The military Humvee/Hummer H1 has an independent rear suspension. While it is definitely an "outlier" it is a good example of a heavy duty independent rear suspension and maybe worth comparison. Love the videos and expert opinion, always look forward to more.

[@4G12]

While the Humvee H1 is the most famous 4 wheeled fully independent suspension vehicle, if you include vehicles with more wheels such as armoured wheeled vehicles, fully independent suspensions are the norm nowadays. They have no major issues with massively varying heavy loads such as varying armour, weapons and ammunition loads. Independent suspension is also superior from the service and survivability standpoint, if you blow up one wheel out of 7 thanks to a land mine on an 8 or more wheeled vehicle, you'll survive and have more than enough mobility to limp back home for much easier repairs since you'll only need to replace one wheel or at worst, one suspension module, instead of both sides getting affected.

[@richardlockwood999]

@@4G12 I'm a humvee fan and love the ground clearance, but it still suffers lack of suspension travel. The problem with independent suspension is lack of suspension travel. While there's some custom baja and King Of The Hammers off road that have decent travel, no civilian/commercial vehicle has proper long travel independent suspension. Partial credit to Ford's Raptor IFS, but for off road use, we need true long-travel independent suspension.

@@karenrobertsdottir4101 Serious off road independent suspension have much longer control arms, which makes the vehicle wider. The other way to make control arms longer is to move the suspension mounting points toward the center of the vehicle, doing that gets in the way of the engine and vehicle interior. this is part of they the humvee has such a small interior space. they had to move the engine backwards into the vehicle interior space; something that would be unacceptable in a civilian truck.

To me it seems crazy that other brands haven´t even looked at Citroën´s brilliant hydropneumatic system. It´s been around since 1954 and solves every possible problem there is. In 1995 they launched the Xantia Activa which are fully active even with roll correction. I rides like a Rolls and are still at the top by the supercars when it comes to handling. And it was a competitor to the VW Golf. I know some people without knowledge may comment about reliability. But i have worked with these cars for thirty years and can tell that they are really reliable. My old DS btw has over a million km on the clock, and in my twenty years with that car i haven´t had a single failure in the hydraulics. In fact, they are far more reliable than normal types of suspension. And as a bonus, you have real oil in the brakes. No hydroscopic brake fluid=no internal corrosion. I know the DS is the last you got in the US. But ask anyone about these. It´s the best ride in the universe, and they can take crazy amounts of load AND they handle so good that they are considered to not need any ESP. Would be really interresting to see Munro have a look at an old Citroën. PS. I may take it bit too far here, but I would say that the Citroën system is the ONLY system that really can adapt to all situations like empty with driver to fully loaded. That is because the size of the shock absorber is adjusted exactly to the load of the spring. And I think that´s only possible when the "spring" is a gas and the "shock" is a fluid. And the Activa has real-time hydraulics for roll-correction. And when driving straight ahead, it goes away by allowing the fluid to interact with a gas accumulator. So it has limitless flat cornering while having no anti-rollbar at all when not needed. And as we all now, anti-rollbars ruin comfort.

[@67daltonknox]

I owned a GS with the hydro-pneumatic suspension back in the 70's. It had a very good ride and good handling. By that time Citroen had sorted the system so maintenance was minimal. At idle, the suspension powered down, so the struts would settle on to stops. When the engine started, it would rise up, bit like a camel, before you drove off.

[@EVPaddy]

well, I remember the wait before you could take off in the Citroën of my father when I was a child. Wouldn't see that as an advantage.

[@67daltonknox]

@@EVPaddy.The Bilstein system keeps the strut pressurized at all times. There are many reports of early (expensive) failures in online threads. The Citroen system may have been more reliable by not pressurizing while parked.

[@michaelheimbrand5424]

@@EVPaddy Should not be any more than a few seconds. Anyway, Citroën eliminated that in the early 90´s with the SC-MAC system and since then they never sink over night. The "problem" was actually not ever a real problem. The system was designed with a small amount of internal leakage. The "anti-sink" was more a market (stupidity) thing. To sell more cars, everything needs to be the same as everybody else. It gets worse... Citroën´s market leading brakes were always very sensitive in a good way. But that meant that people used to other cars was surprised of the high power in the brakes. So in 1990 they introduced a damper which made the pedal feel a bit..well, worse, more like a conventional old-style manual/vacuum-boosted.

