Both the coupé and convertible come in S560 AMG Line from the off. The entry-level (although still very highly specced) model replaces the outgoing S500 and gets Mercedes' twin-turbocharged 4.0-litre V8 engine in 462bhp form and 516lb ft of torque. AMG's take on the model, the S63, uses a version of the same 4.0-litre V8 but with power raised to 603bhp and 663lb ft of torque. Prices for this model, which will rival the upcoming BMW M8, start at £127,515 for the coupé and £140,610 for the convertible.
The top model on sale is the AMG S65, which is powered by a 621bhp and 738lb ft twin-turbocharged 6.0-litre V12 engine and can hit 62mph in 4.1sec. It costs from £189,615 for the regular car, while those opting for the drop-top version will have to pay £197,510.
First deliveries for the cars will begin in early 2018. Read on for more details.
Revealed at the Frankfurt motor show earlier this year, the upmarket two-door cars adopt a number of subtle styling changes and new OLED tail-lights. Each tail-light incorporates 66 individual OLEDs, providing a distinctive new light graphic. There is also an updated infotainment system and a revised range of interior trims.
Included in the styling makeover are lightly altered bumpers with added chrome highlights, as well as revised sills and chrome-plated tailpipes that mimic those used by the earlier S65 Coupé and Cabriolet.
The performance-oriented models also receive the latest AMG grille treatment, with vertical louvres replacing the former blade design, as well as a front bumper with larger air ducts for more efficient cooling of the engine bay and front brakes.
Inside, there are three new trim lines, as well as the choice of three new upholstery lines. The S-Class Coupé and Cabriolet’s 12.3in digital instrument cluster has been upgraded with revised graphics and the choice of three new themes: Classic, Sport and Progressive. The Comand infotainment system also gets a software upgrade, allowing it to support 3D topographical map displays and Car-to-X messages, among other functions.
Mercedes has also provided its range-topping coupé and cabriolet models with revised driver assistance systems in the form of Active Distance Control Distronic cruise control and Active Steering Assist functions already brought to the S-Class Saloon.
Updated engine line-up
The starting point for the line-up in markets outside of the UK (where the 560 sits at the base) is the S450 4Matic Coupé. It retains the same turbocharged 3.0-litre V6 petrol engine as its predecessor, the S400, with 362bhp and 368lb ft.
The 4.0-litre V8 in the S560 features a cylinder shut-off function for added fuel savings in city driving, providing the car with a claimed 0-62mph time of 4.6sec and limited 155mph top speed. It has a combined consumption of 34.0mpg and CO2 emissions of 183g/km.
The AMG V8 channels its drive through a nine-speed version of AMG’s speedshift automatic gearbox and a revised four-wheel-drive system featuring fully variable apportioning of drive to each axle, endowing the new S63 Coupé with a claimed 0-62mph time of 3.5sec and limited 155mph top speed. It has a combined fuel consumption of 30.3mpg and an official CO2 rating of 211g/km.
The range-topping S65 has a combined fuel consumption of 23.7mpg and CO2 emissions of 279g/km.
All models receive Mercedes’ nine-speed 9G-Tronic automatic gearbox, save for the S65, which retains the older seven-speed 7G-Tronic automatic. The S560 Cabriolet, as well as the S65 Coupé and Cabriolet, are sold exclusively with rear-wheel drive. The remaining models all feature 4Matic four-wheel drive.
Coupé and cabriolet models have accounted for around 15% of total S-Class sales in the UK so far this year.
