More tech, increased comfort and a new twin-turbo engine on the way.

Mercedes has detailed changes to its S-Class Coupe and Convertible models ahead of an official unveiling at the Frankfurt motor show

Along the same lines as the changes introduced earlier this year on the S-Class Saloon, there are new engines, bodykits and other changes on the cars for 2018.

What are the changes? 

All models get redesigned front and rear bumpers, new headlights, OLED brake lights – which have varied brightness settings depending on external conditions – and new exhausts. Inside is a new ‘Energising Comfort Interface’ which has pre-set modes to synchronise seat heating and massage functions, ambient lighting, drive modes and even music. The settings include ‘freshness’, ‘warmth’ and ‘vitality’.

The 12.3-inch Comand infotainment setup is now merged with the instrument panel to create what looks like a single screen across the whole of the dashboard – this is what Mercedes calls ‘Widescreen Cockpit’. 

The entry-level S 450 Coupe model gets the changes, but it's not until you arrive at the second model in the line-up that things get spicy.

2018 Mercedes-Benz S560 Coupe/Cabriolet

These models get a new twin-turbo 4-litre V8 engine from the AMG GT and S560 Saloon, which produces 463bhp and 516lb ft of torque. All-wheel drive is now standard on the Coupe, but not available on the Cabriolet model. 

The V8 engine in S560-spec comes with a cylinder deactivation function to boost economy – four of the motor’s eight cylinders can be shut down at once under partial load.

2018 Mercedes-AMG S63 Coupe/Cabriolet

The S63 models get a more powerful version of the twin-turbo 4-litre V8, with 603bhp and 664lb ft matched up with a nine-speed automatic transmission.

Both models get the all-wheel-drive 4Matic+ system as standard. The AMG + version means that torque is fully variable between front and rear. 

There are 20-inch wheels available as standard, and the S63 AMG gets bigger brakes than the standard model. Other performance upgrades include the AMG Track Pace app, performance exhaust and sport Airmatic suspension.

2018 Mercedes-AMG S65 Coupe/Cabriolet

The S65 AMG is the top dog in the range, with a 6-litre twin-turbo V12 that produces 621bhp and 738lb ft. 

It’s not the fastest car in the range – the Coupe’s 0-62mph time of 4.1 seconds is 0.6 seconds slower than the S63 model next down the range. You can guarantee that the engine will be a theatrical experience to behold, however. 

No all-wheel-drive setup here – this could explain the acceleration difference – the S65 is rear-wheel drive only.
