Recent spy photos posted up on MotorAuthority show that Mercedes-Benz is giving its flagship vehicle, the venerable S-Class, the nip-and-tuck treatment. The updated car is apparently due out as a 2013 model sometime later this year with relatively minor changes. Updates include LED running lights, the introducing of a few new powerplants including a plug-in hybrid, and a bit of a stretch in overall length to name a few. The plug-in hybrid technology would be taken from the 2009 Vision S500 concept vehicle, which was first shown at the 2009 Frankfurt Motor Show.
