Mercedes-Benz CLK63 AMG Black Series (W209) Buyers Guide

For decades, Mercedes-Benz has collaborated with AMG to craft high-performance versions of their vehicles across the entire model lineup, from the C-Class to the S-Class. Each AMG model subtly exudes aggression, power, luxury, and authority. If you recognize an AMG, it’s almost guaranteed to catch your attention. Adding to their appeal is the relative rarity of AMG models, which are far less common than BMW’s M cars.

Mercedes-Benz has long been a dominant force in motorsports, from DTM to Formula 1, and even extending beyond racing with their support and pace cars. Drawing from their extensive on-track engineering expertise, Mercedes and AMG decided to create the ultimate street car: the Black Series.

To date, five Mercedes-Benz AMG models have earned the prestigious Black Series badge: the SLK55, CLK63, SL65, C63, and SLS. While the SLK55 AMG Black Series was technically the first to bear the badge, it wasn’t available in the United States. The CLK63 AMG Black Series, launched in 2008, marked a radical departure from traditional AMG DNA, stunning enthusiasts and critics alike.

AMG had always taken a unique approach to performance—focusing on raw power without always pairing it with advanced handling upgrades. The CLK63 AMG Black Series changed that paradigm, introducing race-inspired enhancements like wider fenders, increased power, extensive use of carbon fiber, and an upgraded suspension system that significantly improved handling. Think of it as AMG’s answer to icons like the BMW M3 CSL, Dodge Viper ACR, and Porsche GT3.

Seeing a CLK63 AMG Black Series in person is a rare treat, made even more special by its limited production—only 367 units were brought to the United States. This rarity makes the Black Series harder to spot than even a Bugatti Veyron.

The first thing you’ll notice about the CLK63 AMG Black Series is its dramatic wide-body design, featuring flared front and rear fenders. Beneath those aggressive arches sit 19-inch forged aluminum wheels wrapped in 265/30 front and 285/30 rear tires, ensuring maximum grip. Braking power comes from the massive 6-piston front and 4-piston rear calipers paired with larger composite rotors.

If the fender flares don’t grab your attention, the liberal use of carbon fiber and functional vents surely will. Up front, carbon fiber cooling ducts dominate the bumper, while side vents proudly display the 6.3L AMG badge. The rear view is equally striking, with a carbon fiber lip spoiler and a diffuser that directs air to a differential cooler. Quad exhaust tips and fins complete the aggressive look.

Under the hood lies a 6.2L naturally aspirated V8, the hallmark of AMG’s performance lineup at the time. For the Black Series, this engine was tuned to produce over 500 horsepower and 478 lb-ft of torque—surpassing the typical AMG power range of 450–475 HP. The power is channeled through a 7G-Tronic Speedshift automatic transmission with paddle shifters and a limited-slip differential.

Despite its performance focus, the transmission remains a traditional automatic. The result? A 0-60 mph sprint in under 4 seconds and a quarter-mile time under 12 seconds. However, the Black Series isn’t just about straight-line speed—it shines brightest on the racetrack.

The CLK63 AMG Black Series surprises with its dramatically improved handling, thanks to chassis and suspension upgrades. Weight reduction, while modest at around 100 lbs, is complemented by increased stiffness and rigidity. Reinforcements include large chassis braces under the hood and trunk, while adjustable coilovers allow for fine-tuned ride height adjustments.

Inside, the focus on performance continues. Carbon fiber dominates the cabin, and the rear seats have been removed to save weight. Although back seats are technically still present, they’re not equipped with seatbelts and are not intended for use. The front seats, though excellent in support and bolstering, lack electronic adjustments, and Europe received even more hardcore bucket seats.

The push-button start and stubby shift lever adds unique touches, while the flat-bottom leather steering wheel, inspired by F1, feels perfectly weighted.

Buying a CLK63 AMG Black Series was straightforward, as there were no packages and only one optional feature—an iPod connector. The available colors were Mars Red, Arctic White, Iridium Silver, Black, and Obsidian Black (yes, two black options).

The CLK63 AMG Black Series stood as a beacon of what AMG could achieve, giving stiff competition to the likes of the Porsche GT3, BMW M3 CSL, and the Audi RS5.

Driving Experience

The moment you press the push-button start and the M156 V8 roars to life, it’s clear that you’re about to experience something truly special. On cold starts, the CLK63 AMG Black Series produces one of its most unforgettable symphonies—pops, snaps, and cracks echoing in a glorious celebration of raw power.

Mercedes-Benz kept the driving modes straightforward, offering three options: Sport, Manual, and Comfort. Sport mode stands out as the best choice (for reasons we’ll explore shortly), delivering a balanced experience that almost negates the need for paddle shifters by intuitively predicting the ideal gear. Traction and stability control are similarly simple, offering just two settings: on or off—there’s no middle ground.

Once you’ve spent a little time behind the wheel, the weight of the car becomes apparent. At 3,900 lbs, the CLK63 AMG Black Series carries about 500 lbs more than we’d like, but what it lacks in lightness, it makes up for in dynamic driving characteristics. The steering, though heavy at low speeds, becomes razor-sharp as you pick up the pace.

Turn-in is precise, arguably among the best in its class. Thanks to the 6.2L V8 delivering 80% of its torque at just 2,000 RPM and maintaining it across the rev range, the car surges forward with authority—sometimes too much. Even with a limited-slip differential, putting all that power down can be a challenge, and the rear tires occasionally struggle to keep up.

On city streets, the Black Series feels somewhat restrained, as though it’s waiting for a more demanding environment. Take it to a winding backroad, however, and it truly comes alive. The car feels perpetually on edge, but as you tackle corner after corner, it begins to inspire confidence.

Hard braking holds up beautifully without fading, allowing you to dive deeper into turns. However, push beyond the limits, and the Black Series reminds you it’s not for the faint of heart—this car will bite back if you’re not ready.

While the handling is undeniably good, it stops short of greatness—and that’s perfectly okay. Here’s why: Mercedes tuned the suspension to encourage controlled chaos, delivering significant oversteer. Keeping the CLK63 AMG Black Series planted through corners is a challenge, even with its wide 285-section rear tires, as the car can easily overpower them and let the rear end slide.

This isn’t a machine for setting lap records—it’s a car designed to keep you grinning ear to ear, even if you’re not the fastest on the track. After all, there’s no denying that drifting through corners looks just as thrilling as it feels.
