Boasting supreme luxury and cool styling, this loaded flagship sedan leads the field.

When Mercedes-Benz launches a new S-Class, the industry takes note. Always the pinnacle of the German marque’s capabilities, the S-Class brings new tech, features, and styling cues to the lineup, and makes the competition step up its game. Recognized as the sedan that hauls bank executives, dignitaries, and celebrities alike, this Mercedes-Benz icon has serious expectations to conquer.

Competing with the BMW 7 Series, Audi A8, and Maserati Quattroporte, the S-Class will always have rivals at its heels. In its newest form, Mercedes has unveiled its executive sedan to suit the driver as much as the driven occupant. Having reviewed a variety of ultimate luxury sedans including the Rolls-Royce Ghost and Bentley Flying Spur, I wanted to see how a slightly more attainable luxury sedan got along, so I gave it a comprehensive test.

THE KEY SPECIFICATIONS

Mercedes-Benz offers the new S-Class with two different engine options. In the S500, a turbocharged 3.0-liter straight-six (shared with the AMG GT 53 I reviewed) makes its way under the hood, coupled with Mercedes’ EQ Boost 48V mild-hybrid system, producing 429 horsepower and 384 lb-ft of torque. In S580 guise, Mercedes provides its exceptional 4.0-liter biturbo V8, also equips its EQ Boost system, which bumps the output to 496 horsepower and 516 lb-ft of torque. The S580 is driven by a 9-speed automatic that powers all four wheels, and the sprint from 0-60 MPH takes only 4.4 seconds.

At 208 inches long, 77 wide, and 59 tall, the S-Class has a 65-inch front and 66-inch wide rear track, and a wheelbase measuring 126 inches. In its ultimately appointed–and more expensive–Maybach offering, Mercedes extends the wheelbase and overall length seven inches, providing the rear cabin occupants a massive space to be driven in. Thanks to extensive use of aluminum in its construction, this luxobarge tips the scales at just 4,775 pounds.

Mercedes offers the S580 in three distinct trim levels, with the Luxury Line being its standard model, at a base price of $117,700. The upper trim is the Executive Line model, which adds seating and entertainment upgrades to the rear cabin, focused on the driven occupant. The model I tested is the AMG Line, in the middle of the lineup, adding sportier details inside and out, with a base price of $122,000.

Painted Obsidian Black, treated with Sienna Brown and Black Exclusive Nappa leather, and trimmed with Slate high-gloss poplar wood trim, my tester added 22-inch AMG wheels with performance tires, rear-axle steering, the Burmester 4D high-end audio system, warmth and comfort package, night package, and 3D technology package to hit a total MSRP of $142,090.

THE BEST WAY TO COMMUTE TO THE OFFICE

As expected from a car of this caliber, the all-new Mercedes S580 is wonderful to spend time cruising in. While the standard inline-six in the S500 is a good powerplant, the biturbo V8 stuffed into the S580 is the one you want. With its peak 516 lb-ft of torque available from 2,000 – 4,000 RPM, there’s no hesitation when you want the S-Class to surge ahead, complimented by the smoothest torque-ll provided by Mercedes’ EQ Boost mild-hybrid system. Unfortunately Mercedes no longer has a 12-cylinder option in the S-Class, like is standard in the Rolls-Royce Ghost I enjoyed, and is optional in the Bentley Flying Spur and BMW 7 Series.

The S-Class glides over the bumpiest city streets, thanks to its adaptive AIRMATIC suspension that prevents any disruptions inside this massive chassis. Despite being a huge executive sedan, the S580 is remarkably nimble, and the rear-axle steering is a great option box to tick for added agility. Pirelli P zero rubber is wrapped around the 22-inch wheels in the AMG Line, which denitely help it cope in the bends. I took this S-Class along twisty roads on multiple occasions, and was more than pleased with how confidently it carved corners.

The dynamic drive modes offer eco, comfort, sport, and sport plus defaults, and my favorite individual setup involved putting the engine in comfort, the suspension in sport, and the steering in sport too. I liked a hint firmer response–but not too stiff–from the adaptive dampers, as the comfort mode was more floaty than I prefer. Demand even more cornering prowess? Drop $6,500 on the E-Active Body Control that employs a stereo camera system that works in harmony with the 48V electronics in the suspension to minimize body roll, pitch, and dive characteristics under any driving condition. Even if that drive is only made between one’s massive house and the office or country club.

The new S-Class is treated to a cabin that’s upholding the new Mercedes look that perfectly balances cool and luxurious. The S580’s seats are supremely good, with loads of support in the right spots, and heating, ventilation, and massage modes that will spoil you along any drive. The pillows attached to the headrests are a nice touch too. I suggest taking a long road trip to truly exploit the comfort provided in this flagship Mercedes.

The Burmester 3D surround audio system (a $6,730 option) is among the best I’ve heard in any car, even versus the Naim for Bentley system in the Flying Spur and the Bespoke Audio in the Rolls-Royce Ghost I reviewed, detailed with cool metallic speaker grilles (featuring tweeters that unscrew outward when the system is on). If the speakers aren’t potent enough, Mercedes supplies laminated glass that’s heat and noise-insulating, and IR-reflecting, to make sure you aren’t affected by any outside elements.

