We have lost count of the upcoming cars that have been spied testing for cold weather conditions and the latest addition is the Mercedes S Class AMG Coupe. A few of you may recognize it as the CL-Class but this is an S Class AMG Coupe which belongs to the third generation of W216 models. Set for a debut in Geneva next month, the Coupe was spotted with daytime running LED headlights, an all new bumper restyled taillights and a sturdier looking grille. Minor tweaks will be seen on the inside where the styling will be a tad different and the Coupe will pack in more technology. The Coupe which will break cover in a number of years will stay true to its engines that power the 2010 S Class facelifted model. The spied model features a Twin-Turbo V12 engine that can churn an astounding 604hp but we will to wait for long to see that engine power the factory finished model. [via WCF]
