Mercedes-Benz’s flagship sedan, the S-Class, is due for a midlife makeover this year. Earlier, the carmaker had shared images of the prototype covered in camouflage, but an official teaser could be revealed soon.
This leaked image could be one of the first teasers of the S-Class facelift. It shows its front silhouette, highlighting the redesigned grille and new headlamp units.

It appears that the new S-Class will feature a hexagonal grille with four horizontal slats and a central spine. Also note that it has an illuminated frame. The headlights have star-shaped DRLs with an eyebrow.
The S-Class facelift will come with an updated range of engines. The S450 will be powered by an inline 6-cylinder unit producing 443 lb-ft of torque, peaking at 472 lb-ft with the overboost function. The S500 will reportedly have 442 hp, while the S580 will get a flat-plane V8 with 530 hp and 553 lb-ft. A plug-in hybrid version will be on offer.
