The best suspensión component explanation I've seen. Thank you !!
Isn't the tall spindle also to allow the upper ball to come over the tire and get more uniform compression?
I heard to give room for the tire since you can't install a bigger tire on a model 3
@bob15479
Too bad you didn’t try rock mode. The manual says for rock mode “When the ride height is Very High, the suspension system pneumatically connects the springs on the front and rear axles, increasing suspension articulation for maximum traction.”
Great video, but it is unfortunate that you didn't test "Rock Mode" as that would have likely completely changed the suspension flex result. From the Cybertruck manual: "When the ride height is Very High, the suspension system pneumatically connects the springs on the front and rear axles, increasing suspension articulation for maximum traction."
Would also be interesting to see it in the lowest height assuming it is possible to remove the aero kit in front of the wheels.
Really interesting video. I like these longer form videos that just take the time to explain stuff a bit. Well done.
I love how in depth you went with this video. Great job Dan and C&D.
Man i wish i found your videos earlier you carry so much knowledge and explain it very well (:
Probably one of the best/most thought out and instructive videos MT has released in a while. This guy is very knowledgeable and puts together video in a way which is just plain enjoyable to watch and listen! Great job!!!
This is car and driver not motor trend lol but I can imagine if this was on motor trend, your comment would stand.
Awesome video. Made me subscribe. I was a mechanic, now financial and insurance career for 22 years and always hated how automotive journalists have no idea how all this stuff works and about the engineering behind it all. Totally worth the money
Hahaha, suddenly there is a lot of new wannabe mechanics not technician. Publicity hound dog.
Finally someone who knows what they're talking about. Put some disconnecting sway bars on the Cybertruck and it should make it quite capable off road.
You got me subscribed while watching this video!
I really love those informative videos!
Impressive that you mentioned about the one-pedal driving and rarely needing to use the brakes except during an emergency stop or maybe after hard acceleration.
Air pressure can be measured on the infotainment service screen. So covers only need to come off to adjust pressure. Not to monitor them.
Shhhh this is Car and Driver, not a technical deep dive.
Yep, was thinking the same thing. I don't know if CT requires jack pucks, if so, none were used.
Why didn't it have auto onboard air?
this comment is for people that only drive/own cars right?
Dan (and everyone who drives/owns trucks) knows that pretty much every truck over 50k has had tire pressure monitoring forever...
He's telling truck owners information they need to know - that you can't easily adjust or check the tire pressure at the tire.
@@kelvinhelmholtz because, modern trucks tell us the pressure at the driver’s seat, remotely, automatically. On many many modern trucks.
Great detailed overview!
Really love these deep dives! No one else that I know of does this to this level of detail.
Really well done, make complete sense. Thank you!
Good, solid info. Well explained. Thanks!
Well done, Dan. You're definitely the go-to guy for these suspension deep dives.
Thanks for the excellent content. However, the Jumbo Jet is not a FBW plane as far as I’m aware.
very thorough work 👌 your knowledge of suspension is impressive; teaching people about front A arm bushing tuning :D
Air pressure CAN BE checked from INSIDE the vehicle on the main-screen under (SERVICE). So no need to even exit the vehicle to check pressure. Reviewers always seem to find and be aware of Tesla negatives but not informed or conveniently forget to mention positives.
Very informative, thank you:).
excellent presentation
25:35 why not use the remotethingqmabob?
Rivian was made to be the best outdoor adventure vehicle out there so no surprise it does so well.
lol!!!!! imagine if the tacoma or those other trucks actually have air suspensions! its going to be way better than the rivian period!
@@alanmay7929 No. Just no.
@@MountainManGuy of course its not going to have air suspensions, those things arent durable for actual heavy usage offroad.
