This Mercedes S-Class was spied recently with very little changes on the outside. However, the interior is where the S-Class shines, so it will be getting all the gadgets that were just released with the all-new Mercedes-Benz E-Class. This will probably make it the most technologically advanced production vehicle for sale today. The new S-Class will likely get new powertrains. The S450 will probably get a new 6-cylinder engine. It is not yet known when the S-Class will be revealed at auto shows.
