Mercedes-AMG CLE 646 Spezialanfertigung: A V8 Return to Form
The automotive world recently witnessed a seismic shift, not of electric proportions, but of internal combustion triumph. Mercedes-Benz AMG, the legendary purveyor of performance, has answered the fervent cries of enthusiasts worldwide, reintroducing the revered twin-turbo V8 engine into the CLE coupe. This is a victory for pure engineering, a testament to AMG’s commitment to sonic excellence, and a definitive statement against the era of four-cylinder plug-in hybrid dominance.
We are proud to introduce the Mercedes-AMG CLE 646 Spezialanfertigung, a street-legal masterpiece that debuted with understated grandeur. What sets this extraordinary machine apart is the marriage of exquisite design with raw power, all wrapped in a limited-edition package that is already sold out, leaving enthusiasts clamoring for a chance to own this piece of automotive history.
The Powerhouse Within: Unveiling the V8 Engine
At the heart of the CLE 646 Spezialanfertigung lies a 4.0-liter twin-turbo V8 engine, generating a staggering 637 horsepower and 627 lb-ft of torque. This isn’t just any V8; it features a flat-plane crank designed to reduce rotating mass and enhance revving characteristics. This translates to exceptional throttle response that will delight driving enthusiasts and provide a thrilling, visceral connection to the road.
Complementing this beastly engine is a custom Akrapovič exhaust system, which unleashes a symphony of growls, pops, and roars that have long defined the AMG experience. The absence of the controversial plug-in hybrid system means the 646 utilizes a more traditional 48-volt setup, ensuring a pure, unadulterated driving experience.
To keep this power in check, the CLE 646 Spezialanfertigung employs a high-temperature cooling circuit dedicated to engine cooling, along with two low-temperature circuits managing air and transmission oil cooling, as well as the 48-volt components. This advanced thermal management system ensures peak performance under all driving conditions, providing peace of mind and optimal efficiency.
Transmission and Performance
While the idea of a manual transmission might be tempting for purists, the CLE 646 Spezialanfertigung features a 9-speed automatic transmission. This sophisticated torque-converter setup is capable of executing multiple downshifts in rapid succession, providing a smooth and responsive driving experience.
AMG has implemented a revised launch control program that allows the 646 to sprint from 0 to 62 mph in just 3.9 seconds, 0 to 124 mph in 11.4 seconds, and reach a top speed of 193 mph. This performance profile makes the CLE 646 Spezialanfertigung a true contender in the hyper-performance segment, offering exhilarating acceleration and top-tier handling.
Aerodynamics and Design
The exterior of the CLE 646 Spezialanfertigung is a masterclass in automotive design. The wide-body treatment adds 2.4 inches of width at both the front and rear of the coupe, giving it a muscular and aggressive stance. The front fenders are crafted from carbon fiber and feature integrated air outlets designed to maximize cooling efficiency for the powertrain.
The hood features a central cold air intake that is both functional and aesthetically pleasing, drawing cool air into the engine bay to maintain optimal performance. The trunk lid has been reinforced and sports a massive, adjustable carbon fiber wing mounted on trapezoidal supports, ensuring maximum downforce and stability at high speeds.
Lightweight Construction and Interior Excellence
In the pursuit of performance, Mercedes-AMG has implemented aggressive lightweighting strategies, shedding 375 pounds from the CLE 646 Spezialanfertigung. This includes the removal of numerous comfort and assistance systems, such as the Parktronic parking assistant. The carbon fiber body panels and polycarbonate side and rear windows further reduce weight, while even the 12-volt starter battery is lighter than standard.
The sound system has been simplified to save weight, the rear seats and acoustic insulation have been removed, and the deletion of drive modes and assistance systems has streamlined the dashboard. Lightweight racing bucket seats and carbon fiber door cards have been swapped in, along with a roll bar for enhanced support and rigidity. An optional six-point harness for both driver and passenger is available in the Performance Package. All in, the CLE 646 Spezialanfertigung weighs 4,178 pounds, proving that true performance comes from shedding excess weight.
The Mythos Series: A Handful of Perfection
This latest model is part of the exclusive Mythos Series, with only 30 units being produced worldwide. This limited production run ensures that owners of the CLE 646 Spezialanfertigung will possess a rare and exclusive piece of automotive engineering. While the car is already sold out, the dedication of enthusiasts ensures that such exclusive creations will continue to grace the roads in the future.
Mercedes-AMG’s decision to reintroduce the V8 engine into the CLE coupe is a testament to their commitment to performance and their understanding of what true driving enthusiasts desire. The CLE 646 Spezialanfertigung is more than just a car; it’s an experience, a statement, and a piece of history that will be cherished by those lucky enough to own one. As the automotive world continues to evolve, one thing remains certain: the spirit of performance lives on at Mercedes-AMG.