@@alanmay7929 try that again off road only sell's kit's for TJ's ( 1 of the last off the line full-load'd-spec 🇺🇸 ) and my siblings jeep has them ( rear is dump-truck/simi bag's but that's because of towing reason's and wanting to max 8-12k lb's/ 1/2-ton-dodge ( for now 1-ton mod's are in the works ) total-trailer weight and or tung-loading, max-rear wood-hulling/my-v8 ( 500+ci iron hemi-charger ) is around 500-2500lb in the bed/backseat area ) and they do way better than the steel-coils/factory 4in~lift wouldn't go back , and yes day 1 family ( sibling is the 2d ownership, but it was RPO'd in for boomer 😉 ) had it in mud and rockying so it's never really been a mail-crawling/show-car
Excellent knowledge and explanations thank you for making this videos for fans and non fans of the Cybertruck
Great video. The merits of the presenter, Dan, made me subscribe.
Hi Dan, amazing video. I am wondering if you can provide with some measurements of the suspension geometry.
Why am i even watching this? I drive a small car and can't afford a Cybertruck 😂. Im watching this because I like technology I guess.
To check the air pressure, see service menu on screen. But yes, to fill tires with air the hubcaps must come off.
I got a lot out of this video. Thanks.
12:12 We've had to replace the rear brakes on our electric vehicles because they corrode/rust --- because a) they do not heat up and dry from rain/snow/etc and b) the rear brakes do less than the front brakes so even when you do require manual braking (vs all regen) they don't heat up. VERY important to get your brakes cleaned & lubed annually on electric vehicles as pins corred and pads don't slide so may wear prematurely. I've experienced this as well putting off clean & lube one year.
Great walk through. I learned alot here.
420 and a 69 mixed in there.. 😂classic tesla move.
Wondering if the load rating D on those tires will be sufficient as my F350 had E rated for my trailer.
I feel like the right front lifting has more to do with it being air suspension than the weight distribution?
You are VERY good .... Thank you !
28:45 - i was expecting suspension levels changing while on ramp. Will be interesting to observe behavior. Especially after driving in on ramp in lowest position and then switching to highest
30:20 - rear wheel self-steering under load :) Steering rack is a bit flexible. Guessing rear right wheel shoul turn same direction.
well done video.
How do you know all this? That's so much complex, detailed information on the wheels. Thank you!
He is an instant EV genius. Publicity hound dog.
Thanks for another great video Dan. Your videos are very educational and I love the informal yet professional nature of the production. Very nicely done. Please keep ‘em coming.
The gladiator rubicon is at the top if you have the swaybar disconnected
Great video, thanks very much.
It doesn't appear to have much if any caster in the steering, so I'm guessing the electric motors return the wheel to center as part of the programing...pretty cool.
Where is the lighting flex test? I don't see it in your videos
I would love if you do an update video referencing back to this video where you do the ramp test again with the updates that better tune the back motor and adds in the locker in the software for the front tires to see how the performance has changed
Unless it tunes the suspension differently, it won’t matter. Once any tire lifts, the test is over.
@@Mittens1234Oh, interesting, though i am still curious how far up it could go on the test even with tire lift in the future.
I think i saw this guy in modesto ca this morning.
Well done on the Sub frames and cross members. More like a SHD truck for sure. Air ride has to be a must otherwise it would be very rigid and stiff ride.
I thought the owner's manual said to remove the mudflaps and the front deflectors when doing rock crawling and such.
I'd rather have an RTI in 369 than an STI in 169.
24:10 what’s with all the creaking when you steer?
Tire scrubbing on the pavement.
A future software update could allow way more flex by increasing the air pressure in the air dampeners that aren't touching the ground. Each dampener can be controlled individually so when it detects wheel slip it could push down the dampener
I get the impression that Tesla will do a lot of software turning on its suspension.
It would be great to see the Ineos Grenadier Test...
Rivian is a beast of a truck.
In the video you said 2. Seconds for the 0-60. 2 point what seconds? Or did you actually measure it at 2 seconds flat? I don’t imagine that could be the case
It's 2.6 seconds
2.6 seconds. See our full road test with test results here: www.caranddriver.com/reviews/a60115630/2024-tesla-cybertruck-beast-test/
Fastest truck ever!
You said that the suspension gets stiffer when you raise the suspension due to higher air pressure.
