Mercedes S-class coupe power upgrade

Instead of a 4.7-liter engine, the 2018 S-class coupe uses a 4-liter V8 but with 14 more horsepower thanks to a twin-turbocharger.

A few months after launching the upgraded S-class sedan, the German automaker introduced the 2018 coupe and convertible before bringing them to display at the Frankfurt Motor Show in mid-September in its home country. The car will be sold from mid-2018.

The 2018 S-class coupe gains more power than the current version.

Both the coupe and convertible come in three versions: S560, S63 and S65, the latter two of which are high-performance AMG versions. The S560 replaces the S550 in the lineup and uses a 4.0-liter twin-turbocharged V8 instead of the previous 4.7-liter. Power is up 14 horsepower to 463 horsepower and torque remains unchanged at 700 Nm.

Combined with the new engine is still a 9-speed automatic transmission and Mercedes' 4Matic all-wheel drive system on the coupe, while the convertible only has rear-wheel drive.

The S63 also changes engines, from a 5.5-liter V8 to a 4-liter version from AMG. But instead of losing power, the capacity increases from 557 to 603 horsepower, while torque remains unchanged at 900 Nm. The 7-speed gearbox is also replaced by a new 9-speed from AMG. All versions of the S63 use the 4Matic 4-wheel drive system.

With the S63 version, the engine is still a 6-liter twin-turbocharged V12 and the parameters are also the same: 612 horsepower and maximum torque of 1,001 Nm. Rear-wheel drive and 7-speed automatic transmission.

Aside from the powertrain changes, the 2018 S-Class coupe and convertible are not much different from the 2017 models. The cosmetic upgrades are only subtle. All six models get redesigned front and rear bumpers, new headlights, and OLED taillights. The AMG versions get a grille that follows the design languagePanamericana from AMG GT, giving it a more aggressive look.

Both the S-class coupe and convertible come in three versions: S560, S63 and S65.

Inside, there's a new three-spoke steering wheel and a new version of the Comand infotainment system, with two 12.3-inch screens - one for the digital instrument cluster and one for everything else. Customers can choose from three interior trims, plus a new black-red leather upholstery option.

Comfort and safety features remain unchanged. The coupe and convertible still have massage seats, adaptive cruise control, lane keeping assist, Android Auto/Apple CarPlay...

Both the coupe and convertible won’t be available in dealerships for another year, so the German automaker hasn’t announced pricing yet. Current models start at $124,000 for the S550, $166,000 for the S63, and $237,200 for the S65 coupe. Meanwhile, the 2017 S-Class Convertible starts at $132,400 for the S550, $177,400 for the S63, and $249,000 for the S65.
