Cybertruck RTI (Ramp Travel Index) specs

[Owner13669]

I believe the website said you could raise or lower the height by 4 inches each way.

I thought the suspension numbers where in the Motortrend articles, but I have not found them yet if they are...

I'm, most likely, wrong - but, my recollection was that the 4" number was the travel for the adjustable air suspension. And NOT the overall suspension travel. The way I heard it the 4" would be how much the truck would raise and lower automatically (if set to do so) while driving - higher speeds the truck would lower itself for better aerodynamics. Higher speeds the truck would rise for better clearance.

This would have nothing to do with normal suspension travel.

Great! I'd still like to see the wheel travel specs. They aren't posted anywhere that I've seen.

I'd also still like to know how the structural battery effects the RTI if at all. My assumption is that the bottom of the CT with its structural battery pack, will be significantly more rigid then traditional 4x4s. All other things being the same, I feel like this rigid CT bottom would have a negative effect on the RTI (again, all other things being the same). However, I feel like I want the bottom of my 4x4 to be rigid and not flexing and twisting. I want all the RTI scoring to come from the suspension performance, opposed to the vehicle's ability to twist in a way that aids suspension and RTI score. And I want this stiff bottomed CT to perform comparably to the RTI scores of modern full size, extended cab/crew cab trucks. Somewhere just about 400 would be good enough to ease my concerns. The new Ram TRX is boasting a 605. I think Raptors are somewhere around 460.

To put that in perspective this Jeep Gladiator Rubicon score a 458 with the stabilizer bar connected and 607 with it disconnected.

Yes, it sure does. Now only if Tesla it would post some more specs.

I have only heard of estimates, nothing put out by Tesla, for the travel of the suspension or ride height.

We probably won't find out until next spring, when they nail down the production specs. But I hope for a Christmas present ^-^

I'm still hoping for a Baja 1000 present (17-22 Nov)...which would be more of a Thanksgiving present.

Even if it doesn't race, which I really don't expect, some overlanding, mild off-roading demos would be cool enough to keep me content until final specs are released.

I think we’ll hear more after the final prototypes have been built. (Just guessing)

I think next year is much more likely.

My old notes show a range of +3 / -3 inches of adjustment for a total of 6". At the stated 16 inches of ground clearance, assuming that to be max height, it might have 10" at it's lowest setting.

Since then, Elon said that he was revisiting the air shocks for better off-road capability but there is no word on it yet.

Yeah, I have not found my source, but my notes from when I was gathering specs had 16" max, but normal was 12" and had an range of 8 inches, 4" up and 4" down... Still not sure where I found that.

I also found a break over angle calculator that takes into account wheel size, wheel base, and ground clearance. That calculator spit out 24.1 degrees for break over. The length is offset by the ground clearance, as there are 'offroad trucks' with worse breakover...

from my notes:
SUSPENSION


Dynamically adjusts for load


Off-Road 2 - this mode provides the most ground clearance for the path and trail and generous angles for approach, departure and breaker. The difference from normal is +2.0 inches.


Off-Road 1 - like Off-Road 2 mode but with less rise. The difference from normal is +1.2 inches front and +0.9 inches rear.


Normal Ride Height - balance of ride and handling for everyday driving.


Aero mode - automatically lowers the vehicle, reducing aerodynamic drag and “body roll,” and measurably improves fuel efficiency. Only useable at highway speeds. The difference from normal is -0.6 inches.


Entry/Exit mode - automatically lowers the vehicle, making it easier to get in and out of your truck, load your bed or hook up your trailer. This mode is manually controlled by the internal button bank or remotely with the key fob. The difference from normal is -2.1 inches front and -1.7 inches rear.

Rex, good information, but I don't think there is a way to take that info and determine RTI or even definite wheel travel for the font or back while in those modes.

What is the source for this information?

I wonder. Electronic suspension can be optimized for off-road, great at speed (Baha), and great at crawling (The Hammers). My hope is this is how it's optimized. Not to suffer in any terrain, but be stellar regardless where. peace