[@michaelheimbrand5424]

@@67daltonknox A Citroën is always pressurized. Older models may have been sinking over night, but not newer. And that only affect the hydraulic part. The gas accumulators are of course always pressurized. But i am not aware of any case of something dangerous happening. They are so overbuilt i bet they survive any kind of damage including direct hit by nukes. Cars with springs etc. on the other hand is more scary i think.

[@the.original.throwback]

Thanks for continuing your video series on the Cybertruck. I reserved a Tri-motor Cybertruck immediately during the reveal and am closely watching Tesla for design details. We have a Model X and the air suspension system is superb. I also have a 2005 GMC 2500 Yukon XL with Quadrasteer. It is an amazing feature that makes a large vehicle nimble as a small vehicle at slow speeds and adds significant stability while towing. Up to 45 mph the front and rear wheels turn in opposite directions to provide a turning radius similar to a compact car which is awesome in parking lots or when backing up a trailer. Over 45 mph, the wheels turn in parallel which reduces longitudinal instability while changing lanes on the freeway, especially useful while towing. Unfortunately, GMC not only abandoned Quadrasteer technology but also quit making replacement parts so owners of these expensive vehicle are scrambling to keep them running. I keep waiting to see four wheel steering brought back by manufacturers of long wheelbase vehicles. I believe it will open up a market by serving drivers who want a large vehicle but dread maneuvering them in tight parking lots. Waiting for the next episode. Jess

[@mattferguson9109]

I guess you were prescient in regards to rear wheel steering! Looks like most of the newest electric cars are getting them.

[@creatorgenerator1998]

[@martylawson1638]

Solid axle vs independent suspension for towing is a red-herring. Just look at any of the heavy duty Oshkosh military trucks or Tata trucks designed for off-road. They almost universally have independent suspensions on all tires now. Regarding active-damping. If we assume that the air-ride suspension self levels with a digital control valve, the suspension already has the position sensor necessary to tune an active damper. So the only additional expense would be the variable valve assembly and software.

[@KcK702]

Great video!

[@ltkwok]

I think what Sandy is saying is that the air suspension is kinda expensive for a $40,000 vehicle and it will be hard for an independent real suspension (instead of a solid axle) to have the towing capacity claimed in the Cyber Truck. Electrification aside, if Tesla can do this, it will force the other truck makers to follow & we, the customer benefits.

[@MFZero2]

I still don't get it, but I trust you.

[@markplott4820]

LTK - CT will have Rally Truck suspension. it can WIN the Baja 500. CT also has LOAD kneeling , a FIRST for a Consumer Vehicle. while I don't think Tesla will have a "MagnaRide" suspension, it still will be very good/excellent.

[@honeymanod]

My guess is they will have a towing option in the user interface that locks the rear axle at the motor to improve towing, and when you are not towing, it release the rear axle so the wheels can move independent again. So you get the best of both worlds.

You probably already know this: I used to have a 1965 Ford F100 with the heavy duty package. Rode pretty good, stiff from the heavy duty suspension (I had 35 high school kids on it in a parade). It was a pick-up. Several years later a film producer gave me a ride in his 1963 Rolls Royce Silver Shadow. Just as I realized it rode exactly like my old pick up truck he said, "How about that ride? Is anything as smooth?" Of course I said, "No, it's amazing." Bar none the absolutely smoothest riding vehicle I was ever in was a 1970s Citroen with the big air balls under the hood. Totally unreliable, but it just floated along. I was in a van that was set up with an air suspension for a disabled person but I guess the air system was just for leveling.

[@andrewford7437]

Love the cyber

[@fields1]

I know some people think you have to put a solid rear axle on a truck or it’s going to be too light duty in rough and tough situations, but I watched a video of a test of the Ridgeline vs. a couple other trucks in extreme conditions. Shockingly, the Ridgeline was the only truck (also tested was a Tacoma TRD Off-Road and Nissan Titan XD Pro 4X) that made it down this extremely long corrugated road without both rear shocks failing. I personally think with a cross-linked air suspension, you can have an IRS without losing the ability to have excellent articulation. Besides the ride quality improvement, one benefit of ditching the solid rear axle is that you no longer have the huge diff housing that sticks down so far below the other underbody parts and is often the lowest part of the vehicle. An example of IRS that is insanely good off road is any modern Land Rover/Range Rover vehicle equipped with air suspension. They manage a phenomenal on road ride with the extreme off road capabilities other brands’ vehicles don’t offer. The AM General Humvee is also equipped with 4-wheel independent suspension and it can climb and crawl over anything. Here’s the link to the Ridgeline torture test from Edmunds: kzbin.info/www/bejne/eYi8onifo7N6i68

