Mercedes' new coupé is the most dynamic incarnation of the C class. The sporty spearhead is the AMG version. The C 63 AMG coupé is powered by a 4-liter, 8-cylinder twin-turbocharged gasoline engine with 350 kW.But even that can be increased: the AMG S version boasts an additional 25 kW. Equipped with a maximum of 375 kW and 700 Newton meters of torque, we took the C 63 S AMG onto a racetrack to let it strut its stuff.
