For those that have the option of Sport +, do you also have an additional display apart from the Classic, Sport, Progressive and Understated display?

 

Not that I've noticed, no

 

Thanks! I thought you may get that single rpm dial display. I guess its only for the l "AMG" ie. GLE53

 

Correct.

 

What vehicles have the Sport+ option? I have a 450 with the AMG package and airmatic, but I only have Offroad, Eco, Comform, Sport, and Individual.

 

So far, you need E-ABC to get this. The future GLE 53 & 63 will have it. Not sure about the 580.

 

No

 

On sport plus the suspension goes to -2, the suspension is notably stiffer and the transmission holds the gears significantly longer, curve mode is, as expected, also active. In sport it goes to -1 and the other changes are milder.

 

Curve mode is independent of Sport+. In Curve mode the suspension is at its normal height; it is not intended as a sporty setting, but more for comfort. Road Scan is active in Curve but not in Sport or Sport+.

 

by curve mode I mean the curve leveling function. You are correct in CV its at comfort 0 level.

 

Well, it's not curve leveling, per se; the roll resistance is just increased like having stiffer antiroll bars.

 

in effect it is. As far as I know only the 63 has the active roll bars (like our previous 550) with eabc the electric portion of the struts counteracts the body roll in the CV and sport modes. The 63 doesn't have EABC thus the need for the roll bars.

 

E-ABC and an AMG53 with AMG Ride Control (ARC) both have active roll bars. I assume (?) that the 63 is the same.

E-ABC leans into the curve, based on your selection of 1,2, or 3 - levels of tilt. It's a comfort setting.
The ARC doesn't lean INTO, but is designed to stay flat. It's a performance setting.

These systems are vastly different from previous versions, on various M-B models, some with the exact same name.

 

We're off the original topic, which was Sport+ instrument panel displays! However, sorry, but E-ABC does not use active roll bars. Control of each wheel is by electrohydraulic actuation of each damper assembly and there are no antiroll bars involved. The names of these systems have been similar in the past. Active Ride Control is an update of the Active Curve I had on my '12 ML (ahead of it's time). Active Body Control has been used in other models, but not with the "E" prefix.

 

From the owners manual:
Drive program sport +:
The suspension setting is even firmer.
The vehicle is set to Sport + level.
ROROADSUFACE SCAN is deactivated.
The curve inclination function is active.

In sport mode both the inclination program and road scan are off. Road scan, the magic carpet part of the system, is only on in comfort and CV (curve) mode.

 

Funny, I was roundly criticized when I posted those same references last summer. They must have gained credibility over time. My bad for trusting feedback from....
I admit I can be fooled by Daimler press releases, especially regarding their propensity for using the same name for different products. BTW they show E-ABC on some Coupe versions 2017-2019, just to confound things further. Belt-driven hydraulic pumps instead of direct motor-driven, as I recall.

Are you sure that there are no sway bars on E-ABC cars? Can you provide a source?
That would explain the dramatically different feel I have from my former E-ABC and my current ARC. I was hoping the ARC would fix the shortfalls of E-ABC, but it just introduces another form of instability. I think both have potential, but not ready for Prime Time yet.

I hope the OP doesn't mind if an evolving discussion of suspensions enters the thread, which began on post #5. These things happen.

 

Correct sway bars are not needed since the electrical component does the job and does it better! Swaybars are a reactive system while EABC is an active system. I was surprised that AMG didn't include it in the 63. Maybe its not "track ready".

 

Sway bars, even active ones, would be redundant, since the active dampers at each wheel can provide full control.

Here is the system in the S-Class, which is almost the same.

I recall reading that E-ABC was omitted from the 63 due to weight considerations. I can't find a link however.

 

Early Daimler press releases indicated that the AMG Ride Control used a predictive system to adjust the active sway bars. The releases seem to imply cameras are involved. Several of us on the forum have tried to discover what actually drives the active bars on the ARC. Or what the ARC is really doing.

