2017 Mercedes-Benz S 550 Engine


"As for engine choice, every S-Class is substantially quicker than you'd expect from such an enormous car. It's really power delivery that's the biggest difference. "-Edmunds

The S550 runs on a beastly 4.7-Liter V8 Biturbo engine. Power comes linearly and without any lag, evenly spread over the entire rev-range. The engine redirects a portion of exhaust gases back into the combustion chamber in order to increase power and efficiency. The performance, however, is much gentler than the figures suggest.

When you're driving around, the surrounding populace would immediately know this isn't an AMG. Even with the throttle pinned to the floor, the engine simply refuses to growl. There might be a faint rumble, but none that excites. That can also be attributed to the 9-speed Automatic transmission which is tuned for efficiency, and not performance. The shifts are smooth and help the car and the driver for a smooth ride and shifts. Here are some stats for your indulgence.

Power 449hp 320 hp 333 hp 340hp
Torque 516 lb.-ft 330lb-ft 325 lb-ft 332 lb.-ft

Unlike the Mercedes, BMW, Audi, and Jaguar have proper "small" offerings for the base models in their luxury sedan lineup. All three sport a 3-liter engine in either a "V" or an inline configuration. 


The engine's power fights the heft of the car when setting off the line. The S550 isn't nimble or agile. What it is, is a huge luxury sedan for passengers in the back seat. The acceleration isn't slow though; it takes under 5 seconds to reach 60 mph from a standstill, and just under 13 seconds for a quarter mile.

Models Mercedes-Benz S 550 Sedan BMW 740i Sedan Audi A8 3.0 TFSI Jaguar XJ R-Sport
0-60 MPH 4.8 sec 5.4 sec 5.5 sec 5.4 sec
Quarter mile 12.9 sec 13.4 sec 13.8 sec 14 sec
Engine 4.7L 3.0L 3.0L 3.0L
Emission (Tons/yr. of CO2 Emissions @ mi/year) 8.4 7.4 8.1 8.4

In a Quarter mile race, the competition loses owing to their smaller engines. The emission though, is also lower, with BMW being the most environmentally conscious of the lot.

Ride and Handling

If you expect the S-class to offer anything other than a magic carpet tide, then raise your expectations. It uses its air suspension along with active dampers to great effect. Like a cruise ship, the S550 floats on the tarmac, smoothening every little bump.

Usually, good ride quality comes at the expense of handling. This isn't exactly the case with S550 though, with only the sharpest of turns inducing body roll. The steering isn't extremely responsive and there isn't much fun to be had here, due to the lack of feedback.


The S550 has a really impressive braking performance for a car of such massive dimensions. The brake pedal feedback isn't progressive. You can never know how hard the calipers are biting down the discs, although the ABS would save you in case you bake too hard.

Curb Weight(lbs) 4773 4195 4464 3891
60-0 MPH (ft.) 117 112 118 122

The Beemer and the Jag both have great feedback from the brakes, although XJ's braking distance disappoints a little. Overall, the competition performs just as good as the S550.

2017 Mercedes-Benz S 550 Fuel Economy


Although fuel efficiency isn't the first concern for S550, it helps to know the figures, especially if you drive around a lot. The city efficiency is a moderate 18 miles per gallon, while the highway efficiency rises to 26 miles for every gallon.

MPG (City) 18 21 19 18
MPG (Highway) 26 29 29 27
MPG (Combined) 21 24 22 21

In terms of both city and highway efficiency figures, BMW 740i knocks everyone out of the park. Audi A8 follows behind closely, while the Jaguar XJ R-Sport offers the same figures as the S550.

2017 Mercedes-Benz S 550 Interior


"Looking for the swankiest interior around? Look no further than this Mercedes, which cocoons you in luxury thanks to a quiet, stylish cabin built with the finest materials."-Cars.USnews

Seating and Comfort

Comfort is where the Merc excels. Seating only five people in such a huge space leaves plenty of room for everyone. Most of the luxury is centered around the rear passengers, as this car is meant to be chauffeur driven for the majority of its life. Even the tallest of passengers would appreciate the leg and headroom inside.

