2018 Mercedes-Benz S-Class

Pros

  • Ample power with any engine choice
  • Opulent interior with plenty of customization options
  • A smooth ride no matter what the road surface
  • Silent cabin that insulates occupants from the outside world

Cons

  • Some driver assistance options have questionable value
  • Not as engaging to drive as some rivals


Which S-Class does Edmunds recommend?

Even though the term "entry-level" may not be readily relatable to "premium luxury," the latest model addition to the stately 2018 Mercedes-Benz S-Class lineup is our pick. The new S 450 makes about 100 fewer horsepower than the S 560, but it still has more power than most drivers will ever need. Sure, there's something to be said for one-upmanship at this lofty level, but exchanging a bit of power for the cost savings is worth it in our opinion. Plus, the S 450 has all of the S 560's standard features and is eligible for just as many options.

Edmunds' Expert Review

Overall rating

As the current generation Mercedes-Benz S-Class reaches the halfway point in its life cycle, it receives the customary refreshening to keep it competitive against newer rivals. Those include the BMW 7 Series, Porsche Panamera and next year's redesigned Audi A8. To its credit, the S-Class would have remained a top pick in the premium luxury sedan class without the subtle styling tweaks and added features. That's how good it already was.

A slightly more affordable S 450 model debuts this year. Its V6 is down on horsepower compared to the S 560's larger V6, but otherwise it has the same exhaustive list of features. It's the best value here. The new driver assistance features aren't as well-executed as we would have expected, or as advanced as they might be portrayed, so we're more inclined to pass on those options. What you're left with is a stately sedan with an impeccable interior and a smooth ride that keeps occupants blissfully isolated from the harsh outside world. Quite simply, the 2018 Mercedes-Benz S-Class exceeds expectations.

Trim levels & features

The 2018 Mercedes-Benz S-Class is available as a five-passenger sedan, four-passenger coupe and convertible (cabriolet).

The S450 is available as a sedan only while the S560, AMG S63 and AMG S65 are offered in all three body styles. The main difference among these trims is what's under the hood.

Starting things off is the S450 sedan. It's powered by a turbocharged 3.0-liter V6 engine (362 horsepower, 369 pound-feet of torque) that sends power to the rear wheels through a nine-speed automatic transmission. Mercedes' 4Matic all-wheel-drive system is available as an option.

The S560 has a turbocharged 4.0-liter V8 engine (463 hp, 516 lb-ft) but is otherwise equipped similarly. The all-wheel-drive system is standard on the S560 coupe but not available on the convertible.

Standard feature highlights include adaptive LED headlights, auto-dimming and power-folding mirrors, a panoramic sunroof, a power trunklid, an air-ride adaptive suspension, keyless ignition and soft-close doors. On the inside, you get a virtual instrument panel, leather upholstery, 16-way power-adjustable front seats (with heating and memory functions), an air fragrancer and a power rear sunshade.

On the tech front, the S-Class comes with remote control over some features via a smartphone app, a wireless charging pad, a 115-volt household power outlet, a 12.3-inch display with Mercedes' COMAND infotainment system, a navigation system, Apple CarPlay and Android Auto, and a 13-speaker Burmester surround-sound system. Standard safety features include forward collision warning with automatic emergency braking, blind-spot monitoring, lane departure warning, and a drowsy driver warning system.

The S560 coupe and convertible add ventilated front seats, premium leather and an automated parking system but go without the household power outlet and rear sunshade. The convertible also features a folding soft top, Airscarf neck heating, and the Aircap system that deploys wind blockers atop the windshield and between the rear headrests.

Naturally, Mercedes offers a wealth of options to further solidify the S-Class' luxury status. You'll probably want the Premium package, which includes front multicontour seats with massage functions with instant heating and a surround-view camera system for the coupe and convertible while the sedan also adds ventilated front seats, power rear sunshades and the automated parking system. A head-up display is also included for the coupe and convertible. If safety is a priority, the Driver Assistance package bundles a wide assortment of advanced driver safety aids.

To keep rear passengers completely comfortable, there's the Executive Rear Seat package for the sedans with its multicontour seats with massage functions and a power-reclining right rear seat with ottoman and seat cushion airbags. There's also an optional Executive Rear Seat Plus package that replaces the center seat with a console and includes an entertainment system and refrigerated compartment.

Other add-ons include Magic Sky Control (dimming tint for the sunroof), Magic Body Control (a predictive suspension for sedans with a tilting function when cornering), a night-vision camera, a head-up display, a rear-seat wireless charging pad and a 26-speaker premium Burmester audio system.

The AMG S63 has a sportier take on luxury with a turbocharged 4.0-liter V8 (603 hp, 664 lb-ft). A performance-tuned all-wheel-drive system is standard along with unique exterior treatments. The AMG S65 ups the ante with a turbocharged 6.0-liter V12 (621 hp, 738 lb-ft) and is only available with rear-wheel drive.

The AMG models include the Premium package, 20-inch wheels, upgraded brakes, an adaptive sport suspension, a sport exhaust, unique sport modes and performance apps, the surround-view camera and an IWC clock (sedan only). The S65 adds further enticement with standard Magic Body Control, a leather headliner, the premium audio system and the night-vision system.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our First Drive of the Mercedes-Benz S 450 4Matic Sedan (turbo 3.0L V6 | 9-speed automatic | AWD).

Driving

Don't think that the new V6-powered S 450 base model is any less capable than the traditional V8-powered S 560. Even though it's at a 101-hp disadvantage, there's more than enough power for the typical driver.

