M235i uses the adjustable damping, M2 doesnt. Would appreciate someone explaining for me as to how they achieve this.

[ilovewagons]

I don't know for sure, but having sampled BMWs adjustable damping, I think that what they did with the M2 was actually do some hard work in calculating spring rates, rebound, etc. to start off with a great suspension set up. I find that adjustable suspension is a lazy cheat. You get to choose between brittle non-compliance (which is great for the mirror smooth racetracks you never drive on) or wallowy, floaty disconnect, which is awful as soon as you try and turn the car. It lets them get away with a half-assed suspension set-up because you have different 'modes' that work in a handful of conditions but the underlying setup just isn't quite right.

Same way as with the 1M: testing with different set-ups and in the end selecting a compromise set-up, considering that most will use the car on urban roads and sometimes on a track.

A BMW M engineer said in an interview that he preferred the static suspension on the M4 as the adaptive is the compromise as one spring has to handle a lot of things.

This.

I had adaptive suspension on my ex E90 M3. Useless/ I never used it...

Same on my old e92. Absolutely useless.

Only advantage was the competition package being 10mm lower.

I believe the adaptive suspension on the F80/82 is different. It is actually adaptive in real time to adjust to road conditions. The E9X was a soft/medium/firm system... on/off kind of. The current adaptive suspension allows the suspension to adjust more dynamically and M4's, for example, with it are putting up better lap times than the standard suspension. The magnetic suspension used by GM and Ferrari is another (although much better) example of this and it is fantastic.

On the E92, I agree it was not particularly useful. On the F82, I have a different view.

I've had magnetic suspension before and agree it was much better. I think I would prefer Coilovers anyway for the M2

The engineer still preferred the static suspension.

I think it's a cost issue. Adaptive magnetic damping is the future. I see the benefit of an adjustable coil over setup being weight savings, and durability. Neither of which will be noticed by most owners.

There's no such thing as a double duty car. It's a compromise plain and simple. Show me car that rides like a Lexus LS and turns lap times like it's GT counterpart???

I had a DD that I took to the track. The more I modified to increase track satisfaction, the less fun it was to drive on the street. That was with custom valved dampers to match the springs, suspension travel, etc.

Comfy on the street means lighter springs, increased grip meant I was on the bumps tops on the track. Heavier springs on track........round and round it goes.

Understood... I read the same thing

That's a subjective view though... the OBJECTIVE testing suggests the adaptive suspension results in faster lap times. I have a passive suspension on my M4 and it's great. I have also experienced the adaptive and also feel it is more stable and felt more planted.

The M2 is more firm to me than my E92 in its most firm setting. However, the M2 is more of a tight rebound whereas the M3 can be crashy or thrashy firm. You can really hear the suspension working in the M2.

[ClothSeats]

The old-fashioned way. I like static systems as they are more predictable and don't overheat.

The suspension is more rigid indeed, especially on bad roads.

With the radio of (lousy sound so it doesn`t matter) you can hear the side window closing on and on (like the automatic window closing function when you shut the door), it does look like the cars chassis isn`t that stiff.

have you ever driven a car with bmw adaptive? coming from a Zl1 with magnetic i prefer the adaptive.

Yeah my e92 m3 competition

[BMWPWR]

And I've driven an M4 with it.

the suspension on the e92 is nothing like the modern dynamic dampening.
