The Mercedes-AMG C63 S sedan has been handed a hefty power increase and some mild visual enhancements by the folks over at Auto-Dynamics.

Dubbed the "Charon", this package provides peak outputs of 629 kW and 972 N.m of torque from Affalterbach's twin-turbo 4,0-litre V8, which delivers 375 kW and 700 N.m in standard form. How did the Polish tuner reach these lofty figures? Well, it added a pair of TTE turbochargers, a sports catalyst, Supersprint downpipes and a cat-back exhaust system from Remus Innovation, while also obviously doing some ECU tuning.

For improved air flow, an Eventuri carbon-fibre intake has been fitted, along with upgraded air filters. This is joined by an ASV/BOV blow-off adapter from Weistec. In order to cope with the extra power, Auto-Dynamics has added a Weistec sump to the AMG Speedshift transmission, carbon air injectors from Wagner Tuning and yet more upgraded filters.

The Charon package also includes a set of Eibach sports springs and 20-inch BBS CL-R alloy wheels finished in satin black and wrapped in Michelin Pilot Sport 4S tyres.

The super sedan visual presence has been amplified by means of an “AD Black Star” package, which provides a black finish for the grille, door handle covers, badges, boot accent strip and engine trim.
