Mercedes S-Class leaked ahead of official reveal event later today. Mercedes debuts its brand new S-Class in a few hours time, but wouldn’t you know it, a picture of the luxury sedan appears to have already leaked online. A single image, which looks like a smartphone photo taken at a media event, was posted to several social media accounts, including on CarsinPixels/X, showing a silver 2027 S-Class from a front-three-quarter angle. Clearly visible are the star-design DRLs and a grille featuring a black frame, just like the one on its E-Class little brother. The MY27 S-Class will reportedly get a new flat-plane crank V8 and will also feature new autonomous driving tech.
