Mercedes-Benz has revealed the S-class Coupe and Cabriolet facelifts just before they will make their public debut at the Frankfurt motor show.
The premium two-door models follow the S-class sedan’s design tweaks and come with new OLED tail-lights, each having 66 individual OLEDs. The exterior styling changes include slightly changed bumpers with chrome trimmings, new sills and chrome-plated tailpipes similar to the previous S65 Coupé and Cabriolet. The AMG-spec performance models get the AMG grille and larger air ducts in the front bumper.
The interiors also get a refresh and an updated infotainment system. There are three new trim lines on the inside as well as a choice of three new upholstery lines. The S-Class Coupé and Cabriolet’s 12.3-inch digital instrument cluster comes with revised graphics and the choice of three new themes: Classic, Sport and Progressive. Mercedes’ Comand infotainment system now gets updated software, allowing it to support 3D topographical map displays and Car-to-X messages.
The top-spec variants of the coupe and cabriolet will also be offered with revised driver assistance systems like the Active Distance Control Distronic cruise control and Active Steering Assist functions that have been introduced on the S-Class sedan.
The entry-level S-class Coupe and Cabriolet, the S 450 4MATIC, is powered by the same 3.0-litre, turbo-petrol V6 motor as the previous model, the S400, that produces 367hp and 500Nm of peak torque.
The flagship coupé and cabriolet get the latest V8 petrol engine that is available in the S-Class sedan, namely the twin-turbocharged 4.0-litre V8 mill that makes 468hp and 700Nm of twisting force. The V8 motor features a cylinder shut-off function and makes 13hp more than the older 4.6-litre V8. The new engine in the S560 4Matic helps the coupe hit 100kph in a claimed 4.6sec and go on to an electronically limited top speed of 250kph.
The AMG-spec S 63 Coupe and Cabriolet are powered by a retuned twin-turbo, 4.0-litre, V8 capable of 611hp and 900Nm of peak torque.
The new AMG engine sends power to all-four-wheels via a nine-speed AMG speedshift automatic transmission. The 2018 S63 4Matic+ Coupé has a claimed 0-100kph time of 3.5sec and a limited 250kph top speed.
The top-of-the-line S65 Coupé and Cabriolet get the same twin-turbocharged, 6.0-litre, V12 engine delivering 630hp and 1000Nm of torque to provide 0-100kph acceleration in 4.1sec and the same electronically limited 250kph top speed.
All models have their engines mated to Mercedes’ nine-speed 9G-Tronic automatic ‘box, except the range-topping models, which retain the older seven-speed 7G-Tronic automatic owing to their high torque loads. The S560 Cabriolet as well as the S65 Coupé and Cabriolet will be exclusively rear-wheel driven while the remaining models feature 4Matic four-wheel drive.
