GLS63 not very AMG - Anyone Else Agree
I picked up a late 2021 GLS63 around 4 weeks ago and initial impressions are pretty much disappointment across several fronts, but mostly in the way it drives, sounds, feels etc. its just not quite full bore AMG like my X166 was in terms of feeling powerful, fast, loud etc. the X167 is very mute, lots of lag, feels like it needs more shove to get it going before it feels like that, and the exhaust pops and bangs are so tame Im almost struggling to hear it.
My 166 used to shake the windows in comparison. I know emissions regs and MHEV will have changed the way cars can sound but I believed MHEV was an aide to throttle response, it doesn’t feel like that.
The 48V roll bars are over sensitive, it doesn’t feel natural in this platform compared to others I’ve driven.
Build quality is poor, lots of niggly issues, faults etc which should not be present on a car at this price point, and for me it feels too “regular Mercedes@.
I had a Bentayga W12 last year and whilst not as nice to look at it did all of the things I mention much better, and it was a olde vehicle and wasn’t even their Speed model.
Im a long term AMG owner, mostly in the SUV line up and whilst the 167 is nice in some ways it’s not hiring the spot for me so far.
Anyone else felt the same with theirs?
Thanks




The stiffer chassis allows better suspensions, which in most cases feels softer, but provides significantly more grip.
The 166 had horrible grip on anything that wasn't smooooth, while the 166 just sticks like glue over railroad crossings mid-corner.
That, combined with active sway bars, give it the quick response you don't like. Also more ride improvement (and, simultaneously, sharper handling).
Did you drive one before you bought it?
Edit- You're in GB, so you're lucky you can even hear the exhaust!

It's kinda funny you post this, though. Sometime last year I dropped off my C63S coupe for service and somebody had dropped off a GLS 63 earlier. I was standing next to it when one of the staff had to move it. I was thinking to myself how very dull this car is. The way the engine starts up due to the mild hybrid system was so uneventful. I don't know if the GLS has Emotion Start, but in most newer AMGs you can press and hold one of the shift paddles while starting the engine for a more interesting startup. It mostly only does something during a warm start, but it blips the revs and the exhaust pops and crackles.
At the end of the day, the GLS is just a big and heavy lump. The ESP is never fully off in these, either, because they would flip over in the hands of a hooligan and AMG isn't gonna want that press coverage ever since the B Class failed the moose test, so they are never that exciting to drive. Personally, I don't get the appeal of these, but to each their own.

I went from a 2020 GLS580 to a 2024 GLS63 and the power difference was dramatic even in Comfort mode. But in Sports+ mode it is basically a supercar. There is also a button to open the exhaust and it is loud as hell.
I agree it’s powerful but isn’t responsively powerful, it has to be wound up, so the MHEV isn’t providing that instant power they’re meant to, and the exhaust whilst loud isnt AMG pop and bang theatre like it was in the 166, probably because of emissions regs and MHEV.
It just doesn’t feel dynamic, it isnt plush enough to be luxurious at the very pinnacle of luxury SUV ownership so it feels a bit undecided what it wants to be, and for me here in the UK the staggered tyre set up isn’t working, far too fidgety.
I expected this to be my best AMG by miles, but so far it’s my worst by miles.

I initially thought it was G Wagon withdrawal that made the GLS disappointing but it hasn’t improved and I’m clear why now.

Well you could always trade it in and take a little hit or maybe get a custom ECU tune.

At the track, my GLE 53, the plain old 6 cylinder, equipped with DPP / ARC, circulates with the S2000s and a little bit head of 944s. Leaves the WRX crowd in the dust.
There was an occasional W211 AMG55 that was in about the same grouping, but he seemed to be cautious.
It's not a GT3 Cup Car or a modded ZO6, but the GLE 53 AMG is rousing fun at the track. It's a great do-it-all vehicle, with compromises of course. But it tows my RV, hauls a lot of stuff, and is very responsive.
And yes, hooligan me has spun off the track and kept shiny side up.
I can turn off three levels of Nannies, so if there's intervention I don't think I've found it.
My GLE isn't that much smaller than a GLS, so I think the responsiveness would be there as well. If equipped for handling.

As for the intervention, the rollover protection is always active. You probably just didn't feel it as you had your hands full spinning out and you haven't pushed it enough yet to feel it on the track, but you'd likely be fading the brakes first if you took it to that level.

