The S Class has been the benchmark for the full-size luxury sedan segment for a very long time now. It is the wall that other manufacturers aspire to break down. The S Class is a car that does more than transport people from A to B. It is a symbol of power, wealth and fame. The S Class comes with a feeling of distinction that you have finally arrived there in your life.

The 3.0 Liter V6 engine is good for 362 hp. It would be unwise to think that the S 450 is unrivaled. The full-size luxury sedan segment is privy to some intense competition. The S 450 locks horns with the BMW 740i, Audi A8, and Porsche Panamera sedan.

We Recommend

The Mercedes S 450 4MATIC sedan is available will all-wheel-drivetrain that puts power to the wheels in a more controlled manner and offers better traction in wet and slippery conditions.

2020 Mercedes-Benz S-Class Engine and Performance


"The 3.0-liter twin-turbo V6 has the lowest power output of the four available engines but it's anything but underpowered, even in this big sedan. The S 450 moves smartly away from a stop, and power smoothly builds all the way to redline. There's ample passing power, even at higher speeds."- Edmunds

Back in 2019, the S 450 received a new 3.0 L Biturbo V6 engine that is rated for 362 hp and 369 lb-ft. of torque. The new V6 engine is low by 101 hp and 147 lb-ft. of torque compared when compared to the turbocharged V8 in S 560.

But when you are behind the wheel of an S 450, you would not be disappointed at all. This V6 engine has enough grunt to propel the S 450s real estate, briskly. All that power available on tap, even when you depress the gas pedal it is quick to respond. But unlike the bellowing of a usual gasoline motor, the V6 mill on the S Class displays hush manners. From the cabin, it is really difficult to hear the engine battling out the forces of nature. Such quality is befitting for a luxury sedan!

Transmission duties are taken by 9G Tronic automatic transmission. The gearbox and the engine exist in a perfect symbiosis. And considering the S Class mission of providing an unmatched luxury experience within its oasis. The 9-speed automatic prioritizes early gear changes in favor of comfort and efficiency.

The entry-level products from manufacturers in this segment see a different versions of the 3.0 L turbocharged V6 engine. So, the power outputs from these engines aren't too different on paper. The Beemer pulls off 320 hp from its Twin Power turbo V6 engine, Porsche does a 330 hp, Audi betters it by 5 more hp at 335 hp and the Mercedes beats them all with its 363 hp.


Just a glance at a Mercedes S Class and you know what it stands for! Accomplishing such a feat is very important for a luxury brand. The S 450 wasn't designed to jostle drag strips, or not in any sense it was meant to carve corners through the canyon road.

But don't take S 450 to be a slow-poke, it reaches the 60 mph mark in 5.4 seconds. The S 450 builds up speed without any drama. The quarter-mile marker comes within 13.8 seconds. The S 450 doesn't define "quick" in this segment but it packs enough to fulfill your daily dose of driving.

The competition also sticks close to this sub-5-second mark, except the Porsche Panamera which manages a 4.7-second naught to 60 mph run. When it comes to emissions, test Porsche and BMW farewell than the Audi and Mercedes Benz.

Ride and Handling

It is a distinct feeling with this sedan. Instead of moving on the road it feels like you are flying just 2-inches above the tarmac. That is the level of sophistication Mercedes has been able to come after decades and billions of dollars invested in the S Class.

At lower speeds, the electromechanical steering breathes life into the front wheels of the car. Even for such a size, the S 450 is such a doll at low-speed maneuvers. Driving in the city is never a challenge due to the light steering. The steering weighs up as higher speeds are achieved. Even the precise on-center feel and straight-line stability inspire confidence in drivers.

The superstructure sits upon Airmatic Suspension for a balanced and comfortable ride. The setup uses electronically controlled springs which are more adaptive to driving conditions. This system also lowers ride height to achieve more efficiency and stability at higher speeds.

Adaptive Damping System is embedded with the Airmatic suspension. This system improves ride handling by selecting one of the available four damping profile. These dampening states can also be selected by driver (via selectable drive modes) Sport has firmer setting and bumps are filtered to the cabin, while comfort focuses on reducing the impact from improper road surfaces.


The S 450 is equipped with 13.2-inch brake rotors at the front and 11.8-inch brake rotors at the rear. Weighing in at 4630 lbs. the S 450 is the heaviest sedan amongst this bunch. Due to unavailability of deceleration (60-0 mph) data, we are unable to mention the accurate braking performance of the S 450 sedan.

To provide more control and precision while turning, the S 450 has been fitted with Torque Vectoring Brake system that applies targeted rear wheel braking to compensate for understeer while cornering.

2020 Mercedes-Benz S-Class Fuel Economy

When compared to the larger V8 engine, the smaller V6 engine does have an advantage in fuel efficiency. It also complies better with the stricter EPA emission regulations. The S 450 offers a combined mpg of 22.

The S 450 is equipped with a standard Eco Start/Stop system which switches off the engine when it detects a prolonged idle state. This system works at stop lights and when the driver lifts the foot off the brake pedal. The engine instantly restarts for a prompt response. This system can be a bit sluggish at times.

