The High-Performance Version of the CLS-Class The Mercedes-Benz CLS63 AMG was the top-performance variant of the CLS-Class, offering a blend of luxury, coupe-like styling, and extreme power.
Twin-Turbo V8 Power The CLS63 AMG features a 5.5-liter twin-turbocharged V8 engine, producing up to 577 horsepower (585 PS) and 800 Nm (590 lb-ft) of torque in the S-Model.
0-60 MPH in Just 3.5 Seconds Thanks to its AMG-tuned 4MATIC all-wheel-drive system, the CLS63 AMG S-Model could accelerate from 0 to 60 mph (0-97 km/h) in just 3.5 seconds, making it one of the fastest four-door coupes of its time.
Hand-Built AMG Engine Each CLS63 AMG’s engine was hand-assembled by a single technician at AMG’s Affalterbach facility, following the "One Man, One Engine" philosophy.
A Unique Four-Door Coupe Design The CLS-Class, including the CLS63 AMG, is credited with popularizing the four-door coupe trend, influencing later models like the Audi RS7 and BMW M8 Gran Coupe.
Available in Rear-Wheel Drive and 4MATIC AWD Early versions of the CLS63 were rear-wheel drive, but Mercedes later offered an AMG Performance 4MATIC all-wheel-drive system, providing better traction and acceleration.
Advanced AMG SPEEDSHIFT MCT Transmission The 7-speed AMG SPEEDSHIFT MCT transmission replaced the traditional torque converter with a wet-clutch system, offering quicker shifts and a more responsive driving experience.
Aggressive AMG Styling Upgrades The CLS63 AMG features a more aggressive front bumper, larger air intakes, quad exhaust tips, and flared wheel arches, making it stand out from the standard CLS models.
High-End Luxury Interior with AMG Touches Inside, the CLS63 AMG includes AMG sport seats, carbon fiber or wood trim, a flat-bottom steering wheel, and premium leather upholstery, combining performance with comfort.
A Future Collector’s Car As Mercedes-AMG has shifted to hybrid and downsized engines, the CLS63 AMG with its powerful V8 is becoming a sought-after modern classic, especially in RWD configurations.

The C218 CLS63 is a wolf in sheep’s clothing—a 5.5L twin-turbo V8 (525–585hp) with 4MATIC+ grip, sleek four-door coupe styling, and hand-stitched Nappa leather. A modern classic that’s depreciated into "performance bargain" territory.
