In addition to the perfectly showcased new aerodynamic components, the GSC CLS63 AMG was also given a special performance package. In the aftermath of laborious efforts, technicians were thus able to create a remarkable 750 Horse Power (proven on test platform) and a maximum torque of 1,150 Nm from the 5.5 liter engine displacement of the V8 Biturbo. In contrast to the serially produced version of the CLS63 AMG, this makes up after all, an additional performance power of 225 HP!!! To achieve this immense power boost, the technicians gave the V8 Biturbo an additional water cooler for the charge air intercooler in addition to a set of bigger turbo-chargers as well as an exhaust system, which runs backwards from the chargers. The GSC CLS63 AMG is able to achieve the classical sprint from 0 to 100 km/h in just 3.7 seconds thanks to this brute power and attains a maximum speed of almost 350 km/h. To convert the power into propulsion without any major loss of traction, another set of elegant 20-inch rims was provided in addition to a KW coilover with adjustable suspensions on the front axle. The GSC rims on the front axle thus rotate in 8.5x20 inches with a 255/30R20 Continental tire and on the rear, in 10x20 inches with 295/25R20.