BEING DRIVEN IN COOL LUXURY

While driving the new Mercedes S580 is great, spending time in the back seat is fantastic. Even without opting for the Maybach model that boasts an extra seven inches of wheelbase that benefits the rear cabin, the legroom rear passengers will enjoy in the S-Class is massive. The optional warmth and comfort package adds rapid heating, cool ventilation, and power adjustments to the rear seats, while also giving the front passengers added heating in the center and door armrests.

If you’re the person being driven more often than driving, spend the extra cash for the Executive Line S580 that enhances the seating setup with massaging modes, a footrest on the right side, four-zone climate control, and upgrades to the MBUX infotainment system to allow for easier controls while utilizing a tablet that docks in the cooler center armrest that also conceals a wireless charging pad.

THE EXCEPTIONAL DETAILS

While the Mercedes-Benz S580’s exterior may project that it’s an understated executive sedan, but there are countless details that make it cool. The sculpted panels carry subtle styling lines that flow smoothly around its body, cleanly connecting the headlights to the taillights. The classic grille contains the cruise control radar components, and there’s still the iconic Mercedes-Benz hood ornament installed.

Under its fine sheetmetal, Mercedes-Benz has gone wild appointing its interior with some of the coolest tech you’ll spot inside any car currently on sale. An additional $3,000 will upgrade the cockpit with an augmented reality heads-up display and a 3D instrument cluster. The 64-color ambient light modes can be adjusted as desired, but I went for the cool Miami Sunset theme that cycles through retro pastel shades.

While cool speakers, ambient lights, and space age materials aren’t new to luxury cars, Mercedes has a party trick few can match, tucked into its infotainment’s settings: “Energizing Comfort” modes. Whether the S580’s occupants are in need of a boost of energy, want to calm themselves after a long day, or have just taken a dose of their favorite psychedelics (please don’t do this and drive), the S-Class will set up a mind-blowing experience.

Depending on the mode selected, an adaptive color theme is introduced through the ambient lights, the seat and armrest heaters crank up if it’s a warming theme or the seat ventilation fans activate, a unique massage mode begins, and the Burmester audio system flexes its prowess as instrumentals blast through all its numerous speakers. It’s an immersive experience like nothing else, and I strongly recommend making friends with a new S-Class owner, wandering to an open space at night, and firing up one of these modes.

THE POSITIVE POINTS

As more luxury manufacturers are making bold styling changes, Mercedes insists on keeping the S-Class refined. Every panel has the tiniest gap that is perfectly measured around the entire body. Soft-close doors silently operate, yet still have a solidly-weighted feel. Door handles are similar to those found on a Tesla Model S, but with smooth and silent extending and concealment when entering or exiting the S-Class.

I expected the new S-Class to be extremely well-assembled inside, but this S580 is exquisite. A blend of big high-resolution displays for the instrument cluster and MBUX infotainment system, fine quilted leather, and cool metal trim that compliments large wood panels complete a cabin I adore. Follow any stitching, wood, or metal trim line, and you’ll never spot a deviation or imperfection. Considering the S580 costs half the price of the Bentley Flying Spur and a third of the cost of a Rolls-Royce Ghost, the interior detailing of the S-Class is on-par with them both.

A FEW TINY COMPLAINTS

Where the complete outer proportions of the Mercedes S-Class are great, the front grille is a little large when presented between the smaller headlamp housings. I get that Mercedes wanted the front-end to be striking, but the main grille element needs to shrink about 20 percent. This is about as much of a complaint as I can find around the S580’s body, as it still looks ridiculously good.

Continuing the trend throughout its updated cabin designs, Mercedes has incorporated more capacitive touch controls for the seat adjustments, and I would prefer some physical movement that’s given more of a positive click when making each of the many seat sections move. The same gripe extends to the steering wheel setup that I didn’t love in the Mercedes E350 I drove not long ago. With physical controls being eliminated, Mercedes makes you take your eyes off the road to adjust the climate control or volume of your favorite music. At least the volume slider adjusts intuitively when you slide your finger either direction.

“THE BEST OR NOTHING” EPITOMIZED

More than a catchy tagline, the principle of “The Best or Nothing” is effectively applied to the new Mercedes S-Class. As is the case each time Mercedes-Benz releases a new S-Class, the luxury flagship benchmark has been reset with this newest edition. Best of luck to the S-Class’ rivals, in an attempt to compete with what is the best offering in its class by far. The S580 demonstrates the finest engineering and craftsmanship Mercedes can produce.

Met with timeless looks outside, the S580’s cabin is treated to wonderfully modern styling touches and a cool factor like no other flagship sedan. Pair a refined chassis with a mild-hybrid powertrain that creates a truly smooth surge, and the Mercedes-Benz S580 is as joyful behind the wheel as it is from the back seat. There’s nothing like a Mercedes-Benz S-Class, and I think it is absolutely the executive sedan to buy.