[@bradley3549]

I agree. Some of the most capable suspensions in the world are independent. When cost is not a concern, independent is going to always win. Durability per dollar (both in initial cost and in maintenance cost, I think solid axles win. It's worth noting with the Hummer H1, it's towing capacity was rated lower than the solid axle H2. Now whether that is due to just being a huge heavy beast or because in part the rear independent suspension is a liability in heavy towing? Maybe just a matter of H1 buyers not being big into towing. Who knows. But it's an interesting observation.

[@alanmay7929]

mercedes still uses a solid rear axle even front axle on their military G wagen and normal and that thing like the Unimog has three differentiels and also air suspension and tire inflation systems.

[@fields1]

Alan May the current gen G-Wagen has switched to an IFS and retained the rear solid axle. It’s really stupid though. Watch a video of the new G and it has pitiful suspension travel because it lacks air/hydraulic suspension. The front looks like it may have 6-7” of travel. My Land Rover LR4 on the other hand seems to have 12-14” of front travel and the rear even more. Many features in the G-wagen are just to make people feel special. There’s really no reason for Mercedes to fit 3 manually (push of a button) diffs to a G550 or G63 AMG when the ground clearance is so poor due to the low hanging side exit exhaust. They do it just because the people who buy those things are compensating for something... if you know what I mean. Those three buttons (that 99.99999% of owners likely will never use) make them feel like they’re invincible. In reality their $5000 side exit mufflers will get hung up on the mildest of obstacles as soon as they step off the pavement.

[@fields1]

Bradley Weingartner I think you also need to think about the fact that the Hummer H2 was just a Silverado 1500 in drag explains why the H2 was able to tow more. The Silverado is designed from the ground up to tow. The H1 was just a military expedition vehicle made road legal. They didn’t design it from the ground up to tow a lot. The transmission, engine, frame and suspension weren’t really modified from their original design. The Humvee was made to crawl over insane obstacles in the desert or mountains. If it had air suspension it would have been a different story since the air bags can inflate to level the vehicle. It’s also funny when you see pickups with heavy trailers behind them and they’re slammed to the ground in the rear while the front of the truck is pointing to the sky. The Ram with air suspension (just like any other vehicle with auto-leveling suspension) will always maintain its driving composure and comfort even when a heavy trailer is behind.

[@bradley3549]

@@fields1 Like I said, just an observation. Could be a lot of factors unique to the HUMVEE platform contributing to that rating, including the portal axles that may not cope well with the heat of sustained towing, the midship engine resulting in a near 50:50 weight distribution, Bottom line, I have every bit of confidence an IRS could be designed with towing in mind. Not so sure it can be done at the right cost to justify it. Tesla is in a unique position in that it may have been more cost effective to just improve upon an IRS since they do not have a traditional platform to start with.

[@chrisrijk6055]

Great video. My naive guess for the tri-motor Cybertruck is that with isolated electric motors on the two rear wheels and with air suspension there would be no need for any kind of mechanical linkage between the rear left and right wheels - the motors would run at different speeds to handle the job of the differential and the air suspension would handle the job of an anti-roll bar. I've no idea how this would affect real world towing capacity.

[@JasonWW2000]

Doesnt it make more sense it will share the dual motor rear assembly from the Model S? Air is too slow to act as an anti rollbar. A normal rollbar will work.

[@chrisrijk6055]

@@JasonWW2000 Model S dual motor has one motor for the front two wheels and one motor for the rear two wheels, so still need a differential. Tri-motor would need something very different. With regards to air suspension replacing an anti-rollbar, apparently it can be done in theory though I've not found any real world examples: www.tandfonline.com/doi/abs/10.1080/00423114.2018.1552005

[@JasonWW2000]

@@chrisrijk6055 The tri motor would not need something very different. I have not seen any pictures of the dual motor rear assembly (Plaid), but the only way to fit it into a Model S is to relocate the inverter and put the 2nd motor in its place since the motor is the same size and shape as the inverter. The inverter can be remade into a new shape (it has to be larger as well) and be relocated nearby. The 2 motors can feed a single gear reduction and differential. The 2 motors can even share a common shaft, but I doubt they will. I suppose the two motors can be fully independent if the each have their own set of reduction gears and then you can delete the diff. The twin sets of reduction gears can sit side by side in a single housing.

