2013 Mercedes-Benz CLS63 AMG Stealth by German Special Customs

Article by Christian A., on April 2, 2013

The 2013 Mercedes-Benz CLS63 AMG "Stealth" by German Special Customs is not exactly inconspicuous as it comes in a luminary orange color. The finishing specialists of German Special Customs installed a front bumper bar with integrated LED daytime running lights that appears bolder and more powerful than its serial counterpart.

CLS63 AMG also gets a new engine hood and a luxurious hot air outlet. The visual dimension of the four-door coupé is emphasized with new fenders and new side skirts with shaft. Furthermore, the rear section appears obviously more aggressive than in the serial model due to a totally new bumper with integrated carbon-fiber diffuser and side air outlets.

The angular end-pipes of a four-pipe sports exhaust system built of high-grade steel were incorporated in the diffuser. This is how the power of the German Special Custom’s CLS63 AMG is audibly expressed. The tuner enabled the 5.5 liter Biturbo-V8 to deliver 750hp and a maximum torque of 1,150 Newton meters.

To generate the added performance of 225hp, GSC engineers gave the “eight pointer” as well as other models a set of bigger turbo charger, an extra water cooler for the charge air intercooler and a new exhaust system. The Stealth-CLS is capable of accelerating from zero to 100 km/h in only 3.7 seconds and sprinting further to 350 km/h. It could easily surpass the 300 km/h sonic barrier.

The braking system, steering, and suspension of the new CLS63 AMG accompany the high-tech drive system flawlessly. It comes with AMG RIDE CONTROL sports suspension, with air suspension struts on the rear axle and front suspension struts on the front axle.

This also includes the automatic level control which is significantly enhanced by an electronically damping system; it instinctively regulates the damping qualities depending on the driving situations and lessens the roll angle of the body. The result: lightning-fast modifications between peak driving comfortability and the best possible quickness. The driver can switch between the three suspension modes of “Sport plus”, “Sport”, and “Comfort” with the single press of a button.

The independently built front axle, with a 24 mm wider track width, is the ideal counterpart for the freshly enhanced electromechanical AMG sports parameter steering. Not only does it highlight variable power assistance that is modified according to the suspension mode, it also helps reduce fuel consumption due to the steering assistance system getting power only when the car is actually being steered.

The 3-stage ESP has personalized setting choices that provide a clear edge when it comes to integrating maximum driving satisfaction with optimum driving protection.

AMG ceramic high-performance composite braking system is available as an option

A flawless deceleration when driving exceptionally fast is guaranteed by the AMG high-performance braking system with 360 mm, with internally ventilated and perforated brake discs all-round. Remarkably resistant, motorsports-tested composite technology is utilized on the front axle.
