At first glance, the 2018 Benz C63 AMG sedan might not scream performance like some of its rivals. In a world where competitors are opting for increasingly aggressive styling, Mercedes-AMG has taken a different approach, keeping their ultimate C-Class sedan relatively subtle. This design choice speaks volumes, suggesting that the C63 AMG is built for drivers who appreciate raw power and refined performance without needing to shout about it. This understated aggression is part of its charm, appealing to those who value substance over show.
For those in the know, however, the 2018 Benz C63 AMG is instantly recognizable as something truly special. Enthusiasts will spot the unique AMG-specific front and rear bumpers, the assertive “V8 Biturbo” badging on the fenders, and the large 19-inch AMG wheels that perfectly fill the wheel arches. The slightly lowered, more athletic stance and the distinctive burble of the AMG exhaust further hint at the immense performance lurking beneath the surface. These subtle cues differentiate the C63 AMG from the standard C-Class models, signaling its high-performance pedigree.
AMG Performance: Heart of a Beast
The true essence of the 2018 Benz C63 AMG 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 this engine is a testament to that. Unlike many modern engines hidden under layers of plastic, the AMG V8 is proudly displayed, showcasing the “hot inside V” turbocharger configuration nestled between the cylinder banks. The standard C63 delivers a formidable 469 horsepower and 479 pound-feet of torque, but the C63 S variant elevates performance even further, boasting an impressive 503 horsepower and 516 pound-feet of torque from the same meticulously engineered powerplant.
This immense power is channeled to the rear wheels through a responsive 7-speed AMG SPEEDSHIFT MCT (Multi-Clutch Transmission). This transmission blends the smooth operation of a conventional automatic with the performance benefits of a dual-clutch system. Utilizing a wet startup clutch instead of a traditional torque converter, the MCT delivers lightning-fast 0.1-second upshifts and precise rev-matched downshifts in manual mode. It also enables more aggressive launches and can handle the high torque output of the V8 engine more effectively than a typical dual-clutch transmission in this application.
Drivers can tailor the driving dynamics of the 2018 Benz C63 AMG using the AMG DYNAMIC SELECT system, controlled via a rotary dial on the center console. This system offers Comfort, Sport, Sport+, and Race modes, each meticulously calibrating throttle response, transmission mapping, suspension damping, and traction control settings. The tested model was also equipped with an optional AMG Performance exhaust system, which amplifies the V8’s soundtrack in Sport and Race modes, creating a more visceral driving experience. For those who prefer individual customization, each of these systems can also be adjusted independently using dedicated buttons on the center console.
Beyond the engine and transmission, the 2018 Benz C63 AMG features a comprehensively upgraded chassis. The suspension is notably firmer than standard C-Class models, the wheel track is widened for enhanced cornering stability, and wider, stickier tires provide superior grip. These enhancements work in concert to deliver exceptional handling and responsiveness.
The result is blistering acceleration, with the C63 S model achieving 0-60 mph in a mere 3.9 seconds (4.0 seconds for the standard C63) and reaching a top speed of 180 mph (155 mph for the C63). To aid in achieving these figures, the C63 AMG features AMG RACE START, a launch control system that’s remarkably easy to engage. Simply select Sport+ or Race mode, pull and hold both paddle shifters, depress the brake pedal, floor the accelerator, and release the brake for maximum acceleration.
Despite its raw power, the 2018 Benz C63 AMG remains remarkably composed, even when pushing its limits. On challenging roads, the car inspires confidence with its abundant grip, communicative steering, and progressive power delivery. The exhaust note is a deep, satisfying roar, distinct from the crackling and popping found in some competitors. The C63 AMG is a serious performance machine for drivers who appreciate precision and control. It transforms demanding driving scenarios into effortless displays of capability.
While incredibly capable, the 2018 Benz C63 AMG is not solely focused on track performance. It allows for playful driving dynamics, but its high limits require deliberate effort to reach, making it manageable and enjoyable on public roads. For those seeking to explore the car’s full potential, the AMG engineers have equipped it with substantial braking power: 14.2-inch performance disc brakes all around, with even larger 15.4-inch front rotors on the C63 S, ensuring confident stopping power even under demanding conditions.
Comfort and Daily Drivability
While the 2018 Benz C63 AMG is a performance powerhouse, 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 program. Even in Comfort mode, the V8 engine retains its effortless power, making highway cruising a breeze. The C63 AMG navigates city streets with a refined presence, its subtle growl hinting at the power within.