The completion manages to pull more frugal numbers. BMW and Porsche offer a combined mpg of 24 while the Audi manages a number identical to the Merc.

2020 Mercedes-Benz S-Class Interior

"Good luck finding a vehicle that's more luxurious than this one, at least outside of land yachts from Bentley and Rolls-Royce. The 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." - Cars.USnews

Seating and Comfort

The luxury on offer might make a c ase against many British land yachts. The cabin is a testimony to the billions of dollars that Mercedes has spent on R&D for the S Class. The ride quality is anything like a car. Once you are inside, and you have pulled over the windows. You are isolated from the world.

Comfort and refinement have been pillars for the S Class. Similarly, the S 450 shares the same passion for providing a first class business jet cabin-comfort to the passengers. To take comfort to even superior level, this Merc uses Magic Body Control (optional) system that uses onboard cameras to map the road surface ahead. Then the car adjusts the suspension accordingly to provide a silky-smooth ride.

The seats offer multiple adjustments to provide maximum comfort. These seats are equipped with cooling and heating functions. Heck! Even massage function is embedded within the seats. The S 450 provides an adequate headroom (39.7 inches). The front shoulder room on offer is best in this comparison (59.7 inches).

For those of you, who are likely to be chauffeured in your car? The S 450 has got you covered with a rear seat adjustment that replaces the 3-person bench with two seats.

The central 12.3-inch display is complemented by another 12.3-inch screen which is placed in front of the driver. Both the screens are integrated together and provide a seamless viewing experience. The display is customizable and different instrumentation styles can be selected.

The audio department is handled by the duo of Burmester Surround Sound system and FrontBass system. 13 high-quality speakers and 590- watt 9-channel digital amplifier constitute an audio system worthy of the S Class badge. The twin subwoofers from FrontBass are placed under the dashboard in the front frame of the car accumulating to a precise bass across the interior.

2020 Mercedes-Benz S-Class Exterior


"The S-Class received a minor exterior update last year, but as a whole retains its stateliness-on-wheels motif. It's big, elegant and still relatively conservative - not a bad thing in our eyes. Not one for huge grilles or unnecessary exterior extravagances, the S-Class remains handsomely understated. The "triple-torch" headlights and LED taillights with what Mercedes calls a "stardust" effect are dazzling." -KelleyBlueBook

Dimensions and Weight

Even without the minor tweaks the S 450 was already an accomplished design. The S 450 incorporates a grille that was earlier reserved for the V-12 S class. Though these changes have made the design more assertive, there are subtle components which have been dropped in favor of a newer look.

Dimensionally, the S 450 measures 206.5 inches, 74.8 inches and 58.7 inches at length, width, and height. It surely is a presence that needs a well-prepped garage for its arrival.

When compared, the S 450 is the tallest (74.8 inches) while the Audi A8 L is the longest (207.3) and widest (76.7 inches) sedan in this comparison. Similarly, the Porsche Panamera is the lightest (4001 lbs.) car in this comparison.

2020 Mercedes-Benz S-Class Competition

2020 BMW 740i Sedan

The 7 series does its duty as the flagship car for BMW. The 740i sedan is priced at $ 83,650. Surprisingly there is some terrific competition in the luxury sedan segment. The 740i is powered by a 320 hp turbocharged 3.0-liter inline-six.

The 7 series is a good package but it still cannot match the stellar standards set by the Mercedes S Class. The BMW offers the largest rear cargo (18.2 cu-ft.) space. And the new infotainment system is even more streamlined and easy to use.

2020 Audi A8 L

Starting at $ 83,800 the Audi A8 is offered with a mild hybrid system in 2020. The base sedan is offered with 3.0-liter turbocharged V6 engine that produces 335 hp. The A8 manages to do a lot without compromising on a particular factor, the A8 manages borderline sporty without losing luxury and it is best equipped car of this lot. The all-wheel-drive setup offers confident handling around corners and provides decent grip in wet and slippery conditions.

2020 Porsche Panamera Sedan

Panamera is a different breed of luxury sedan. It is more tuned for sport than luxury. Even the base Panamera is generously equipped with standard features. It comes with Porsche Adaptive suspension, front and rear parking sensors and a parking camera.

With a sticker price of $86,300 the Panamera slots just below the Mercedes S 450 sedan. The Porsche features the lightest curb weight of 4001 lbs. and a very brisk naught to 60 acceleration.

2020 Mercedes-Benz S-Class Final Verdict

The new S 450 sedan might be a little low on power when compared to the previous generation. Even after the power deficit, the 362 hp engine takes care of the mission - to provide luxury above anything else. This refined power delivery of this engine would never leave you wanting for more power.

With the release of the all-new Audi A8 L the S Class is no longer the tech leader in this segment. The S 450 misses out on rear-wheel steering, active suspension and foot massagers. The new update for the S 450 is not happening anytime soon till then we can assume that the Audi A8L will unrivaled in this tech race.

When you are journeying inside the S 450 sedan, you have this cocoon of the car that isolates you from the harsh reality of the outside world. This car simply puts the world on mute. You would pass over potholes and road undulations without the slightest interference to your cabin comfort.
