Handling and Steering

Most of the people buy the E Class because they want to reach their destination as comfortably as possible. The suspension is pretty good at tackling road undulations and the interior space is super quiet. If it is fitted with optional air suspension, the ride feels as if you're on a cushion that floats over bumps.

The E 400 is equally relaxing in town as on the highway. The 9G-TRONIC gearbox is slick and provides for quick gear changes when overtaking is required and wafts along when you just feel like cruising on the endless roads.

Braking

Mercedes Benz E400 is equipped with 14.2-inch ventilated front and 12.6 inches rear discs. E400 weighs in at 4,034 pounds. Braking test results are unavailable for E400.

Interior

9.0/10

"When Mercedes' latest S-Class flagship sedan debuted a few years ago, its cabin became the benchmark for mainstream luxury opulence. The latest E-Class, which was all-new just last year, took many of its bigger brother's fineries and bettered them in some ways" - Kelley Blue Book

E400's cabin is masterfully crafted with genuine leather and on the whole feels like the S-class as soon as you get inside the car. The front has got these 4 vents and a giant 12.3-inch high-resolution central infotainment screen.

There is no digital driver cockpit which should have been standard instead of the 2 big analog dials and small multi-function display in the center. The steering mounted controls with touchpad make it super easy to control every feature.

Seating and Comfort

E400 is super spacious from the inside. Its supportive front seats come with electrical adjustment and memory system to make you feel comfortable. You even get 4-way electrically adjustable lumbar support as standard to help reduce a backache on long journeys.

Both front seats come with height adjustment. The back seats are made easy by the wide rear door openings. There's more than enough leg and headroom for passengers over 6-foot tall to get comfortable. Also, with a 40/20/40 split, it offers a variety of cargo and passenger configurations.

In terms of interior space, Cadillac has the best front headroom and legroom at 40.4 inches and 45.7 inches. BMW has the best front shoulder room at 58.7 inches. At the back, BMW 540i has the best rear headroom at 38.8 inches, Mercedes E400 has the best shoulder room at 57.1 inches.

Infotainment

The standard satellite navigation system is good but not like AMG models as they get enhanced features. The shortcut buttons to use the beautiful infotainment are placed in the natural hand-resting position when driving the car.

To work the touchpad a bit of skill is needed but when you drive it daily, it gets to you and you feel very connected. The only let down is the driver's cockpit doesn't have the digital setting instead it gets 2 big dials and small multi-function display.

Cargo Space

E400 boot space is 13.1 cu ft. There's more than enough space to carry bags or large suitcases but the Mercedes raised boot opening means it's not quite as easy to pack full of bulky items.

Exterior

8.1/10

"The classy exterior styling looks right at home alongside Mercedes-Benz's other sedans, and it will undoubtedly stand the test of time. Its dimensions give the E-class luxury-car presence without being unwieldy to park or maneuver around the city." - Car and Driver

We know the design is highly subjective, but we're head over heels with the way E 400 looks. The alloys are 18 inches, there is a power tilt and slide sunroof and the polished aluminum strips on the doors and windows give it a luxurious look.

The design of the car looks absolutely purposeful and premium which you want at this price but there is one element that does look a bit too weird. The way the front grille sticks out in front of the headlight which from some angles looks like it got an extended nose job done but all in all it looks perfect.

Dimensions and Weight

2018 Mercedes Benz AMG E43 is 193.8 inches in length and 81.3 inches in width. Wheelbase is 115.7 inches which provide for ample amount of space and comfort for the passengers. Height is 57 inches which provide for good aerodynamic stance. The E 400 weighs in at 4034 pounds.

Competition

Mercedes-Benz E400 vs Audi A6

Audi A6 is almost $9,000 cheap than Mercedes E400. This might affect the purchase decision of the buyer. It's 3.0 L TFSI V6 engine is truly a treat if you look for performance and mileage. It has 340 horses that also deliver impressive fuel economy thanks to its 8-speed transmission.

Mercedes-Benz E400 vs BMW 540i

New BMW 5 series is an excellent saloon that's sportier than E class. Previous gen BMW had curves, but new gen gets a little sharper in styling whereas the E400 is elegant and curves. The interior quality of both cars is absolutely stunning.

The seats in both are comfy and provide maximum comfort but BMW 540i XDrive has an edge over E class wheelbase which increases the space inside the cabin. Also, the boot of E400 is less in volume as compared to BMW.

Mercedes-Benz E400 vs Cadillac CTS

Ah! Germany vs USA and E class is in a league of its own. Cadillac does have a bigger cubic capacity in engine terms, but it's not close to sheer German engineering of the Mercedes. The interior of CTS doesn't inspire and is short on space, the shoddy infotainment system is a big letdown.

Compare that to E class and you find the seamless integration and user-friendly features that are very easy to use, and the infotainment is a stunner, it's like 2 iPads joined together. In fuel economy department too, Mercedes is a clear winner thanks to its 9G-TRONIC.

Final Verdict

Overall, Mercedes E class does not have a fun factor plus it's more expensive than the rivals. However, it's super luxurious and really relaxing. The interior is a piece of art and needs to be seen and felt.

And with the new 3.0L V6 Bi-Turbo engine, it is capable of covering massive distance at a brisk and relaxed pace. So a typical luxury barge then? Yes.
