We've been seeing camouflaged test mules of an updated Mercedes-Benz CLS-Class sedans driving around for some time now, but the German automaker apparently can't keep it under wraps anymore. On Saturday the online motoring press worldwide lit up with two pictures of the facelifted "four-door coupe", reportedly leaked by someone inside Mercedes ahead of its intended debut.
The pictures show an updated top-of-the-line CLS 63 AMG. What we can tell from the images is that the newest AMG rocket gets a new grille split in three sections instead of four; upgraded wheels from 18 to 19 inches, with a style similar to those on the Porsche 911 Turbo; led tail-lights; a carbon fiber rear spoiler; a new rear diffuser; and updated exhaust outlets.
Whether any mechanical changes have been made has yet to be revealed, but we'll be sure to keep you posted. A shot of the rear is included after the jump.