There are 8 options for seat upholstery, 8 different colors for the leather, and another 6 colors for the wooden inserts. The potential for customization is high, and you are sure to find the perfect cabin according to your taste. Fans of chilled beverages will find joy in the optional refrigerator, although the storage capacity in it is very limited.

Passenger capacity 5 5 5 5
Front (Head/Shoulder/Leg) (In.) 39.7/59.7/41.4 39.9/59.2/41.4 37.2/59.1/41.4 39.5/57.6/41.5

BMW 7 series offers just a little more space than the S-Class, especially in the back seats. The A8 has the same interior space as the Merc, and the Jaguar comes dead last, with the least impressive rear seat room.

Infotainment System

For 2017, S-class uses its signature COMAND infotainment system with a knob, touchpad, and dual 12.3-inch display setup. Some standard features on offer are:

  • 4G LTE
  • Bluetooth Audio and Phone connectivity
  • Real-time traffic navigation
  • Real-time Weather and traffic
  • Voice Command\
  • Apple CarPlay and Android Auto aren't on offer, even as optional extras.

Cargo Capacity

Trunk volume for S550 is somewhat disappointing. 16 cubic feet is average for this segment. The optional refrigerator, which might rob the trunk space even further, although you can fit all you might need for a weekend getaway.

Volume (ft cube) 16.3 18.2 14.2 15.2

BMW engineers have cunningly designed the 7-series with just a bit more space in the trunk than its competitors. The XJ and A8 fare poorly, with their cargo capacity falling well below average.

2017 Mercedes-Benz S 550 Exterior


"Sedan, coupe and convertible alike show a clean, smooth face to the wind, with graceful lines flowing from nose to tail. The coupe is a true pillarless hardtop, while S600 and AMG models are distinguished by dual tailpipes and more aggressive front-end styling."-KelleyBlueBook

Dimension and Weight

The dimensions remain the same as the previous model, in both length and width. The near 125-inch wheelbase liberates large amounts of space inside, although the turning circle gets compromised. The weight is the same story, and the vast expanses of metal tip the scales at almost 4800 pounds.

Track width(in) F/R 63.9/64.5 63.5/64.6 64.7/64.4 64/63.1

The Jag is the lightest of the bunch here, although that offers no advantage in terms of performance. Its wheelbase is also the smallest, helping the handling a little at the expense of rear legroom.

Exterior Features

The Mercedes S 550 Sedan has the following exterior features:

  • Rear Trunklid Spoiler
  • Wheel Locks
  • Electrically Heated Windshield
  • Rear Decklid Badges Delete

2017 Mercedes-Benz S 550 Competition

Mercedes-Benz S550 vs BMW 740i

BMW has endowed the 7-series with their and priciest tech and luxury. Even with the smaller engine, the 740i holds its own against the S550, not that the target demographic would care. The appeal lies in the rear seat comfort, and that is well taken care of.

If you are the kind that looking for respect on road, both the Merc and the Beemer will do you proud. There is really not much difference between the two, and the final decision could be based on personal preference.

Mercedes-Benz S550 vs Audi A8 3.0 TFSI

The Audi A8 combines relatively plain looks on the outside with extreme comfort on the inside to give you the ultimate understated luxury car. It wouldn't attract much attention on the road, perfect for the distinguished gentleman and lady.

On the downside, it doesn't attract much attention, which could be a problem for the people who like to announce their arrival. If you are looking for a statement rather than a set of wheels, the A8 would be the poorer choice.

Mercedes-Benz S550 vs Jaguar XJ R-Sport

Based solely on visual appeal, XJ wins without even a fight. The chiseled headlamps, the beautifully symmetrical proportions, the flowing lines on the exterior, all come together to form one handsome car. The interiors are lively, the seats hug you like your mother, and its speakers play the exhaust tune inside the cabin for a more engaging experience.

The interior space is the worst in class though, especially in the rear. If you are to be chauffeured around, it's better to be chauffeured around in the S-Class.

2017 Mercedes-Benz S 550 Final Verdict

The lowest model in Mercedes' luxury lineup, the S550 works hard to hide its shortcomings which, to be honest, are many. It makes for a great alternative to the more premium S600, and possibly better value for money too.

If you ever find yourself in the market for ultimate luxury and three-point star branding but don't feel like shelling out more money than necessary, the baby S-class is the car for you.
