2023 Mercedes-Benz S-Class Evaluation, Pricing, and Specs

We think the ultimate luxury item is a powerful engine, so we’d pay extra to have the top-spec 496-hp V-8 and the more prestigious S580 trunk-lid badge.

Engine, Transmission, and Performance

Mercedes offers the S-class sedan with either a 429-hp turbocharged 3.0-liter inline-six-cylinder engine on the S500 or a 496-hp twin-turbo 4.0-liter V-8 on the S580. Both powertrains are supplemented by a 48-volt hybrid system and pair with a nine-speed automatic transmission and 4Matic all-wheel drive. The S580e plug-in hybrid uses an inline-six and an electric motor to pump out 510 horsepower; all-wheel drive is standard here as well. We’ve luxuriated in the S-class sedan and put our test equipment on the V-8 model, which delivered impressive acceleration. While every S-class rides on an air suspension, the optional E-Active Body Control has a “curve” function” that subtly leans the car into corners. The S-class can also be equipped with an all-wheel steering system that makes the big-bodied Merc surprisingly easy to maneuver in tight spaces.

Range, Charging, and Battery Life

While the EPA hasn’t yet weighed in on the S580e’s electric range is yet, we estimate its onboard battery will hold enough electrons to push the S-class around for over 40 miles before needing to fire up the inline-six. A 9.6-kW onboard charger is standard and is good enough for charging at home, but if you’re hoping to quickly juice the battery on a public charger, you should order the optional 60-kW DC charger.

Fuel Economy and Real-World MPG

The six-cylinder S500 is rated at 21 mpg in the city and 30 mpg on the highway. Stepping up to the V-8-powered S580 drops those estimates to 16 mpg city and 25 highway. We’ve tested the latter on our 75-mph fuel-economy route, which is part of our extensive testing regimen, where it achieved 32 mpg on the highway beating its EPA estimate by nearly 10 mpg.

Interior, Comfort, and Cargo

Inside, the S-class prioritizes screens. Lots of them. The sedan is available with up to five, including a giant center touchscreen and a 12.3-inch digital gauge cluster. The latter works in concert with other technology to create a three-dimensional effect, but—thankfully—it can be turned off if you’d prefer the screens to have a conventional appearance. There’s also an enhanced head-up display that will show navigation directions in augmented reality. Basically, arrows move and turn in real-time to supposedly better assist the driver. The build quality and cabin materials live up to Mercedes’ upscale standards, and the sedan provides limousine-like accommodations for all passengers, specifically those riding in the back. The new model’s rear-seat area offers slightly increased headroom and legroom, and it can also be equipped with power-adjustable reclining seats that have massage functions and extensive heating elements. Along with being physically coddled, those in the back should be mentally entertained by the optional rear-seat entertainment system that adds two 11.6-inch screens on the front seatbacks as well as the interactive LED interior lighting.

Infotainment and Connectivity

A cutting-edge infotainment system has become a hallmark of modern luxury cars, and Mercedes makes good on that with its latest and greatest interface. The sedan’s center stack is dominated by a huge 12.8-inch OLED touchscreen that sits portrait-style, but it doesn’t come with any sort of touchpad or rotary controller. What it does come with is an enhanced version of Mercedes’ MBUX software that features improved voice-command functions and smartphone-esque capability, including facial recognition and fingerprint scanning. Of course, popular staples such as wireless Apple CarPlay and Android Auto, and wireless charging are standard. It looks great and has many features but is complicated with multiple screen touches required to access some of the functions. The S-class sedan also has a standard Burmester 3D sound system, but a more powerful Burmester 4D stereo is available, too.

Safety and Driver-Assistance Features

Every four-door S-class comes with an array of standard driver-assistance technology, including the ability to park itself and even take preventative measures to protect passengers when it detects an imminent collision. The sedan is also available with innovative features that include rear-seat airbags and an active suspension that will lift the car up to reduce the severity of damage during a collision. For more information about the S-class’s crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard forward-collision warning and automated emergency braking
• Standard lane-departure warning and lane-keeping assist
• Standard adaptive cruise control with stop-and-go technology

Warranty and Maintenance Coverage

Mercedes has surprisingly mediocre warranty coverage compared with the protection that’s offered by some other luxury brands. For example, Genesis offers a significantly longer limited and powertrain warranty. BMW and Jaguar also have some of the best complimentary maintenance in the biz.

• Limited warranty covers four years or 50,000 miles
• Powertrain warranty covers four years or 50,000 miles
• No complimentary scheduled maintenance