The cabin of the 2018 Benz C63 AMG is far from a stripped-down race car environment. It offers a level of comfort and luxury befitting the Mercedes-Benz brand. The interior is well-appointed with high-quality materials and comfortable seating, making it suitable for everyday use.
However, the stop-start system, designed to improve fuel efficiency, can be somewhat intrusive in daily driving. While it restarts the engine quickly, the delay in re-engaging the transmission can result in inconsistent accelerator pedal response in stop-and-go traffic. Fortunately, the system can be easily deactivated with a button press.
Fuel economy is respectable for a high-performance V8, with the C63 S achieving a combined EPA rating of 20 mpg (18 city/24 highway). This is comparable to rivals with smaller turbocharged V6 engines, highlighting the efficiency of the AMG biturbo technology.
COMAND Infotainment and Cabin Technology
The interior of the 2018 Benz C63 AMG is a blend of sporty and luxurious elements. 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 is understated, the interior design makes a bolder statement, creating a premium and sporty ambiance.
While the 2018 Benz C63 AMG offers numerous luxury features, it’s important to note that it utilizes an older generation of Mercedes-Benz’s COMAND infotainment system. While functional, this system is not as intuitive or visually appealing as the newer MBUX system found in newer Mercedes-Benz models. The COMAND system features a multi-tiered menu structure that can feel somewhat cluttered and less user-friendly compared to modern infotainment interfaces. The touchpad controller also may not feel as natural to use as touchscreen interfaces.
Voice command functionality is a strong point, allowing for natural language input for navigation and other functions. The onboard navigation system is responsive and visually clear, although the dynamic route guidance may occasionally suggest less-than-optimal routes.
Despite its functionality, the COMAND system in the 2018 Benz C63 AMG feels dated compared to newer systems, particularly the MBUX system. Prospective buyers should be aware of this aspect, especially if in-car technology is a high priority.
A peculiar limitation of the infotainment system is the either/or choice between onboard navigation and smartphone integration (Apple CarPlay and Android Auto). Buyers must choose one or the other, as both cannot be equipped simultaneously. This is an unusual constraint, particularly in households with multiple drivers who may have different preferences. For most users, opting for the less expensive smartphone integration may be the more practical choice.
Driver Assistance and Safety Systems
The 2018 Benz C63 AMG does not compromise on safety, offering a comprehensive suite of driver assistance and safety technologies. All the driver-aid features available on the standard C-Class sedan are also available on the AMG model, including an AMG head-up display and numerous 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 adds a significant array of ADAS features, enhancing both safety and driving convenience. This package includes pedestrian-sensing forward collision alert with automatic braking, a rear-collision safety system, lane-keeping assist, and more sophisticated blind-spot monitoring with steering assist and rear cross-traffic braking assist.
The Driver Assistance Package also enhances the commuting experience with adaptive cruise control that functions in stop-and-go traffic and includes low-speed steering assist. An additional option package adds a surround-view camera system and Mercedes-Benz’s PARKTRONIC semi-autonomous parking assist, which can automatically steer the car into parallel parking spaces. While the PARKTRONIC interface could be more intuitive, it is a valuable feature, especially for urban drivers.
Overall Impression: A Potent and Refined Package
The 2018 Benz C63 AMG sedan starts at $66,100 for the 469-horsepower model, while the more powerful 503-horsepower C63 S begins at $73,700, excluding a $995 destination charge. With options and packages, the tested vehicle reached an as-tested price of $90,500.
The 2018 Benz C63 AMG is a compelling package, offering a blend of raw V8 power, refined handling, and surprising daily comfort. Its understated exterior design will appeal to those who prefer performance without ostentation. The C63 AMG is both a thrilling performance car and a comfortable and well-equipped luxury sedan. The main drawback is the older COMAND infotainment system, which feels dated compared to contemporary systems. The stop-start system can also be somewhat clunky in urban driving.
Despite these minor shortcomings, the 2018 Benz C63 AMG remains a top contender in the performance sedan segment. It competes directly with the BMW M3, offering a different but equally compelling driving experience. The Cadillac ATS-V is another strong competitor, prioritizing track performance, while the Alfa Romeo Giulia and Kia Stinger offer alternative options in the segment. For buyers seeking a powerful, refined, and understated performance sedan with a glorious V8 engine, the 2018 Benz C63 AMG is an excellent choice.
