Air Suspension no longer lowers at highway speeds (FW update v5.8)

[Lump]

An owner on Facebook claims Air Suspension was disabled at high speeds (he got 5.8).

I have not seen this... must be a one-off.

Confirmed 5.8 does not lower car at speeds > 60mph

Huzzah. Tesla heard our concerns. Let's see if the Wh/mile numbers worsen slightly (always tough to ascribe any change to one particular reason though).

The lowering at highway speeds was originally done after a delay. How long did you wait after reaching the 60mph, to decide that lowering was no longer performed?

So when does it lower then? Never? Does it lower when we manually request to lower above 60?

i prefer the car lowering as it gives it a more sleek look on the road

Would be better if that was optional.

10 miles.

yes. should be an option/checkbox/slider switch.

i would still like it to auto lower at highway speeds, unless i manually lock it out (say if i'm on a debris filled road.. lol).

can it be manually lowered once at highway speed and stay there, until low speed threshold crossed?

i have 5.8 but haven't tested that yet....

wow. This is great they are making this change!!

i agree with above comments

 

[vgrinshpun]

Which makes you wonder where all that capacity was when they did the slow roll-outs before....

I am wondering if removing default lowering of the car at highway speeds is the main reason 5.8 is being deployed at unusually high speed. Could it be that the promised Elon's post in response to the third fire incident is going to be posted tomorrow, and will mention the delete of default setting.

I really hope, though, that I will be able to turn this feature back on - like reduced power consumption and improved high speed stability!

For the record, I didn't start this thread, I guess Nigel did. I was only passing along a tidbit from Facebook that I found kind of odd that nothing was mentioned in the release notes but 1 owner was making. If its true maybe Elon will address it in his blog.

 

[FlasherZ]

The original behavior was to lower the car at 74 mph instantly, or if > 55 mph for more than 15 seconds.

Agree 100%

There's always the option not to install v5.8.

Correct. At least bhuwan has tried it out and confirmed and I'm guessing that it's related to the couple of road accidents when folks drove over stuff. I'll come back and change the title if this all turns out to be coincidence.

Blame this one on me, not Nigel. I requested he pull out a separate thread for this discussion. I hope you don't mind.

Reference? Or is this empirical data? Thanks.

I don't recall the source but Flasher is correct. Hmmm, now I think about it IIRC I was told that by my DS on delivery day.

Not if 5.6 screws my Bluetooth and I was told that 5.8 suppose to fix this known bug...

IMO Tesla has decided to make this change to work out the situation with NHTSA. I think that for the time being it will work. It's a change that can be done via firmware and is almost costless. I am sure that in the future Tesla will make some structural changes to the Model S that will improve also the performance and handling of the Model S allowing again the air suspension to lower at high speeds.
