The Mercedes-AMG CLE 646 Spezialanfertigung

The Mercedes-AMG CLE 646 Spezialanfertigung began with a simple question: how can a CLE be developed further towards maximum driving dynamics? On the initiative of a small team, the project first took shape as a prototype. The goal was not merely a list of individual performance enhancements, but a complete reimagining of the vehicle as an integrated performance system.

Based upon the current production coupé, a unique special build was created featuring increased power output, a purpose-tuned chassis, comprehensive lightweight construction and extensive body modifications. Compared with the production model, weight was reduced by around 170 kilograms, while the bodyshell itself underwent extensive modifications. The result is a vehicle rebuilt from the ground up to Affalterbach’s highest manufactory standards, laying the foundation for the model designation “Spezialanfertigung”.

To achieve the exceptional driving dynamics of the Mercedes-AMG CLE 646 Spezialanfertigung, the bodyshell structure has been engineered to withstand the highest loads. Additional reinforcements and an integrated roll-over bar significantly increase bodyshell rigidity. Precision, stability and driver feedback benefit directly, particularly during spirited driving. To fully harness the car’s enormous performance potential, the aerodynamics were also developed with driving dynamics as the primary objective. The front diffuser, wing louvers, underbody aerodynamics and rear wing combine to create a carefully integrated aerodynamic package.

The manually adjustable front diffuser features “Street” and “Race” modes. The latter makes use of the Venturi effect, noticeably increasing front-axle downforce. The result is exceptional straight-line stability and precise steering feedback, both in corners and at high speeds. Open louvers integrated into the widened front-wings improve wheelhouse ventilation and contribute to additional downforce. A particular innovation is the channel system positioned next to the headlights, directing airflow through the wheel arches and out through the louvers. Front flics mounted on the sides of the front apron further optimize airflow and brake cooling.

The distinctive and exceptionally sporty appearance of the Mercedes-AMG CLE 646 Spezialanfertigung is characterised by its wide-body design, which has been engineered with uncompromising focus on maximum driving dynamics and performance. Extensive modifications to the bodyshell increase structural rigidity, creating the foundation for the vehicle’s exceptional performance potential.

A key element of the concept is its significantly wider stance. To achieve this, the bodyshell has been reinforced and widened. The result is an additional 60 millimetres of vehicle width at both the front and rear axles. This enhances stability, increases cornering potential and enables the use of exceptionally wide wheels and tyres.

In addition, numerous standard components have been replaced by carbon fibre solutions specifically engineered for demanding use on road and track, further emphasising the vehicle’s highly dynamic appearance.

The interior of the Mercedes-AMG CLE 646 Spezialanfertigung follows the same unwavering focus on lightweight construction and driving dynamics. The rear seats have been removed, along with the acoustic insulation. In their place, lightweight carbon-fibre door panels and ultra-lightweight high-end racing bucket seats with pronounced lateral support are fitted as standard, along with a roll-over bar that increases torsional rigidity, further enhancing driving dynamics of the Mercedes-AMG CLE 646 Spezialanfertigung.

In pursuit of the most direct driving experience possible, infotainment and other features have also been reduced. The removal of various drive modes and assistance systems has also enabled the number of controls on the AMG Performance steering wheel to be reduced. The steering wheel itself remains unchanged, and thanks to its DINAMICA microfibre covering and motorsport-inspired flattened shape, continues to provide exceptional grip and control in every driving situation.
