The 2026 Mercedes-Benz S-Class is a full-size luxury four-door sedan that serves as Mercedes-Benz's flagship model in the segment. Comparable vehicles include the BMW 7 Series, Audi A8, and Genesis G90. Built on the W223 platform introduced in 2021, the 2026 model receives a mid-cycle refresh with exterior updates such as redesigned headlights, an enlarged grille, new wheel designs, and additional customization options including more paint colors, leather selections, and trim packages. The base S 500 4MATIC model pairs a turbocharged 3.0-liter inline-six mild-hybrid engine producing 442 horsepower with a nine-speed automatic transmission and all-wheel drive. EPA-rated fuel economy stands at 20 mpg city, 29 mpg highway, and 23 mpg combined.
The S-Class incorporates the updated MBUX infotainment system featuring an MBUX Superscreen that merges the central and front-passenger displays under a single glass surface, accompanied by a 12.3-inch digital instrument cluster. Standard connectivity includes wireless Apple CarPlay and Android Auto, along with fingerprint and facial recognition for user profiles and voice controls that process natural-language commands for climate, navigation, and media functions. For 2026, MBUX software sees refinements, while optional packages expand rear-seat features: the Pinnacle package offers executive seating with massage capabilities, and the Exclusive package provides heated armrests and power rear adjustments. Available driver aids include adaptive cruise control with lane centering. The Mercedes me connect app supports remote preconditioning and vehicle monitoring, with over-the-air updates for ongoing improvements.
