First Dream Edition Delivery!

[Joe]

Yes, please let’s keep this thread focused on the first Gravity DE delivery and the questions that @Osyris is kindly taking the time to answer.

 

[DeaneG]

Does anyone beside Tesla use 400v DCFCs?

Only Tesla. There were some 50kW 450V CCS stations years ago, which is why the Air was originally designed to upconvert from 450V at only 50kW - it was enough.
CCS has been standardized at 1000V for a long time.

I like the low look, feel free to discuss.

Love it! But what is the camber and toe in the low ride height setting with factory alignment?
One thing I was thinking about is that the independent rear steer could allow the car to automatically keep toe at zero for max efficiency and minimum tire wear. Would be cool to have that ability in the front too.

Seriously…took like a year to figure out the bolt pattern!

Something wicked this way comes.

haha.
Ok, what is the clearance between the caliper and the barrel? Any chance of fitting 18" wheels?

 

[ChestRockwell]

Are the bear decals only on DEs?

It is my understanding that the titanium bears are only on the DEs but you can choose to have regular bears put on any Lucid car (or not) at delivery.

 

[Leftlane]

That looks so good!

Hi there! Quick question: How is the built quality? Is there any rattling or squeaking? I know the car is extremely quiet, so I am wondering if the quietness amplifies internal noises. Thanks! Congratulations again!

I'd be really surprised if Lucid didn't cover that base with their focus on efficiency and range.

High chance 19s won’t fit with 6 piston Brembo up front.

 

[Elfin]

Obviously it's easy to change toe with ride height but I'm wondering if there's a way for car to measure the actual toe. An auto-aligning car would be great.

Yeah, seems very unlikely 18s will fit. Though somehow they claim to have tested with BFG KO2 all terrain tires and those aren't even available in 19" and all of the 20" versions have larger than stock outer diameter.
I swear these look smaller than 20":

 

[flarbear]

The NA in NACS is North American. Cars in most of the rest of the world, including Teslas, use CCS2. It's my understanding that CCS2 has been supporting higher voltages all along unlike the Supercharger network...?

The tires aren’t even same diameter front to back, and aren’t the same width 20 vs 22 and 21 vs 23 (8.6 vs 10” for the rear small to biggest).

It’s a number mess…swapping tires is gonna need a menu selector…

 

[hmp10]

Obviously it's easy to change toe with ride height but I'm wondering if there's a way for car to measure the actual toe. An auto-aligning car would be great.

Wouldn't the rear steering actuators have position sensors so they could deflect the wheels to the angles dictated by the computer algorithm? And wouldn't there be a reference point from which the actuators deflect that could be set at the zero toe point for each suspension height?

 

[Pragmatic]

Is the rear steer independent left to right? Most (all?), systems I know of, the left and right side wheels are connected to a single rack (one for front another for rear). The rack is either controlled by a mechanical linkage or more recently controlled by vehicle software. With a rack there are usually no provisions to actively adjust toe in/out to compensate for ride height.

Could @borski or OP (@Osyris ) show/post the user manual for the Gravity? It might illuminate some of these questions.

A couple of test drive videos with Lucid chassis engineers revealed that the Gravity uses separately-controlled independent actuators on each wheel as the location of the rear motor precluded the use of the single rack most other systems use.

When it came to the question of whether Lucid makes use of that ability to angle each wheel differently, the responses got a little confusing. One engineer said yes, and the other said something to the effect of "we could".
