Let's talk ramp inside tailgate...

[bruce91748]

If by "step up" you mean the distance from the lip of the lowered tailgate to the ground, it's not a foot, it's probably more like two feet. We won't know for sure what that distance is until we know the spec's on the adjustable suspension when the truck is in the kneel/squat mode.

An answer to this question, with assumptions for those specs, can be found here: https://www.cybertruckownersclub.co...-ramp-inside-tailgate.9447/page-5#post-185994

Need to add another 24" to the tailgate as there's another swing out gate that goes beyond the 2' height of the tailgate, totaling 48" beyond the bed and go down another 15 degrees or so pass the pane of the tailgate. Refer to the picture if in doubt.

to date, there's been no evidence that any RC/MC build can 'lean' back (eg independent front/rear height adjustment)

so, i think earlier calculations - which factor in lean - are a bit out over their skis (ramps?)

you saying it can squat?

“squat” and “kneel” etc are all terms also used to denote when a car is fully lowered, eg to an entry/exit position. All 4 airbags deflated.


Same terms are used here sometimes to instead denote a different posture: the front bags are inflated to max height, while rear bags are deflated. It’s this posture for which we have no evidence the Ct is capable.

Let’s call that posture a “loading” mode.

This latter sort of control isn’t, as far as I know, found on any stock vehicle with “independent” air suspension. In stock vehicles, the “independent” nomenclature relates instead to auto-leveling to ground, eg., in response to a load in the rear. In which case, the sensors/bags are working independently to maintain the vehicle level to ground (suspension in same height), not horizon (suspension in different heights). The reason these OEM systems don’t have/allow for adjusting to different heights front and rear I suspect has to do with complications/stress in the geometry of suspension and stress to the air system.

Conversely, however, is Rivian - which since 2022, offers a horizon-leveling setting eg for campaign. That sort of leveling can take anywhere from 20 seconds to a few minutes depending on the unevenness of the terrain. It won’t work with tailgate open. It can only adjust to about 3° in difference (or about 5” delta in lowest to highest corner). It doesn’t have a loading mode (and if it did, may take a few minutes to reach that posture). In any event, the Rivian suspension overheats easily if attempting too much adjustment - locking out the vehicle suspension until cooled, and limiting movement to 8mph.

There are other vehicle applications, like RVs, where horizon leveling is offered - but those are very different suspensions that don’t need to perform like the suspension of a vehicle that also promises offroad suspension travel and sports car performance, etc. And they also have minimal adjustment.




None of which is to say the Cybertruck won’t have a “loading” posture (unlike Rivian), or a horizon-leveling posture (like Rivian).

Instead only to point out:

(1) we’ve yet to see any evidence of this in either an RC or MC, or any alpha/beta - only the single 2019 prototype has been seen in a loading posture.

(2) the limitations of the Rivian system (no loading posture, minimal and slow horizon leveling, etc.), together with the lack of loading/horizon leveling on other OEM air suspensions, goes to show that it’s not merely a matter of having air bags and a software setting.

(3) for the reasons above, to the extent the CT does have loading/leveling postures, they may not be as wieldy as what’s in people’s imaginations (eg slow to adjust, minimal adjust).

C,

My Rover had a separate remote that would drop the rears only. They advertised it at the time for hooking up a trailer. You bottom out the rear, back up under the trailer, and then hit the up button on the remote and the rear inflates up to hook up the trailer. Pretty easy.

true enough. And a few others have similar capabilities for hooking up trailers.

I glossed over that for two reasons

Onthe River, that was a special option requiring a separate key fob and with limit utility otherwise.

But more to the point: that function allowed a rear drop max of2.36 in rear only, while front stayed static



So you’re totally right, but I glossed over it to the extent of how it relates to the practical realities of how these OEM systems are very limited in nature - in the context of the comparisons that were being calculated for the CT, which assumed you could do max height lift up front, and lax lower in rear

good add though, for same reasons. Still, I think, makes the point/comparison I was intending

The new RAM also has a trailer hitching mode with air suspension.

No swat w/ lean back function means no CT for me.

Don't existing Teslas already do this, but in reverse in Cheetah Stance?

 

[Cybertruck 1974]

No ramp. All good. Let's talk rear suspension lowering...problem solved getting into bed area.

 

[kbolt]

Elon has said on multiple occasions that he hates when a cat company comes out with an awesome prototype and then the real thing is a let down and completely different. So I'm taking everything from the launch event as gospel.
They had certain prices shown: gospel. They had certain specs shown: gospel. They had certain ranges shown: gospel.
They had certain features shown: gospel.
Until Tesla says otherwise it's still gospel. The ramp was shown so it's gospel.

yes, and that's another good example

only the front lowers, and only <2" - meaning the suspension deals with a net difference between front/rear of center by <1"

I can't tell if this is /s, but point of process: he ONLY said he doesn't like it when the production version LOOKS different from prototype

he's done a pretty good job there

in terms of functionality or features, he's said no such thing

 

[bruce91748]

No ramp inside tailgate is a let down but we already expected the truck not to have it weeks ago. Now has anyone seen the truck do the backend kneeling all the way down while the front goes all the way up? If truck can't even do this, I'm not sure if I'll go ahead with the purchase.
