Mercedes-AMG CLE 646 Spezialanfertigung Debuts as 646-HP Limited Edition V8 Coupe
The Mercedes-AMG CLE 646 Spezialanfertigung has debuted as an ultra-limited track-focused coupe developed through the Mythos program, featuring a 637-horsepower twin-turbo V8 engine and a rear-wheel-drive layout according to Motor1.com France. Production is strictly capped at 30 units, and the article confirms that every single vehicle has already been sold.
Engine Performance and Powertrain Specifications
Underneath the hood, the standard six-cylinder engine found in the CLE 53 has been replaced by a 4.0-liter twin-turbocharged V8. The powerplant generates 646 horsepower and 850 Nm of torque, directing all power exclusively to the rear wheels via a torque-converter automatic transmission.
AutoScout24 notes that the mechanical layout serves to reassure purists seeking traditional V8 performance. Motor1.com France lists the output at 637 horsepower, while the article records the figure at 646 horsepower. The vehicle sheds 170 kilograms compared to the CLE 53, bringing its empty weight to 1,895 kilograms according to the article. Fitted with semi-slick tires, the coupe accelerates from 0 to 100 km/h in 3.9 seconds, reaches 200 km/h in 11.4 seconds, and achieves a top speed of 310 km/h.
Chassis Engineering and Aerodynamic Bodywork
The exterior styling draws direct inspiration from past Black Series models and Porsche’s GT3 RS, according to the article. The body has been widened by 60 millimeters and makes extensive use of carbon fiber, particularly on the hood and components of the front bumper. The aerodynamic package features a prominent front splitter and a fixed rear wing, both equipped with manually adjustable elements.
Chassis modifications include fully adjustable coilover suspension developed in collaboration with KW, a specialized exhaust system engineered by Akrapovic, and upgraded brake cooling systems designed to withstand intensive circuit use. While sharing functional similarities with historical Black Series machines, Mercedes-AMG has officially integrated the vehicle into its exclusive Mythos initiative rather than applying the Black Series designation.
