CLS X218 complete Airmatic standard elevation

[Doncaster34]

Greetings everyone, could someone possessing a CLS X218 AMG Line equipped with the original 19” AMG wheels and complete AIRMATIC system provide a comparison of ride-height measurements with my vehicle?

My vehicle is a 2017 CLS 350d Shooting Brake, featuring the original staggered 19-inch configuration:

Front: 255/35 R19
Rear: 285/30 R19

Measured on a flat surface from the lower metallic edge (NOT from the base of the tire) of the alloy straight up to the wheel-arch lip:

Comfort: Front 670 mm, Rear 640 mm
Sport: Front 650 / 650 millimetres, Rear 630 / 630 millimetres

If anyone possesses an identical wheel/tyre configuration, could you kindly assess yours in Comfort and Sport utilising the same technique and share the four measurements? I am especially curious if the measurements of approximately 670 mm in the front and 640 mm in the rear in Comfort mode are standard for the X218.

I appreciate it!

If individuals were instructed to measure from the center of the wheels to the arch (which is the standard practice in the industry), the specific wheel and tyre combination would be irrelevant.

[Doncaster34]

I sincerely appreciate it. That is an excellent recommendation. It is logical for the purpose of comparison. I will request individuals to employ that technique instead, after I have obtained new measurements.

[Doncaster34]

Revision: I have now recalibrated using the superior centre-of-wheel-to-arch technique, ensuring that wheel/tyre dimensions do not influence the comparison.

In Airmatic Sport mode on a flat surface, I receive:
Front dimensions: 390 mm by 390 mm
Back: 370mm / 370mm

If someone possessing an X218 full AIRMATIC (front and rear) could measure from the center of the Mercedes emblem/wheel hub vertically to the wheel arch lip, it would be greatly appreciated. Optimal readings would be those of Comfort and Sport.

My husband possesses one of these, yet it lacks your Airmatic suspension and only features the air rear suspension. His vehicle resembles your photograph. Would his stature align with your comfort preferences? Inform me, and I shall contact him to retrieve the ruler...

That would be really useful, so thank you for that. While his front suspension won't be a direct comparison due to his standard steel setup instead of full AIRMATIC, his rear air suspension measurement would be highly helpful as it should sit at its normal self-leveling height, which is pretty close to my AIRMATIC in Comfort. Personally, I believe

Can he, preferably on level ground, take a vertical measurement from the center of the Mercedes star/wheel hub to the wheel-arch lip? I would greatly appreciate it if he could. Regardless of the front ends' suspension configuration, the rest of the car would be fascinating to look at. Much obliged.

Great thread!was correct when they suggested moving to the hub center method. Tire profile and pressure always cloud the rim-to-arch reading, so it's worth comparing your new numbers instead.

Your comfort to sport drop appears to be about correct for these vehicles, if that helps. In Sport, Airmatic lowers the front end by around 20 mm and the rear end by about 10 mm on the X218; these dimensions correspond to your 670 to 650 and 640 to 630 measurements, respectively. Therefore, nothing there shouts that something is amiss.

What would actually reassure me is that the two sides read the same, 670/670 and 640/640. When the level sensors show that the airmatic is at the desired height, the struts and accumulator are evenly holding the pressure, which is why symmetric readings are important. A worn strut or a leaking accumulator would have caused one corner to sit 15 or 20 mm lower than the other. Put your worries about it drooping to rest; it appears to be level on yours.

A few things to keep in mind so that other people's measurements are fair. No one else in the car, same tyre pressures, about the same amount of gas and on a flat, level surface. The readings obtained after a run and those taken after parking for some time might be slightly different because Airmatic adjusts the ride height depending on the vehicle's position.

Even with the steel front, Cherrypd, your husband's rear air figure will serve as a good stand-in for the OP's Comfort rear, as both rears will self-level to their respective targets. True to what the OP stated, fronts will clash.