[@blackoutsi]

My theory: I think it's more of a rigidity thing. Wishbone suspension has at least 4 rubber bushings to connect to the frame per side, which under heavy loads will shift around more causing the back of the truck to feel less stable and planted. Each side can be affected independently so you can get oddball handling under load. With a trailer and larger tires this gets amplified. If you made those bushings into bearings or a stiffer material, it would transmit all the suspension and road noise into the frame and wears out quickly. With solid axle the bushings are in different orientation more in line with the loads and the axle itself is structural so it all moves as a single unit. This makes it feel more predictable but rides a little worse, and it's also cheaper than CV axles so the traditional OEMs stick with it.

[@chrisrijk6055]

@@blackoutsi Good point. If the rear axle is providing some of the overall structural rigidity in a traditional pickup truck then the stronger the axle the better. But with exoskeleton style Cybertruck, so long as the body itself is strong enough then there should be no need for the axles to provide extra rigidity. Might need some additional strengthening though, depending upon how much you want to tow.

Theoretically, yes, motors could be dedicated to specific rear wheels and eliminate the need for a differential, however, if Tesla intends to share the tri-motor "Plaid" powertrain between the Cybertruck and other vehicles in their lineup, then it may behoove them to keep things common with the motors positioned in the middle. Other OEMs (like Volvo, for example) have packaged two electric motors on the rear cradle and maintained independent rear suspension, so it is certainly do-able. Thanks for tuning in!

[@Manish-lk8pi]

@@MunroLive Thank you :)

[@gustavlicht9620]

Tesla could use a de Dion tube for the rear suspension to get good towing capability. Ford did in on their prototype electric F150 in the early 2000s.

[@jameshoffman552]

18:00 'Don't think you'll see active damping on the $40k CyberTruck' Maybe, but I think more likely that the features besides the powertrain are identical on all three models. Most of the cost of active damping is the air suspension, which all three will have. Also, between the 3 models CyberTruck may be the most-produced vehicle with active damping, so the economies of scale would also cover the expense of such features in the entry model.

[@barrettabney]

I remember Consumer Reports rated Ram trucks as the best riding many rears in a row. Now we can see why.

[@linc234]

while I don't know the specifics of active dampening systems, theoretically they could be programmed to simulate a solid axle. Similar to how most modern trucks have a 'tow' mode switch.

[@M4166262016]

Awesome awesome video...

[@jonnysrods]

Sandy, Thank you for the Video. You can compare the Cybertruck Suspention more directly to the 2007 Ford Expedition 4x4. I have one with a 3" strut lift and 35" Milestone Patagonias

[@mini2nut67]

I predict the truck will use an independent rear suspension. A HD rear suspension and motor(s) will arrive preassembled to the factory assembly line in a subframe which then gets bolted directly to the unibody. The subframe will also add rigidity to the rear end of the truck. It will help when service is required because it could be easily removed.

[@anonymous.youtuber]

Another brilliant presentation ! What is going to be the impact of in-wheel motors on the driving experience ? Will they become mainstream or not and for what reasons ?

[@blackpearlaruba9227]

Big rig all Aire suspension in EU, I did like it a lot.

[@seb.]

even the trailers in some cases

[@unclezeppy]

I'm just thinking what if the Cybertruck will use kind of a motocross bike style rear suspension with built in driveshaft on each side with motors under the rear seat. The reason for the CT side design is there is a triangle shaped suspension part inside the truck bed side panel.

[@DouglasEKnappMSAOM]

What is crawling and walking when towing? Why does it happen? Could be be overcome by monitoring and computer control to the two real wheels?

[@DavidOfWhitehills]

Yeah I was wondering the exact same.

[@TimLF]

When you put a heavy load on an older under engineered vehicle it tends to lean back, to the side, travel sideways, and starts steering like a boat. This is because the bits between the road and your load flex out of normal driving tolerance.

