2018 Mercedes-Benz S-Class Interior Review


Interior: 9.3

The 2018 Mercedes-Benz S-Class has arguably the nicest interior in the super luxury car class or of any car in any class. The cabin is spacious and quiet, and every surface is dripping with luxury. Both rows of seats are roomy and supremely comfortable, and there are a million features (almost literally). If there is a downside, it’s cargo space. Sedan models have an average-size trunk, but trunks in coupe and cabriolet models are small.

  • "Ultra-luxury sedans from Rolls-Royce and Bentley withstanding, the S-Class cabin remains one of the most opulent available. … Just about every touch point is covered in quality material made from leather, wood or metal. Even the aroma of the cabin itself is special, thanks to the standard Air Balance fragrance system with a replaceable vial of olfactory serum in the glove box." -- Kelley Blue Book
  • "As expected, the interior of the 2018 S-Class sets the benchmark for luxury, but it goes farther than just fine leather and gorgeous design cues." -- Autotrader
  • "Beyond its dynamic attributes, the real beauty of the S-class is its aesthetics. Inside and out, it's a truly special piece that looks and feels worthy of its six-figure price." -- Car and Driver (2017)


S-Class sedan models seat five, while coupe and convertibles seat four. Leather upholstery, 16-way power-adjustable front seats, and heated front seats come standard.

Nappa leather upholstery, rapid-warming front seats, ventilated front seats, massaging front seats, heated and ventilated rear seats (with rapid-warming feature), massaging rear seats, power-adjustable rear seats, folding tables for rear seats, heated armrests, heated and cooled rear cup holders, and a heated steering wheel are available.

No matter where you’re sitting or which body style you’re in, the S-Class has some of the best seats in the automotive industry. Both rows of seats are spacious, supportive, and supremely comfortable, and the numerous comfort upgrades only make things better.

There are two full sets of LATCH connectors for installing car seats. There’s plenty of room for any seat that you want to install, and the LATCH system has no major issues as far as usability is concerned.

  • "The seats, already among the most comfortable and spacious in the industry, are as good as ever, ready for your longest drive." -- Automobile Magazine
  • The 2018 S-Class sedan offers laudable rear-seat room. … By their nature, the S-Class coupe and convertible are tighter in back but still respectable for a 4-seater. One of the few complaints we have is the lack of sliding sun visors." -- Kelley Blue Book
  • "The standard seats are lovely, but we recommend the Premium package's multicontour seats with their additional adjustments, ventilation and six massage settings. That's right, six. One even simulates a hot stone massage by utilizing the seat's heating elements. And just in case your rear passengers are the jealous sort, the same opulent front-seat features (including their adjustments) are available in the sedan's enormous backseat." -- Edmunds (2017)

Interior Features

Standard features in the S-Class include a panoramic sunroof, dual-zone automatic climate control, Mercedes-Benz mbrace Connect (which lets you control some vehicle functions from your phone), a 13-speaker Burmester audio system, satellite radio, HD Radio, Android Auto, Apple CarPlay, Bluetooth, two USB ports, wireless device charging, and the COMAND infotainment system with a 12.3-inch screen, a touchpad controller, and navigation.

Standard driver assistance features include driver drowsiness monitoring, a rearview camera, blind spot monitoring, lane keep assist, crosswind assist, and Mercedes’ Pre-Safe, which automatically tightens seat belts and rolls up windows if it detects an imminent collision.

Available features include quad-zone automatic climate control, three additional mbrace packages, a refrigerator box for the rear cabin, rear-cabin wireless charging, a Wi-Fi hot spot, a 26-speaker Burmester 3-D audio system, a split-view front entertainment system, and a rear-seat entertainment system.

Available active safety features include a head-up display, active lane keep assist, adaptive cruise control, active and evasive steering assist, route-based speed adaptation, active blind spot monitoring and lane change assist, forward collision warning, automatic emergency braking, rear cross traffic alert, night vision assist, a surround-view camera system, parallel and perpendicular park assist, Pre-Safe Rear, Pre-Safe Impulse Side, and Pre-Safe Plus.

The S-Class may have the longest list of standard and available features of any car on the market. These include active safety features you won’t find in every rival, such as driver drowsiness monitoring and semi-autonomous driving technology (almost anything with "assist" in its name in the lists above).

You also have the COMAND infotainment system, which has a large, easily visible screen. It’s not a touch screen, however, so it may take you a while to get the hang of controlling the infotainment system using the touchpad controller.

  • "Look beyond the new engines and you'll find even snazzier stuff with the S-Class electronics. Taking yet another step closer to autonomous driving, the S-Class now uses route-based speed adaption to slow for corners, junctions, roundabouts or toll booths. An active steering system can change lanes following a driver-instigated turn signal, and the aforementioned active brake assist with cross-traffic function uses a long-range radar camera and stereoscopic camera to avoid potential collisions." -- Autoblog
  • "All of the S-Class' many infotainment functions are controlled by the latest iteration of Mercedes' COMAND system, which is reasonably user-friendly given the immense number of functions it's tasked with. Just make sure to spend a lot of time trying things out and asking questions of your Mercedes salesperson." -- Edmunds (2017)
  • "Technology is also on wide display, from twin 12.3-inch high-resolution color screens that relay driving information and infotainment to copious LED lighting." -- Kelley Blue Book (2016)


S-Class sedan models have 16.3 cubic feet of trunk space, which isn’t far off from what other super luxury cars provide. Other body styles have significantly less space, though. Coupe models have just 10.4 cubic feet of space. Cabriolet (convertible) models have 12.4 cubic feet with the top up and 8.8 cubic feet with the top down. A power-closing trunk lid comes standard, and a hands-free power trunk lid is available.

  • The trunk, as you might expect from a 17-foot-long sedan, is sufficiently large. … Note, however, that the available 24-speaker Burmester high-end sound system 'significantly' reduces trunk space, according to Mercedes." -- Edmunds (2017)
