So isn't this same as the EDC in ZCP that is using the viscosity fluid? They just labeled it different?

BMW does not use Magneride, which I think it was you're referring to. (It uses a a fluid that changes viscosity when a magnetic field is applied). That is made by Delphi (now owned by BWI).

Depending on the model, BMW uses Tenneco, Sachs, and Bilstein as suppliers for their adaptive suspensions. All three systems use an electric solenoid inside the shock to vary the damping in real time. The end result is similar to Magneride (continuously variable damping), but they work differently internally.

Tenneco is on the F30 and F22, Sachs is on the E9X M3, and I'm not sure which system is on the F8X. or other vehicles.

I see what you are saying but I think my point was, in theory, it is pretty much the same thing. The EDC in the current M3 was the "static" version where pre-determined suspension stiffness was applied in sport, normal, and comfort. With ZDC/competition package, they had variable control, which is what this adaptive M suspension is. It's pretty much the same technology, but branded differently, correct?

The current M3 was variable control is normal and comfort and static in sport. The competition package is variable in sport as well. I would expect that the F8o has variable damping in all of its modes.

From the basic standpoint of functionality, you could consider all the various systems out there to be pretty similar. However, the hardware, software, actual performance capabilities and tuning methods are actually quite different. So different systems allow the engineers to achieve different results. The system on the F30 would not perform well on the F80, and the system on the F80 is likely too expensive for the F30.

Read the the thread I linked to earlier in this thread.

Hmmmm! I don't remember the Sport mode being variable on the ZCP equipped M3's.

Everything I've read says that it is, including comments from BMW engineers.

I know that the EDC's Sport mode was reprogrammed, but I don't remember it being variable. Ah well! I didn't spend much time in Sport anyway.

What Racer20 is correct, as I also posted in post #10 in this thread. EDC is dynamic in Comfort and Sport modes and static in Sport on standard M3s. All 3 modes are dynamic on Competition Package (ZCP) cars.

Ah okay! A little tidbit that I overlooked in my E9X days.

So then if i n driving a zcp car this adaptive m suspension is exactly what i have.

Well, probably close, but that's like saying Ohlins and Bilstein and KW are all coil-overs, so they're all the same. They all serve the same function, but they aren't really the same.

I'd expect the M3/4 adaptive suspension to perform very well. This type of technology has advanced quite a bit in the past few years.

I would definetly not say "exactly the same". Similar in concept maybe. We are talking 7 years of evolution here.

[iPhone vs Android]

Yes, I meant similar in concept and you are right it has probably improved, but I'd say more so 2-3 years of evolution not 7 as the reprogrammed EDC in ZCP was available first in 2011. I also hardly think they wrote everything from scratch in the new car as far as EDC software goes.

It it is not only in the code. The hardware makes a significant difference too. The EDC hardware on the E9X has been the same since launch in 2007. So it is 7 years of evolution...

Exactly!

If the adaptive changes the dampening in different modes, what will the car be setup as with the standard suspension?

Read the thread.

EDC is a great option. It allows you to have a comfortable setting for the DD and a more aggressive setting for a romp in the twisties. I run a stock suspension and EDC on Sport (or Normal on bumpy tracks) and it is perfectly suitable for track use even with R compounds.

I always found my E46 M3 do be too stiff for the DD and too soft at the track. EDC on my E92 provides the best of both worlds. So, to answer your question, a car without EDC is a compromised setup and will not equate what EDC can provide, since EDC is dynamically adaptive, the standard shocks will not equate to any of the 3 settings.

The ///M cars do not come with variable ratio steering, but they do come with variable assist.

I enjoyed the 3 settings on my M3, but the incoming M4 launch car I can get for a deal lacks the adaptive pkg. Trying to decide if it's worth foregoing for the discount? Just hope the ride isn't too rough for cruising, I did enjoy the mode choice option.

I'd take the discount.

Thx, I'm leaning that way.

Update:
"BMW genius" left me a voicemail saying based on their research only M-Adaptive electronically monitors the road. Does this sound like a feature definitely worth pursuing? Or do you think it's a bit superfluous?
Thx! Just a little worried if I want to sell prior to lease end, fewer may be wanting this car without M-Adaptive suspension?

I like it, but I don't think it has a big effect on resale, though I have no data to support that.

There are many an E9X out there without EDC. You can live without M-Adaptive.
