2025 GLS450 Ride Quality
have a 26 loaner, MUCH MUCH MUCH smoother ride
has suspension been tuned differently for 26? is there Airmatic firmware that could be the culprit for me?
it's maddening..compared to bmws (x5, x7, i7) and cadillac (escalade esv sport plat) absolutely trash ride.. harsh over bumps beyond believe, lateral grip when going over rough surfaces in curves poor but i can live with. feeling bumps in my bones pisses me off for 105+

Does the 26 have different tire combo? Did you match the PSI on both cars? Maybe the tires?
As for your comment about the GLS vs X5/X7/i7, I had ALL these cars as well as the GLS. Do not expect the GLS to be as good as the i7 (it’s not fair to make that comparison), but it should be as comfy as the X7 without DHP and much much more comfy than the X5. X7 with DHP and small wheel sizes is slightly more confident on the road.

re tires, PSI same all around mine vs loaner...21" AMG all season setup on both (RWH 5 SPOKE)..tires: one has Michelin Primacy, the other Pirellis
big question is : how to remedy? transmission being rough then maybe software and coding outdated...but what about rough ride? could same be true for Airmatic software?

wish i had a better handle on what gear shifts are most problematic so i can point them in right direction. think 1 to 2 in any mode (comfort, etc) is most problematic.
i was told, not sure if accurate, that software is different on 26 for both airmatic and transmission vs the 25..will keep you posted, great dealership i work with so they are taking concern seriously

If I were buying a vehicle as a family vehicle, I would get the GLS for the better size. I also like the looks of it more inside and out. If I was getting a car for me to drive every day though I would get the X7 for the better ride and drive.
Very interested about there being a possible software update to Airmatic- would be killer for someone to help verify that or post some documentation if they've got any software update already. If I find myself at the dealership, I'll inquire and find out as much as I can.

I don’t know about Sport and Sport+ drive modes, but I feel that car is more comfortable to drive in Comfort mode for sure, but it is less bouncy in Sport mode. It depends on where you live and type of roads. If the roads are perfect around you, Sport mode is the best perhaps.

The GLS is the perfect SUV for road trips… 550 miles of highway range in eco mode, smooth 450 drivetrain, and great comfortable 2nd and 3rd row. We’re currently debating between the X7, GLS, and a few other EV SUV options as the next replacement for the GLS in the near future. Rivian is awesome but has the same versatility limitations as the X7. Gravity is flawless and we don’t mind the van-sh look. But given the perfect size and versatility of the GLS as a family hauler, it’s really difficult to risk anything else.. it gets 10/10 especially given it’s price for the 450. Loaded X7 40i to our liking is 125K. Loaded GLS 450 to our liking is 100K. Mbenz with standard speakers, Airmatic and standard AMG wheels are more than enough. BMW with anything less than B&W speakers, DHP suspension package and upgraded wheels is not a car we’d ever consider, and those together adds nearly 10K.
If I were buying a car for myself, I would choose the X7 M60 once again. I very much enjoyed my former X7 M50 and X7 M60…they were among the finest and most exceptional daily drivers I had ever owned.
