This is an 843bhp Mercedes-AMG C63 S

For most of us, the 503bhp and 516lb ft of torque that AMG extracts from the C63 S is probably sufficient. Answering a question few asked, then, is Polish tuner auto-Dynamics.pl.

Welcome to the company's ‘Charon’ – lovely bit of Greek mythology for you there. Essentially, this thing is a C63 S with 843bhp and 717lb ft of torque.

The tuner has swapped out the standard twin AMG turbos, flashed the 4.0-litre V8’s ECU and fitted an Eventuri carbon fibre air intake to reach that power figure. 

There’s also a valve-controlled cat-back sports exhaust system – consider the standard car was hardly quiet in the first place. This thing will be LOUD.

There are plenty of exterior bits too, with all of the shiny AMG chrome being swapped out for matte black details. Check out those BBS wheels too. Lovely stuff.

Does an 843bhp C63 appeal? Or is there such a thing as too much power?
