Mercedes CLS 63 AMG: Complete Review And Performance Specs

The Mercedes CLS 63 AMG stands out as a unique blend of grand touring luxury and high-performance engineering. This four-door coupe redefines the sports sedan category with its sleek silhouette and formidable powertrain, offering drivers an exhilarating experience without sacrificing comfort. Powered by a twin-turbocharged V8, it delivers supercar-like acceleration in a practical package suitable for daily drives or long highway journeys.

Design and Exterior Highlights

The CLS 63 AMG’s exterior captures attention with its flowing lines and aggressive stance. The elongated hood, fastback roofline, and wide fenders create a visual drama that hints at the performance beneath. Large alloy wheels filled with massive brakes and subtle aero enhancements like spoilers and side skirts emphasize its sporty intent. This design not only turns heads but also improves aerodynamics for high-speed stability.

• Sweeping coupe-like profile with four practical doors
• Prominent AMG grille and LED headlights
• Quad exhaust tips accentuating the rear diffuser

Available in various premium paint finishes, the bodywork balances elegance with intimidation, making it a standout in any parking lot or on open roads.

Engine and Performance Capabilities

At the heart of the CLS 63 AMG lies a 5.5-liter twin-turbo V8 engine, producing up to 577 horsepower and 590 lb-ft of torque in its S 4Matic variant. This powerhouse propels the car from 0-60 mph in as little as 3.6 seconds, with quarter-mile times around 12 seconds at over 119 mph. The naturally aspirated versions from earlier models, like the 6.2-liter unit making 507 hp, offered a raw, high-revving character, but the turbo setup provides broader torque delivery for effortless overtaking.

Paired with a seven-speed dual-clutch automatic transmission, power reaches all wheels via standard 4Matic all-wheel drive, ensuring traction in varied conditions. Drive modes range from Comfort to Sport+, allowing customization of throttle response, shift points, and suspension firmness. Even in relaxed settings, the engine’s low-end grunt makes it forgiving for urban commuting.

These figures position the CLS 63 AMG as a benchmark for luxury performance, outpacing many dedicated sports cars while accommodating passengers.

Interior Comfort and Technology

Step inside, and the cabin exudes Mercedes-Benz luxury with high-quality leather, wood accents, and metallic trims. The front seats feature dynamic bolsters that adjust for cornering support, enhancing driver confidence without rigid side wings. Rear space is generous for a coupe-style roofline, with the center console extending rearward to house climate controls and storage, creating a unique four-seater layout.

The COMAND infotainment system, though dated in graphics by modern standards, includes navigation, a premium audio setup with multiple speakers, and Bluetooth connectivity. Four-zone climate control, ambient lighting, and power-adjustable seats with heating and ventilation ensure long-trip comfort. Safety tech abounds: adaptive cruise control, lane departure warnings, blind-spot monitoring, and a suite of airbags.

• Dynamic seat bolstering for sporty drives
• Large touchscreen for media and nav
• Abundant storage and cupholders

Driving Dynamics and Handling

Mercedes’ AIRMATIC adaptive suspension shines, offering three levels of damping from plush Comfort to taut Sport+. In everyday scenarios, it absorbs bumps smoothly, making the car feel lighter than its size suggests. The all-wheel-drive system excels in wet weather, maintaining composure without understeer tendencies.

Steering is precise yet light, with quick ratio for agile responses. Brakes, with massive multi-piston calipers, provide strong stopping power, though they require adaptation in traffic due to sensitivity. The dual-clutch transmission shifts rapidly in performance modes but can hesitate at low speeds, a common trait in early implementations.

On twisty roads, the CLS 63 AMG transforms into a corner-carver, with minimal body roll and explosive exits thanks to torque vectoring. Highway cruising is serene, with noise insulation keeping the turbo V8’s thrum subdued until provoked.

Fuel Efficiency and Practicality

Despite its performance, the CLS 63 AMG posts EPA ratings of 16 mpg city and 22 mpg highway, though real-world figures often dip lower in spirited driving. A stop-start system aids efficiency at idle, and premium fuel is required. Trunk space accommodates luggage for weekend getaways, and the sedan layout facilitates family use.

Maintenance costs reflect its complexity, with turbo and high-performance components demanding specialized service. Reliability is solid for an AMG, but regular upkeep is key for longevity.

Competitors and Market Position

The CLS 63 AMG competes with the BMW M6 Gran Coupe, Audi RS7, and Porsche Panamera Turbo. It offers superior luxury and straight-line speed but trades some handling purity for comfort. Priced from around $100,000 new (historical), it appeals to buyers seeking exclusivity over outright track prowess.

Pros and Cons

• Pros: Blistering acceleration, luxurious interior, versatile drive modes, all-weather grip
• Cons: Thirsty fuel consumption, transmission lag at low speeds, high ownership costs
