S sedan might not scream performance like some of its more aggressively styled counterparts. In a market where rivals often opt for increasingly flamboyant designs, Mercedes-AMG has taken a different approach with their ultimate C-Class sedan, favoring a more subtle and refined aesthetic. This design philosophy suggests a focus on substance over show, appealing to drivers who appreciate performance for its own sake, rather than for attracting attention. This understated confidence is part of the C63 AMG’s charm.
For those with a keen eye, however, the distinctions are clear. Car enthusiasts will immediately recognize the hallmarks of AMG engineering that set the C63 S apart from a standard C-Class. The unique front and rear bumpers, the assertive “V8 Biturbo” badging, and the large 19-inch wheels filling the wheel arches are all tell-tale signs. Add to this the slightly lower, more athletic stance and the distinctive rumble of the exhaust, and it becomes undeniably clear that this is no ordinary sedan. This is a machine built for serious performance.
AMG Performance Unleashed
The heart of the 2018 Mercedes-AMG C63 S lies under the hood, where a handcrafted 4.0-liter biturbo V8 AMG engine resides. Mercedes-AMG takes pride in the “one man, one engine” philosophy, and each engine is hand-built and signed by its individual craftsman. The engine bay is a showcase of performance engineering, with minimal plastic cladding, allowing a clear view of the “hot inside V” turbochargers nestled between the cylinder banks.
In standard C63 guise, this engine produces an impressive 469 horsepower and 479 pound-feet of torque. However, the C63 S variant takes performance even further, with meticulous tuning to deliver a potent 503 horsepower and 516 pound-feet of torque from the same formidable power plant. This enhanced output elevates the C63 S into a truly elite performance category.
Power is delivered to the rear wheels via a 7-speed AMG Speedshift multi-clutch transmission (MCT). Unlike a conventional automatic transmission, the MCT utilizes a wet startup clutch instead of a torque converter. This design choice results in quicker, more responsive gear changes and improved efficiency. In manual mode, the MCT boasts lightning-fast 0.1-second upshifts and rev-matched downshifts, enhancing driver engagement. It also enables more aggressive launches compared to traditional torque converter automatics and is engineered to handle the high torque output of the AMG V8.
Drivers can tailor the driving dynamics of the C63 S using the AMG Dynamic Select system, controlled by a wheel on the center console. This system offers Comfort, Sport, Sport+, and Race modes, each adjusting throttle response, transmission mapping, suspension damping, and traction control settings. The test vehicle was also equipped with an optional AMG Performance exhaust system, which amplifies the V8 soundtrack and reduces backpressure in Sport and Race modes, further intensifying the driving experience. For those who prefer granular control, each of these systems can also be adjusted individually via dedicated buttons on the center console.
Beyond the engine and transmission, the 2018 C63 S boasts significant chassis enhancements. The suspension is notably firmer than a standard C-Class, the wheel track is wider for increased cornering stability, and wider, stickier tires provide superior grip. These modifications work in concert to deliver the exceptional handling and performance that define the AMG driving experience.
The result is breathtaking acceleration. The C63 S achieves 0-60 mph in a mere 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 launch performance, the C63 S features a Race Start launch control system, easily activated by selecting Sport+ or Race mode and pulling both paddle shifters. Once engaged, simply apply the brake, floor the throttle, and release the brake for optimal acceleration.
Despite its immense power, the 2018 Mercedes-AMG C63 S remains remarkably composed, even when pushing the limits. On challenging roads, the car inspires confidence with its abundant grip, communicative steering, and progressive power delivery. The exhaust note is a thrilling V8 roar, distinct from the crackling and popping soundtracks of some competitors, like Jaguar’s 5.0-liter V8. The C63 S is a serious performance machine for drivers who appreciate focused and refined speed. It’s a car that makes high-speed driving feel effortlessly controlled and composed. However, the immense performance reserves are always accessible, allowing for thrilling bursts of acceleration and dynamic cornering when desired.
Everyday Comfort and Refinement
While the C63 S is undeniably a performance car, it also excels as a comfortable daily driver. Switching the Dynamic Select to Comfort mode 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 to a more relaxed and fuel-efficient program. Even in Comfort mode, the V8 engine retains a sense of effortless power, making highway cruising a pleasure. The C63 S moves through city streets with a refined presence, its deep growl serving as a subtle reminder of the performance lurking beneath.
The cabin of the C63 S is a testament to Mercedes-Benz’s commitment to luxury and comfort. It’s far from a stripped-down performance car, offering a level of refinement that is rare in this class. The interior is well-appointed with premium materials and comfortable seating, making it suitable for both spirited drives and daily commutes.
One feature that might require adjustment is the stop-start system. Designed to improve fuel economy by shutting off the engine at idle, it can feel somewhat intrusive in urban driving. While engine restart is rapid, the delay in transmission re-engagement and power delivery can lead to inconsistent accelerator pedal feel. Fortunately, the system can be easily deactivated with a button press for a more seamless driving experience in stop-and-go traffic.
