Vehicle Tested 2014 Mercedes-Benz S550 Sedan Driven On 2/10/2014 Ratings Summary As both the flagship of the Mercedes-Benz lineup and a recognized technology leader, the S550 is as sophisticated and luxurious as it is comfortable and fast. Virtually every comfort amenity available today can be had in this big, rapid, opulent sedan.
A
Performance Ample power and adjustable suspension give the S550 near segment-leading performance while still maintaining comfort as a priority. It manages to be fast and capable without ever feeling like it's working hard.
Acceleration
A
With 449 horsepower from its twin-turbo V8, the S550 is downright fast when it needs to be. Our tester hit 60 mph in 4.9 seconds, which is beyond adequate acceleration entering a freeway.
Braking
A
Though it weighs almost 5,000 pounds, the S550 stops from 60 in a distance that would make many sports cars proud. Only 115 feet are required, and its pedal remains solid and responsive.
Steering
B
You'll not forget you're driving a substantial automobile when steering the S550. Steering effort, despite being speed sensitive, is considerable. Feel is adequate but not overbearing. Extremely stable at speed.
Handling
B
Active suspension makes the S550's handling something you'll need time to adjust to, but it's not counterintuitive. Cornering is flat and its limits are quite high for the car's size.
Driveability
A
Though its response in Economy mode is slow, the S550's attitude is adjustable by changing modes. Overall, it's really the car you want it to be, depending on the settings you choose.
A
Comfort Comfort is the S550's strength. It's both smooth and well connected to the road. Inside there's an environment of peace. The cabin is quiet and genuinely adjustable to your liking, right down to the way it smells and the hue of its lighting.
Seating Comfort
A
With front seats that are heated -- and optionally ventilated and massaging -- there's little that could be added to increase comfort. Rear seats offer the same optional features, as well tables and a 43-degree recline function on the passenger side.
Ride Comfort
A
Though its suspension is driver-tuneable over two ranges (Comfort and Sport), the S550's dampers are widely variable and, in comfort mode, are adjusted automatically based on forward-looking cameras. Ride quality is superb.
Quietness
A
Wind and road noise are virtually non-existent in the S550. Noise from its turbocharged engine, too, rarely intrudes into the cabin.
A
Interior As top-end interiors go, the S550's is among the best in materials, ergonomics and comfort. The COMAND system requires a small commitment to learn, but it offers access to most features quickly. Small-item storage could be better.
Ergonomics
A
Driving position is highly adjustable. Critical controls have dedicated buttons. Secondary controls -- signals, wipers, etc. -- follow industry standards. Stalk-activated cruise control is easy to use.
Ingress/Egress
A
Large, detent-free doors stay put where you leave them and are big enough to accommodate easy entry/exit. Even large passengers should have no problems here.
Space/Room
A
Superb room for average-size drivers. Knee and hip room is ample as are head and leg room. Rear seats accommodated our 6'4" passenger. You probably have extreme needs if the S class doesn't meet them.
Visibility
B
Large front roof pillars are a hassle to see around in some instances. Rear quarter visibility could be better, as the S550's rear roof pillar is large and blocks that angle more than we'd like. Overall visibility, though, is OK.
Cargo/Storage
B
At 16.3 cubic feet, the S550's trunk isn't massive. It's average for the class, but for a car this large it could certainly be bigger.
A
Value The S Class comes with a certain reputation to uphold, and this generation meets that standard. If you're looking for the best car in the segment, it's hard to make an argument against this one.
Build Quality (vs. $)
A
Superb assembly quality and top notch materials are expected on the S-Class and are delivered. Excellent.
Features(vs. $)
A
What more features could you ask for in a car that can control its own aroma? The S550 is brimming with features, both standard and optional. It can even, in the right circumstances, drive itself. Asking for more is silliness.
Cost
A
Though it's the most costly among the primary contenders in the large luxury sedan segment, the S550 is truly a car which competes with ultra-luxury marques like Bentley and Rolls. And when considered on those terms, its cost isn't beyond reason.
MPG
C
At 20 mpg combined (17 city/26 highway), the S550's EPA numbers aren't impressive. Our testing produced numbers even lower than the city number despite a large percentage of highway miles. Given its turbo engine and mass, this is hardly surprising.
Warranty
B
The S550 comes with a 4-year/50,000-mile bumper-to-bumper warranty, which is average for the segment.
Ownership
B
Pre-paid maintenance is available but not included. Mbrace -- Mercedes' combination of connected safety technologies -- provides roadside assistance, but is a paid feature.
A
Fun To Drive Though it's no sports car, the S550 is certainly fun to drive. It's big, fast and has genuine presence on the road. It's also a car that you can drive for hours without being fatigued.
Driving Experience
A
Plan on being pampered and indulging in the most modern big-sedan experience available today. No other car offers this much technology designed to make driving comfortable, quick and easy.
Personality
A
The 550 is opulent withough being gaudy. It offers a unique driving experience combined with a statement about its driver's subtle-but-sophisticated taste.
