As with the 2018 sedan, the S-Class Coupe and Cabriolet undergo relatively modest exterior updates - with the exception of cutting-edge OLED taillights unique to the two-door models. You can select from three distinct graphic presentations - Classic, Sporty and Progression - which will mimic the look of traditional analog instrumentation or deliver a more high-tech presentation. Even though the new 4.0L engine is smaller than the old 5.5L V8 biturbo, the new engine generates 26 more horsepower.
The 2018 S-Class Coupe and Cabriolet get new Intelligent Drive driver assistance systems. Occupants can choose from one of six preprogrammed settings: Freshness, Warmth, Vitality, Joy, Comfort and Training (of which there are three options: muscle relaxation, muscle activation and balance).
The higher versions will be the Mercedes-AMG S63 Coupe and Cabriolet, which will boast the same 603hp, twin-turbo V8 engine. Not being available with an all-wheel drive system, the S 65 is also actually slower to 62mph than the S 63 with a time of 4.1 seconds. Laying down the power to all four wheels is the new AMG SPEEDSHIFT MCT 9G automatic transmission. It is faster than the S560 Cabriolet by 1.2 seconds on a 0-60 miles per hour run while its top speed is locked at 186 miles per hour. On the convertible, things are a little different with only the S63 offered with 4MATIC+ permanent all-wheel drive, leaving the S560 and S65 Cabriolets to be rear-wheel drive.
At the top of the range sits the V12-powered AMG S65.
The S65's horsepower and torque are sent through an AMD Speedshift TCT seven-gear auto transmission to the real wheels, which means the 2.1 tonne vehicle can hit 60mph in a swift 4.1 seconds, with it topping out at an autobahn-eating 155mph.
The S 65 has maintained its twin-turbocharged V12 that produces 620bhp and all the power goes through the rear wheels. For context, the S-Class Coupe range now starts at a little over £100,000, while the S-Class Cabriolet begins at £113,000. There's also a new steering wheel with touch-sensitive controls, something that we've already seen in the new E-Class followed by the new S-Class.
