Performance Package Plus for the Mercedes C 63 AMG

Mercedes-Benz has announced a new performance package for the high-performance C 63 AMG. Called the Performance Package Plus, it is available for both the sedan and wagon variants. The most crucial update thanks to the package is the bump in horsepower. The standard C 63 AMG outputs 457hp from its 6.3 litre V8 however with the package power is increased to 487hp.

The reason behind the 30hp jump is the use of forged pistons from the new SLS AMG’s powerplant. Mercedes also fitted new connecting rods and a lightweight crankshaft. These help reduce weight by about three kilograms. There is also a new engine management system.

The package also includes a new AMG high-performance braking system. The brake discs feature a composite design and are connected to an aluminium bowl to avoid temperature peaks. The connection between the disc and bowl is new. Instead of the usual screw connection, the aluminium bowl is now connected to the brake disc via cast-in arms. The auto maker claims that this can help provide a more homogenous temperature distribution on the brake disc.

An AMG carbon fibre spoiler lip on the boot lid (for the sedan) and an AMG performance steering wheel finished in nappa leather with its grip area trimmed in Alcantara make up the rest of the upgrades. Thanks to the revisions made to the engine, the C 63 can sprint from naught to 100 km/h in 4.4 seconds (4.5 seconds for the estate) which means the acceleration time is reduced by 1.2 seconds.

It will continue till the speedometer tops out at 250 km/h (electronically governed). The Performance Package Plus costs €7080.50 for the sedan or €6426 for the estate. The package will be launched in December 2009. An additional €2856 will get you a new black designo leather that covers the upper section of the dashboard, the upper door trim and the armrest on the centre console.
