Mercedes-Benz is readying the C-Class for an update, and these photos show – for the first time – a prototype of the C 63 AMG. The spy pictures reveal a new look for the successful C-Class which has been on the market since 2007. Changes include new headlights, a new front bumper and a new bonnet. The rear is expected to feature a new set of lights and some modifications to the bumper.Some engine upgrades will be on offer while the interior should receive minor changes, too. Installed technologies include the Agility control pack, the Comand system with Linguatronic voice control and the Neck Pro safety system.Mercedes-Benz did away with the CLK, replacing it with the E-Class Coupe. The same will happen when the CL changes to the S-Class Coupe. It follows that the C-Class could also get its own Coupe model to sit above the CLC. The updated C-Class will go on sale in global markets in 2011, just months before the all-new BMW 3 Series and the Audi A4 facelift.
