Key Points
1
The CLE 646 is the second model in Mercedes-Benz’s Mythos series, following the AMG PureSpeed, and Mercedes-AMG says all 30 cars had been spoken for before its public debut.
2
Its V8 uses a flat-plane crankshaft to reduce rotating mass and sharpen throttle response; peak torque of 850 Nm is available from 2,500 to 4,500 rpm.
3
For sustained high-load driving, AMG fitted three separate cooling circuits, including dedicated low-temperature circuits for the charge air, transmission oil and 48-volt electrical components.
4
The coupe has a body widened by 60 mm at both the front and rear, along with newly developed coil-over suspension and extensively engineered aerodynamic components, including an adjustable carbon-fiber rear wing.
5
Mercedes-AMG management board chairman Stefan Weckbach described the project as one in which “a group of very rational engineers dreamt of a very irrational car,” saying the result delivered “maximum driving dynamics and an unparalleled driving experience.”
Mercedes-AMG has unveiled the CLE 646 Spezialanfertigung, an ultra-rare performance coupe that pushes the limits of road-legal engineering. The car pairs a 646-horsepower twin-turbo V8 with lightweight carbon-fiber bodywork and track-focused suspension, achieving a 0-to-62-mph time of 3.9 seconds. Only 30 examples will be built, and Mercedes-AMG says the entire allocation has already been claimed before the car's public debut.
A 646-HP V8 Built for Maximum Performance
The heart of the CLE 646 is a 4.0-liter twin-turbo V8 that delivers 646 PS (646 horsepower) and 850 Nm (627 lb-ft) of torque. Mercedes-AMG engineered the engine with a flat-plane crankshaft to cut rotating mass and sharpen throttle response. Peak torque is available from 2,500 to 4,500 rpm, and power flows exclusively to the rear wheels through a nine-speed transmission. The car claims a top speed around 193 mph.
Carbon Fiber and Cooling Systems for Track Duty
Weight reduction is central to the CLE 646's design. The coupe features extensive carbon-fiber bodywork, polycarbonate windows, and a titanium Akrapovič exhaust system. Mercedes-AMG stripped out the rear seats to cut mass further and fitted three separate cooling circuits to handle sustained high-load driving. These circuits cool the charge air, transmission oil, and the 48-volt electrical components independently, ensuring reliability during extreme use.
Aggressive Aerodynamics and Suspension Redesign
The body has been widened by 60 mm at both front and rear to accommodate wider tires and improve stability. Mercedes-AMG developed an entirely new coil-over suspension system and engineered extensive aerodynamic components, including an adjustable carbon-fiber rear wing. Racing equipment throughout the chassis emphasizes handling sharpness and driver feedback over comfort.
Part of Mercedes' Exclusive Mythos Series
The CLE 646 is the second model in Mercedes-Benz's Mythos Series, following the AMG PureSpeed. Mercedes-AMG management board chairman Stefan Weckbach said the project brought together "a group of very rational engineers" who "dreamt of a very irrational car," delivering "maximum driving dynamics and an unparalleled driving experience." Pricing remains undisclosed, but the car is expected to cost substantially more than the standard CLE 53.
