The Car Connection Mercedes-Benz S Class Overview
The Mercedes-Benz S-Class is royalty, literally and figuratively. The sedan, coupe, or convertible are flagships for the automaker and have served many heads of state for decades.
Along with its traditional four-door sedan body style, the S-Class has absorbed the former CL-Class coupes, and offers convertibles called Cabriolets, as well as the revived, range-topping Maybachs.
With the S-Class, Mercedes-Benz not only has a rival for traditional foes such as the BMW 7-Series and Audi A8, but also for the Bentley Flying Spur and Continental, and even Rolls-Royce sedans, coupes, and convertibles.

The current S-Class made its debut in the 2014 model year, with two-door coupes joining the lineup in 2015, along with AMG performance models, while a Mercedes-Maybach S600 sedan was added for the 2016 model year. For 2017, Mercedes added the Maybach S550 and S650 Cabriolet.
The S-Class received an update for the 2018 model year and momentarily reverted to a sedan-only lineup, though the Maybachs are still available. The updated coupe and Cabriolet were introduced at the Frankfurt auto show in September.
The current S-Class has cycled through powertrains, with new engines arriving with the 2018 update. The new base model, called S450 features a twin-turbocharged 3.0-liter V-6. A new twin-turbo 4.0-liter V-8 resides under the hood of S560 models. It puts out 469 horsepower and 516 pound-feet of torque and is mated to a 9-speed automatic transmission. A more powerful version of that engine powers the AMG S63 model, where it makes 603 hp and 664 lb-ft of torque. Its 9-speed automatic uses a wet starter clutch instead of a torque converter; Mercedes says it saves weight and responds more quickly to throttle inputs. All-wheel drive is standard on the S63, and can run up to 60 mph in 3.5 seconds
Both 4.0-liters shut down four cylinders to save fuel under light load conditions. The S450 and S560 are available with rear- and all-wheel-drive, called 4Matic, while the S63 gets the new 4Matic+ that can vary torque continuously and completely front to rear.
Also offered are the Mercedes-Maybach S650 and Mercedes-AMG S65, both of which feature a 6.0-liter V-12 making 621-hp and 738 lb-ft of torque. The V-12 is paired with a 7-speed automatic. Despite the added power, the S65 AMG is slightly slower to 60 mph than the S63 AMG, due to its rear-drive-only arrangement.
The S560 replaces the S550, which had a 449-hp twin-turbo 4.7-liter V-8. It was mated to a 7-speed automatic transmission, then received the 9-speed for 2017. The S63 was formerly powered by a twin-turbocharged 5.5-liter V-8 churning out 577 hp and 664 lb-ft of torque. Zero to 60 mph took 3.9 seconds.
An S-Class hybrid sedan, dubbed the S550e Plug-In Hybrid, arrived for the 2016 model year and is suspended for 2018. This model featured a twin-turbocharged V-6 paired with an in-transmission electric motor and a lithium-ion battery pack. Electric-only range was about 12 miles, and it achieved an EPA combined fuel economy rating of 26 mpg or a 58 MPGe rating. The S550e employed some clever tricks to get maximum economy, including the use of GPS to determine when a particular driving mode was the most efficient choice.
The standard air suspension with adaptive dampers carries over but the available Magic Ride Control system gets a new feature for 2018. This system uses steel springs with active hydraulics and the new Curve feature tilts the car inward 2.65 degrees in turns to counteract g forces.
Each model in this sixth-generation Mercedes-Benz S-Class is packed with technology aimed at not only entertaining and coddling, but protecting the vehicle’s occupants.
The S-Class's Level 2 self-driving capabilities are updated for 2018 with improved cameras and radar sensors and increased use of map and GPS data. The map data allows the car to slow for twists and turns, as well as junctions.
Inside, the 2018 S-Class adds the Energizing Comfort system that uses the climate control, fragrance diffusion system, ambient lighting, music, seat heaters/coolers, and seat massagers to create five 10-minute programs aimed at helping the driver relax. They have names like Joy and Well-being and the programs range from warm and calming to upbeat and cool. For those who really want to reward themselves, Mercedes offers the Executive Rear Seat Package Plus option package, which adds reclining rear seats with fold-out footrests, a central console with laptop trays, a hot-stone massage function, and heated armrests.
