German tuning firm GAD has released a new performance package for the Mercedes CLS 63 AMG to take it to the next level. Aftermarket parts include larger turbochargers, a custom manifold, optimized intercooler and a new fuel system. These go along with the optional AMG Performance Package that boasts 558 HP and 799 Nm of torque. After all these parts mentioned above are installed, customers will receive a CLS 63 AMG with 803 horsepower and 1149 Nm of torque.
These are impressive results from a relatively modest tuning program. GAD also stated that the top speed was drastically increased from the tune, however the figures weren’t mentioned. All we know is that this Mercedes CLS 63 AMG will be much faster than the 186 mph top speed of the factory model.
