GAD Motors has recently released an upgrade program for the Mercedes-Benz CLS 63 AMG.
According to the German tuner, the 5.5-liter twin-turbo V8 engine has been tuned to produce 803 hp at 5,529 rpm and 1,149 Nm of torque at 4,114 rpm instead of the standard 558 hp and 800 Nm of torque. This allows the four-door coupe to hit a top speed of more than 300 km/h.
In order to provide the extra output, GAD Motors installed a new sports air filter, an optimized intercooler, enhanced water cooler pump, larger GAD turbochargers (30 percent bigger) and a custom sports exhaust manifold with sports catalyst. In addition, the fuel and ignition systems also had to be upgraded.
