In the recent past, we’ve seen CLS63 AMG by Kicherer, Vorsteiner, SR Auto Group, Vitt, Mansory and Wald to name a few.
The latest tuner to jump on the CLS63 AMG bandwagon is GAD with their 803hp monster.
GAD started out with a standard CLS63 AMG, which already has 557 hp and 800 Nm of torque , enough for most driver’s with dreams of speed. They then treated the CLS to new turbochargers that our from GAD, enhanced the cooling system, optimized manifolds, installed a full sport exhaust system with downpipe, race catalysts and valved mufflers. And, to top it all off, GAD modified the software for new boost pressure and ignition timing data.
All of this work resulted in the AMG’s M157 V8 outputting a whopping 803 hp and 1,150 Nm of torque. Meaning, the CLS63 can go past 186 mph, without a speed limiter.
On the exterior, the GAD CLS63 features gunmetal wheels, from HRE, grille and side mirrors.
