Merc's new flagship takes many of its new design cues from the F700 concept that debuted back in 2007, specifically the larger, more upright grille and the redesigned headlamps that now incorporate LED running lights (just like what we've seen on the new SL and GL models). The big sedan's overall shape doesn't change too much from the car that's currently on sale, though things seem to be a little swoopier for this new generation.
Under the hood, we can expect Mercedes' latest engines to be on tap, including the 4.6-liter twin-turbocharged V8 as well as some V6 options. Naturally, an AMG model will follow suit, likely using the new 5.5-liter twin-turbo V8 in the S63 AMG.
Look for the redesigned S-Class to officially bow later this year.
