The facelifted W222 Mercedes-Benz S-Class is set to be unveiled very soon, but photos of the undisguised new car have already surfaced on news portal SaudiShift.com, giving us a good look at the changes inbound for Stuttgart’s benchmark luxury sedan.

Changes to the exterior of the car include revised headlights, now featuring triple LED daytime running lights and the 84-diode Multibeam LED technology found on the W213 E-Class. There’s also a dual-bar grille on this V8-powered example, meaning that it will no longer be restricted to V12 and Maybach models.

Lower down, the bumper design has also been updated, with a full-width air intake as seen on the E-Class – albeit with a horizontal chrome trim piece that bisects it. At the back, the LED tail lights look to get the E-Class-style “stardust effect,” while the rear valence has been redesigned with integrated tailpipes.

The interior will also gain a few changes, such as a glass cover for the Widescreen Cockpit (twin 12.3-inch displays for the instruments and infotainment system) to provide a flat-panel look, as well as a new three-spoke steering wheel with touchpads to control the two screens. Both were first introduced on the E-Class.

Seen here is what appears to be a US-spec model carrying the S 560 badge, which should replace the S 550 sold in America; other markets will likely stick to the S 500 moniker, as is the case currently. Power comes from a new 4.0 litre twin-turbo V8 – essentially a detuned series-production version of the AMG mill that powers the C 63 and AMG GT.

The engine is shared with the G 500 4×4², but SaudiShift claims that the one in the S-Class will be uprated to produce 54 hp more at 476 hp, all while using 12% less fuel than the 455 hp 4.7 litre biturbo V8 found under the bonnet of the current S 500/S 550.

Other new engines should also be on the cards, led by the new 3.0 litre M256 inline-six, which features a 48V electrical system. Fresh turbodiesel engines are also set to feature, in the form of the 2.0 litre four- and 3.0 litre six-cylinder oil burners from the W213 E-Class.

The use of the new mills has become possible with the adoption of the E-Class’ electronic architecture, which will also enable the new S-Class to receive a host of driver assist and autonomous system technologies that have been deployed on the E-Class.

The list includes Remote Parking Pilot as well as Active Brake Assist, which is capable of scanning other lanes for cars and initiating braking earlier if it senses an evasive manoeuvre is impossible. Other features are Active Distance Assist Distronic with Active Speed Limit Assist, Evasive Steering Assist, Active Lane Keeping Assist and semi-autonomous Active Lane Change Assist, part of the Drive Pilot package.