Mercedes relaunched the Maybach brand on the S-Class under the Mercedes-Maybach sub-brand, with its first endeavor being an extra-luxurious version of the S600. This V-12 mega-sedan and the S550 Maybach added for 2017 were stretched compared to the long-wheelbase S-Classes we normally get, with the back-seat passengers benefiting from the extra room.
Finishes and appointments of all Maybachs are a step above those found in standard S-Classes, and the Maybach badge appears in several places inside and out, while the exterior remains very close to the S-Class sedan's look. An even longer version of the Maybach, dubbed Pullman, will also be available for a true, personal limo experience.
Further changes for 2017 included a new Magic Sky Control sunroof option and the mbrace2 Connect package as standard equipment. The Magic Sky Control panoramic sunroof can be adjusted for opacity front and rear. The mbrace 2 Connect package comes with five years of service and includes a mobile app, non-streaming apps, web services, a roadside connection, and diagnostics data.
Though the S-Class can trace its roots to some of the same W-sedan models of the 1950s and 1960s as the E-Class, its true history begins with the 1972 debut of the classically styled W116, the first car to be called an S-Class. Available with a range of 6- and 8-cylinder engines, the first S-Class was one of the first cars to offer airbags, anti-lock brakes, a passenger safety cell, and a turbodiesel engine. The second-generation S-Class, the W126, took over from the W116 in 1980, featuring a completely redesigned, more modern, aerodynamic exterior and an updated chassis. Aluminum-block engines lightened the car, and coupe models were introduced to the range at the middle of the car's cycle. In 1991, the W140 once again led the Mercedes design theme update, bringing an even fresher face and more aerodynamic shape. Some of the extensive features available include double-pane glass, self-closing trunk and doors, and rear-parking markers.
The W220's debut in 1999 marked a change in direction for the S-Class, shrinking in overall exterior size while offering more interior space than the W140. Unfortunately, despite—or perhaps because of—extensive safety, technology, and performance options, the W220 S-Class suffered from a poor reputation for reliability. Nonetheless, it marked the introduction of some of Mercedes-Benz's most innovative safety technology, including the debut of the PreSafe system, a collision avoidance and response system.
The W220 led directly to the W221, introduced in 2005, the fifth S-Class generation. New technology advances included night-vision cameras, the most advanced iteration of Mercedes collision avoidance systems, and, as of 2010, daytime LED running lights. A facelift included LED tail lights and restyled front and rear fascias. Reliability and quality were not been an issue with the W221 the way it was with the W220, with the S-Class winning numerous comparison tests against its competition from BMW and Audi. This generation of S-Class also spawned the Maybach cars, a revived lineup of ultra-luxury sedans that were sold in very limited numbers in the U.S. through the 2012 model year.
Six variants of the sixth-generation S-Class were available, including the S350 turbodiesel and the S400 Hybrid, both with six-cylinder engines; the S550 and the S63 AMG, both twin-turbo V-8s; and the S600 and S65 AMG, both turbocharged V-12s. The S350 BlueTEC made 240 hp and 455 lb-ft of torque, and offered standard all-wheel drive. The S400 Hybrid was the first production lithium-ion hybrid to go on sale in the world, further entrenching the S-Class's reputation for advanced technology. Its 3.5-liter V-6 engine and electric motor combined for a total output of 295 hp. A 7-speed automatic sent the power to the rear wheels.
The S550 sedan was available with all-wheel drive, and featured a 429-hp, 4.6-liter V-8 engine paired with a 7-speed automatic transmission. The S63 had a 5.5-liter twin-turbo V-8 with 536 hp and 590 lb-ft of torque, with thrilling acceleration and all kinds of adaptive electronics for ride and steering. At the top of the range in price and prestige was the S600, powered by a 510-hp, 5.5-liter twin-turbocharged V-12 engine that routed its power through a five-speed automatic transmission, and the S65 AMG, which got its power from a 625-hp, 6.0-liter twin-turbo V-12 engine that churned out a massive 738 lb-ft of torque via a 5-speed automatic. All of that power enabled the big sedan to rocket to 60 mph in just 4.2 seconds.
