The Mercedes-Benz CLK 63 AMG Black Series, produced from April 2007 to May 2009, represents the highest-performance variant of the C209 CLK-Class coupe. Positioned as a limited-production, track-focused model, it was designed to offer a more visceral and engaging driving experience than the standard CLK 63 AMG.

Powertrain & Engine Architecture
The heart of the CLK 63 Black Series is the M156.982 6.2-liter naturally aspirated V8 engine. This engine, hand-built by AMG, was extensively modified from the standard CLK 63’s powerplant. Key changes included a revised crankshaft, connecting rods, and pistons, along with a higher compression ratio (11.3:1). The engine utilized a multi-port fuel injection system and a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. The result was an output of 507 horsepower at 6800 rpm and 464 lb-ft of torque at 5250 rpm. The engine’s longitudinal layout and rear-wheel drive configuration were standard for AMG models of this era.
The engine was paired with the AMG SPEEDSHIFT 7G-TRONIC automatic transmission. This seven-speed automatic was specifically tuned for quicker shifts and a more responsive feel. Drivers could select from Comfort, Sport, and Manual modes, with the Manual mode allowing for full control over gear selection via steering wheel-mounted paddle shifters. The transmission was crucial in managing the engine’s substantial power and delivering it effectively to the rear wheels.
Driving Characteristics
The CLK 63 Black Series offered a significantly more aggressive driving experience than the standard CLK 63. The increased power output, combined with the revised suspension and wider tires, resulted in exceptional acceleration and handling. The 0-60 mph sprint was dispatched in approximately 4.1 seconds, and the car was electronically limited to a top speed of 186 mph. The 7G-TRONIC transmission provided quick and precise shifts, enhancing the car’s responsiveness. However, the Black Series was not designed for ultimate comfort; the suspension was firm, and the ride could be harsh on uneven surfaces. Compared to the standard CLK 63, the Black Series felt noticeably more raw and engaging, prioritizing performance over refinement.
Equipment & Trim Levels
The CLK 63 Black Series was relatively sparsely equipped compared to other luxury coupes. The focus was on weight reduction and performance. Standard features included sport seats upholstered in leather and Alcantara, a sport steering wheel, and a premium audio system. Optional extras included carbon fiber interior trim, upgraded brakes, and a limited-slip differential. The interior was functional and driver-focused, with minimal distractions. The exterior featured aggressive styling cues, including wider fender flares, a prominent rear spoiler, and unique AMG wheels.
Chassis & Braking
The chassis of the CLK 63 Black Series underwent significant modifications to improve handling and stability. The suspension was lowered and stiffened, and wider track widths were implemented. The front suspension utilized McPherson struts with a coil spring and anti-roll bar, while the rear suspension featured a multi-link design with a stabilizer bar. Braking duties were handled by ventilated discs at all four corners, measuring 360x36mm at the front and 330x26mm at the rear. The ABS (Anti-lock braking system) was standard. The wider tires (265/30 R19 front, 285/30 R19 rear) provided increased grip and improved cornering performance.
Market Reception & Comparison
The CLK 63 Black Series was generally well-received by automotive critics. It was praised for its exceptional performance, engaging driving dynamics, and exclusivity. However, some critics noted its firm ride and relatively sparse interior. Compared to the standard CLK 63, the Black Series offered a significantly more focused and rewarding driving experience, but at the expense of comfort. Compared to other high-performance coupes of the era, such as the BMW M3 Coupe, the CLK 63 Black Series offered a unique blend of power, luxury, and exclusivity. Fuel economy was predictably poor, reflecting the car’s high-performance nature.
Legacy
The CLK 63 Black Series remains a highly sought-after collector’s car. Its limited production run and exceptional performance have contributed to its increasing value. The M156 engine, known for its robust construction and naturally aspirated character, has proven to be relatively reliable, although maintenance costs can be significant. Today, the CLK 63 Black Series is appreciated by enthusiasts for its raw driving experience and its status as one of the last of the naturally aspirated, high-performance AMG coupes. Well-maintained examples command premium prices in the used car market.
