Poland-based Auto Dynamics just unloaded its new tuning package for the Mercedes-AMG C63 S codenamed as “Charon”. On the outside, the Merc appears almost the same as its standard version but as the saying goes, “beauty is only skin-deep”, there’s more to the car than what the eye can see.

Beneath the hood of the base AMG C63 S lies a 4.0-liter twin-turbo V8 engine with 503 hp and 516 lb-ft of torque. However, thanks to the AD850+ performance package of the tuner, additional 340 hp and 200 lb-ft can be squeezed out from the car, which brings its total output to a whopping 843 hp and 716 lb-ft of torque.

The package includes an ECU tuning as well as a new set of TTE turbochargers, a sports catalyst, Supersprint downpipes, and cat-back exhaust system with adjustable valves from Remus Innovation. The power modifications are also complemented by Eventuri carbon-fiber intake with upgraded air intakes for better air circulation, Weistec ASV/BOV blow-off adapter, Wagner Tuning carbon air injectors, and Weistec sump for the AMG Speedshift transmission.

Meanwhile, the exterior of the Mercedes-AMG C63 S gets a mild makeover with the AD Black Star body kit of Auto Dynamics. The package includes a blacked-out Panamericana grille, door handles, and the tuner’s badges. Lastly, it is topped off with a set of 20-inch BBS wheels wrapped in Michelin Pilot 4S tires complete with lowering springs by Eibach and Fischer Stahlflex brake lines.
