The 2009 Mercedes-Benz C63 AMG arrived on the scene not just as another variant of the C-Class, but as a statement. It was Mercedes-Benz’s bold declaration in the compact performance sedan segment, challenging rivals with a blend of raw power, sophisticated technology, and unmistakable AMG DNA. Building upon the already impressive C-Class platform, the C63 AMG turned up the intensity to eleven, delivering an experience that was both thrilling on the track and refined on the road. This wasn’t just about straight-line speed; it was about crafting a complete performance package that engaged all senses.
The Heart of the Beast: Handcrafted 6.2L V8 Engine
At the core of the 2009 Mercedes-Benz C63 AMG resided a monstrous 6.2-liter naturally aspirated V8 engine, a powerplant that distinguished itself from the growing trend of forced induction at the time. This wasn’t an off-the-shelf engine; each one was meticulously hand-built by a single AMG technician, a testament to the brand’s commitment to craftsmanship and performance. This dedication is visually highlighted by a plaque bearing the signature of the master engine builder, proudly displayed on the engine itself.
This potent V8 churned out an impressive 451 horsepower and a staggering 443 lb-ft of torque. The result was explosive acceleration, propelling the C63 AMG from 0 to 60 mph in a mere 4.3 seconds. The engine’s responsiveness was immediate, delivering a surge of power across the rev range. Unlike turbocharged engines that might require a moment to spool up, the 6.2L V8 offered instant gratification, making every press of the accelerator a visceral experience. The engine’s robust construction, featuring a silicon-aluminum alloy and friction-reducing cylinder coating, ensured both performance and durability.
Dynamic Performance and Handling Prowess
The 2009 Mercedes-Benz C63 AMG wasn’t solely about brute force; it was engineered for dynamic handling. The AMG-tuned suspension, with a 1.4-inch wider front track compared to the standard C-Class, provided enhanced stability and cornering grip. While the ride was firmer, as expected in a performance vehicle, it remained compliant enough for daily driving, striking a balance between track readiness and road comfort.
The AMG Speedshift Plus 7-speed automatic transmission was specifically calibrated to complement the V8 engine’s character. While purists might have longed for a manual option, the automatic proved to be a capable partner, offering rapid gear changes and intelligent shift logic. In Sport mode, the transmission aggressively downshifted during braking and held gears through corners, anticipating the driver’s needs on a spirited drive. For those seeking more control, manual mode allowed gear selection via the gear lever or steering wheel-mounted paddles, offering shifts that were notably quicker than in Drive mode. While not a dual-clutch system, the AMG Speedshift Plus delivered performance-oriented shifts that enhanced the driving experience.
The C63 AMG’s handling was sharp and responsive. It offered a playful rear-wheel-drive character, allowing for controlled drifts when desired, particularly with the Electronic Stability Program (ESP) in Sport mode. While the ESP system would intervene to maintain stability, the Sport mode allowed for more driver involvement and a greater sense of connection to the car’s dynamics, without completely disabling safety nets.
Cabin Technology and Refinement
Stepping inside the 2009 Mercedes-Benz C63 AMG revealed a cabin that blended sporty cues with Mercedes-Benz’s signature luxury. The flat-bottom AMG steering wheel and AMG-specific instrument cluster immediately signaled the car’s performance intentions. Sport seats with prominent side bolsters provided excellent support during enthusiastic driving, holding occupants firmly in place.
While the overall interior design was consistent with the C-Class, the C63 AMG received unique touches to elevate its sporty character. The predominantly black interior with silver accents created a sophisticated yet purposeful ambiance, avoiding overly flamboyant styling. The Mercedes-Benz COMAND interface, controlled via a rotary knob and buttons on the center console, managed the car’s infotainment functions. Quick access buttons for navigation, audio, and phone, along with a keypad, were conveniently placed on the instrument panel.
The navigation system, utilizing hard-drive storage, offered quick route calculations and clear map displays, including lane guidance on highways. While it lacked real-time traffic or weather updates, features becoming more common at the time, its core functionality was robust. The Music Register feature provided 4GB of hard drive space for music storage, supplemented by a six-disc CD changer with MP3 compatibility, Sirius satellite radio, and iPod integration (although functionality might have varied in early production models as noted in the original review).
The Harmon Kardon audio system was a standout feature, delivering exceptional sound quality. With 12 speakers powered by a 320-watt amplifier, the system produced rich, clear audio with impressive separation and depth. The Bluetooth phone system paired easily with compatible devices and allowed for contact import, enhancing hands-free connectivity.
The Sonic Symphony of the AMG V8
One of the most captivating aspects of the 2009 Mercedes-Benz C63 AMG was its exhaust note. The 6.2L V8 produced a distinctive and aggressive sound, a deep baritone rumble that transformed into a ferocious bark under acceleration. As described in the original review’s sound-off test, the C63 AMG’s engine note was raw and visceral, a stark contrast to the more refined and muted sound of competitors like the Maserati GranTurismo. The AMG V8’s sound was a key element of its character, announcing its presence with authority and contributing significantly to the overall driving thrill.
Pros and Cons: A Balanced Perspective

Standing Against the Competition
The 2009 Mercedes-Benz C63 AMG directly targeted the BMW M3, a long-standing benchmark in the performance sedan segment. Both cars offered comparable levels of performance and driver engagement. The C63 AMG countered the M3’s high-revving engine with a different approach – raw, low-end torque and a thunderous V8 soundtrack. While the M3 offered an available dual-clutch transmission (later in its generation), the C63 AMG relied on its refined and responsive automatic. In terms of cabin technology, both cars were well-equipped for their time, with the C63 AMG boasting a particularly impressive audio system. Alternatives like the Nissan GT-R offered even greater performance, but the C63 AMG prioritized a balance of performance, luxury, and daily usability that resonated with a specific type of enthusiast.
Conclusion: A Timeless AMG Icon
The 2009 Mercedes-Benz C63 AMG solidified its place as a performance icon. It wasn’t just a fast car; it was a statement of intent, a demonstration of AMG’s ability to infuse raw power with German engineering and luxury. Its naturally aspirated 6.2L V8 engine, a rarity in its class, delivered a driving experience that was both visceral and unforgettable. While fuel economy was a compromise, the C63 AMG offered a compelling package of performance, technology, and unmistakable AMG character. For enthusiasts seeking a performance sedan with a soul, the 2009 Mercedes-Benz C63 AMG remains a highly desirable and timeless choice.