[@DavidOfWhitehills]

@@TimLF Thanks for that Tim. So the CT will need a pair of massive "intelligent" suspension units to counter these forces.

[@TimLF]

@@DavidOfWhitehillsJust modern well engineered hardware, the electronics are a bonus.

[@JesbaamSanchez]

Great video! I found this very informative. I did have one question, when mentioning about the leaf spring system. My dad has an F-150 that has a spring and a leaf system on his truck. He uses his truck for carrying loads like tiles and he is looking for a truck that is able to take a full pallet of tiles. He already reserved the Cybertruck (cuz I tolded him and we both looked at the specs). After seeing the video my question is would the Cybertruck be good for carrying loads from time to time?

[@JesbaamSanchez]

Or is it more just for looks and luxury?

[@mubbywub]

The design expectation is that it can regularly store and tow significant weights, it’s just a matter of pulling it off.

[@jeremyjohnson6438]

A tiny tiny percentage will tow anything with the Cybertruck and and even less will tow anything over about 6k to 7k. Most people in that range opt for 3/4 ton truck. I think it’ll be good if it can tow about 7k to 8k. This has already been done on an air IRS Land Rover LR4 10 years ago. As far articulation/wheel travel, you may be more limited to break over angle but again the LR3/LR4 proved it was possible

[@morkovija]

Our dose of reason and common sense. Oh yeah!

[@thelos8093]

Sandy I'm gonna have to call you out on this... you used the ridgeline as for what a semi conventional independent rear suspension capabilities are? Maybe you should look into Humvees or maybe the oshkosh MRAP. They used basically the same suspension as a ridgeline but heavy duty military grade. That shows the real capabilities of non solid axle.

[@aknorth1053]

Could the tri motor have a dedicate motor for each rear wheel? maybe this would allow indepenent suspension? Also as a question if the exterior skin is the frame I am assuming you want to transfer the load to the frame? In that case would that make suspension less of a factor in towing capacity than a body on frame design?

[@Buddy308]

I think he pointed out that the Honda Ridgeline is constructed that way, but if transferring the towed load to the monocoque would increase towing capacity, Honda hasn't found a way to do it.

[@starwarsman2709]

The skin of the truck is sweet and strong to color the truck get digital wrap any color any design just make on computer put dimentions of truck or scan it and put wrap on then protected wrap clear and you have professional looking truck in your choice or go with a wrap off the shelf or change wrap just peel off and put new one on I love no paint bad for environment what do you think what design would you like to see or color on your ct

[@arkadiuszswitaj2620]

SUPER Cybertruck :D

[@xXZ31t6esTXx]

That spacer electrified transmission add is free?

[@taminabratbrat4030]

When it comes to the axles i think they are gonna be using independent suspension with u joints like the setup used in 8x8 armoured vehicles

[@turningpoint4238]

I saw a magnetic suspension system probably 30 years ago, possibly by MIT, that was driven over a curb. The car actually pulled up the wheels just before the curb, the car hopped on to the pavement with nothing felt in the car. Could the cybertruck using it's on board computer to predict and use the active suspension to smooth out the ride and even bank the vehicle through corners so the G-force isn't so horizontal?

[@DownunderGraham]

In the recent Jay Leno video, when Jay drives the cybertruck out of the parking lot I think I saw the rear right wheel lift into the air as the rear left wheel went down the curb at an angle. Would this imply that the rear axle is solid? I was quite surprised as it looked quite awkward at that point. (Edit) Ok. Just went back and rewatched the other video and the wheel wasn’t in the air, but it certainly looked awkward coming down the slope from the car park while turning onto the road. Maybe it’s just because it is such a huge slab of a truck.

[@erikkovacs3097]

In engineering terms there is no relation between body-on-frame solid axle and unibody independence suspension. It's just that unibody and independent suspension are newer and more modern so they tend to come together.

[@rollingtones1]

As of this date, there is still no exoskeleton Cybertruck. The one that’s running around is a mock up built on a body on frame chassis from another manufacturer. The actual exoskeleton cyber truck has not been built yet.

[@MyUniversalUniversity]

Great Job Sandy, thanks. I watched the CT unveiling. Elon said the air suspension and damping will be together. So maybe it is on the 40k truck as well. That makes it worth 7k more for the state of the art combination!! Tesla is going to make their own version on this one!!