That's not how an airspring is working if you drive a truck the pressure is the samme in a low setting as an raise hight.
When you raise the air suspension of a truck you put more volume of air in the suspension, but the airbag is not an ballon or a tire what happens i that the airbag is slides up and down on an iron cone so no matter the hight the pressure will be the same.
That's why it is easy to make DIY weight scale on a truck so you can tjek the vehicle isn't over the weight limit.
Hope you understanding my very pour English
Thank for a great video
Yous truly
Brian from Denmark 😊
its not entirely a 48 volt system , also has 12 volt for some accessories.
Is it important to differentiate frame flex from suspension articulation?
Good question.
It it adds grip it ships. I have a fairly identical set up 1st gen frontier and 2nd gen pathfinder. The Pathfinder has a fancier rear suspension, likely more travel in the front, and a limited slip in the rear vs an open diff in the frontier. Unfortunately it also has a stiff unibody . The frontier creaks and twists over things while the Pathfinder will get 2 wheels off the ground.
Model Y owner. The air pressure can be checked from within the vehicle or through the mobile app.
Not the point
Can you change the air pressure in the app or the screen?
That's standard for most new cars. But I don't think that was the point.
Is that a press vehicle? It has a manufacturing plate.
PRODUCTION vehicle.
Probably, this is Car & Driver and they usually get cars str8 from the manufacturer for tests. Plus it's a Cyberbeast which I don't think is being delivered to customers yet, not sure
@@quackman - Cyerbeasts are being Delivered, older Videos exist.
@@markplott4820 Yes, my mistake on that latter bit.
This is probably a press vehicle though w those plates (which may mean it's also production; the terms are not mutually exclusive)
As someone waiting for a delivery on a cybertruck, I couldn't care less. I will be doing absolutely zero offroading . I will however be launching it hard probably multiple times a day, so I'll enjoy that acceleration and I hear it has a nice stereo.
Gladiator Rubicon (Bar Off) not shown?? Rti score 607 on your previous video. Kinda shady you're not including it, but are including Tacoma Disconnected...
I love how they made the upper control arm out of a tin can
recycling at its finest 😂
Also remember its bolted straight into it's aluminum frame.
He explained why it doesn’t need to be beefier. 3:42
The upper control arm doesn't need to be beefier because the axle joins close to the lower arm meaning that leverage causes all the load to go through the lower arm - hence the lower arm being a beefy cast component.
@@ericy.2108 But it does. theres only been a few hundred made and already the wheels are falling off
car & driver - aero wheel covers actually reduce DRAG.
but , also Excessive wear , so they were Recalled.
They never delivered them with aero covers.
@reyfetsalmo3346 as you can see, this one was.
@@reyfetsalmo3346they did, the first few were
I would love to see you measure our Gladiator Rubicon
How often am I having to buy new tires (give me an average distance, someone that’s knowledgeable) and what’s the cost of a set of four new replacements?
Completely depends on how many drag launches you perform on a daily basis. There’s nothing inherent to EVs that makes them worse for tires than ICEs except for how easy it is to call up all the torque all the time and not get attention for it.
check back in a year when people actually drive it more.
@@EUC-lidEVs are heavier and therefore have higher ware and tare.
@@parsonk4041 an M340i and a Model 3 are within 10lbs of each other. The BMW wears 225/45R18s to the Tesla’s 235/45R18s. Try again.
@@EUC-lid So EVs are lighter or weight doesn't impact ware?
Love you videos but why do you have the gladiator not at your rated top 607? Makes no sense.
I wonder if they wanted to switch to steer-by-wire on the new model S but couldn't fit it in but the yoke remained
I wonder if we'll see a smaller "light-duty" version of the Cybertruck.
I wonder if the single motor RWD model of the Cybertruck will come with rear steering 🤔
There isn't single motor model. They got rid of the option.
I feel bad for that jack! 😅
It's 6600 lbs. That's lighter than the lightning and rivian and in the range of a full sized truck.
@@jasonsstratton stop crying at every comment. Elon won’t notice you.