Acceleration

The S 450 gets up to highway speeds with ease. Mercedes estimates it will reach 60 mph in 4.8 seconds with the 4Matic all-wheel-drive system (5.0 in standard rear-wheel-drive). This is only about 0.4 second slower than the V8-powered S 560.

Braking

The brake pedal is moderately firm and easy to modulate, making it appropriate for a large luxury sedan. Under heavier braking, the S 450 is confidently poised and controllable.

Steering

Steering is effortlessly light at parking lot speeds and builds as speed increases. On the highway, maintaining a straight cruising line requires very little effort on the part of the driver. There's very little feedback, but it's not missed in a big luxury sedan like this.

Handling

You feel all of the weight of the S-Class when cornering, but it goes around turns with little drama. It doesn't encourage aggressive driving, but there is an underlying confidence that it is capable of swerving around obstacles without losing control.

Drivability

The S 450 is very easy to drive, requiring little effort from the driver. The sheer size of the car is a hindrance in very tight spaces.

Comfort

If there's one thing we've come to expect from an S-Class, it's comfort, and this latest model meets those expectations. At a time when some rivals are sharing the focus with performance, Mercedes concentrates more on refinement and it pays off.

Seat comfort

The optional multicontour seats are as comfortable as seats get. In addition to the numerous adjustments that provide plenty of range, the massage functions, heating and ventilation will pamper you in style. The available executive rear seats are equally decadent.

Ride comfort

The S-Class' standard suspension does an admirable job of smoothing over rough pavement. It's as good as or better than its impressive rivals. With the additional Magic Body Control option, you will almost feel as if you're floating above the road.

Noise & vibration

Very little outside noise makes its way into the cabin. Road and wind noise is virtually absent. This is precisely what you'd expect from a premium luxury sedan.

Climate control

With six vents for the front seats, air can be distributed just how you want. The automatic climate control functions flawlessly and needs little or no adjustment once set. The heated and ventilated seats are equally effective.

Interior

As is customary with the S-Class, the interior is impeccable. Materials quality is as good as it gets, while the thoughtful and attractive design justify the lofty price. The same holds true when you add options that further dress up the cabin.

Ease of use

The primary controls are well-labeled and located for ease of use. Other functions can be controlled via the COMAND dial that rests right under your hand.

Getting in/getting out

Big, wide openings and soft-close doors make it easy to get in and out of the S-Class. You do have to shimmy a bit when parked in tight spots, but the doors are thin enough to keep it from being a problem.

Driving position

Drivers of any shape and size will find their optimal position given the plentiful adjustments and range within them.

Roominess

There's no shortage of space in the S-Class no matter where you're seated. Both front and rear seats have a wealth of room in every dimension to stretch out.

Visibility

The roof pillars obstruct outward visibility slightly, but not to a degree that is worrisome. The standard rearview camera makes backing into a spot easier, and the available surround-view camera takes away any remaining guesswork.

Quality

Every interior surface is of the highest quality, whether it's leather, metal, wood or plastic. All of these elements meet the expectations for a luxury sedan as expensive as the S-Class.

Utility

Luxury sedans generally have generous trunks and plenty of places to store your personal items, and the Mercedes S-Class is about average among cars in this class.

Small-item storage

The moderately sized bins and cupholders are sufficient to hold all of your personal effects. The optional Executive Rear Seat Plus package delivers the same kind of storage for your backseat passengers.

Cargo space

The 16-cubic-foot trunk is average size for the class and will easily accommodate a large complement of luggage and golf bags. The liftover height is low and is enhanced with available hands-free activation. But opting for the premium audio upgrade will reduce the capacity to 12 cubic feet.

More about the 2018 Mercedes-Benz S-Class

The 2018 Mercedes-Benz S-Class sedan is just a bit more accessible than its predecessors thanks to a new entry-level model. Starting at $90,000, the V6-powered S450 costs about $10,000 less than the traditional V8-powered S560. Beyond that, the sportier and more powerful AMG S63 and AMG S65 push well past the $150,000 mark. At the pinnacle of luxury are the Mercedes-Maybach models that are covered separately. The 2018 S-Class coupe and convertible follow similar pricing and feature structures.

Standard feature highlights include 18-inch wheels, adaptive LED headlights, a panoramic sunroof, a power trunklid, an air-ride adaptive suspension, soft-close doors, automatic climate control, leather upholstery, an air fragrancer, a power rear sunshade, a 12.3-inch display with Mercedes' COMAND infotainment system, a navigation system, Apple CarPlay and Android Auto, and a 13-speaker Burmester surround-sound system. Standard safety features include forward collision warning and mitigation, a rearview camera, blind-spot monitoring, lane keeping assist and a drowsy driver warning system.

The S560 coupe and convertible add ventilated front seats, premium leather and an automated parking system. The convertible also features a folding soft top, Airscarf neck heating, and the Aircap system that deploys wind blockers atop the windshield and between the rear headrests.

The optional Premium package additions include ventilated front multicontour seats with massage functions and instant heating, power rear window sunshades, an automated parking system, a surround-view camera system and a hands-free trunk opener. It's a prerequisite for other add-ons such as the Executive Rear Seat package (rear multicontour seats with massage functions and seat-cushion airbags) and the Executive Rear Seat Plus package (adds a center console, heated and cooled cupholders, and two fold-out tables).

Should I lease or buy a 2018 Mercedes-Benz S-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