I agree it’s powerful, but it doesn’t feel responsive like the 166, that was like a rocket once you went for it, and sounded way nicer, “proper AMG”. The 167 takes too much to get started then the moment is gone, the 166 just went bang, gone.
Coupled with poor build quality, silly faults and a lack of luxury at the price point I just think the 167 version of the 63 is a let down. I know some things are better but so many are the same or worse than the 166 so this is not progress.
I actually thought about 4 new Michelin PS4 tyres as they were really great on my 166, and a Hunter alignment and roof force balance of said tyres to rule out alignment and tyre issues, because it just feels so unsettled but I doubt that’s the cause?
I guess the real question would be what expectations are out there on a full size, 3 row, SUV. In no way am I expecting performance similar to my 2017 AMG GTR or other AMG sedan/coupe/shooting brake.
I also don’t think comparison to the Bentayga is realistically possible…about 70-80k more expensive in ultra luxury range, and it’s also a smaller, 3 row SUV in terms of capacity with literally no space behind third row. Designed for different customer parameters to some extent. Took a 2023 for a test drive and loved it but did not fit what I was looking for.

What tyres (can't believe I just spelled it like I'm English) and size are on the vehicle? Wide tires are always going to tram with road imperfections, but mine is not overly bad for how wide they are, and it isn't a problem for me. I've got the 23 inch 4S tires, but my 22 inch winter setup, while mushier rides fine and handles pretty well also. I think at the very least you should check the alignment and tire pressures and at least confirm it's in spec.
At the end of the day, the 167 is faster and objectively handles better than the 166. But, drama/stiffness/noise always feels faster even if it isn't. It stinks that you are disappointed with your new purchase, but however much AMG "feel" there is or is not to you, the actually speed and handling of AMG is clearly there and better than what you had (although that doesn't make it a more enjoyable car necessarily). I'm very happy with mine, but I bought it years after I was last in an 166 63, so can't compare like you can.




FWIW My GLE weighs 5250# wet.
That's a whole other ballpark (over 300 lbs heavier than the 166 btw). I'm too lazy to compare the power to weight ratio between all the cars you mentioned, but you are probably pulling away from them on the straights, then losing some time in the corners, but not enough for them to catch you.
I pull away more in the corners than in the straights, but both. The S2000 was closest, corners and straights. You can definitely feel the AMG massaged AWD doing its job.
You can certainly strong arm an SUV around a track and make up time on the straights if you have the extra power, but at 5000 lbs you gonna chew up your tires and cook the brakes eventually if you are really getting on it.
(I finesse, not strongarm, but you're right the front tires were inadequate and the brakes fade.
As for the intervention, the rollover protection is always active. You probably just didn't feel it as you had your hands full spinning out
Actually my hands weren't full at all, it was just a normal spin out. My attention lapsed and I was paying attention to that ZO6 overtaking me. Amateur move on my part.
and you haven't pushed it enough yet to feel it on the track, but you'd likely be fading the brakes first if you took it to that level.

....
Certainly more capable than the 166.

I'm not suggesting it hasn't moved on as a vehicle, it has, no question, I just find it a bit too soft in C and fidgety in S on the motorway, but still with too much movement in the body, only S+ sorts that out but driving around in S+ all the time seems a bit much, the gearbox is a bit jumpy around town etc. for that.
Comparisons with 166, Bentayga etc. are still relative I feel, because those cars for me were 2016 vehicles, so older tech, but the improvements aren't there, the Bentayga did a better job of smoothing the ride to be super refined, then the thing could take off at will, the 167 GLS63 isn't really doing either of those as well, and thats current tech.
Im disappointed but yes maybe Im expecting too much, not sports car dynamics for sure, just more control, more planted feel as opposed to the feeling that its snaking around, and a bit more get up and go. The 167 is a lethargic large vehicle with lazy throttle unless you really push on, so feels every bit its size, which I really didn't expect, but just my initial thoughts on it.

I do play around with the settings to try and find the best mix for me, but none of that provides a settled ride quality and the more aggressive engine or gearbox settings can be a bit jerky, MHEV fanciness ey, MB should've stuck with good old V8 Bi Turbo




They probably accentuate Tramlining, and handling will be unpredictable at best.
Matched tires should help with the tramlining, and you can adjust the harshness with tire pressures.
I agree that the refinement of the 167 vs. the 166 masks its improvements. It's a more subtle performer, with the legendary German car characteristics of good ride and handling in the same package.

Mercedes tires also shows a performance 22" tire, Yokohama.
An advantage of MB sourced and installed tires is that there's a 2 year road hazard warranty included, not pro-rated.
I've found my Dealer is often cheaper than TireRack.

Interesting…when I go to Tire Rack for a 2024 with 22inch wheels I get several max performance summers to include PS4S and numerous P Zero all with the MO tags. Perhaps I got the model year wrong…
Negative on the litmus test for a ‘performance car’ since there are options for max performance affixed to this AMG SUV.