A full size F-150 is 1,900 lbs lighter, lier. Let alone Cybertruck isn’t even a full size truck. It’s less practical than a Camry.
@@OmarZ77 braindead
@@OmarZ77 I think you're the one that needs to stop crying, it has more payload than any F-150 currently on sale and more bed volume than the most popular F-150 variant. By saying it's less practical than a Camry you're the typical npc who thinks they're in the know when in fact you're just signalling your ignorance.
@@boostavCome on. As if the bed size is the selling point.
These vehicles get progressively larger and heavier, at what point will a “commercial” driver’s license be required because of the GVW AND combine GVW?
26001 lbs
You can go rent a 26,000lbs u-haul today without a commercial license. Think about how much more dangerous those are because drivers are unfamiliar with the vehicle. Large vehicles you own are not a big danger as everyone wants to make out like they are.
Rivian being so high up there might explain why it went up that "it's not a trail" by the hands of Doug DeMuro so capably. I'm curious for their shorter SUV's score.
The CT has more clearance than the rivian.
@@jasonsstratton stop crying
@@jasonsstrattonits about suspension configuration and rivian has hydraulic/hydropneumatic suspensions like citroen.
@@alanmay7929 it's not nearly as rapidly adjustable as the CT.
@@jasonsstrattontoo bad the clearance doesn't seem to help.
The air pressure is displayed on the screen inside the truck.
Not the point
The amount of cannabis involved in the making of this vehicle must be legendary.
Not even a stoner would design something so fugly
More like meth and ketamine
@@trance9158 Yes I would!
Comparable to, the amount of cannabis used by this review, before the review was written.
Or the lack off
1.3% areo benefit to the wheel covers per other C&D video? [10% for tonneau cover]
Nice in depth video, will you test again with the sway bars disconnected? Assuming tesla will offer optional disconnecting sway bar links in the future
If Tesla does not others will. After market is growing.
Those aero covers are also eating away at your tires on every rotation, they are eroding the sidewall. Cybertrucks no longer ship with them.
Watch your vid at 23:54 to about 23:59 and look at the lower part of the door when you close it....
Can you retest when lockers are available and also remove the mud flaps? I'd be curious to see what low nets you in that scenario.
it will not help because the wheels are already lifting from the ground thats where he stops for measuring.
@@alanmay7929 I think you're correct for the hight of the suspension he tested, but I think he stopped at the medium setting because he was worried about the mud flaps hitting the ramp. Having it in low may net a bit more travel since the bags will have even less air in them. If I'm not mistaken the owners manual also says to remove the mud flaps before going off-road. The ones in front of the wheels are on there for aero. Similar to the front air splitters a lot of trucks come with.
@@piemanklpwrong!!! he drives up the ramp till one of the 3 remaining wheels barely touches the ground then stops to measure thats how it works
@@alanmay7929 doesn't the right front tire lift at a different point based on the suspension setting? I thought that was the difference between the two different heights he tested and the two outcomes observed in the video?
@@piemanklpthe front tire isnt supposed to lift unfortunately! this is about testing the flex of the vehicle/suspensions.
it will definitely go a bit higher with the "locked diff" mode. I have no way to say how much higher though. they will 100% do it because its just a sofrware update. also because its so vertically integrated and almost all electronics are made in house and sharing the ethernet data connection, it shouldnt be really that complicated . they will never miss on the opportunity to improve a product significantly with just software which is the easiest way for tesla which is not only a car but also a software company. a
Also looking at the air suspension , it is most likely that they could go much further and dynamically adjust the suspension height independently on each wheel. this could only work in a slow rock crawling mode because rhe airbags will take seconds to adjust, maybe about 10s from lowest to highest. I can see it outperform off road truck in artculation test with an additional 4 in in each direction
Check air pressure on the display. Just like my Subaru ..
dude, you can check the air pressure on the screen, oh m g, you really didn't know that?
Maybe you can test a Mercedes G Class. This would be awesome
You CHECK the air pressure electronically.
The mud guards probably come off for offroad.
Barely 4 minutes in and wondering why the brakes are grooved so bad. My Rivian is showing nearly zero wear at 27k miles.
