Mercedes Benz started production of the 2014 S-Classes this week at their plant in Sindelfingen, Germany. Were not so sure if Mercedes accidentally revealed the 2014 S63 or they really wanted to give us a glimpse. They usually don’t reveal the 63 models of the cars for a while after they debut the car, and they revealed the new S-Class not too long ago. A video was posted on youtube showing the production of the new S-Classes and he first one you see is an s63. Although they still didn’t announce specs, were guessing its going to pack a 5.5l V8 twin-turbo engine, and they will probably add the performance package too, giving the car some extra power. Check the video out for yourself below.
