The package is available for the saloon and estate models, boosting peak output by 22kW to 358kW, approaching the level of performance offered by C-Class DTM vehicles at 377kW.
It also includes an AMG high-performance braking system featuring composite technology on the front axle, a carbon fibre spoiler lip and an AMG performance steering wheel in nappa leather and Alcantara.
As a result, C 63 AMG's equipped with Performance Package Plus accelerate from zero to 100km/h in 4.4 seconds and on to 200km/h in 13.9 seconds - 1.2 seconds quicker than the standard model.
This increase in power has been achieved by adopting the forged pistons from the new SLS AMG gullwing together with new connecting rods and a lightweight crankshaft translate into a weight saving of three kilograms.
The reduced inertia boosts responsiveness of the uprated AMG 6.3-litre V8 engine, which is recognisable from the variable intake manifold painted in titanium grey.
The brake discs feature a composite design and incorporate red painted brake callipers all round showing the AMG logo.
The Performance Package Plus for the C 63 AMG will be available to order in Europe from December, with Australian availability yet to be confirmed.
