About the 2018 Mercedes-Benz S-Class

6th generation S-Class (W222/V222 sedan, C217 coupe, A217 cabriolet); 2018 is the mid-cycle refresh year for the US lineup.

Mercedes positions the S-Class as its flagship and as a benchmark for big luxury cars: a quiet, beautifully finished car built for effortless long-distance travel, rear-seat comfort, and showcasing the brand’s latest safety and convenience technology. Compared with rivals, the S-Class leans especially hard into ride comfort, cabin craftsmanship, and smooth power delivery. In this era it also offered coupe and cabriolet body styles, giving buyers the same flagship atmosphere in more emotional two-door forms.

The S 450 serves as the comfort-focused core sedan, pairing a 362-hp twin-turbo V6 with air suspension, dual 12.3-inch displays, Apple CarPlay, Android Auto, and Burmester audio. The S 560 is the richer step up, with a 463-hp twin-turbo V8 and Nappa leather, while S 450 4MATIC and S 560 4MATIC models add all-wheel drive.

What changed, by category

Powertrain
The non-AMG gasoline lineup shifts to the S 450 and S 450 4MATIC with a 362-hp 3.0-liter twin-turbo V6, plus the S 560 and S 560 4MATIC with a new 463-hp 4.0-liter twin-turbo V8. The S 550e plug-in hybrid leaves the lineup.
Styling
Mercedes refreshes the grille, headlights, front bumper, and rear bumper. Coupe and cabriolet models also receive revised rear lighting.
Safety
New driver-assistance functions arrive through equipment packages, rather than becoming standard across the entire lineup.
Tech
The cabin gains a revised COMAND touchscreen-control interface, steering-wheel touch controls, standard front wireless phone charging, and Energizing Comfort Control.

“Very comfortable while traveling both short and long distances. It's very comfortable for passengers both on long and short distances.”

“Trunk is smaller than 2016. There is little interior storage space, yet there are multiple ashtrays in the vehicle. Really? Is Mercedes stuck in the 70's? The "SOS not ready" light always on, on the dash is laughable if not so frustrating.”

“Do not get the S450. It is a major step down from the 550. Totally cheapens the Mercedes experience.”
