when using sport/sport+ i know the suspension is stiffer but is it both front and rear that gets stiffer or only the rear? I ask because i know only the rear is air ride and the front is spring/shock. This would help me make a decision on wether to lower or not. thanks in advance.

I think sport and sport plus is just for the trans shifting. The suspension firmness is the other buttons that have the shocks absorber logo on them. You can put it on either 1 led light or 2, 2 being the firmest setting.

Only the rear is affected with that suspension button I think

vdubpower

all 4 corners

vcci

Yes I meant sport/+ in suspension mode not transmission.

Has this been confirmed?

It definitely feels like all 4 corners firm up while in sport/+(2 led's lit)

AFAIK front is not affected by suspension settings... It lowers and stiffens the rear only. I would love to be proven wrong

otakki

I think the suspension settings affect only the rear as well.

HPMan

My understanding is that only the rear suspension's ride height is altered by changing the suspension modes but that the dampening on all 4 corners is altered. Does anybody know if there is an electrical connection on the front struts for the car's control system to adjust dampening?

PeterUbers

Here in may lie the real answer

vcci

Makes sense, can anyone confirm this?

vdubpower

damping affected to all 4 corners, height adjustment dependent on load and speed of car driven

This ^

It wouldn't make sense to lower the rear and not the front. The car maintains a nice steady height on the rear according to the little link thing and the damping firms up all over.

I love how this car handles...what an achievement for something that weighs 2 damn tonnes!

TheOtherEric

Well it may not make sense, but that's exactly what the car does. It's all described in the owners manual -- the rear lowers itself almost an inch when set to sport suspension or after you've shut the car off for a few minutes. No ride height changes up front.

Celicasaur

I'm going to try that on my car and see if that happens. It would be bizarre if Mercedes deemed that a smart thing to do...mind you, even if the theory is wrong, whatever it does, the car handles brilliantly after that, haha

If the front stiffness isn't adjustable, can someone explain the quick noise I get from both the front and rear suspension when I go over the speed bumps in the office parking garage that I could swear was air being released to take some of the byte out of the bumps.
I agree that the owners manual refers only to rear height adjustment.

vcci

I've been aware of only the rear adjusting height since before i bought the car, its the firmness that i'm still not sure about.

I would definitely take the magnetic ride suspension like Cadillac has over the air bags. The car would ride better and probably handle a little better. Oh well, can't have everything, everything else about the car I like. That was about the only thing I liked better in the CTS-V Wagon I had before the AMG Wagon. I really wish on the 2017's they'd get rid of the Air bags and go Magnetic Suspension but I don't think that is in the plans.

MRC will definitely allow the car to handle and ride better. The latest generation's changing speed from full firm to full soft is just mind boggling. I doubt MB is going to have it. It's too bad MB don't have the "can't beat them, join them" mentality. Look at Audi and Ferrari, both of them pay GM's patent and hopped into MRC.

I personally cannot tell the difference between Sport or Sport+ suspension settings on my car. To me the car handles like garbage with speeds over 100-120+. Feels like a boat that's top heavy and often sways when maneuvering lanes. I've taken it in to the dealership to have them look at it and they deem it normal.

otakki

Even more so if you have pano.

AMGJAY

Yep, pano just makes it even more top heavy.

PeterUbers

Anytime I complain about a problem at 100+ mph the dealer refuses to get the car up that fast to assess

AMGJAY

Same. I think they don't exceed like 75mph.

I told them that I'd gladly take one of their techs on the upside of 170. They just need to provide the workmans comp for their tech. Lol

The tendency for this car to roll is noticeable between sport and sport+. I am in the "all-4-corners" camp, if the front of the car wasn't adjustable then the rear would step out more or at least roll less than the front...

MRC is kind of god tier, unfair comparison to AirMatic

evansw220

All 4 corner shocks are equipped with dampening solenoids,the rear Air Bags are for load and also lowers when in Suspension Sport setting or when the car turned off.... If you get a chance turn your wheels you'll see the solenoids mounted to the front shocks...
