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.
The 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.
