2021 Mercedes-Benz S-Class

Pros: Showcase of leading-edge high-tech features; spacious, coddling interior with outstanding materials quality

Cons: Prices start north of $100,000; numerous tech features can be hard to master

CG Says: Mercedes-Benz’s flagship S-Class sedan is redesigned for 2021, gaining all-new styling inside and out, standard all-wheel drive, and a host of new high-tech features. S-Class coupes and convertibles are carryovers from the previous generation and are not expected to be replaced on the new platform. For now, the new sedan is available in three versions: base S 500, S 580, and ultra-luxury Mercedes-Maybach S 580 (which has a 7-inch-longer wheelbase for increased back-seat room). High-performance AMG models are expected join the lineup for the 2022 model year. The S 500 is powered by a 429-horsepower turbocharged 3.0-liter inline six; the S 580s have a 496-hp biturbo 4.0-liter V8. Both engines are paired with Mercedes’ EQ Boost 48-volt mild-hybrid system and a 9-speed automatic transmission. The S-Class coupes and convertibles continue to come in S 560 form (with a 463-hp turbo 4.0-liter V8) and AMG S 63 trim (with a 603-hp turbo 4.0-liter V8). Among the sedan’s new available features are a rear-steering system that can reduce the vehicle’s turning circle by seven feet, a 3D digital instrument panel, ambient interior lighting that flashes red to alert the driver of hazards, and a head-up display which can project augmented-reality directional arrows to highlight turns for a navigation-system route. More than 50 electronic components have software that is capable of receiving “over-the-air” updates via the Internet. Available safety features include automatic emergency braking, active blind-spot assist, active lane-change assist, adaptive cruise control with stop and go, evasive steering assist, active speed-limit assist, cross-traffic brake assist, lane-keep assist, exit assist, rear airbags (mounted on the front seatbacks), and “Car-to-X” communication (which uses radio-based technology to exchange information about the road ahead and warn drivers of possible hazards). A novel new optional feature is an adjustable suspension that can raise the car when an impending side impact is detected and reduce the impact on occupants. The redesigned 2021 Mercedes-Benz S-Class sedan gets even more expensive than before, but it stays on the cutting-edge of luxury and technology… and it’s poised to continue to excel at pampering its demanding clientele.