Was your R1 a press car being tested for braking performance?
@@EUC-lid looks more like a rock caused that than hard braking.
@@EUC-lideven if you test it down to the metal this looks horrible.
@@parsonk4041 outside of carbon ceramics, brake rotors are iron or steel. “To the metal” implies there’s supposed to be another layer. Other than a microscopic layer of brake pad material transferring over, it’s all metal.
Some grooving is normal, especially when overheated/abused (such as during instrumented tests). BEVs default to regen, meaning they often suffer from not using their brakes enough on the street to cook off water, resulting in extra rust (particularly where road salt is used).
Maybe it is the truck that haggerty ran on the go cart track. Brakes were glowing red.
Surprised the hubs are so rusty already
I recall seeing a Tesla model 3 or Y climbing a similar test. I remember being impressed at the balance allowing the front wheels to lift off and i remember thinking it was a good thing. It allowed the vehicle to climb much higher.
I think you could climb further of you weren't afraid of the front wheel lifting off. Add just a few pounds of weight to the bed, I imagine a sand bag will do, and try again while allowing the front wheels to lift. Please. I suspect it will climb to the top of the ramp.
The point was to get to just having one tire almost off the ground, not to climb all the way up the ramp, which he basically said it could do.
@@billstevens3796 Oh, so to an arbitrarily pointless point. Got it.
This truck is screaming out for some @74Weld portal hubs.
A moment of silence for Dan's mic
7000 lbs. insane.
Wow did they finally solved the cap tire rub issue?
Excellent presentation. Very interesting.
Not a vehicle for me.
Yeah? What do you drive, Ford Taurus?
@@sergemarlonwhat's wrong with a Taurus.
@@parsonk4041 Nothing I'm aware of. Why do you ask?
@@sergemarlon because of your comment that seemed dismissive. But I understand and agree with you now. The Taurus is a superior vehicle.
@@parsonk4041 Agreed. So what do you drive? I'm still curious.
You glossed over a critical point ! The Jacking point and required Pad ? I see your jack had a round pad , Is there a hold like the model 3 for the jack point ?
Elon says to the engineers: ok ok what ever you do its gots to be 420
You can check the tire pressure on the screen just click on the service button
Not the point

wow, those numbers lol
That 1.5 ton floor jack didn't strain lifting the 3.5 ton truck
It didn't lift the whole truck
its from Harbor Freight , its going to Break.
@markplott4820 not! I've had 2 jacks from there. First one, after 20 years, had a very slight hydraulic leak. Still worked fine. Bought a second one rather than mess with it. I fully trust them.
Significant digits, Dan. You can't go out 4 decimal places on a tape measure. 20 9/16 should be written as 20.61 in decimal form.
Please don’t tell believers in the digital metric system, that, mathematically speaking, fractions are much more accurate. Ssshhhhhhh🤫. Don’t tell.
@@pauljefferies9087 Inches (and thus fractions thereof) have been SI units (which are based on metric units) in the USA since 1933.
1” = 25.4mm
It’s been a 91 year charade to keep tradesmen feeling a sense of misplaced patriotism.
You need to take those wheel caps off. They will ruin your tires. Tesla stopped sending that cyber trucks with them until they figured out a new cap solution.
TESLA has NEW tires that are not off road and come w/ NEW wheel covers.
The wheel covers absolutely make a difference. For #1, range. #2 they look sick as hell.
I'm not a fan of plastic hubcaps. If that design was actually an integral part of the wheel, I'd be more okay with them as I do like the look.
@@ALMX5DP Same
@@ALMX5DPthey probably have to be made out of plastic because they could become a hazard if the come off and they are made out of aluminum or something.
The reason that they look different is because they go over the tires, if they didn’t they would look just like any other wheel design.
I guess it’s a trade off of trying to make a different design go on a production car.
I have never heard anyone ever say that wheel covers look sick.
@@salahad-din3907 since the entire wheel is Tesla specific, it really should be one part.
Someday, I'll get my CyberBeast ❤
