2021 Mercedes-Benz S-Class

Most Mercedes-Benzes give their owners industry-leading comfort and technology. The cost of that experience is an expensive base price with expensive options and below-average reliability. The brand produces a wide variety of vehicles for the U.S., including coupes, station wagons, sedans, convertibles, and even two-seat sports cars. Its two- and three-row SUVs that we’ve tested have powerful engines and interiors that are roomy and quiet. Generally, Mercedes-Benz fit and finish, inside and out, is exceptional and helps justify prices. Mercedes-Benz’s EVs range from compact to large three-row SUVs. Across the lineup, controls for the complex climate and infotainment systems aren’t as intuitive as we find in other luxury vehicles. Like most European luxury brands, used Mercedes-Benzes can have expensive out-of-warranty repairs, although Consumer Reports has found used models with above-average reliability.

The S-Class has always been the epitome of an ultra luxury sedan. This redesigned flagship sedan continues to deliver a very comfortable ride but the low profile tires mar it. The cabin is super hushed, fit and finish is impeccable, and thrust is effortless. The standard engine is a 3.0-liter inline-six cylinder, and the uplevel choice is a 4.0-liter V8, both turbocharged. Each is teamed with a nine-speed automatic transmission and supplemented with a 48-volt mild-hybrid system. The car's rear-wheel steering turns the wheels in the direction of travel to aid handling and in the opposite direction to aid maneuverability. That in turn makes the S-Class quite agile in the corners, belying its size. The new infotainment system is complicated to use. The slick head-up display features augmented reality. Safety innovations include the ability to raise the ride height to better protect passengers during a side impact.
