2018 Mercedes-Benz S-Class Sedan Review

by Chris Wall

The Mercedes-Benz S-Class is a flagship model aimed at your boss's boss; it's the long and luxurious sedan that others want to be like. The luxury sedan is packed with technology and the most bespoke materials and finishes possible in various combinations, while affording great performance too. The S-Class is available with up to 463 hp from a twin-turbocharged 4.0-liter V8 that's mated to a lightning fast 9-speed automatic transmission and drives all four wheels. Of course, all of this premium fit and finish doesn't come cheap with the base rear-wheel driven S 450 starting off at $89,900 before any options are added

Inside the cabin of a Mercedes-Benz S-Class you'll find top quality luxury everywhere you look. There's a split tone, leather-topped dashboard and the theme wraps around the interior extending along the dash on to the door panels. Once in the power adjustable driver's seat with cooling, heating and a message function, you're faced with a new design multifunction steering wheel that features touch control buttons as found on smartphones. The high raised center console is home to the drive mode dial and more controls for the infotainment system and on board functions. The main focus is the digital instrument cluster that seamlessly joins up with the screen for the infotainment on a large 12.3-inch display. With a car of this size you can expect lots of space, and there is, the rear is almost limousine like, which makes sense, as many people don't really drive an S-Class, they get driven in one. A variety of packages take the tech and luxury even further, and it's all handcrafted.

Driving a Mercedes-Benz S-Class is meant to feel like floating on a cloud when cruising and a sharp and precise tool when driving hard, and that's exactly what it's like. Electronically controlled Airmatic semi-active suspension continually adjusts the ride firmness to keep things smooth or firm and stable, or lowers the ride height at high speed. The 4Matic all-wheel drive system also continually adjusts to maintain optimum traction at all times and works with a 4-wheel electronic traction system and other systems like torque vectoring, electronic stability and active brake assist. These systems are needed because the S-Class is quite rapid with all engine options, especially the more powerful biturbo V8. With so many electronic in play the steering feedback can feel a little dull, but you always know what the car wants to do and where it wants to go. The 9-speed automatic 9G-Tronic transmission has great ratios that not only make the car feel quite quick, it can also be super smooth with almost imperceptible gear changes.

The Mercedes-Benz S-Class is large, but the available powerplants afford the car some rather impressive performance. The S 450 is powered by a twin-turbocharged 3.0-liter V6 with horsepower rated at 362, enough to get the car to 60 mph in 5.1-seconds in rear-wheel drive guise, and that drops to just 4.9-seconds. The bigger capacity 4.0-liter V8 is also twin-turbocharged and is rated a much higher 463 hp with a high 516 lb-ft of torque and as a result, is propelled to 60 mph in as little as 4.6-seconds, a time that defies the car's size. There is an AMG-fettled version too with 603 hp but that's another story.

Equipment & Safety

Mercedes-Benz is synonymous with safety, and it's no different in the S-Class. Systems include active brake assist, adaptive high beam assist, lane keep assist, crosswind and blind spot assist and a first – the Mercedes-Benz Pre-Safe system. This one detects instability in certain situations and prepares the occupants for possible impact by tightening belts and closing the windows and sunroof. Options include a driver assistance package with even more features, an executive rear seat package that makes the car perfect transport for a businessman on the move that includes heated and cooled cup holders. There's also an audio package that features a Burmeister surround sound with FrontBass to rock things up a bit.

That said, buyers in this segment are more concerned with the quality than the pricing.
