An official performance kit called Performance Package Plus is being offered for the Mercedes-Benz C 63 AMG range. It gives a power increase and some cool interior upgrade options.

Mercedes-Benz is offering C 63 AMG customers a new factory-fitted enhancement kit for their cars called the Performance Package Plus. Both the sedan and the wagon can be fitted with the package.

The 6.3-litre (6208cc) V8 engine has been modified by fitting forged pistons adopted from the new SLS AMG, a lightweight crankshaft, new connecting rods and a new engine management system.

Power goes from 336kW (457hp) to an E 55 AMG-rivalling 358kW (487hp). Peak torque is 600Nm (443 lb-ft) at 5,000rpm. Cars like the new updated Porsche 911 Turbo and the Nissan GT-R, as well as the C-Class DTM also play in that power league. It will go from 0 - 100km/h in 4.4 seconds (4.5 seconds for the wagon), 0 - 200km/h in 13.9 seconds and top off at an electronically limited 250km/h.

Kit includes an AMG carbon fibre lip spoiler on the boot lid (for the sedan), a new AMG high-performance braking system and an AMG performance steering wheel in nappa leather. The wheel's grip area is covered in strong but soft Alcantara. Black designo leather can be ticked off the options box for €2,856. It covers the upper section of the dashboard, the upper door trim and the armrest on the centre console.

Prices for the Performance Package Plus are €7,080.50 and €6,426.
