Why it stands out

The 2018 Mercedes-Benz S-Class stands out because it sits at the center of Mercedes-Benz’s long-running flagship tradition, where advanced technology and fine craftsmanship are the main priorities. In this generation, the car was designed to be a technological showcase, with the W222 series bringing a new aluminum hybrid body shell that cut weight and improved rigidity, plus a cabin that made generous use of wood and metal accents. It also featured selectable ambient lighting, which helped define the interior atmosphere, and the model’s dual 12.3-inch screens gave it a modern, high-end presentation that still feels distinctive.

For 2018 specifically, the lineup included the S 560 with a 4.0-liter V8 making 463 horsepower and 516 pound-feet of torque, the S 450 with a twin-turbo 3.0-liter V6 making 362 horsepower and 369 pound-feet of torque, and the AMG S 63 with 577 horsepower and 664 pound-feet of torque. The year also kept the plug-in hybrid S 560e in the mix, with 469 system horsepower and 30 miles of electric range. That combination of strong performance, hybrid efficiency, and luxury equipment is a big part of the car’s appeal, especially for buyers who want a full-size sedan that feels both powerful and deeply refined.

At the same time, the 2018 S-Class is not a simple or inexpensive car to own. The source notes that many of its best features were optional, and that the car remains expensive to maintain even though the W222 has a very good reliability record overall. It is also a large vehicle, so its size can be a drawback for some drivers, but for buyers who want a lavish, technically advanced luxury sedan, that scale is part of the experience.