In terms of fuel economy, the C63 S achieves a respectable 20 mpg combined (18 city/24 highway) when driven conservatively. This is comparable to rivals like the Alfa Romeo Giulia and BMW M3, despite their smaller turbocharged V6 engines, highlighting the efficiency of the AMG biturbo V8.
COMAND Infotainment and Cabin Tech
The interior of the C63 S is both stylish and functional. The test vehicle featured black Nappa leather trim, AMG carbon-fiber dashboard accents, silver metallic details, and striking saddle brown quilted Nappa leather seats. While the exterior design prioritizes understatement, the interior of the C63 S offers a more visually engaging and luxurious environment.
While the C63 S is based on the C-Class platform, and therefore doesn’t offer all the cutting-edge comforts of flagship models, it still provides a generous array of features. While massage seats are not available, options like color ambient lighting, cabin fragrance systems, hands-free trunk access, power closing, and a high-quality Burmester premium audio system enhance the overall experience. The Burmester system stands out not only for its exceptional sound quality but also for its visually appealing design, integrating seamlessly into the cabin.
The infotainment system in the C63 S utilizes an earlier generation of Mercedes-Benz’s COMAND system. While functional, it lags behind the newer, more intuitive systems found in models like the S-Class. The COMAND interface features a three-tier menu structure that can feel somewhat convoluted and less user-friendly compared to modern infotainment systems. The touchpad controller also lacks the natural feel and ease of use of more contemporary interfaces.
Despite these criticisms, the voice command system is effective, allowing for natural language input of addresses and destinations. The onboard navigation system is responsive and visually clear, and the dynamic route guidance, while not perfect, is comparable to other OEM traffic information systems.
However, coming from vehicles equipped with Mercedes-Benz’s latest MBUX system, the older COMAND system in the C63 S feels somewhat dated. While it performs its core functions adequately, it lacks the polish and user-friendliness of newer infotainment systems. An update to the infotainment system in future C-Class models would significantly enhance the overall user experience.
One peculiar aspect of the tech options is the separation of navigation and smartphone integration. Buyers must choose between the onboard navigation system (a $2,200 package) or Android Auto and Apple CarPlay connectivity ($300). The inability to have both is an unusual limitation, particularly for households with multiple drivers who may have different preferences. For most users, opting for the more affordable smartphone integration package is likely the more practical choice in this generation of COMAND.
Advanced Driver Assistance and Safety
The performance focus of the AMG C63 S does not compromise its safety and driver assistance features. It retains the full suite of safety technologies available in the standard C-Class sedan, including 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 ($2,250) significantly expands the ADAS capabilities, adding features like pedestrian-sensing forward collision alert with automatic emergency braking, a rear-collision safety system, lane-keeping assist with steering intervention, and enhanced blind-spot monitoring with collision avoidance steering assist and rear cross-traffic braking assist. This comprehensive package greatly enhances both safety and driver confidence.
The Driver Assistance Package also includes adaptive cruise control with stop-and-go functionality and low-speed steering assist, making commuting and highway driving more relaxed and less demanding. An additional option is the Surround View Camera system and Parktronic semi-autonomous parking assist ($1,090), which simplifies parking maneuvers, particularly in tight urban environments, and helps protect the expensive 19-inch AMG forged wheels from curb damage.
Overall Impression and Value
The 2018 Mercedes-AMG C63 Sedan starts at $66,100, while the higher-performance AMG C63 S Sedan begins at $73,700, excluding a $995 destination charge. With optional equipment and packages, the test vehicle reached an as-tested price of $90,500.
While the price point places the C63 S in the premium performance sedan segment, it delivers a compelling package of power, luxury, and everyday usability. For those seeking even greater value, the 362-horsepower Mercedes-AMG C43 sedan offers a more accessible entry point into the AMG family. However, the C63 S provides a significantly more potent and engaging driving experience that justifies its higher price.
The 2018 Mercedes-AMG C63 S sedan excels as a dual-purpose vehicle, offering both exhilarating performance and refined comfort. Its understated exterior design is a plus for those who prefer a less ostentatious performance car. Loaded with intelligent driver-assistance technologies, it also offers a high level of safety and convenience. The main drawbacks are the somewhat dated COMAND infotainment system and the occasionally intrusive stop-start system. Addressing these relatively minor shortcomings would elevate the C63 S to near-perfection in the sport sedan category.
In a competitive market segment, the C63 S faces strong rivals such as the BMW M3, which offers a slightly different balance of agility and comfort, and the Cadillac ATS-V, favored by drivers prioritizing track performance. Emerging competitors like the Alfa Romeo Giulia also present compelling alternatives. However, the 2018 Mercedes-AMG C63 S remains a top contender, offering a unique blend of German engineering, V8 power, and understated luxury that appeals to a discerning clientele.
