- Mercedes-Benz C-Class: Why is My Suspension bouncy?

Disappointed in this cars suspension qualities over rough roads.
FWIW, I test drove a 2010 E350 coupe (yes I know it's really a modified C Class chassis in disguise) and was shocked at how poorly it rode with the sport package with 18" wheels and stiffer suspension, compared to one I drove subsequently without that package.
No question, the coupe and sedan look better with the sport package, but for some of us there comes a time in life when one's kidneys tend to take precedence over one's eye appeal. Sigh. Will be ordering a 2012 without the sport package.
BTW, those of you driving the 2010-11 E Sedan, IMO it's the best looking sedan on the road in that class. Congrats.

I also had a late build 2009 W211 E350 and although it was okay on the freeway and on smooth roads like the PCH, etc., it was really pretty poor on most roads. I don't mind the suspension in the C Class but I think it's because it's a lighter chassis and shorter wheelbase. The steel suspension as it's designed in the E Class chassis just doesn't seem to work.
Airmatic is definitely a way much better ride (even with the stiffer AMG version.) ABC is pretty amazing and keeps the car basically flat in the twisties. But the weight of the S Class is a bit too much to really feel that nimble....
The W212 Sport has maybe the best ride I've ever experienced over good, and even decent roads, but over bad roads, it's a disaster, for what you'd expect.
And I agree with the comments about its looks!
Second to none there to me right now.
I've heard the facelift W204 has enough of a better suspension tuning, that it makes the cars frame actually feel stiffer (which isn't the case, as M-B of course didn't touch the frame or chassis). Interesting to wonder whether the new suspension tuning brings it up to par with the W212's, or if it is something the W212 can also use to smooth things out.
No argument. I totally agree with you. Since we are posting in the E Sedan forum, I wished to point out that I knew the coupe was not the same chassis as the sedan.
My quibble is not with the coupe riding on a C chassis. Rather, it's with MB's sport suspension package which, from reading this thread, apparently produces similar ride quality differences in the sedan (which I have not driven) as in the coupe.
BTW, have enjoyed reading many of your informative posts, along with those of other helpful regulars, while lurking in these forums before joining.

Thank you for your kind comments. I think I love your term "quibbles". Speaking strictly for my E350 BlueTEC, it is so solid that I think "quibble" fits better than "problem". I learn a lot from many of the fine folks here. It is a very well done forum.

I will say that I loved the solid feel of my W204 C300 sport's chassis with the 18" wheels as I do believe the 18" wheels improve handling over the 17's. But I'm sure we are less critical on the C as we expect more from the E. I do believe the airmatic suspension would be the answer for you. I chose the E550 for 2 reasons, the engine and the airmatic (as probably everyother E550 buyer since those are basically the main differences between the 350 and 550) with the 2 being equally important. I also wish there was a sport+ setting as I feel my C300 was a more solid and better handling car but I guess that's what the E63 is for. I basically keep my setting on sport and then switch to comfort are particularly bad roads on my commute in LA. Also love the slightly lowered look with the sport setting.
I think the sweet spot E for daily driving would be the E350 Sport with the new 306HP engine with the airmatic suspension.




Glad to see CR has kinder things to say about "E" class now. Can I assume that the 2010 Sedan and 2011 Blue Tech have the same suspension?
The Best of Mercedes & AMG
The W212 is a modified chassis that first appeared on the W204 C-Class. It's modified in size, and I'm sure they stiffened it up some to support the extra dimensions.
However, performance isn't high on my list of "wants" on this car. My main cares with a car like this are: Style, Safety, Comfort, and interior quality/design/comfort.
I have driven a non-Sport '04 W211 E320 and the thing was anything but intriguing or great to drive. Comfy yes, but it floated immensely (almost to the point of not feeling so safe), and was noticeably underpowered. The M272 E350 motor has a fine amount of power for me, and I do love the firm/float/tight mix that the Sport W212 has over good and decent roads, but if it just absorbed roughness better it could literally have the "worlds best ride" to me.
The Sport W212 still has the best comfort oriented ride in its Class, when comparing against other Sport models, but it being an M-B, it should go that extra mile and handle the harsher elements as well.

And that is why I can't wait to get back into another BMW. The BMW's that I have owned in the past, including the E60, seem to have the perfect combination of sportiness with forgiving ride over rough roads. There is not a day that goes by that I don't wish I was still driving that car.
I am more disappointed in my 2011 E350 than any car I have ever owned in the past 30 years.
The ride is poor over anything less than smooth roads. The acceleration is anemic. The 268HP engine lags behind the competition. The fuel economy is subpar. At $56,775 MSRP I got crappy plastic (MB-Tek) seats, no heated steering wheel, and underperforming headlamps (no bi-xenon). The electronics including the NAV seems a generation behind in technology and useful features. You can't order anything close to an audiophile quality sound system. The trunk has no pass-thru for skis. The interior is ho-hum with a lot of average grade materials. And to top it off, reliability has been poor in my experience with ECU issues.
The only good news is that my 24 month lease expires in 18 months and I can order a proper MB or select from several other attractive automotive options.
If I remember correctly, you were never really taken back by the W212, or never really seemed interested in it (wanted an F10), but only bought it because of MBUSA's ridiculous incentives/price cuts, correct?
Tsk tsk.

I on the other hand am very happy with this car, and every time I park it next to an F10, or almost anything, I am assured by it. The HP isn't much of an issue with me, but it is kind of upsetting due to the fact that on other hand MPG's aren't through the roof. I found the E60 I used to drive to be MUCH harsher than the E, but maybe comparative on rough roads (can't get much worse than the E Sport, to be honest). I also found the F10 Sport to have a less soothing drive, as it bounced a bit more on regular roads, and had a less than refined stop-go relationship, due to the turbo lag and/or throttle response and/or transmission. On the other hand, the 535i motor has more pep and power when you push it (not so noticeable when you're just cruising), but it comes at a couple costs: Non-smooth normal City operation, and some reliability issues with that motor (unless they've fixed it).
The E is a calmer car and environment, but it f***'s everything up when the roads turn to crap.

I agree man, it is a bumpy ride in both modes........it's interesting to hear about the the smaller tires even not making much difference.....I too am disappointed in this regard...
but it is crisp on smooth roads huh? 550!!!!
I do agree that comfort mode on airmatic is not a 180 compared to the sport mode and do wish for a greater difference between the settings but the roads in L.A. are decent most of the time, potholes get fixed fairly quickly and freeways are pretty smooth. That's we pay higher gas prices.

But on the plus side you have a significantly better engine than the anemic 268HP E350. Plus you don't have to sit on plastic seats, or suffer during night driving without the bi-xenon lights on the P1 E350 versions.

Good "road feel" generally describes solid handling where the driver can get feedback from the tires, suspension and steering wheel. This is especially important as you approach the limits of the car. It does NOT mean that when you run over a coin on the road that you can tell whether it as a dime or a quarter.
A great suspension is extremely difficult thing to design - in part because every driver has a different set of expectations. Most cars feel great on smooth roads, however, a well designed suspension has the ability to competently handle rough patches of pavement without the need to A) "float" over the road, or B "jar" you until your fillings fall out of your teeth and your kidneys are sore.
If you have driven enough cars from Porches to Lexuses you generally get a feeling for what works for you.
Unfortunately the E350 is jarring over rough roads.
