The Mercedes-Benz C 63 AMG's normally aspirated M156 V8 is one of the greatest old-school V8 engines you can still buy. Its crossplane muscle car rumble that transforms into an all-out lion roar at higher rpm can only be topped by a tuned version of the engine.
The specialists from HMS Tuning have one of the most comprehensive tuning solutions for the AMG
-developed engine, and one of the most powerful C 63 AMGs you can currently buy in Europe comes from their skunkworks team in southwest Germany.
With the help of a screw-type supercharger and a host of other goodies, the M156 V8 under the hood has been massaged to offer up to 690 hp and 876 Nm (646 lb ft) of torque.
To further enhance the car's notoriety they've recently released a video of their most powerful tuning package for the C 63, specifically created to drop jaws after the play button has been clicked. From our point of view they have more than succeeded. Enjoy the following video and the image gallery below, we know we did.
