When it comes to muscle cars the Yanks rule supreme, until you sample anything with a gleaming AMG badge on it.

Overpowered rear wheels are the staple of the boys from Affalterbach, and the lightweight, relatively compact C 63 AMG is one of the best examples of that mantra.

German tuner KTW, however, thinks what comes out of the AMG box is merely an appetiser, and has taken the Mercedes-Benz C 63 AMG’s V8 engine, tuning the 6.2-litre to develop 525bhp as opposed to the stock 451bhp figure.
