Mercedes-Benz S-Class

The redesigned S-Class has undergone a significant evolution for 2027. Changes include a fresh look, updated engines, a new computer that’s capable of over-the-air updates, an AI-powered voice assistant, an updated infotainment system with a massive screen, optional heated front seat belts, the chance to personalize interior and exterior colors, and a first-class rear seat experience. A 442-hp turbocharged inline-six cylinder engine is standard, but buyers can opt for a 576-hp inline-six cylinder plug-in hybrid setup or a 530-hp turbocharged V8. Every S-Class gets a nine-speed automatic transmission and all-wheel drive. Air suspension is standard, while an active suspension is optional. Although most features are controlled through a 14.4-inch central display and a 12.3-inch passenger Superscreen display, there are physical controls for some common tasks.

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.

Long considered the benchmark for full-size luxury cars, this version of the Mercedes-Benz S-Class solidly lives up to the model's reputation. The 2014 redesign offered a host of advanced technologies, while upping the luxury ante on many levels. The comprehensive suite of active safety features employs a battery of radar sensors and cameras. Features include active cruise control, lane-keep assist, forward-collision warnings and mitigation, along with attention assist to determine when the driver is drowsy.

There is even an optional fragrance dispenser, which operates automatically at pre-determined intervals to keep the interior of the car smelling nice.

A coupe version was new for 2015. A plug-in hybrid joined the lineup for 2016. 

Updates for 2018 include changes to the model names and their respective powertrains. The S450 is the new entry-level model, powered by a 362-hp twin-turbo V6. V8 and high-performance AMG versions are available. Convertible models are also offered.

The S-Class has always been stately and luxurious. Available in standard and long-wheelbase forms, it has a roomy interior and a large trunk. The ride is comfortable and quiet, and handling is commendable. Engine choices range from a strained inline Six to a more appropriate V8 and even a powerful V12. A new, more advanced S-Class was introduced for 2000. This iteration is much better. It handles nimbly and has excellent ride quality. The CL-Class coupes are essentially two-door S-Class models with altered styling.