Trying to judge from the "feel" of the ARC, it seems to soften bumps better than E-ABC, and do it only on the side needed. The E-ABC seems to see the road ahead (sometimes) but adjusts (relaxes) both sides equally. Comparative result - E-ABC is good on speed bumps and railroad crossings, but not potholes affecting one side. ARC adjusts for that pothole, but I don't know how.
The ride is certainly better with ARC than standard AMG53 Air, and I wish I knew the mechanism.
Audi and Porsche use active sway bars, options that cost about the same as the AMG Dynamic Plus Package on the 53. Are they different?

 

It looks like the Active Sway Bars on AMG Ride Control ('21 AMG 53) are still a mystery, regarding what drives them.

Heading out for the 500th mile on our new one today. Tires should be broken in.
Continental Tires seem to be the weak link in NVH and cornering so far. Adjusting to the gas flap recommendations of 41F, 35R for this trip. Seems an odd recommendation but we'll see.
81F here in the foothills. Should be a nice drive. Plenty of twisties and high speed, good visibility corners ahead.

 

That’s the pressure for Highway tires...don’t you have AS’s?
AS Conti tires are M&S rated see the sidewall. 38/33 or 46/45.

 

I am not a fan of M+S "ratings" on tires, so I thought I'd air down from the 45/45 that the car was delivered with, to the next step down, which is <blank> pressure of 41/35 (top line on gas flap). (It's easier to air down than fire up the compressor to air up, so I took the easy way to see what it felt like, to adjust later.)
To digress, M+S is not a "rating" or performance attainment - it's just an advertising "claim." The Three Peaks Mountain Snowflake (3PMSF) is an actual performance rating. At least in the USA.
The Conti's are marked M+S, but they don't qualify for the 3PMSF, so I used the NON-3PMSF pressures. (My rationale FWIW.)
Also, the OE Conti's are marked MO-1, which means that the tires are developed for AMG cars - "Mercedes Original 1- Made specifically for AMG, MO1 tires have a rubber mixture and carcass structure that match the vehicle’s suspension." https://www.mbusa.com/en/owners/part...original-tires

We're still in break-in mode, started at 420 miles and added 140 miles round trip, gaining 2,600' in elevation, on one of my favorite local drives. Pavement from rough chip-seal to new asphalt, low traffic, great views, lots of 40 mph curves and more 90mph sweepers. Since it's breaking in, I tried to use no more than half throttle and only exceeded 85 a couple of times.

The outbound leg was pretty Ho Hum. Ride was fine on Comfort to Sport+ but the tires / suspension just didn't give much confidence. I was pleased with the ride but really disappointed with the handling. This is a AMG Ride Control car (AMG Dynamic Package). But the car still felt really heavy and stodgy, even on Sport+. Was it the tires, or just a heavy car that feels Really Heavy?

So for the return leg, I dove into the MBUX menu and changed the Individual Setting to options that I don't really understand, just to see, and headed back.
WOW What a Difference! The car came alive. The front tires had predictable grip, the car was eager for curves, and I even think the AMG 4Matic+ was adjusting for understeer/oversteer. And even though I had the exhaust set on "Balanced," there was more rev-matching than in Sport+, and more barks and burbles on overrun.
You can see the settings I made in the AMG Drive Select menus at the right of the pic below. I don't think "Dynamic" engine and "Advanced" settings are available without the AMG Dynamic Package.

I'll post some more on the settings in the @Ron.s thread 2021 GLE53 Driving Impressions vs GLE450 and add the link here later.

I am impressed - it's a new era of fun and comfort that I had hoped for but thought wasn't available any more. It's nimble!
And my Wife doesn't grab the handles as I approach that 40mph-marked corner at 65 - it's that confidence inspiring. (as long as I can see there's no deer about to jump out)

 

To me the AMG line looks better. The question is, what options will be there for 2022? The AMG line at the moment (2021) does not come with the AMG steering wheel. The basic steering wheel looks boring to me while the AMG looks like a piece of art. Very subjective of course.
