Images and details of Affalterbach’s facelifted C63 AMG have been released, little more than a month before its Geneva auto show debut. Mercedes-Benz’s entry-level V8 sports sedan has been around since 2007 and, to ensure it remains in touch with contemporary design trends, a series of subtle styling changes have been visited upon the C63.More elegant?A set of SL-inspired headlights are the most pronounced styling upgrade, with a strip of LEDs now underscoring the revised lower front fascia and bumper. There is a reshaped bonnet surface too, fronted by a new grille with neat chrome accenting. LEDs are added to the C63's taillights, whilst the rear diffuser has been slightly reshaped to improve its airflow management properties. The C63’s side profile is enhanced by redesigned multi-spoke 18-inch alloy wheels.Beyond its newfangled looks, C63’s facelift adds some interesting mechanical configuration upgrades too.Quicker shifting seven-speederAMG’s renowned M156 6.2-litre V8 has been retained and should continued to power the C63 until 2012, despite most of AMG’s range being in the process of converting to the new M157 5.5-litre bi-turbo engine. The C63’s naturally-aspirated V8 remains unchanged in terms of power delivery (still good for 336kW), yet AMG will offer an optional Development Package (forged pistons, lightweight conrods, new crankshaft), raising peak power to 353kW. This AMG Development Package is a new name for the company’s Performance Package Plus, available since 2009, and in addition to the surge in power it also adds red brake calipers, a new multifunction AMG steering wheel and composite boot spoiler…Most significantly, the facelifted C63 AMG will shift ratios courtesy of AMG’s seven-speed Speedshift MCT transmission, which is quite an upgrade over its conventional torque converter automatic. AMG says the new transmission features a high-performance clutch pack to deliver the quickest, smoothest shift regime when channelling the 6.2-litre V8’s awesome power to the rear-wheels – where an optional limited-slip differential aids traction security.Another boon of the MCT tranmission is the presence of launch control, for those C63 owners who fancy the occasional bout of quarter-mile racing action.Available in sedan and estate configuration, the C63 AMG’s upgrades should see it through until the end of 2012, when it is bound to lose its naturally-aspirated V8 in favour the 5.5-litre bi-turbo.
