- Mercedes-Benz C-Class: Why is My Suspension bouncy?
Guide to diagnose trouble and recommended solutions
Browse all: Steering and Suspension
Disappointed in this cars suspension qualities over rough roads.
The new cars all have cheap cast wheels. The 300E came with forged wheels that look like new. The new cars are so complicated, I can't work on them. My 300E never saw a dealer until she was 13 years old. My '04 E320 sounded like a cheap GM V6. The straight six in the 300E still runs as smooth as silk at 80 MPH.
My wife will get the new E550 and I'll just add another coat of Zaino to the best looking car that ever graced a parking lot.
I think the E Sport has decent handling for the intended market, demographic, and purpose of this car. The handling is not one of my "gripes". I think the issue of handling was discussed on this thread in context to ride quality - especially over rough stretches of pavement. I think one of the biggest challenges an automotive designer has is in balancing the need for a compliant ride over rough road surfaces, while continuing to provide inspired handling.
In this regards, I think the E Sport falls behind the class leaders in this segment in regards to quality ride - as does the E Luxury in regards to handling.
Getting this "mix" right is the subtle differene between an average and great car. Having said that, the definition of the perfect "mix" is as varied as the different expectations and desires of thousands of drivers.

Also, on a different point, isn't the Airmatic supposed to be able to provide great handling (sport mode) and great comfort (comfort mode)? If this isn't the case, as has been suggested by various E550 owners, there is something wrong with the set up that Benz needs to address. I for one wanted to add Airmatic to my next E-Class, but I certainly won't waste the money of there is no real comfort gain.

As KA stated earlier, given the mediocre handling of the E350 sedan, one shouldn't expect a really rough ride, also I do drive on sport mode 95% of the time and I don't think the car is overstressed on rough roads and on comfort more, do feel the car can get a little floatly.
Overall, very happy with the E550's combination of luxury, styling and performance

But stiffness is different than a "bottoming out" and/or "crashing" feeling. I have 2 Porsches (one with PASM and one with Bilstein PSS-10 coil overs) and while they are definitely "stiff' they go over rough roads with a secure and solid feeling. The E63 never "bottoms out"
Sounds like maybe they did some changes in Airmatic with the W212(?) It shouldn't feel sloppy or harsh at all. It should absorb the roughness in either setting with the stiffer setting being more solid and with less body roll in the twisties. The steering ratio in the E63 is different so you do get better feedback as it's more precise. That also makes it feel different I suppose. Plus it has thicker sway bars.
fwiw, the other day I drove up the Cabrillo Highway and headed into Jalama Ranch and to the Pacific Ocean. The trip was a mix of smooth and twisty roads; some rough ranch roads; and a narrow, twisty, bumpy last 10 miles to Jalama Beach. I realized how much I do appreciate the way the suspension behaves in different settings on different roads.
Tire type (not just size) can make a difference. Summer performance tires with stiffer sidewalls versus AS tires with softer sidewalls, etc.. Even between different brands....
This thread kind of reminds me of Goldilocks and the Three Bears. Or the Princess and the Pea.

Handling wise, I have no complaints with the W212, none at all. It handles great for my tastes, I even like the well engineered and controlled/tight subtle "float" that we get. However, of course, where it fails is how it handles harsh stuff.
I do think that even the Sport W212 leads the class in comfort over *smooth/decent roads*, but I'm not sure how it compares over rough roads. I do know that the new Audi A6 is supposed to be the noisiest and least dampening of the trio, as in order to meet it's very impressive weight goals, they did away with some sound deadening thickness, apparently.

My '06 E3504matic rear suspension seemed very uncoordinated with the chassis clumsy on bumpy roads and would feedback unseen disturbances through the steering.
An '08 E320 Bluetec that I drove later was much better in both regards.

But it shouldn't be unheard of to engineer an *E-Class*'s suspension to sit slightly low, and ride relatively firm, yet still absorb bumps and ride well when the going gets rough (yes I know, "Airmatic" is probably the cure, but you shouldn't have to go Air-Ride to get those qualities).
On smooth roads, this car rides brilliantly. Strong as an Ox, and has just enough "float" to keep things nice and smooth, but firm and tight as well, so you know it can handle some pushing, if need be. However, when the roads get bumpy and rough (and they do, in todays ravaged roads era), it rides like crap. Completely bumpy, lots of road chatter, lots of putting the structure to the test. It's unbefitting of an E-Class when you have to cringe when rough roads are on the way. My Chevy Malibu absorbs rough roads much better.
I'm under 30, and not too long ago, had a slammed Mustang GT with a 15" subwoofer and a no-muffler exhaust setup, so I can imagine that the general E demographic won't find this too kindly either. I think that MBUSA is shoving out the Sport Package as a free option to get the popping-smoke factor going, and gain sales, but I have a feeling that this may diminish Sales in the long run, as much of the E demographic will want something less fussy over rough patches, and something that won't bend rims so commonly, etc.
I will say, this is the #1 and virtually only thing that I am unhappy with about my car (aside from an annoying chatter/squeak at idle, which I need to get the Dealer to hopefully find and fix), enough so that it makes me question whether I'd want to keep it for the long haul (if I did buy it out after the Lease).
Note to M-B: The concept of a Sport suspension is to make a car handle like a Sports Car, which an E-Class appropriately doesn't do. Engineering a suspension TO RIDE HARSHLY ONLY FOR THE SAKE OF RIDING HARSHLY does *NOT* make a car "Sporty".
Sorry for the long post, had to rant!
Oh, and I will add: My AMG Sport Packaged W211 rode similar, but worse (the W212 keeps the same "Sport" concept, but improves it all around pretty well). The only thing the W212 does worse is I hear slightly more wheel-chatter when going over rough patches, but minimal.
I thought My Volvo S80 was nice and I still have it but whenever I drive it after driving the E550 I realize just just how good of a car the E550 is. The power, precision, and build quality compared to the Volvo is so much better with the E550. Even the click of the turn signal seems more solid with the E550. It definitely helps to have another car to appreciate some of what the Mercedes delivers.I have to say though that the ONLY aspect of the Volvo S80 I appreciate more than the Mercedes are the seats. The Volvo S80 seats are so much more comfortable and I especially like how the headrests are sloped to support your upper neck/lower head area.

couldn't agree more......my 2001 s40 has got amazing seats......very comfortable...

Hoping that the E350 Bluetec Luxury I plan to get at the year's end (if business goes well.... ::knock on wood:
recaptures some of that glory....
I think the W212 captures bears the soul of earlier 70's and 80's Benzes, I really felt that it had that classic Benz solidity (and the Design reminisces to them as well) and charm from the moment I got and drove it.
